Q141

What happens when you exceed the provisioned throughput of a Cosmos DB container?

  • A Requests are throttled
  • B All requests succeed
  • C The database crashes
  • D Data is deleted
Explanation When throughput is exceeded, requests that exceed limits are throttled; other options do not accurately depict the outcome.
Q142

Which feature allows you to provide low-latency access to globally distributed data in Azure Cosmos DB?

  • A Multi-region replication
  • B Query indexing
  • C Throughput provisioning
  • D Change feed
Explanation Multi-region replication ensures data is accessible from multiple Azure regions, minimizing latency. The other options do not specifically target low-latency data access across regions.
Q143

A company needs to ensure that their multi-tenant application can effectively scale its database while also ensuring isolation among tenants. What should they use?

  • A Single database with shared throughput
  • B Multiple databases per tenant
  • C Partitioning by tenant ID
  • D Shared container with resource tags
Explanation Using multiple databases for each tenant provides effective isolation and scaling benefits. The other options either share resources or complicate isolation.
Q144

What happens when you exceed the provisioned throughput in Azure Cosmos DB?

  • A Requests are throttled
  • B Data is deleted
  • C Backup operations fail
  • D Service is automatically upgraded
Explanation Requests that exceed provisioned throughput are throttled to maintain performance and availability. The other options do not accurately reflect the behavior of Azure Cosmos DB under high load.

  • B Azure Resource Manager
  • C Azure Front Door
  • D Azure Cosmos DB Multi-Region Write

  • A Change Feed
  • B Triggers
  • C Stored Procedures
  • D Continuous Backup
Explanation Change Feed allows real-time capture of changes, unlike the other options which serve different functions.
Q147

What happens when you exceed the provisioned throughput in Azure Cosmos DB?

  • A Requests are throttled instantly
  • B Throughput is automatically upgraded
  • C All read requests are denied
  • D Requests are processed without limits
Explanation Requests that exceed throughput are throttled, while the other options inaccurately describe the behavior.
