IT Certification Exam Questions & Answers

In Tableau Server, schedules manage tasks such as extract refreshes and subscriptions. The execution mode of a schedule determines how tasks within that schedule are processed by the Backgrounder process:
* Parallel: Tasks run simultaneously (up to the Backgrounder’s capacity), which is the default setting.
* Serial: Tasks run one-at-a-time in sequence, ensuring that one task completes before the next begins.
To ensure tasks associated with a particular schedule run one-at-a-time, you must configure the schedule’s execution mode to Serial. This is done in the Tableau Server web interface:
* Go to Schedules.
* Select the schedule, click Actions > Edit Schedule.
* Under Execution, choose Serial instead of Parallel.
* Option A (Set Execution to Serial): Correct. This directly addresses the requirement by forcing tasks to execute sequentially.
* Option B (Set Default priority to 0): Incorrect. Priority (1-100) determines the order of task execution across all schedules, not whether tasks run one-at-a-time within a single schedule. Also, 0 is not a valid priority value (minimum is 1).
* Option C (Set Frequency to Hourly): Incorrect. Frequency (e.g., hourly, daily) controls when the schedule runs, not how tasks within it are executed.
* Option D (Set Execution to Parallel): Incorrect. Parallel execution allows tasks to run simultaneously, which contradicts the requirement.

/server/en-us/schedule_manage_create.htm).

Tableau Services Manager (TSM) is the administrative tool for managing Tableau Server’s configuration, processes, and topology. To log in to TSM (via the web UI at https://<server>:8850 or CLI), you need:
* TSM administrator credentials: These are distinct from site roles and are set during installation or reset via tsm reset.
* Local administrative rights: On Windows, the account used to access TSM must be in the local Administrators group on the initial node, as TSM interacts with system-level services.
In a test cluster, the engineer’s inability to log in suggests they lack either the correct TSM credentials or sufficient OS-level permissions. Since the question focuses on a Windows environment and “initial node,” the most immediate requirement is local administrative rights to run TSM commands or access the UI.
* Option C (An account with administrative rights to the computer): Correct. The engineer must use an account in the local Administrators group on the initial node to authenticate to TSM. After that, they’ ll need the TSM admin username/password set during installation.
* Option A (An account with a Creator site role): Incorrect. Site roles (e.g., Creator) apply to content access within Tableau Server, not TSM administration.
* Option B (An account with a Site Administrator role): Incorrect. Site Administrators manage site content, not server-level TSM functions.
* Option D (An account for the Tableau Server administrator): Partially correct but incomplete. This likely refers to the TSM admin account, but without local admin rights on the machine, login will fail.
Option C is more precise.

/en-us/tsm_overview.htm#authentication).

Abandoned workbooks-those no longer actively used-can clutter Tableau Server and consume resources (e.
g., disk space for extracts). Identifying them efficiently requires leveraging built-in administrative tools rather than manual or destructive methods. Let’s explore this in depth:
* Tableau Server Admin Views: Tableau provides pre-built administrative views to monitor server health, usage, and content. The Stale Content view, accessible under Server > Status > Administrative Views, is specifically designed to identify content (workbooks, data sources) that hasn’ t been viewed or modified recently. It shows:
* Content name, owner, and project.
* Last viewed date and last modified date.
* View count over a period.This view uses Repository data to track usage metrics, making it ideal for spotting abandoned workbooks.
* Option A (Use the Stale Content administrative view): Correct. This is the most efficient and non- invasive method. You can filter by last viewed date (e.g., >30 days ago) to identify workbooks with large extracts that users have stopped accessing. From there, you can contact owners or delete the content if policy allows. It’s a server administrator’s go-to tool for content management.
* Option B (Examine extract files in ProgramData/…/extract): Incorrect and impractical. The ProgramData/Tableau/Tableau Server/data/tabsvc/dataengine/extract directory stores .hyper extract files, but:
* File names are cryptic (e.g., GUIDs), not tied directly to workbook names.
* It doesn’t indicate usage or abandonment-only file presence and size.
* Manual inspection is time-consuming and error-prone compared to the Stale Content view.
* Option C (Delete all extracts and allow them to be re-generated): Incorrect and risky. Deleting extracts (e.g., via tsm maintenance cleanup) removes them without identifying usage. Regeneration only occurs if a schedule or user triggers it, potentially disrupting active users and losing historical data unnecessarily.
* Option D (View all workbooks, and sort by the Modified date): Partially effective but inefficient. In the Tableau Server UI (e.g., under Content > Workbooks), you can sort by “Last Modified,” but:
* It doesn’t show viewership (a workbook might be modified recently but unused).
* It’s manual and doesn’t scale for large deployments compared to the Stale Content view.
Why This Matters: The Stale Content view leverages Tableau’s metadata to provide actionable insights, saving time and reducing risk compared to manual or destructive alternatives. It’s part of Tableau’s governance toolkit.
Reference: Tableau Server Documentation – “Administrative Views” (https://help.tableau.com/current/server
/en-us/adminview_stale_content.htm).

