To allow on-premises storage with built-in replication to Azure, which storage option would NOT meet the requirement?

Azure Blob Storage
Azure Data Lake Storage
Azure Table Storage
Azure Cosmos DB

The correct answer is: Azure Cosmos DB

When considering the need for on-premises storage with built-in replication to Azure, it's important to analyze the characteristics of each storage option. Azure Cosmos DB is designed for globally distributed applications and offers various replication models, such as multi-region writes and automatic failover. However, it is primarily a database service rather than a conventional storage solution aimed at simple file storage scenarios. Other storage options, such as Azure Blob Storage, Azure Data Lake Storage, and Azure Table Storage, provide storage capabilities that are more directly aligned with the scenarios requiring seamless integration with on-premises systems and built-in replication features. For instance, Blob Storage and Data Lake Storage are tailored for handling large amounts of unstructured data, with replication features that ensure data durability and availability across regions. Similarly, Table Storage, while simpler, provides an essential NoSQL datastore with storage capabilities that also benefit from Azure’s replication methods. Thus, Azure Cosmos DB, while versatile and powerful, does not fit the description of being suited for straightforward on-premises storage needs that require built-in replication in the same manner as these other Azure storage solutions. This makes it the least fitting option for the specified requirement.
