Queue

Explanation/Reference:
A queue keeps the order of the items.

Q229. Which three phrases are advantages of connection pooling? (Choose three.)

reduces time to create a connection

requires no configuration

reduces load on the server

improved scalability

improved performance

In connection pooling, after a connection is created, it is placed in the pool and it is used over again so that a new connection does not have to be established.
Connection pooling often improves application performance, concurrency and scalability.
Connection pooling also cuts down on the amount of time a user must wait to establish a connection to the database.

Q230. You need to create an application that processes data on a last-in, first-out (LIFO) basis.
Which data structure should you use?

Stack

Array

Tree

Queue

Q231. You have a server that limits the number of data connections.
What should you use to optimize connectivity when the number of users exceeds the number of available connections?

Named pipes

Normalization

Connection timeouts

Connection pooling

In software engineering, a connection pool is a cache of database connections maintained so that

Q232. You are creating a Web application. The application will be consumed by client computers that run a variety of Web browsers.
Which term is used to describe the process of making the application available for client computers to access?

Deploying

Hosting

Virtualization

Casting

You host web applications.

Q233. You are invoking a Web service method that returns an ArrayList object.
The client application is written is C#, whereas the Web service is written in Visual Basic.
The Web service is outside your corporate firewall.
You receive an “object not found” error when you call the method that returns the ArrayList object but can call other methods successfully from the same Web service.
What could be the problem?

The client and the Web service are not written in the same programming language.

The firewall is blocking all SOAP calls.

The client project does not contain a reference to the System.Collection namespace.

The ArrayList class cannot be serialized.

Q234. This question requires that you evaluate the underlined text to determine if it is correct.
Converting an object to a more general type is called upcasting.
Select the correct answer if the underlined text does not make the statement correct. Select “No change is needed” if the underlined text makes the statement correct.

No change is needed

downcasting

interfacing

flexing

Section: C#
Explanation/Reference:
Casting up a hierarchy means casting from a derived object reference to a base object reference.

Q235. You need an application that updates the inventory every morning when you log in to the workstation.
If an error occurs during update, the application needs to log messages to a text file.
The application doesn’t need any user interaction.
You want to automate the process that launches the application.
You want to minimize the efforts for developing, installing, and updating the application.
Which type of application should you create?

Windows Service

Windows Form

Web Form

console application

Q236. You need to ensure the data integrity of a database by resolving insertion, update, and deletion anomalies.
Which term is used to describe this process in relational database design?

Isolation

Normalization

Integration

Resolution

Database normalization is the process of organizing the fields and tables of a relational database to minimize redundancy. Normalization usually involves dividing large tables into smaller (and less redundant) tables and defining relationships between them. The objective is to isolate data so that additions, deletions, and modifications of a field can be made in just one table and then propagated through the rest of the database using the defined relationships.

Q237. This question requires that you evaluate the underlined text to determine if it is correct.
To minimize the amount of storage used on the hard drive by an application that generates many small files, you should make the partition as small as possible.
Select the correct answer if the underlined text does not make the statement correct. Select “No change is needed” if the underlined text makes the statement correct.

No change is needed

file allocation table

block size

folder and file names

Section: C#

Q238. Which type of function can a derived class override?

A Protected Overridable member function

A Shared function

A Private Overridable function

A non-overridable public member function

Explanation/Reference:
The Overridable modifier allows a property or method in a class to be overridden in a derived class.
You cannot specify Overridable or NotOverridable for a Private method.

Q239. Which language uses Data Definition Language (DDL) and Data Manipulation Language (DML)?

Java

C+ +

SQL

Pascal

SQL uses DDL and DML.

Q240. You are developing a new Windows service application.
The application contains three different Windows services.
Before these services can be used, they must be installed in the Windows service database. What action should you take to ensure that your services can be installed by a Windows installer tool?

Copy the service assembly to the global assembly cache.

Add an event log installer to the Windows service project.

Inherit the service from a ServiceBase class.

Add a service installer to the Windows service project.

Q241. You plan to create an application for your company.
The application will run automated routines and write the results to a text-based log file.
Little or no user interaction is required.
Security requirements on the host computers prevent you from running applications on startup, and users must be able to see the status easily on the screen.
The host computers also have limited memory and monitors that display only two colors.
These computers will have no network connectivity.
Which type of application should you use for this environment?

Windows Store app

console-based

DirectX

Windows Service

Building Console Applications
Applications in the .NET Framework can use the System.Console class to read characters from and write characters to the console. Data from the console is read from the standard input stream, data to the console is written to the standard output stream, and error data to the console is written to the standard error output stream.

Q242. You need to allow a consumer of a class to modify a private data member.
What should you do?

Provide a public function that assigns a value to the data member.

Create global variables in the class.

Assign a value directly to the data member.

Provide a private function that assigns a value to the data member.

In this example (see below), the Employee class contains two private data members, name and salary. As private members, they cannot be accessed except by member methods. Public methods named GetName and Salary are added to allow controlled access to the private members. The name member is accessed by way of a public method, and the salary member is accessed by way of a public read-only property.
Note: The private keyword is a member access modifier. Private access is the least
permissive access level. Private members are accessible only within the body of the class
or the struct in which they are declared
Example:
class Employee2
{
private string name = “FirstName, LastName”;
private double salary = 100.0;
public string GetName()
{
return name;
}
public double Salary
{
get { return salary; }
}
}

Q243. You are creating an application that presents users with a graphical interface in which they can enter data. The application must run on computers that do not have network connectivity.
Which type of application should you choose?

Console-based

Windows Forms

Windows Service

ClickOnce

Q244. Which two types of information should you include in an effective test case? (Choose two.)

the expected result from testing the case

multiple actions combined as a single step to test the case

any pre-conditions necessary to test the case

the stakeholders who originated the test case

You can create manual test cases using Microsoft Test Manager that have both action and validation test steps. You can also share a set of common test steps between multiple test cases called shared steps. This simplifies maintenance of test steps if your application under test changes.
