Microsoft AI-200: Developing AI Cloud Solutions on Azure

Last checked October 22, 2026 against the official Microsoft exam page.

1. Question 1Develop AI solutions by using Azure data management services

   A RAG application stores product documents in Azure Cosmos DB for NoSQL and must find the items most similar to a query embedding. Which capability should the team enable on the container?

   1. AA vector index with a vector embedding policy on the embedding path
   2. BA hash-partitioned unique key constraint on the id path
   3. CMulti-region writes with session consistency enabled in Azure
   4. DA change feed lease container storing continuation tokens
   Show answer and explanationHide answer

   Correct answer: A

   Vector search in Cosmos DB for NoSQL requires a vector embedding policy that declares the path, dimensions, and distance function, plus a matching vector index. Multi-region writes affect availability, not similarity search, and the change feed only streams changes.

2. Question 2Secure, monitor, and troubleshoot Azure solutions

   A deployment script needs an API key for a language model. The security team requires that the key be rotated every 90 days without changing application code. Where should the key live?

   1. AHard-coded in source control with a comment noting the rotation schedule, in each environment
   2. BIn an Azure Key Vault secret with a rotation policy, read at runtime by a managed identity
   3. CIn a Dockerfile build argument passed with --build-arg baked into the image layer and visible in docker history
   4. DIn a Git tag annotation message attached to the release commit on the main branch
   Show answer and explanationHide answer

   Correct answer: B

   Key Vault stores the secret centrally, supports rotation, and the app reads the current version at runtime using a managed identity without credentials in code. Hard-coded or image-embedded secrets cannot be rotated without redeploying.

3. Question 3Develop containerized solutions on Azure

   A team keeps its Dockerfile in a Git repository and wants each commit to build the image inside Azure, with the result pushed to their Azure Container Registry without running a local Docker daemon. Which registry feature should they use?

   1. AAzure Image Builder
   2. BACR Tasks
   3. CAzure Automation runbooks
   4. DAzure DevOps Artifacts feeds
   Show answer and explanationHide answer

   Correct answer: B

   ACR Tasks builds and pushes container images inside the registry, and can be triggered by a source code commit or a base image update. Azure Image Builder produces virtual machine images, not container images, so it is the main distractor.

4. Question 4Connect to and consume Azure services

   An order service publishes order events, and a billing service must receive them reliably even if billing is offline for an hour. Messages that cannot be processed after several attempts must be kept for inspection. Which Azure Service Bus construct fits best?

   1. AStorage queue with visibility timeout of zero so messages reappear until processing succeeds
   2. BEvent Hubs partition with no retention configured, so consumers read each event once as it arrives
   3. CTopic with subscriptions, using the dead-letter queue of each subscription for poison messages
   4. DNotification Hubs installation that registers device tokens for push delivery
   Show answer and explanationHide answer

   Correct answer: C

   A topic with subscriptions gives each consumer its own durable copy, and messages that exceed the max delivery count move to that subscription's dead-letter queue for inspection. Event Hubs is built for streaming telemetry, and Storage queues lack topic subscriptions and built-in dead-letter handling of that kind.

5. Question 5Develop AI solutions by using Azure data management services

   A Cosmos DB workload is read-heavy but tolerates reads that may lag slightly behind writes, and the team wants to lower RU cost per read without losing ordering guarantees within a single session. Which consistency level best fits?

   1. AStrong
   2. BBounded staleness
   3. CSession
   4. DEventual
   Show answer and explanationHide answer

   Correct answer: C

   Session consistency gives read-your-writes and monotonic reads within a client session at a lower cost than strong consistency. Eventual has no ordering guarantees within a session, and strong consistency is the most expensive option for reads.
