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

A company plans to migrate its historical compliance logs to Azure Blob Storage and assign them to the Archive access tier to minimize costs. A developer needs to retrieve information from one of these archived logs to troubleshoot an application issue. Which of the following describes the requirement for reading the data stored in this tier?

  1. The blob must be rehydrated to either the Hot or Cool access tier before it can be read.Cevap
  2. B
    The blob can be read directly, but the read operation will experience latency of several hours while the storage system prepares the data stream.
  3. C
    The blob can only be read after the customer manually patches the operating system of the underlying storage hosting infrastructure.
  4. D
    The blob can be read directly only if a ReadOnly resource lock is applied to the containing storage account.

Cevap

The blob must be rehydrated to either the Hot or Cool access tier before it can be read.
The correct answer is correct because the Archive access tier in Azure Blob Storage is an offline tier. Blobs in this tier cannot be read directly. In order to read the data, they must be rehydrated, which means changing their tier to Hot or Cool, or copying them to a new blob in an online tier.

Adım Adım Çözüm

1
Identify the state of data stored in the Archive access tier.
The data is stored offline and is not immediately accessible.
The Archive tier offers the lowest storage costs but does not support direct, real-time read access.
2
Determine the process required to access offline data.
The blob must be rehydrated.
To retrieve data from an offline blob, it must be transitioned to an online tier (Hot or Cool) or copied to an online tier.
3
Evaluate the retrieval latency associated with rehydration.
The rehydration process will take several hours depending on the chosen priority (Standard or High).
Rehydration is not instantaneous and requires time to copy the offline blocks back to active storage.
