Worked practice questions

Which Azure Container Registry feature reduces image pull latency for a multi-region Kubernetes deployment?

  1. ACR geo-replication
  2. ACR public anonymous access
  3. Disabling image scanning
  4. Storing all images in a single Region forever
Show answer and solution

Correct answer: A. ACR geo-replication

Geo-replication mirrors an ACR registry across regions so AKS clusters pull from the nearest replica. The other options compromise security or latency.

Which Azure storage service offers a globally-distributed multi-model database with multi-region writes and single-digit-ms latency?

  1. Azure Cosmos DB
  2. Azure Bastion
  3. Azure Functions
  4. Azure Blob Storage
Show answer and solution

Correct answer: A. Azure Cosmos DB

Cosmos DB is the multi-model globally-distributed DB. Blob is object storage; Functions are compute; Bastion is jump-host.

Which Cosmos DB API exposes a SQL-like query interface against JSON documents — the default and most-used API?

  1. MongoDB API
  2. Cassandra API
  3. Gremlin (graph) API
  4. NoSQL API (formerly Core / SQL API)
Show answer and solution

Correct answer: D. NoSQL API (formerly Core / SQL API)

The NoSQL / Core API is Cosmos's native JSON-document API. Cassandra, MongoDB, Gremlin are alternative API surfaces.