Trusted Tickets is an authentication method in Tableau Server for embedding views in external applications (e.g., portals) without requiring users to log in manually. Here’s how it works:
* A trusted application (e.g., a web server) authenticates with Tableau Server using a trusted IP or username/password.
* Tableau Server issues a temporary ticket (a unique string).
* The ticket is embedded in a view URL (e.g., /trusted/<ticket>/views/…), granting access to the view for a short period (configurable, default 5 minutes).
* Option A (Access embedded views without being prompted for credentials): Correct. Trusted tickets enable SSO-like behavior for embedded content, bypassing the login prompt if the ticket is valid. This is ideal for seamless integration into external systems.
* Option B (Encrypt database connections): Incorrect. Encryption is handled by data source configurations (e.g., SSL), not trusted tickets, which focus on user authentication.
* Option C (Save and edit workbooks): Incorrect. Trusted tickets grant view access, not edit permissions-those depend on the user’s site role and permissions.
* Option D (Embed database credentials): Incorrect. Trusted tickets authenticate users to Tableau Server, not databases-database credentials are managed separately in the data source.
Why This Matters: Trusted tickets simplify embedding Tableau content securely in custom applications, enhancing user experience.
Reference: Tableau Server Documentation – “Trusted Authentication” (https://help.tableau.com/current/server
/en-us/trusted_auth.htm).

In a high-availability (HA) Tableau Server setup, the Repository (PostgreSQL) has an active and passive instance. Failover occurs if the active Repository fails. Let’s dive into the process:
* HA Setup:
* Two Repository instances across nodes (active/passive).
* Failover switches to the passive instance if the active one becomes unavailable (e.g., crash, network issue).
* Cluster Controller:
* Role: Monitors all processes (e.g., Repository, File Store) across nodes, detecting failures via heartbeats and status checks.
* Failover Decision: If the active Repository stops responding, Cluster Controller initiates failover, promoting the passive instance to active.
* Coordination: Works with Coordination Service (ZooKeeper) to update topology but makes the initial detection call.
* Option A (Cluster Controller): Correct.
* Why: It’s the watchdog process, constantly monitoring Repository health and triggering failover when needed.
* Option B (Coordination Service): Incorrect.
* Role: ZooKeeper maintains cluster state and coordinates topology updates post-failover, but doesn’t detect the failure-Cluster Controller does.
* Option C (Gateway): Incorrect.
* Role: Routes client requests-unrelated to internal process monitoring or failover.
* Option D (Backgrounder): Incorrect.
* Role: Executes background tasks-no involvement in Repository failover decisions.
Why This Matters: Understanding failover ensures HA reliability-Cluster Controller is the linchpin for resilience.
Reference: Tableau Server Documentation – “High Availability” (https://help.tableau.com/current/server/en-us
/ha.htm).

Tableau Server relies on several processes to function, each with a specific role. The Repository process (powered by PostgreSQL) serves as the database for metadata, storing critical information such as:
* User and group details.
* Permissions and site configurations.
* Workbook and data source metadata (e.g., schedules, subscriptions).
* Option B (Repository): Correct. The Repository is the centralized database that holds all metadata, making it the backbone of Tableau Server’s content management. There are typically two instances in an HA setup (one active, one passive), monitored by the Cluster Controller.
* Option A (Data Engine): Incorrect. The Data Engine manages in-memory data processing and extract storage (e.g., .hyper files), not metadata. It’s separate from the Repository.
* Option C (Backgrounder): Incorrect. The Backgrounder handles background tasks like extract refreshes and subscriptions, but it doesn’t store metadata-it interacts with the Repository to retrieve task details.
* Option D (File Store): Incorrect. The File Store manages physical extract files and workbook assets, not metadata, which is stored in the Repository.
Reference: Tableau Server Documentation – “Tableau Server Processes” (https://help.tableau.com/current
/server/en-us/processes.htm).

