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

An organization is designing a storage strategy in Azure for two specific needs:

1. A shared file repository that must be concurrently accessed by multiple virtual machines using the SMB protocol.
2. Security audit logs that are accessed less than once a year, where latency is not a concern but storage cost must be minimized.

Which two of the following configurations should the organization select to meet these requirements?

  1. Azure Files to support the shared file repository using the SMB protocolAnswer
  2. Azure Blob Storage using the Archive access tier to store the security audit logsAnswer
  3. C
    Azure Blob Storage using the Archive access tier to allow immediate, direct read access to the security audit logs
  4. D
    Azure Disk Storage using the Archive access tier to store the security audit logs

Answer

Azure Files to support the shared file repository using the SMB protocol, and Azure Blob Storage using the Archive access tier to store the security audit logs.
Azure Files is correct because it supports concurrent access via the SMB protocol for multiple virtual machines, while Azure Blob Storage Archive tier is correct for the audit logs because it offers the lowest storage cost for rarely accessed data that does not require immediate retrieval.

Step-by-Step Solution

1
Analyze the first requirement: a shared file repository accessible by multiple VMs simultaneously via the SMB protocol.
Identify Azure Files as the native service that provides SMB-based shared file systems in Azure.
Azure Files is designed for shared developer or application tools, utility shares, and department shares, allowing concurrent SMB access.
2
Analyze the second requirement: security audit logs accessed less than once a year, with high tolerance for latency and a need to minimize cost.
Identify Azure Blob Storage Archive tier as the appropriate solution.
The Archive tier offers the lowest storage cost but requires data rehydration before access, which fits the low-frequency and non-urgent latency requirements.
3
Evaluate the incorrect options to confirm they do not meet the constraints.
Discard the options suggesting direct reading from Archive tier or using the Archive tier with Azure Disk Storage.
Archive tier blobs are offline and cannot be read directly, and Azure Disk Storage does not feature access tiers like Archive.

Key Concept

Azure storage services (Files, Blobs, Disks) and access tiers (Archive) must be aligned to specific workload requirements for access protocols and cost/retention profiles.
