Suggested Answer:
Scenario: Individual events must be immutable. Event data will be stored in Cosmos DB using the Document API.

Box 1: Strong -
Strong: Strong consistency offers a linearizability guarantee. The reads are guaranteed to return the most recent committed version of an item. A client never sees an uncommitted or partial write. Users are always guaranteed to read the latest committed write.

Box 2: Strong -
Strong: Strong consistency offers a linearizability guarantee. The reads are guaranteed to return the most recent committed version of an item. A client never sees an uncommitted or partial write. Users are always guaranteed to read the latest committed write.

Box 3: Consistent -
Azure Cosmos DB supports two indexing modes:
Consistent: If a container's indexing policy is set to Consistent, the index is updated synchronously as you create, update or delete items. This means that the consistency of your read queries will be the consistency configured for the account.
None: If a container's indexing policy is set to None, indexing is effectively disabled on that container. This is commonly used when a container is used as a pure key-value store without the need for secondary indexes. It can also help speeding up bulk insert operations.