When a user reports slow performance for a newly-published workbook on Tableau Server, troubleshooting requires isolating the cause-e.g., data source issues, server load, workbook design, or caching. The first question should establish a baseline to narrow the scope. Let’s analyze this step-by-step with depth:
* Performance Context:
* A workbook’s speed depends on:
* Data Source: Query complexity, size, network latency (e.g., database vs. extract).
* Workbook Design: Filters, calculations, dashboard complexity.
* Server Resources: VizQL rendering, Backgrounder load, caching.
* “Newly-published” implies it’s not yet optimized or cached on the server.
* Option A (Does it run any faster in Tableau Desktop?): Correct.
* Why First: Comparing Desktop vs. Server performance is the most foundational diagnostic step:
* Desktop Baseline: If it’s slow in Desktop (local machine), the issue likely lies in the workbook (e.g., complex queries, large data) or data source (e.g., slow database)-not Server-specific.
* Server Difference: If it’s fast in Desktop but slow on Server, the problem could be server- side (e.g., resource contention, network latency to the data source from Server).
* Practical Next Steps:
* Slow in Desktop: Optimize workbook (e.g., simplify calcs, use extracts).
* Fast in Desktop: Check Server (e.g., caching, VizQL load).
* Why Critical: Establishes whether the issue is inherent to the workbook/data or introduced by Server-guides all further investigation.
* Option B (Does the workbook always run slowly or does performance vary?): Useful but secondary.
* Why Not First: Variability (e.g., slow at peak times) points to server load, but without a Desktop baseline, you can’t rule out workbook design. It’s a follow-up question after A.
* Detail: Variability might suggest caching or concurrent user impact, but it assumes Server-side causation prematurely.
* Option C (How many times have you opened the workbook in Tableau Server?): Less relevant initially.
* Why Not First: Frequency of access might affect caching (first load is slower, subsequent loads faster), but it’s too specific and doesn’t isolate Desktop vs. Server. It’s a niche follow-up.
* Option D (Did you enable caching on the workbook?): Misleading and incorrect.
* Why Not First: Caching is server-managed (e.g., VizQL cache settings via tsm data-access caching set), not a user-toggle per workbook. Users don’t “enable” it-admins do. Plus, it’s premature without a baseline.
Why This Matters: Starting with Desktop performance cuts through assumptions, pinpointing whether the root cause is client-side (workbook/data) or server-side-essential for efficient resolution in production.
Reference: Tableau Server Documentation – “Troubleshoot Performance” (https://help.tableau.com/current
/server/en-us/troubleshoot_performance.htm).

Tableau Server provides multiple methods to create groups (collections of users) and projects (content containers), catering to UI, CLI, and programmatic needs. Let’s dissect each option with depth:
* Option B (Tableau Server browser interface): Correct.
* Groups: Go to Users > Groups > Add Group, name it, and optionally sync with Active Directory.
* Projects: Go to Content > Projects > New Project, set name, description, and permissions.
* Details: The web UI is intuitive, requiring server/site administrator rights. It’s ideal for manual, ad-hoc creation with immediate visibility.
* Permissions: For projects, you can set default permissions or lock them here.
* Option C (tabcmd): Correct.
* Groups: tabcmd creategroup “GroupName” creates a local group. Add users with tabcmd addusers “GroupName” –users “user1,user2”.
* Projects: tabcmd createproject -n “ProjectName” -d “Description” creates a project.
* Details: tabcmd is a command-line tool for batch operations or scripting (e.g., automating group
/project setup). It requires a server admin login (tabcmd login).
* Limitation: No AD sync via tabcmd-that’s UI or REST API territory.
* Option D (REST API): Correct.
* Groups: Use the POST /api/api-version/sites/site-id/groups endpoint with a payload (e.g.,
{“group”: {“name”: “GroupName”}}). Supports AD import too.
* Projects: Use POST /api/api-version/sites/site-id/projects (e.g., {“project”: {“name”:
“ProjectName”, “description”: “Desc”}}).
* Details: The REST API is programmatic, ideal for integration with external systems or bulk automation. Requires authentication via a token and server/site admin rights.
* Power: Offers full control, including nested projects and custom permissions.
* Option A (tsm customize): Incorrect.
* Purpose: tsm customize modifies TSM UI branding (e.g., logos, colors) via commands like tsm customize –logo “path/to/logo.png”.
* Why Wrong: It’s unrelated to creating groups or projects-it’s for cosmetic server configuration, not content/user management.
Why This Matters: Offering UI, CLI, and API options ensures flexibility-manual for small tasks, automation for scale-critical in enterprise deployments.
Reference: Tableau Server Documentation – “Manage Groups” (https://help.tableau.com/current/server/en-us
/groups_create.htm), “Manage Projects” (https://help.tableau.com/current/server/en-us/projects_create.htm),

