AI-200 mock exam

Question 1, Develop containerized solutions on AzureA Container App worker should scale with the length of a Service Bus queue and drop to zero replicas when idle. What do you configure?

• AA larger container image
• BA fixed replica count of ten
• CAn App Service plan upgrade
• DA KEDA scale rule on the queue

Question 2, Develop containerized solutions on AzureYou want builds to run in Azure and push images to your registry without Docker on the CI agent. What should you use?

• AAzure Container Apps jobs
• BAzure Container Registry Tasks
• CAzure App Service deployment slots
• DAzure Kubernetes Service node pools

Question 3, Develop AI solutions by using Azure data management servicesCosmos DB queries on a rarely used property cost too many RUs, and writes are also expensive. What should you review?

• AThe consistency level, set to strong for all reads
• BThe partition count in the client SDK settings
• CThe container image tag used by the API
• DThe indexing policy, and include only the paths you query

Question 4, Develop AI solutions by using Azure data management servicesA pgvector similarity query on 20 million rows is too slow, and sequential scans show up in the plan. What is the most direct fix?

• AMove the table to Blob Storage and scan it from a Function
• BIncrease the client connection timeout and the pool size
• CAdd an approximate index such as HNSW on the embedding column
• DConvert the embeddings to text columns and use full-text search

Question 5, Develop AI solutions by using Azure data management servicesYou need to react to every new or updated item in Cosmos DB to refresh embeddings. Which feature fits?

• AA scheduled export to CSV
• BA manual reindex button
• CThe change feed processor
• DA nightly full table scan

Question 6, Connect to and consume Azure servicesA message keeps failing processing and is retried until it hits the maximum delivery count. Where does Service Bus put it?

• ABack at the head of the queue forever
• BThe dead-letter queue
• CAzure Key Vault
• DIt is silently deleted

Question 7, Connect to and consume Azure servicesSeveral subscribers should react to custom events, and each wants only some event types. Which service is built for this?

• AAzure Cosmos DB with the change feed
• BAzure Container Registry with webhooks
• CAzure App Configuration with refresh
• DAzure Event Grid with filters

Question 8, Secure, monitor, and troubleshoot Azure solutionsA request crosses three services and you need to see where the latency sits. What do you instrument?

• AA bigger App Service plan so the slow service has more room
• BA daily log export that you can compare in a spreadsheet
• CDistributed tracing with OpenTelemetry SDKs
• DKey Vault rotation to rule out expired credentials
