Microsoft Certified: Azure Administrator AssociateImplement and manage storageEasy
A developer is creating a new application that will store small, frequently updated configuration files and metadata. The application needs to retrieve data quickly with low latency and support simple queries based on key-value pairs. Which Azure storage service is most suitable for this scenario?
- AAzure Table Storage
- BAzure Blob Storage
- CAzure Data Lake Storage Gen2
- DAzure Queue Storage
Show answer & explanationAnswer & explanation
Correct answer: A. Azure Table Storage
Azure Table Storage is a NoSQL key-value store optimized for storing large amounts of structured, non-relational data. It provides fast access with low latency and is ideal for configuration files, metadata, and other data that can be efficiently queried using primary key and partition key.
Why the other options are wrong
- B. Azure Blob Storage is for unstructured data (blobs) and not optimized for key-value queries.
- C. Azure Data Lake Storage Gen2 is for big data analytics workloads, not small key-value configuration files.
- D. Azure Queue Storage is for storing messages between application components, not for persistent configuration data.
Azure Table Storage
Azure Table Storage is a NoSQL datastore that stores large amounts of structured, non-relational data. It is ideal for flexible datasets like web app user data, address books, device information, and other types of metadata.
- Key-value attribute store.
- Supports fast access with low latency.
- Cost-effective for large volumes of structured data.
Memory trick: Blob for files, Table for keys, Queue for messages.
