Question

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

An organization is planning to use Azure Storage services for different workloads, including file sharing and long-term data backup. Which of the following statements are correct regarding Azure Storage services and access tiers? (Select two)

  1. Azure Files supports sharing files using the industry-standard Server Message Block (SMB) protocol.Answer
  2. Data stored in the Archive access tier of a Blob storage account must be rehydrated to the Hot or Cool tier before it can be read.Answer
  3. C
    Data in the Archive access tier can be read immediately with millisecond-level latency, but it incurs a higher retrieval cost than the Hot or Cool tiers.
  4. D
    When deploying an IaaS Virtual Machine, Microsoft automatically manages and optimizes disk storage costs by transitioning inactive operating system disks to the Archive access tier.

Answer

Azure Files supports sharing files using the industry-standard Server Message Block (SMB) protocol, and data stored in the Archive access tier of a Blob storage account must be rehydrated to the Hot or Cool tier before it can be read.
The correct options are the statements regarding Azure Files and the Archive access tier. Azure Files provides serverless file shares that support the SMB protocol, making it suitable for standard file-sharing workloads. The Archive access tier is designed for rarely accessed data, storing it offline at a low cost, which necessitates rehydration to Hot or Cool before the data can be read.

Step-by-Step Solution

1
Evaluate the file sharing capabilities of Azure Storage.
Azure Files is identified as the native service that provides fully managed file shares using the SMB protocol.
To verify if the statement about Azure Files and SMB is correct.
2
Evaluate the characteristics and retrieval behavior of the Archive access tier.
The Archive access tier is offline and requires rehydration (transitioning to Hot or Cool) before data can be accessed, which introduces latency of several hours.
To identify correct data access workflows and rule out immediate access claims for Archive storage.
3
Analyze the IaaS responsibility model and disk capabilities.
In IaaS, disk management and optimization are the customer's responsibility, and Azure Disk Storage does not support Blob-style access tiers such as Archive.
To evaluate and eliminate the incorrect statement regarding automatic managed disk tiering by Microsoft.

Key Concept

Understanding the protocols supported by Azure Files and the accessibility/rehydration requirements of the Archive storage tier.
