NEW QUESTION 41
Which Unity load balancing method will optimize performance in a customer environment if there are a limited number of open FC switch ports?

A Least I/O

Priority

Round Robin

Port to Core Affinity

Explanation
The best Unity load balancing method to optimize performance in a customer environment with a limited number of open FC switch ports is Port to Core Affinity. This method will assign the same port to the same core when possible. This allows the same switching resources to be used in the same cores, which will optimize performance due to reduced latency. Priority and Round Robin methods will also provide load balancing, but they are not as effective in a limited port environment. Least I/O is not recommended in this situation, as it will not provide adequate load balancing.

NEW QUESTION 43
When a remove replication operation is performed on a Dell EMC PowerStore array, what happens to the destination storage resource?

Is deleted

Stays in read/write mode

Stays in read-only mode

Taken offline

Explanation
“Removing a replication session is initiated on the source system by removing the protection policy from the Volume or Volume Group on the source system. Removing the protection policy from a storage resource results in the following: * The destination storage resource stays in read-only mode.”

NEW QUESTION 44
A systems administrator has deployed a Delf Unity XT 380F with 90x 1.92 TB SSDs in a dynamic pool How many drives are allocated as spare space1?

Explanation
When using a dynamic pool in Dell Unity XT systems, a certain number of drives are set aside as spare space to ensure that the system can continue to function in the event of a drive failure. The number of drives allocated as spare space depends on the number of drives in the pool, the RAID level in use, and the spare space policy.

NEW QUESTION 45
Which Dell EMC Midrange solution is configured for block storage with a built-in hypervisor?

Unity XT

PowerStore X

SC 9000

PowerStore T

The PowerStore X model configuration provides a hypervisor layer in addition to block storage.

NEW QUESTION 46
What tabs are available on the Dell EMC PowerStore Manager Dashboard?

Health. Overview. Performance, and Capacity

Health, Efficiency. Performance, and Summary

Performance. Efficiency, and Capacity only

Performance. Overview, and Capacity only

These categories are divided in tabs: Overview, Capacity, and Performance.

NEW QUESTION 47
What component or feature is provided by both the Dell EMC Power Store1000T array and the Dell EMC Unity XT 380 Series array?

Unified System

Container Integration

Configured Block with Hypervisor

NVMe disks

NEW QUESTION 48
What is the function of CMI on a Dell EMC Unity array?

Used for inter-SP communications

Acts as an extension of M.2 memory

Enables Vaulting to Disk

Handles API calls for HTTP client

Explanation
Common Messaging Interface (CMI): A high speed bus that is used for communication between SPs, such as mirroring write cache or redirecting I/Os from a non-optimized path.

NEW QUESTION 49
A Windows client using the SMB protocol is trying to access a multiprotocol file system from a Dell Unity XT NAS server. The local group database was checked and no mapping was found.
What is the next step in the SID to UID resolution process?

The Windows user access is removed

The domain controller is checked

The Windows user is mapped to the default UNIX account

Secmap is checked

Explanation
When a Windows client uses the SMB protocol to access a multiprotocol file system from a Dell Unity XT NAS server, the SID (Security Identifier) of the Windows user is mapped to a UID (User Identifier) on the UNIX file system. If no mapping is found in the local group database, the domain controller is checked to see if the SID is present there. The domain controller can provide the information needed to map the SID to the corresponding UID on the file system, allowing the Windows user to access the files. If the SID is not present in the domain controller, the Windows user’s access would be removed.

NEW QUESTION 50

NEW QUESTION 52
A customer wants to expand their Dell EMC Unity Hybrid system, which includes a pool of 64 drives in a RAID 5 (4+1) configuration. What is the minimum number of drives needed to expand the pool?

NEW QUESTION 53
What are characteristics of D@RE on a Dell EMC Unity array?

Impacts array only during implementation Has minimal impact on performance

Does not impact array during implementation Has some impact on performance for a moment

Impacts array for a moment after implementation
Has no impact on performance

Does not impact array during implementation Has minimal impact on performance

controller-based D@RE has minimal performance impact for typical mixed workloads, and no impact to other Dell EMC Unity data services due to the level at which the encryption is performed, which is after all data services have been applied. https://www.delltechnologies.com/en-us/collaterals/unauth/white-papers/products/storage/h15090-dell-emc-unity-data-at-rest-encryption.pdf

NEW QUESTION 54
What initiates an automatic NAS server failover to the peer SP?

Network link failure

Resource balancing algorithm

Assisted internal migration

SP hardware fault

Explanation
An SP hardware fault initiates an automatic NAS server failover to the peer SP in Dell Unity systems. This ensures that the NAS services remain available in case of hardware failure in one of the Storage Processors (SPs). The failover process is automatic and transparent to the hosts accessing the data, and it helps to maintain the high availability of the NAS services.
