NEW QUESTION # 138
You have an Azure Cosmos DB for NoSQL account that contains a container named container1.
You plan to use container1 as a key-value store that will perform point reads on the item ID and partition key.
You need to define an indexing policy for container! The solution must meet the following requirements:
* Provide the ability to set DefauitTimeToLive for container1.
* Minimize implementation time.
* Minimize costs.
How should you complete the JSON definition of the indexing policy? To answer, select the appropriate options in the answer area.

NEW QUESTION # 139
You have an Azure subscription.
You plan to implement an Azure Cosmos DB for NoSQL single-region write account named account1 that will replicate across two Azure regions.
You need to set the default consistency level for account1. The solution must meet the following requirements:
- Writes must be performed to a local majority in a single region.
- Reads must be performed from a local minority in a single region.
Which consistency level should you select?
Answer: B
Explanation:
Based on the Azure Cosmos DB architecture for a NoSQL single-region write account with two regions, the appropriate consistency level is Bounded Staleness.
Here is how this level maps to your specific requirements:
Writes to a Local Majority: For all consistency levels except Strong, Azure Cosmos DB performs writes to a local majority (three out of four replicas) within the primary write region before acknowledging the operation.
Reads from a Local Minority: In the Bounded Staleness and Strong consistency levels, reads are performed against a local minority (two replicas in a four-replica set) to compare log sequence numbers (LSN) and ensure consistency.
Single-Region Write vs. Strong Consistency: While Strong consistency also uses local minority reads, it requires a global majority for writes (acknowledgment from all regions), which contradicts your requirement for a "local majority" write.
Regional Behavior: Bounded Staleness is specifically recommended for single-region write accounts with multiple regions where "near strong" consistency is desired; it provides strong consistency guarantees for clients reading within the same region as the write.
Incorrect:
Other levels like Session, Consistent Prefix, and Eventual perform reads from only a single replica, which does not meet your "local minority" read requirement.