Tableau Server is designed for production environments and is supported only on server-class operating systems, not desktop operating systems. As of the latest documentation (aligned with knowledge up to March
21, 2025), the supported operating systems for Tableau Server on Windows are:
Windows Server 2016
Windows Server 2019
Windows Server 2022 (added in later versions, but relevant as of 2025).
Desktop operating systems like Windows 7 or Windows 10 are not supported for production installations due to stability, security, and performance requirements.
Option A (Windows 7): Incorrect. Windows 7 is a desktop OS and is not supported for Tableau Server. It’s also end-of-life as of January 2020.
Option B (Windows 10): Incorrect. Windows 10 is a desktop OS and not supported for production Tableau Server deployments, though it may be used for testing in non-production scenarios.
Option C (Windows Server 2019): Correct. This is a supported server OS for Tableau Server.
Option D (Windows Server 2016): Correct. This is also a supported server OS for Tableau Server.
Reference: Tableau Server Documentation – “System Requirements for Tableau Server” (https://help.tableau.
com/current/server/en-us/requirements.htm).

Tableau Server uses internal secrets (tokens) for secure communication between its processes (e.g., Repository, File Store). These are automatically generated during installation and can be regenerated if compromised or for security maintenance. The command to update these is:
* tsm security regenerate-internal-tokens: This regenerates the internal security tokens, ensuring all processes use the new tokens after a restart.
* Option C (tsm security regenerate-internal-tokens): Correct. This is the documented command for updating internal secrets.
* Option A (tsm data-access caching set -r 1): Incorrect. This command configures caching behavior, not security tokens.
* Option B (tsm licenses refresh): Incorrect. This refreshes license data, unrelated to internal secrets.
* Option D (tsm security validate-asset-keys): Incorrect. This validates encryption keys for assets, not internal tokens.
Reference: Tableau Server Documentation – “Regenerate Internal Tokens” (https://help.tableau.com/current
/server/en-us/cli_security.htm#regenerate-internal-tokens).

Table recommendations in Tableau Server suggest popular tables and data sources to users when they create new content in the web authoring environment. This feature is enabled by default but can be disabled at the site level.
Option A (Disable the option using the site Settings page): Correct. A site administrator can disable table recommendations by navigating to the site’s Settings > General page in the Tableau Server web interface and unchecking the option “Enable table recommendations.” This prevents users on that site from seeing these suggestions, offering a straightforward UI-based solution.
Option B (Use the command: tsm configuration set -k recommendations.enabled -v false): Incorrect. There is no recommendations.enabled key in the TSM configuration settings. This feature is managed per site, not server-wide via TSM.
Option C (Publish data sources only to projects with permissions locked): Incorrect. Locking permissions restricts access but doesn’t disable the recommendation feature itself. Users with access would still see recommendations.
Option D (Disable the option using the server Settings page): Incorrect. Table recommendations are a site- specific setting, not a server-wide setting. The server Settings page (via TSM) controls global configurations, not this feature.
Reference: Tableau Server Documentation – “Manage Site Settings” (https://help.tableau.com/current/server/en-us/site_settings.htm).

Subscriptions in Tableau Server deliver workbook views to users via email on a schedule. Group subscriptions apply to all group members-let’s unpack this:
* Group Subscription Mechanics:
* Created via Workbooks > Actions > Subscribe > Select Group.
* Delivers content to all users in the group at the time the subscription runs (e.g., daily PDF).
* Dynamic: Membership updates (additions/removals) are reflected automatically on the next run.
* Option C (The subscription updates automatically to include the new user): Correct.
* Details: When you add a user to the group (e.g., via Users > Groups > Add Users), Tableau Server’s subscription process queries the group’s current membership at runtime. The new user receives the subscription on the next scheduled delivery-no manual action needed.
* Example: Group “Sales” has a 9 AM subscription. Add a user at 8 AM-they get the email tomorrow at 9 AM.
* Option A (Admin receives notice to approve/deny): Incorrect.
* Why: No approval workflow exists for group membership changes in subscriptions-it’s automatic.
* Option B (Creator must manually edit): Incorrect.
* Why: Subscriptions are tied to the group, not a static user list-manual edits aren’t required for membership changes.
* Option D (Only members at creation time): Incorrect.
* Why: This would be true for individual subscriptions (static list), but group subscriptions are dynamic.
Why This Matters: Dynamic group subscriptions streamline content delivery as teams evolve, reducing admin overhead.
Reference: Tableau Server Documentation – “Manage Subscriptions” (https://help.tableau.com/current/server
/en-us/subscribe.htm).

