• Question 202:

  You develop an Azure web app. You monitor performance of the web app by using Application Insights.

  You need to ensure the cost for Application Insights does not exceed a preset budget.

  What should you do?

  A. Implement ingestions sampling using the Application Insights SDK.
  B. Set a daily cap for the Application Insights instance.
  C. Implement ingestion sampling using the Azure portal.
  D. Implement adaptive sampling using the Azure portal.
  E. Implement adaptive sampling using the Application Insights SDK.
  E. Implement adaptive sampling using the Application Insights SDK.

  ---

  Explanation

  Sampling is an effective way to reduce charges and stay within your monthly quota.

  You can set sampling manually, either in the portal on the Usage and estimated costs page; or in the ASP.NET SDK in the .config file; or in the Java SDK in the ApplicationInsights.xml file, to also reduce the network traffic.

  Adaptive sampling is the default for the ASP.NET SDK. Adaptive sampling automatically adjusts to the volume of telemetry that your app sends. It operates automatically in the SDK in your web app so that telemetry traffic on the network is reduced.

  Incorrect Answers:

  B: You can use the daily volume cap to limit the data collected.

  To change the daily cap, in the Configure section of your Application Insights resource, in the Usage and estimated costs pane, select Daily Cap.

• Question 203:

  DRAG DROP

  You maintain an existing Azure SQL Database instance. Management of the database is performed by an external party. All cryptographic keys are stored in an Azure Key Vault.

  You must ensure that the external party cannot access the data in the SSN column of the Person table.

  Will each protection method meet the requirement? To answer, drag the appropriate responses to the correct protection methods. Each response 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.

  Box 1: Yes

  You can configure Always Encrypted for individual database columns containing your sensitive data. When setting up encryption for a column, you specify the information about the encryption algorithm and cryptographic keys used to protect the data in the column.

  Box 2: No

  Box 3: Yes

  In SQL Database, the VIEW permissions are not granted by default to the public fixed database role. This enables certain existing, legacy tools (using older versions of DacFx) to work properly. Consequently, to work with encrypted columns (even if not decrypting them) a database administrator must explicitly grant the two VIEW permissions.

  Box 4: No

  All cryptographic keys are stored in an Azure Key Vault.

• Question 204:

  You need to store the user agreements.

  Where should you store the agreement after it is completed?

  A. Azure Storage queue
  B. Azure Event Hub
  C. Azure Service Bus topic
  D. Azure Event Grid topic
  B. Azure Event Hub

  ---

  Explanation

  Azure Event Hub is used for telemetry and distributed data streaming.

  This service provides a single solution that enables rapid data retrieval for real-time processing as well as repeated replay of stored raw data. It can capture the streaming data into a file for processing and analysis.

  It has the following characteristics:

  1. low latency 2. capable of receiving and processing millions of events per second

  3. at least once delivery

  https://docs.microsoft.com/en-us/azure/event-grid/compare-messaging-services

• Question 205:

  HOTSPOT

  You are developing a solution by using the Azure Event Hubs SDK. You create a standard Azure Event Hub with 16 partitions. You implement eight event processor clients.

  You must balance the load dynamically when an event processor client fails. When an event processor client fails, another event processor must continue processing from the exact point at which the failure occurred. All events must be aggregate and upload to an Azure Blob storage account.

  You need to implement event processing recovery for the solution.

  Which SDK features should you use? To answer, select the appropriate options in the answer area.

  Each correct selection is worth one point.

  

  

• Question 206:

  You are building a website that uses Azure Blob storage for data storage. You configure Azure Blob storage lifecycle to move all blobs to the archive tier after 30 days.

  Customers have requested a service-level agreement (SLA) for viewing data older than 30 days.

  You need to document the minimum SLA for data recovery.

  Which SLA should you use?

  A. at least two days
  B. between one and 15 hours
  C. at least one day
  D. between zero and 60 minutes
  B. between one and 15 hours

  ---

  Explanation

  The archive access tier has the lowest storage cost. But it has higher data retrieval costs compared to the hot and cool tiers. Data in the archive tier can take several hours to retrieve depending on the priority of the rehydration. For small objects, a high priority rehydrate may retrieve the object from archive in under 1 hour.

• Question 207:

  HOTSPOT

  You plan to develop an Azure Functions app with an Azure Blob Storage trigger. The app will be used infrequently, with a limited duration of individual executions.

  The app must meet the following requirements:

  Event-driven scaling

  Support for deployment slots

  Minimize costs

  You need to identify the hosting plan and the maximum duration when executing the app.

  Which configuration setting values should you use? To answer, select the appropriate values in the answer area.

  NOTE: Each correct selection is worth one point.

  Box 1: Consumption

  Hosting plan

  The Consumption plan is the cheapest.

  On the Consumption plan, instances of the Functions host are dynamically added and removed based on the number of incoming events.

  Service limits

  Deployment slots per app

  * Consumption plan -> 2

  * Dedicated plan -> 1 to 20

  * Premium plan -> 3 Box 2: 10

  Box 1: internal

  caching-type

  Choose between the following values of the attribute:

  1. internal to use the built-in API Management cache, 2. external to use the external cache as Azure Cache for Redis

  3. prefer-external to use external cache if configured or internal cache otherwise.

  4. Box 2: private

  downstream-caching-type

  This attribute must be set to one of the following values.

  1. none - downstream caching is not allowed.

  2. private - downstream private caching is allowed.

  3. public - private and shared downstream caching is allowed.

  Box 3: Authorization

  <vary-by-header>Authorization</vary-by-header>

  <!-- should be present when allow-private-response-caching is "true"-->

  Note: Start caching responses per value of specified header, such as Accept, Accept-Charset, Accept-Encoding, Accept-Language, Authorization, Expect, From, Host, If-Match

• Question 210:

  You are developing a microservice to run on Azure Container Apps for a company. External HTTP ingress traffic has been enabled.

  The company requires that updates to the microservice must not cause downtime.

  You need to deploy an update to the microservices.

  What should you do?

  A. Enable single revision mode.
  B. Use multiple environments for each container.
  C. Use a private container registry and single image for all containers.
  D. Use a single environment for all containers.
  E. Enable multiple revision mode.
  A. Enable single revision mode.

  ---

  Explanation

  Update

  As a container app is updated with a revision scope-change, a new revision is created. You can choose whether to automatically deactivate old revisions (single revision mode), or allow them to remain available (multiple revision mode).

  When in single revision mode, Container Apps handles the automatic switch between revisions to support zero downtime deployment.
