Zorluk: OrtaAzure Storage Accounts, Blob, Disk, Files, and Storage Tiers

An administrator stores database backup files in an Azure Storage account. To minimize costs, the backup blobs are kept in the Archive access tier. An auditor requests immediate access to read the contents of one of these backup files. Which of the following actions must the administrator take to allow the auditor to read the file?

  1. Rehydrate the blob by changing its access tier to Hot or Cool, or by copying it to a new blob in a Hot or Cool tier.Cevap
  2. B
    Generate a Shared Access Signature (SAS) token to allow the auditor to download and read the blob directly from the Archive tier.
  3. C
    Modify the container's public access level to allow direct read access to the archived blob over the internet.
  4. D
    Deploy an Azure Virtual Machine, attach the blob as a data disk, and contact Microsoft Support to configure the database engine and middleware on the VM to read it.

Cevap

Rehydrate the blob by changing its access tier to Hot or Cool, or by copying it to a new blob in a Hot or Cool tier.
Data in the Archive access tier is stored offline and cannot be read or modified directly. To read the contents of the blob, the data must first be rehydrated to an online tier (either Hot or Cool). This is done by changing the access tier of the blob to an online tier or by copying the archived blob to a new blob in the Hot or Cool tier.

Adım Adım Çözüm

1
Identify the current storage tier of the requested file.
The file is in the Archive tier, which is an offline tier optimized for rare access.
Blobs in the Archive tier are offline and cannot be read directly.
2
Determine the process required to bring the offline blob online.
The blob must undergo rehydration.
Rehydration is the process of moving a blob from the Archive tier to either the Hot or Cool tier.
3
Select the method to change the tier or duplicate the blob.
The administrator can change the blob's access tier directly or copy it to a new blob in an online tier.
Both actions successfully rehydrate the data, making it readable for the auditor.