Backing up Tableau Server ensures recovery from failures or migrations. A full backup includes multiple data types-let’s dissect this comprehensively:
* Backup Components:
* Repository Data: PostgreSQL database with metadata (users, permissions, workbooks). Backed up via tsm maintenance backup -f <filename>.tsbak.
* Configuration Data: Server settings (e.g., ports, authentication) also in the .tsbak file.
* Server Secrets: Encryption keys, internal tokens, Repository passwords-critical for restoring functionality.
* Extracts: .hyper files in File Store (optional, separate backup).
* Option A (Server secrets and Repository passwords): Correct.
* Details: Includes encryption keys (for extracts), internal tokens (process communication), and Repository credentials. Backed up separately or stored securely (e.g., tsm security export-keys).
* Why Critical: Without these, restored data may be inaccessible or services may fail.
* Option C (Configuration data): Correct.
* Details: Ports, authentication settings, process topology-part of the .tsbak file.
* Why Critical: Restores server behavior and connectivity post-recovery.
* Option D (Repository data): Correct.
* Details: Core metadata database-also in .tsbak.
* Why Critical: Without it, all content and user data is lost.
* Option B (Topology data): Incorrect.
* Details: Topology (process distribution) is part of configuration data in the .tsbak, not a separate entity. It’s not distinctly backed up as “topology data.” Why This Matters: A complete backup (secrets, config, repository) ensures full restoration-missing any piece risks an unusable server.
Reference: Tableau Server Documentation – “Back Up Tableau Server Data” (https://help.tableau.com/current
/server/en-us/backup_restore.htm).

Editing permissions on a workbook in Tableau Server depends on the user’s role and the project’s permission settings. Since permissions are not locked (i.e., “Managed by Owner”), let’s dissect who can edit them:
* Permission Model:
* Not Locked: Owners of content (workbooks, data sources) can set permissions, and Project Leaders can override at the project level.
* Site Roles: Define maximum capabilities (e.g., Viewer, Explorer, Creator).
* Capabilities: “Set Permissions” is explicit-only certain users get it.
* Option C (The workbook’s owner): Correct.
* Details: The owner (typically the publisher) has full control over their workbook when permissions are Managed by Owner:
* How: In the UI, go to Content > Workbooks > Actions > Permissions-owners can edit rules (e.g., grant Editor to a group).
* Site Role: Minimum of Explorer (can publish) or Creator to publish, ensuring “Set Permissions” capability.
* Why: Ownership inherently includes permission management unless locked.
* Option D (Users set to Project Leader for the workbook’s project): Correct.
* Details: Project Leaders are assigned via Content > Projects > Actions > Permissions > Set Project Leader:
* Power: Can edit permissions for all content in the project, even if not the owner.
* Site Role: Requires Site Administrator or Server Administrator (Creator/Explorer variants suffice).
* Why: Overrides ownership in Managed by Owner mode-ensures project-level governance.
* Option A (Users with project and workbook Viewer role): Incorrect.
* Why: Viewer role (site-level) limits users to viewing-lacks “Set Permissions” capability, regardless of project/workbook rules.
* Option B (Users with workbook Interactor role): Incorrect.
* Why: “Interactor” isn’t a standard role-likely a misnomer for Explorer or Viewer with interaction permissions (e.g., Filter). No permission-editing rights exist here.
Why This Matters: Knowing who can edit permissions prevents access control gaps-crucial for collaborative or regulated environments.
Reference: Tableau Server Documentation – “Permissions” (https://help.tableau.com/current/server/en-us
/permissions.htm), “Project Leader Permissions” (https://help.tableau.com/current/server/en-us
/permissions_project_leader.htm).

