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

An administrator is planning an Azure Storage deployment and needs to identify the characteristics of different storage options and tiers. Which two of the following statements are correct?

  1. Azure Files provides fully managed file shares in the cloud that can be accessed using the industry-standard Server Message Block (SMB) protocol.Answer
  2. Data stored in the Archive access tier of Azure Blob Storage must be rehydrated to a Hot or Cool tier before it can be read.Answer
  3. C
    Data in the Archive access tier can be read directly and instantly with millisecond-level retrieval latency.
  4. D
    For Azure Disk Storage, Microsoft automatically manages and patches the operating system installed on the disk.

Answer

Azure Files provides fully managed file shares accessible via SMB, and data in the Archive access tier must be rehydrated to Hot or Cool before it can be read.
The option stating that Azure Files provides fully managed file shares via the SMB protocol is correct because SMB is the standard protocol for sharing files that Azure Files implements natively. The option stating that data in the Archive tier must be rehydrated is correct because the Archive tier is offline and requires rehydration to an online tier (Hot or Cool) before the data can be read.

Step-by-Step Solution

1
Evaluate the statement regarding Azure Files protocol support.
The statement is correct because Azure Files supports standard file sharing protocols such as Server Message Block (SMB).
This is a fundamental feature of Azure Files, enabling it to replace or supplement on-premises file servers.
2
Evaluate the statement regarding Archive tier access requirements.
The statement is correct because the Archive tier is offline and requires rehydration.
Data in the Archive tier cannot be accessed directly; it must be copied or moved to Hot or Cool storage (rehydrated) before reading.
3
Evaluate the statement about immediate access to the Archive tier.
The statement is incorrect because Archive storage is offline and has retrieval latency of several hours.
Immediate millisecond-level access is only available in online tiers like Hot and Cool.
4
Evaluate the statement about Azure Disk Storage OS patching.
The statement is incorrect because OS management on VM disks is a customer responsibility in IaaS.
Under the shared responsibility model, IaaS resources place the guest operating system maintenance on the customer, not Microsoft.
