Latest Microsoft MCSD 70-487 Exam Practice Test Questions and Answers
QUESTION 1
You are developing an ASP.NET MVC application that reads and writes data from a SQL Server database.
You need to maintain data integrity including retrieving identical sets across reads in all situations that use transactions.
Which isolation level should you use?
A. Repeatable
B. Serializable
C. ReadUncommitted
D. ReadCommitted
Correct Answer: A
Explanation: REPEATABLE READ Specifies that statements cannot read data that has been modified but not yet
committed by other transactions and that no other transactions can modify data that has been read by the current
transaction until the current transaction completes.

moderate a comment. Which HTTP verb should you use?
A. GET
B. POST
C. DELETE
D. PUT
Correct Answer: D

C. aspnet_compiler.exe /t:code http://localhost:62965/UploadCallbackService.svc
D. aspnet_regiis.exe /t:code http://localhost:62965/UploadService.svc
E. svcutil.exe /t:code http://localhost:62965/UploadService.svc

QUESTION 4
You need to create an OData filter expression that returns books that match the following characteristics:
Published after 1/1/2000
Have “Science” as the first word
Which filter statement should you use?
A. B. C. D.
Correct Answer: A
QUESTION 5
You are developing an ASP.NET MVC application that displays a report. The report includes large images that are
stored in a database. Members of the EntityClient namespace are used to access the database through the ADO.NET
Entity
Framework data model.
You need to prevent memory exceptions while generating a report using the EntityDataRcader type.
Which CommandBehavior type should you use?
A. FastForwardReadOnly
B. SequentialAccess
C. SingleResult
D. SingleRow
Correct Answer: B
Explanation: SequentialAccess
Provides a way for the DataReader to handle rows that contain columns with large binary values. Rather than loading
the entire row, SequentialAccess enables the DataReader to load data as a stream.
QUESTION 6
You are developing an ASP.NET MVC application.
Applications can be deployed to remote servers only by administrators who have elevated privileges. The administrators
do not have access to Visual Studio 2012.
You need to select a deployment tool to deploy the application to remote servers for testing.
Which tool should you use?
A. Copy Web Site Tool
B. One-Click Publish
C. Publish Web Site Tool
D. Web Deployment Package
Correct Answer: D
QUESTION 7
ReportApp will shut down every night. However, data from the searches performed during the night must still be
collected.
You need to recommend a solution to meet the performance requirements for home.aspx.
What should you recommend?
A. ViewState
B. MemoryCache
C. OutputCache
D. ApplicationCache
Correct Answer: C
Scenario: When home.aspx is displayed, the rendered page must be cached for 10 minutes.
Page output caching
The output of an action method on a controller can be cached using the [OutputCache]attribute on the method. Actions
methods that return views will have the rendered page cached, while methods returning JSON data will have that data
saved. A number of properties on the OutputCacheAttribute class control how data is cached.
CacheProfile- If a number of methods will have the same cache settings, it makes sense to use the web.config file to
create a cache profile that can be used across all these methods.
The Duration attribute of the CacheProfile determines how long, in seconds, the output should be cached. To save an
item for 10 minutes, duration would be set to 600.
[OutputCache(Duration=600)]

QUESTION 8
You are developing an ASP.NET Core web application by using an Entity Framework code- first approach. The
application uses a SQLite database. You make changes to the classes in the model. You must apply the changes to
the
database.
You need to suggest an approach to reliably handle the Entity Framework migrations.
Which three actions should you perform? Each correct answer presents a part of the solution.
NOTE: Each correct selection is worth one point.
A. Modify the scaffolded migration script to drop the modified tables.
B. Run the following command: dotnet ef database update
C. Modify the scaffolded migration script to create new tables with the migration changes.
D. Modify the scaffolded migration script to drop the existing database and create the new database.
E. Run the following command: dotnet ef migrations add
Correct Answer: CDE
E: Run dotnet ef migrations add InitialCreate to scaffold a migration and create the initial set of tables for the model.
C: You can workaround some of the SQLite limitations by manually writing code in your migrations to perform a table
rebuild. A table rebuild involves renaming the existing table, creating a new table, copying data to the new table, and
dropping the old table.
D: SQLite does not support all migrations (schema changes) due to limitations in SQLite. For new development,
consider dropping the database and creating a new one rather than using migrations when your model changes.

QUESTION 9
You have a web application that was developed by using Microsoft ASP.NET MVC. The application is deployed to an
Azure web app and uses an Azure SQL Database.
From a development environment, you use Microsoft Visual Studio to change the application code, and you modify the
schema of the database.
You need to deploy the changes to Azure.
Which publishing method should you use?
A. BACPAC
B. FTP
C. Msdeploy
D. Robocopy
Correct Answer: A
You can deploy a .bacpac file to an Azure SQL Database using an Azure Resource Manager Template. .bacpac
contains the schema and data necessary to deploy your database.
Note: A BACPAC file is a ZIP file with an extension of BACPAC containing the metadata and data from a SQL Server
database. A BACPAC file can be stored in Azure blob storage or in local storage in an on-premises location and later
imported back into Azure SQL Database or into a SQL Server on-premises installation. References:
https://docs.microsoft.com/en-us/azure/sql-database/sql-database-export
QUESTION 10
You are developing a WCF service that compares several data sources. The service takes a long time to complete.
The service must meet the following requirements:
The client must be able to continue processing while the service is running. The service must initiate communication
with the client application when processing is complete.
You need to choose a message pattern to meet the requirements.
Which message pattern should you choose?
A. One Way
B. Streaming
C. Duplex
D. Request/Reply
Correct Answer: C
QUESTION 11
You are developing a web application by using Microsoft .NET Framework 4.5.
You are creating a web client for the application. The web client will make REST calls to several web services.
You need to ensure that the web client meets the following requirements:
Uses the Task class to perform asynchronous operations Reuses recently resolved DNS lookups
Which object should you include in the solution?
A. ServiceClient
B. WebClient
C. HttpClient
D. WebRequest
Correct Answer: C
References: https://www.c-sharpcorner.com/article/calling-web-api-using-httpclient/
QUESTION 12
You deploy a RESTful ASP.NET Web API to manage order processing.
You are developing an Azure App Services Web App to consume the API and allow customers to order products. You
use the HttpClient object to process order entries. The API throws SocketException errors when the Web App
experiences
a high volume of concurrent users.
You need to resolve the errors.
What should you do?
A. Implement a Using statement block when declaring the HttpClient object.
B. Increase the value of the Timeout property when declaring the HttpClient object.
C. Use the static modifier to declare the HttpClient object.
D. Create a new HttpClient instance for each API request and use asynchronous method calls.
Correct Answer: C
If the class that wraps the external resource is shareable and thread-safe, create a shared singleton instance or a pool
of reusable instances of the class.
The following example uses a static HttpClient instance, thus sharing the connection across all requests.
public class SingleHttpClientInstanceController : ApiController {
private static readonly HttpClient httpClient;
static SingleHttpClientInstanceController()
{
httpClient = new HttpClient();
}
// This method uses the shared instance of HttpClient for every call to GetProductAsync. public async Task
GetProductAsync(string id) {
var hostName = HttpContext.Current.Request.Url.Host; var result = await
httpClient.GetStringAsync(string.Format(“http://{0}:8080/api/…”, hostName));
return new Product { Name = result };
}
}
