Question

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

An organization is planning to migrate its workloads to Microsoft Azure and has identified two key storage requirements:
1. A shared file system that can be mounted simultaneously by multiple Azure Virtual Machines and on-premises servers using the SMB protocol.
2. A cost-effective storage tier for infrequently accessed logs that must remain immediately readable without any rehydration delay.

Which two of the following Azure Storage features or tiers should the organization select to meet these requirements?

  1. Azure Files to host the shared file system.Answer
  2. The Cool access tier to store the logs.Answer
  3. C
    The Archive access tier to store the logs.
  4. D
    Azure Disk Storage to host database files, assuming Microsoft manages the database software configuration.

Answer

To meet the requirements, the organization should select Azure Files for the shared file system and the Cool access tier for the storage of infrequently accessed logs.
Azure Files is the correct choice for the shared folder because it natively supports the SMB protocol for concurrent access across multiple systems. The Cool access tier is correct for the logs because it provides a cost-effective option for infrequently accessed data while maintaining online status for immediate reads.

Step-by-Step Solution

1
Analyze the first requirement: a shared file system accessible via the SMB protocol.
Identify Azure Files as the native managed file share service in Azure that supports SMB and can be concurrently mounted.
Azure Files is designed for shared file storage, whereas Azure Disk Storage is block storage dedicated to a single virtual machine.
2
Analyze the second requirement: a cost-effective storage tier for infrequently accessed logs that must be immediately readable.
Identify the Cool access tier as the appropriate tier.
The Cool tier offers lower storage costs than the Hot tier with immediate access. The Archive tier offers the lowest storage costs but requires a time-consuming rehydration process before data can be read.
3
Evaluate and eliminate incorrect service configurations.
Eliminate the Archive access tier due to rehydration latency, and eliminate Disk Storage managed database configurations since database patching is a customer responsibility in IaaS.
Under the shared responsibility model, IaaS VM resources like Disk Storage place the configuration and patching of application software (like databases) on the customer.

Key Concept

Understanding the differences between Azure storage services (Azure Files, Azure Disk Storage) and storage access tiers (Hot, Cool, Archive), as well as the shared responsibility model's application to virtual machine storage.
