Difficulty: EasyAzure Storage Accounts, Blob, Disk, Files, and Storage Tiers

An administrator stores backup files in the Archive access tier of an Azure Storage account. The administrator now needs to read the contents of one of these files. What must the administrator do first?

  1. Rehydrate the file by copying or moving it to either the Hot or Cool access tier.Answer
  2. B
    Access the file directly using the storage account's primary blob endpoint URL.
  3. C
    Submit a support request for Microsoft to patch the operating system of the storage host.
  4. D
    Configure an Azure Backup policy to automatically make the archived file readable.

Answer

Rehydrate the file by copying or moving it to either the Hot or Cool access tier.
Data in the Archive access tier is stored offline to reduce storage costs. To read or modify this data, it must first be rehydrated to an online tier (such as the Hot or Cool tier). Rehydration can be accomplished by changing the blob's tier or by copying the archived blob to a new blob in an online tier.

Step-by-Step Solution

1
Identify the current storage tier of the file.
The file is currently in the Archive access tier, which is an offline tier used for long-term retention.
Understanding the status of the data is necessary since data in the Archive tier is not immediately accessible.
2
Determine the requirement to read the data.
The data must be brought online.
Azure Storage requires that offline archived blobs are rehydrated to an active online tier (either Hot or Cool) before their contents can be read or modified.
3
Select the appropriate operation to bring the data online.
Initiate a rehydration process to copy or change the tier of the blob to Hot or Cool.
Rehydration restores the blob to an online state, making it readable.

Key Concept

Azure Blob Storage Archive tier data is offline and must be rehydrated to the Hot or Cool tier before it can be read.
