Designing and Implementing Cloud-Native Applications Using Microsoft Azure Cosmos DB — Question 38

You have an Azure subscription. The subscription contains an Azure Cosmos DB for NoSQL account named account1 that uses a default consistency level of Consistent Prefix.

You execute a SELECT query and specify the Consistent Prefix consistency level.

You need to execute a second SELECT query during the same session and specify a lower consistency level.

Which consistency level can be used for the second SELECT query?

Answer options

• A. Session
• B. Strong
• C. Bounded Staleness
• D. Eventual

Correct answer: D

Explanation

The correct answer is Eventual because it is a lower consistency level compared to Consistent Prefix. The Session, Strong, and Bounded Staleness levels are all stricter than Consistent Prefix, so they cannot be used in this scenario.
