The correct answer should be C. The cosmos DB table api is compatible with Azure Table Storage api, just need to change few lines of code. and the Azure table storage api has uncertain latency and 20000 operation per second limitation.

Isn't it confusing how they choose D & write a comment that support C option? the funny thing, I've seen this in another forum and they also made the exact mistake. I wonder what is going on? Somebody is cheating and they are doing it very badly

If I have offices in 4 countries, I wouldn't care and will just pass the task to someone who already cleared the AZ-305/304 certification.

Answer..."C." "Azure Cosmos DB supports two indexing modes: 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: Indexing is disabled on the 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 be used to improve the performance of bulk operations. After the bulk operations are complete, the index mode can be set to Consistent and then monitored using the IndexTransformationProgress until complete."

The correct answer should be C. Cosmos DB latency for reads and writes, backed with <10-ms latency reads and <15-ms latency writes. Azure table storage is Fast, but no upper bounds on latency. https://docs.microsoft.com/en-us/azure/cosmos-db/table/table-support
