What are Azure blobs and what four access tiers are provided?
Show answer
Azure blob storage stores unstructured data. Blob storage can store any type of text or binary data. For example, images and video. The hot tier is optimized for frequent access of objects in the storage account. The cool tier is optimized for storing large amounts of data that is infrequently accessed and stored for at least 30 days. The cold tier is optimized for storing data that is infrequently accessed and stored for a minimum of 90 days. The cold tier has lower storage costs and higher access costs compared to the cool tier. The archive tier is optimized for data that can tolerate several hours of retrieval latency and will remain in the Archive tier for at least 180 days. -
Describe some of the security capabilities Azure Storage provides that enable developers to build secure applications.
Show answer
All data written to Azure Storage is automatically encrypted using Storage Service Encryption. You can use Microsoft Entra ID and Role-Based Access Control for both resource management and data operations. You can also use shared access signatures to delegate access to data object in Azure Storage. -
Blob containers support system properties and user-defined metadata, in addition to the data they contain. What is user-defined metadata and how it is specified?
Show answer
User-defined metadata consists of one or more name-value pairs that you specify for a Blob storage resource. You can use metadata to store additional values with the resource. Metadata values are for your own purposes only, and do not affect how the resource behaves