In an HA Tableau Server cluster, the Coordination Service (ZooKeeper ensemble) maintains cluster state- let’s find the best way to check it:
* Coordination Service:
* Runs on multiple nodes (3 or 5 in HA) to ensure quorum and failover.
* Status indicates if it’s running and synced-critical for cluster health.
* Option C (Run tsm status -v): Correct.
* Details: tsm status –verbose lists all processes across nodes, including Coordination Service (e.
g., “Coordination Service: RUNNING”).
* Why Best: Provides detailed, node-specific status in the CLI-e.g., “Node 1: RUNNING, Node
2: RUNNING.”
* Use: Run on the initial node; -v ensures full output.
* Option A (TSM web client Status page): Incorrect.
* Why: The TSM UI (Server > Status) shows process counts (e.g., “Coordination Service: 3 instances”), but not detailed per-node status-less granular than CLI.
* Option B (tsm maintenance ziplogs): Incorrect.
* Why: Generates log archives for troubleshooting, not a real-time status check.
* Option D (Tableau Server Status page): Incorrect.
* Why: The Server Status page (Server > Status in the web UI) monitors application processes (e.
g., VizQL), not TSM’s Coordination Service.
Why This Matters: Coordination Service health ensures HA stability-tsm status -v is the admin’s go-to for precision.
Reference: Tableau Server Documentation – “Check Server Status” (https://help.tableau.com/current/server/en- us/tsm_status.htm).

TSM commands manage Tableau Server maintenance-let’s validate their syntax:
* Command Requirements:
* Some need arguments (e.g., file paths); others are standalone.
* Valid and Complete: Must work as-is without errors.
* Option C (tsm maintenance cleanup): Correct.
* Details: Removes temporary files and old logs-no arguments required (optional flags like -l exist).
* Use: tsm maintenance cleanup-runs fully.
* Option D (tsm maintenance ziplogs): Correct.
* Details: Creates a zip of logs (e.g., tsm-logs.zip)-no arguments needed (optional -d for date range).
* Use: tsm maintenance ziplogs-complete and valid.
* Option A (tsm maintenance backup): Incorrect.
* Why: Requires -f <filename>.tsbak (e.g., tsm maintenance backup -f backup.tsbak)-incomplete without it.
* Option B (tsm maintenance restore): Incorrect.
* Why: Needs -f <filename>.tsbak (e.g., tsm maintenance restore -f backup.tsbak)-not standalone.
Why This Matters: Correct syntax ensures maintenance tasks execute without errors-critical for server health.
Reference: Tableau Server Documentation – “TSM Maintenance Commands” (https://help.tableau.com/current
/server/en-us/cli_maintenance_tsm.htm).

Tableau Server consists of multiple processes managed by TSM. When you stop Tableau Server (e.g., via tsm stop), most application processes halt, but some TSM-specific processes remain active to manage the server’s infrastructure. Let’s examine each:
* TSM Processes: These include the Administration Controller, Administration Agent, and License Manager, which handle configuration, monitoring, and licensing.
* Application Processes: These include VizQL Server, Backgrounder, Data Server, etc., which deliver Tableau’s core functionality and stop when the server is stopped.
When tsm stop is executed:
* The Administration Controller (port 8850) continues running to manage TSM operations (e.g., restarts, status checks).
* The License Manager remains active to validate licenses and ensure compliance, even when the server is offline.
* Application processes like VizQL Server and Backgrounder shut down, as they’re tied to user-facing services.
* Option B (License Manager): Correct. It persists to handle licensing tasks, ensuring the server can restart without license issues.
* Option D (Administration Controller): Correct. It’s the core TSM process, always running to accept commands and manage the server state.
* Option A (VizQL Server): Incorrect. VizQL stops, as it renders visualizations for users-an application process tied to active server operation.
* Option C (Backgrounder): Incorrect. Backgrounder stops, as it processes background tasks (e.g., extract refreshes), which halt when the server is down.
Why This Matters: Understanding which processes persist helps administrators troubleshoot and manage server lifecycle events effectively.
Reference: Tableau Server Documentation – “TSM Processes” (https://help.tableau.com/current/server/en-us
/tsm_overview.htm#processes).

