1. 1A web application needs request tracing and application performance monitoring through OpenTelemetry. Which Azure Monitor capability should the design use?

   1. A. Application Insights
   2. B. Azure Service Health
   3. C. Azure Activity Log
   4. D. Azure Network Watcher

   Answer: A

   Explanation: Microsoft describes Application Insights as offering "application performance monitoring (APM) for live web applications." It provides the required application telemetry rather than platform incidents, control-plane activity, or network diagnostics.

2. 2A SQL Server application requires an agent installed in the database host operating system and full OS administration. Which Azure SQL deployment meets these requirements?

   1. A. Azure SQL Database single database
   2. B. Azure SQL Database elastic pool
   3. C. Azure SQL Managed Instance
   4. D. SQL Server on Azure Virtual Machines

   Answer: D

   Explanation: "SQL virtual machines offer full administrative control over the SQL Server instance and underlying OS for migration to Azure." The PaaS choices do not expose the host OS.

3. 3A business will accept losing at most 15 minutes of committed data during a disaster. Which recovery objective does this requirement define?

   1. A. A 15-minute RPO
   2. B. A 15-minute RTO
   3. C. A 15-minute backup retention period
   4. D. A 15-minute availability measurement window

   Answer: A

   Explanation: RPO is "The maximum acceptable amount of data loss measured in time". It governs the acceptable recovery-point age rather than restoration duration.

4. 4A container platform must expose the native Kubernetes API and control plane for custom Kubernetes integrations. Which Azure service meets this requirement?

   1. A. Azure Container Instances
   2. B. Azure App Service
   3. C. Azure Container Apps
   4. D. Azure Kubernetes Service

   Answer: D

   Explanation: "Use AKS if you require access to the Kubernetes APIs and control plane." Container Apps hides those APIs, and the other options do not expose a Kubernetes control plane.

5. 5An architect must route Azure resource logs to an external SIEM that consumes a continuous event stream. Which diagnostic-setting destination should be selected?

   1. A. An Azure Storage account
   2. B. An Azure Event Hubs namespace
   3. C. A Log Analytics workspace
   4. D. An Azure Monitor workspace

   Answer: B

   Explanation: The Event Hubs destination can "Stream data to external systems such as non-Microsoft security information and event management (SIEM) solutions". This matches streaming to the SIEM.

6. 6A SQL Server workload uses CLR and must move to a fully managed Azure SQL service. Which deployment can preserve CLR support without VM administration?

   1. A. Azure SQL Managed Instance
   2. B. Azure SQL Database Hyperscale
   3. C. Azure SQL Database elastic pool
   4. D. SQL Server on Azure Virtual Machines

   Answer: A

   Explanation: "CLR isn't supported with SQL Database, but is supported in SQL Managed Instance." Managed Instance supplies that PaaS support; a VM retains VM administration.

   Reference: What is Azure SQL? — Business motivations — Administration

7. 7A workload must resume business operations within two hours after a disaster. Which recovery objective captures that requirement?

   1. A. A two-hour RPO
   2. B. A two-hour RTO
   3. C. A two-hour data-retention period
   4. D. A two-hour replication interval

   Answer: B

   Explanation: RTO is "The maximum acceptable time to restore business operations after a disaster occurs." The requirement concerns recovery duration, not data loss or retention.

   Reference: Architecture strategies for disaster recovery — Definitions — Recovery Time Objective

8. 8A team wants general-purpose container microservices with service discovery and event-driven scaling to zero, without managing Kubernetes APIs. Which service directly packages these capabilities?

   1. A. Azure Container Apps
   2. B. Azure Container Instances
   3. C. Azure Virtual Machines alone
   4. D. Azure Dedicated Host alone

   Answer: A

   Explanation: Container Apps "Enables event-driven application architectures by supporting scale based on traffic and pulling from event sources like queues, including scale to zero." It also provides microservice discovery without direct Kubernetes administration.

   Reference: Comparing Container Apps with other Azure container options — Azure Container Apps

9. 9Resource logs must remain in an audit archive with a policy that prevents modification. Which diagnostic-setting destination supports this design?

   1. A. Azure Storage with ordinary mutable blobs
   2. B. Log Analytics with a longer retention period
   3. C. Azure Storage with an immutability policy
   4. D. Event Hubs with a longer retention period

   Answer: C

   Explanation: For the Storage destination Microsoft states, "Send data to immutable storage to prevent its modification." This supplies the required archive immutability.

   Reference: Diagnostic settings in Azure Monitor — Destinations — Azure Storage account

10. 10A SaaS application has many Azure SQL databases with different, noncoincident demand peaks. Their compute capacity should be shared. Which deployment should the architect use?

    1. A. Independently provisioned single databases
    2. B. An Azure SQL Database elastic pool
    3. C. One provisioned database per virtual machine
    4. D. Independent serverless databases without pooling

    Answer: B

    Explanation: An elastic pool is "a collection of databases with a shared set of resources managed via a logical server." It supports shared capacity across the separate tenant databases.
