Microsoft AZ-204 Online Questions & Answers

• Question 361:

  DRAG DROP

  You are developing a serverless Java application on Azure. You create a new Azure Key Vault to work with secrets from a new Azure Functions application.

  The application must meet the following requirements:

  1. Reference the Azure Key Vault without requiring any changes to the Java code.

  2. Dynamically add and remove instances of the Azure Functions host based on the number of incoming application events.

  3. Ensure that instances are perpetually warm to avoid any cold starts.

  4. Connect to a VNet.

  5. Authentication to the Azure Key Vault instance must be removed if the Azure Function application is deleted.

  You need to grant the Azure Functions application access to the Azure Key Vault.

  Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

  Step 1: Create the Azure Functions app with a Consumption plan type.

  Use the Consumption plan for serverless.

  Step 2: Create a system-assigned managed identity for the application.

  Create a system-assigned managed identity for your application.

  Key Vault references currently only support system-assigned managed identities. User-assigned identities cannot be used.

  Step 3: Create an access policy in Key Vault for the application identity.

  Create an access policy in Key Vault for the application identity you created earlier. Enable the "Get" secret permission on this policy. Do not configure the "authorized application" or applicationId settings, as this is not compatible with a managed identity.

• Question 364:

  Note: This question is part of a series of questions that present the same scenario. Each Microsoft AZ-204 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.

  Margie's Travel is an international travel and bookings management service. The company is expanding into restaurant bookings. You are tasked with implementing Azure Search tor the restaurants listed in their solution.

  You create the index in Azure Search.

  You need to import the restaurant data into the Azure Search service by using the Azure Search NET SDK.

  Solution:

  1. Create a SearchServiceClient object to connect to the search index.

  2. Create a DataContainer that contains the documents which must be added.

  3. Create a DataSource instance and set its Container property to the DataContainer.

  4. Set the DataSource property of the SearchServiceCIient

  Does the solution meet the goal?

  A. Yes
  B. No
  B. No

  ---

  Explanation

  Use the following method: 1.Create a SearchIndexClient object to connect to the search index 2.Create an IndexBatch that contains the documents which must be added. 3.Call the Documents.Index method of the SearchIndexClient and pass the IndexBatch.

• Question 365:

  DRAG DROP

  You are developing an Azure solution.

  You need to develop code to access a secret stored in Azure Key Vault.

  How should you complete the code segment? To answer, drag the appropriate code segments to the correct locations. Each code segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

  NOTE: Each correct selection is worth one point.

  Box 1: SecretClient

  Var2 is the client, which is a SecretClient.

  Example:

  # ./shared/key_vault_secret.py

  import logging from azure.keyvault.secrets import SecretClient

  # Get a secret from Azure Key Vault def get_key_vault_secret(azure_credential, key_vault_name, secret_name):

  # TODO: Does this need to have hyphens stripped?

  key_vault_uri = f"

  https://{key_vault_name}.vault.azure.net"

  # Get the client client = SecretClient(vault_url=key_vault_uri, credential=azure_credential)

  # Get the secret key_vault_secret_response = client.get_secret(secret_name)

  return key_vault_secret_response.value

  Box 2: DefaultAzureCredential

  Get Azure credential with Python

  The code in this tutorial relies (example above) on the secure authentication to Azure with the Azure Identity package, using:

  Passwordless authentication - the most secure connection to Azure SDK object: DefaultAzureCredential

  Python implementation: get_azure_default_credential: Using the credential provided by the runtime environment such as needed by Azure Storage

• Question 366:

  You need to resolve the log capacity issue.

  What should you do?

  A. Create an Application Insights Telemetry Filter
  B. Change the minimum log level in the host.json file for the function
  C. Implement Application Insights Sampling
  D. Set a LogCategoryFilter during startup
  C. Implement Application Insights Sampling

  ---

  Explanation

  Scenario, the log capacity issue: Developers report that the number of log message in the trace output for the processor is too high, resulting in lost log messages.

  Sampling is a feature in Azure Application Insights. It is the recommended way to reduce telemetry traffic and storage, while preserving a statistically correct analysis of application data. The filter selects items that are related, so that you can navigate between items when you are doing diagnostic investigations. When metric counts are presented to you in the portal, they are renormalized to take account of the sampling, to minimize any effect on the statistics.

  Sampling reduces traffic and data costs, and helps you avoid throttling.