The VizQL Server process in Tableau Server handles rendering visualizations and processing queries for users viewing dashboards or workbooks. During installation, Tableau Server automatically configures the number of VizQL instances based on the number of processor cores on the machine, following this rule:
Default VizQL instances = 2 per node, unless manually adjusted post-installation.
In multi-node setups, additional instances may be added based on core count, but the question specifies a single server with 16 cores.
The installer does not scale VizQL instances linearly with core count by default (e.g., it doesn’t set 1 instance per 4 cores). Instead:
For a single-node installation, the default is 2 VizQL instances, regardless of core count (assuming the minimum hardware requirements are met: 8 cores, 32 GB RAM).
Administrators can later adjust this using TSM (e.g., tsm topology set-process) based on performance needs, but the question asks for the default configured by the installer.
Option A (4): Incorrect. Four instances might be configured manually for a 16-core server, but it’s not the default.
Option B (6): Incorrect. Six instances exceed the default for a single node.
Option C (10): Incorrect. Ten instances are far beyond the default and would require manual configuration.
Option D (2): Correct. The installer sets 2 VizQL instances by default on a single-node installation.
Reference: Tableau Server Documentation – “Server Process Settings” (https://help.tableau.com/current/server
/en-us/processes.htm).

To force Tableau Server to require the setup of a new administrator account (e.g., resetting the server to an initial setup state), the tsm reset command is the appropriate tool. This command resets Tableau Server’s administrative configuration, including the TSM administrator account, while preserving content like workbooks and data sources.
Option B (Run the tsm reset command): Correct. Running tsm reset clears the current TSM administrator credentials and configuration settings. The next time you access TSM (e.g., via the web interface or CLI), it prompts you to set up a new administrator account, mimicking the initial setup process. Command: tsm reset — username <new-username> –password <new-password>.
Option A (Edit tabsvc.yml): Incorrect. The tabsvc.yml file contains service configuration data, but manually editing it is not supported or recommended for resetting the administrator account. It could also corrupt the installation.
Option C (Run the tsm register command): Incorrect. The tsm register command is used to register Tableau Server with a new product key or identity store, not to reset the administrator account.
Option D (Reinstall Tableau Server): Incorrect. Reinstallation wipes the entire server, including content, and is overkill for this task. The tsm reset command achieves the goal without data loss.
Reference: Tableau Server Documentation – “TSM Reset Command” (https://help.tableau.com/current/server
/en-us/cli_reset.htm).

Tableau Server uses a role-based licensing model with three primary license levels: Creator, Explorer, and Viewer. Each license level corresponds to specific site roles that define what users can do on the server.
Viewer License: This is the most restrictive license, allowing users to view and interact with published content (e.g., dashboards and visualizations) but not to create or publish new content.
Site Role: The Viewer license can only be associated with the Viewer site role. This role restricts users to viewing capabilities, aligning with the license’s purpose.
Option A (Creator): Incorrect. The Creator license is for users who can create, edit, and publish content using Tableau Desktop and the web interface. It corresponds to the Creator site role, not Viewer.
Option B (Explorer (can publish)): Incorrect. This is a variation of the Explorer license, which allows users to edit and publish content within limits. It’s more permissive than Viewer.
Option C (Viewer): Correct. The Viewer site role matches the Viewer license level perfectly.
Option D (Explorer): Incorrect. The Explorer license allows users to explore data and create content in the web interface, exceeding the Viewer license’s capabilities.
Reference: Tableau Server Documentation – “User Site Roles and Licenses” (https://help.tableau.com/current
/server/en-us/license_usage.htm).

Tableau Server’s performance and stability depend on dedicated resources and proper configuration. Running additional software on the same server is the most likely to cause problems because:
* Resource contention: Tableau Server requires significant CPU, RAM, and disk I/O. Other software (e.
g., databases, web servers) can compete for these resources, leading to slowdowns, crashes, or failed tasks.
* Port conflicts: Tableau uses specific ports (e.g., 80, 443, 8850), and other applications might interfere.
* Security risks: Additional software increases the attack surface, potentially compromising Tableau Server.
Tableau recommends running the server on dedicated hardware without unrelated applications.
* Option A (Running additional software on the server): Correct. This is a common cause of performance issues and is explicitly discouraged in Tableau’s best practices.
* Option B (Separating the Backgrounder and VizQL processes to different machines): Incorrect.
This is a supported multi-node configuration that can improve performance, not cause problems, if properly set up via TSM.
* Option C (Configuring the server to use a static IP address): Incorrect. A static IP is recommended for Tableau Server to ensure consistent network access, so it’s unlikely to cause issues.
* Option D (Using a non-default installation path): Incorrect. While not default, a custom path is supported (via TSM or installer options) and unlikely to cause problems if permissions and disk space are adequate.
