NEW QUESTION 10
You are creating an app that uses Event Grid to connect with other services. Your app's event data will be sent to a servefless function that checks compliance. This function is maintained by your company.
You write a new event subscription at the scope of your resource. The event must be invalidated after 3 specific period of time. You need to configure Event Grid to ensure security.
What should you implement? To answer, select the appropriate options in [he answer area. NOTE: Each correct selection is worth one point

Answer:

Explanation: Box 1: SAS tokens
Custom topics use either Shared Access Signature (SAS) or key authentication. Microsoft recommends SAS, but key authentication provides simple programming, and is compatible with many existing webhook publishers.
In this case we need the expiration time provided by SAS tokens. Box 2: ValidationCode handshake
Event Grid supports two ways of validating the subscription: ValidationCode handshake (programmatic) and ValidationURL handshake (manual).
If you control the source code for your endpoint, this method is recommended.

NEW QUESTION 12
A construction company creates three-dimensional models from photographs and design diagrams of buildings. The company plans to store high-resolution photographs and blueprint files in Azure Blob Storage. The files are currently stored in the construction company’s office.
You are developing a tool to connect to Azure Storage, create container, and then upload the files. The tool must remain responsive to the end user while it is running and performing remote I/O operations. It must also wait for methods to complete before continuing.
You need to complete the configuration.
How should you complete the code? To answer, select the appropriate options in the answer area. NOTE: Each correct solution is worth one point.

Answer:

Explanation: Box 1: ProcessAsync();
Box 2: await cloudBlobContainer.CreatAsync();
If you specify that a method is an async method by using the async modifier, you enable the following two capabilities.
The marked async method can use await to designate suspension points. The await operator tells the compiler that the async method can't continue past that point until the awaited asynchronous process is complete. In the meantime, control returns to the caller of the async method.
The suspension of an async method at an await expression doesn't constitute an exit from the method, and finally blocks don’t run.
The marked async method can itself be awaited by methods that call it. References:

NEW QUESTION 17
You need to resolve the delivery API error. What should you do?

• A. Implement simple retry by using the EnableRetryOnFailure feature of Entity Framework.
• B. Implement exponential backoff by using the EnableRetryOnFailure feature of Entity Framework.
• C. Implement the Circuit Breaker pattern by using the EnableRetryOnFailure feature of Entity Framework.
• D. Invoke accustom execution strategy in Entity Framework.

Answer: A

Explanation: Scenario: The Delivery API intermittently throws the following exception:

A useful method to get rid of this error is to use RETRY LOGIC of Entity Framework 1.1.0 services.AddDbContext<DbContext>(options => options.UseSqlServer('yourconnectionstring',
…sqlServerOptionsAction: sqlOptions =>
…{
……sqlOptions.EnableRetryOnFailure(
………maxRetryCount: 5,
………maxRetryDelay: TimeSpan.FromSeconds(30),
………errorNumbersToAdd: new List<int>() { 19 });
…}));
In Retry logic, error 19 is not included. So you have to pass the error code 19 to set retry logic for error code 19.
