Question

Hotspot Question You have an Azure subscription that contains the storage accounts shown in the following table.

To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. Answer:

Options

• __typehotspot
• variantyes_no

Explanation

Lifecycle management is supported by all three storage account types, but the Archive tier is only supported by standard accounts without zone-redundancy, leaving only storage2 as a valid option.

Approach. For 'Lifecycle management', select 'storage1, storage2, and storage3'. Lifecycle management policies are supported across General-purpose v2 (StorageV2), Blob Storage, and Premium Block Blob (BlockBlobStorage) accounts. For 'The Archive access tier', select 'storage2 only'. The Archive tier is not supported on Premium BlockBlobStorage accounts (eliminating storage3). Additionally, the Archive tier is generally not supported for accounts configured with zone-based redundancy such as ZRS, GZRS, or RA-GZRS. Because storage1 uses GZRS, it cannot use the Archive tier. This leaves storage2, a BlobStorage account with RA-GRS, as the only account that supports moving data to the Archive access tier.

Common mistakes.

• common_mistake. A frequent error is selecting 'storage1' for the Archive tier because General-purpose v2 accounts normally support it. However, test-takers often overlook the redundancy constraint: Archive storage does not support GZRS or ZRS configurations. Another mistake is assuming Premium accounts (BlockBlobStorage) support capacity tiering to Archive.

Concept tested. Azure Storage Account Kinds, Redundancy configurations (RA-GRS vs. GZRS/ZRS), and their compatibility with blob Lifecycle Management and the Archive access tier.
