QUESTION: 77

You are developing a web application that runs as an Azure Web App. The web application stores data in Azure SQL Database and stores files in an Azure
Storage account. The web application makes HTTP requests to external services as part of normal operations.
The web application is instrumented with Application Insights. The external services are OpenTelemetry compliant.
You need to ensure that the customer ID of the signed in user is associated with all operations throughout the overall system.
What should you do?

Add the customer ID for the signed in user to the CorrelationContext in the web application
On the current SpanContext, set the TraceId to the customer ID for the signed in user
Set the header Ocp-Apim-Trace to the customer ID for the signed in user
Create a new SpanContext with the TraceFlags value set to the customer ID for the signed in user

HOTSPOT (Drag and Drop is not supported)
You are developing an Azure Function App. You develop code by using a language that is not supported by the Azure Function App host. The code language supports HTTP primitives.
You must deploy the code to a production Azure Function App environment.
You need to configure the app for deployment.
Which configuration values should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:

See Explanation section for answer.

Answer(s): A

Explanation:

Box 1: Docker container
A custom handler can be deployed to every Azure Functions hosting option. If your handler requires operating system or platform dependencies (such as a language runtime), you may need to use a custom container. You can create and deploy your code to Azure Functions as a custom Docker container.
Box 2: PowerShell core
When creating a function app in Azure for custom handlers, we recommend you select .NET Core as the stack. A "Custom" stack for custom handlers will be added in the future.
PowerShell Core (PSC) is based on the new .NET Core runtime.
Box 3: 7.0
On Windows: The Azure Az PowerShell module is also supported for use with PowerShell 5.1 on Windows.
On Linux: PowerShell 7.0.6 LTS, PowerShell 7.1.3, or higher is the recommended version of PowerShell for use with the Azure Az PowerShell module on all platforms.

QUESTION: 79

DRAG DROP (Drag and Drop is not supported)
You provision virtual machines (VMs) as development environments.
One VM does not start. The VM is stuck in a Windows update process. You attach the OS disk for the affected VM to a recovery VM.
You need to correct the issue.
In which order should you perform the actions? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Select and Place:

See Explanation section for answer.

Answer(s): A

Explanation:

Remove the update that causes the problem
1. Take a snapshot of the OS disk of the affected VM as a backup.
2. Attach the OS disk to a recovery VM.
3. Once the OS disk is attached on the recovery VM, run diskmgmt.msc to open Disk Management, and ensure the attached disk is ONLINE.
4. (Step 1) Open an elevated command prompt instance (Run as administrator). Run the following command to get the list of the update packages that are on the attached OS disk: dism /image:<Attached OS disk>:\ /get-packages > c:\temp\Patch_level
5. (Step 2) Open the C:\temp\Patch_level.txt file, and then read it from the bottom up. Locate the update that's in Install Pending or Uninstall Pending state.
6. Remove the update that caused the problem:
dism /Image:<Attached OS disk>:\ /Remove-Package /PackageName:<PACK
7. (Step 4) Detach the OS disk and recreate the VM. Then check whether the issue is resolved.

QUESTION: 80

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You develop an HTTP triggered Azure Function app to process Azure Storage blob data. The app is triggered using an output binding on the blob.
The app continues to time out after four minutes. The app must process the blob data.
You need to ensure the app does not time out and processes the blob data.
Solution: Update the functionTimeout property of the host.json project file to 10 minutes.
Does the solution meet the goal?

Yes
No

Answer(s): B

Explanation:

Instead pass the HTTP trigger payload into an Azure Service Bus queue to be processed by a queue trigger function and return an immediate HTTP success response.
Note: Large, long-running functions can cause unexpected timeout issues. General best practices include:
Whenever possible, refactor large functions into smaller function sets that work together and return responses fast. For example, a webhook or HTTP trigger function might require an acknowledgment response within a certain time limit; it's common for webhooks to require an immediate response. You can pass the
HTTP trigger payload into a queue to be processed by a queue trigger function. This approach lets you defer the actual work and return an immediate response.
