NNY The default access tier for a new general-purpose v2 storage account is set to the hot tier by default. An append blob is composed of blocks and is optimized for append operations. When you modify an append blob, blocks are added to the end of the blob only, via the Append Block operation. Updating or deleting of existing blocks is not supported. Rehydrating a blob from the Archive tier can take several hours to complete.

For me the second should be true , I followed Bartin8tor link for append blobs and it clearly states that they are optimized for random read & writes. https://learn.microsoft.com/en-us/rest/api/storageservices/understanding-block-blobs--append-blobs--and-page-blobs

The answer is A. For NoSQL Here's why: Azure Cosmos DB for NoSQL supports the Core (SQL) API. This API allows you to query data stored in JSON documents using a SQL-like language. Other APIs: For Apache Gremlin: Used for graph databases, employs the Gremlin query language. For MongoDB: Leverages MongoDB's query language. For Table: Designed for storing and querying data in tables, similar to Azure Table storage. In summary: The Cosmos DB for NoSQL API, with its SQL-like syntax, provides a familiar way to query JSON documents within Azure Cosmos DB.

False. The default access tier of an Azure Storage account is the Hot access tier. False. Append blobs are optimized for sequential write operations, not random read and write operations. True. Retrieving data from the Archive access tier may take several hours to complete, depending on the size of the data and the retrieval options chosen.
