A logistics company is designing an Azure storage infrastructure for a new IoT telemetry analysis and reporting application. The application has the following design requirements:

* Telemetry data must be stored in a cost-effective storage tier. The data is rarely accessed after 3030 days, but must be retained for 77 years for compliance. A rehydration latency of up to 1515 hours is acceptable when retrieving this archival data.
* Multiple containerized application servers running on Linux require concurrent read-write access to a shared file system via the NFS protocol.
* The report metadata database, which runs on an Azure Virtual Machine, requires a persistent managed disk with a capacity of 4 TiB4\text{ TiB} that must deliver at least 15000 IOPS15{}000\text{ IOPS} and sub-millisecond latency.

Which of the following design decisions should you recommend to meet these requirements? (Select TWO.)

  1. Store the telemetry data in Azure Blob storage and implement a lifecycle management policy to transition the blobs to the Archive tier after 30 days.Cevap
  2. Provision a Premium Azure Files share to support the NFS-based shared file system.Cevap
  3. C
    Use a Standard SSD managed disk for the database virtual machine to store the report metadata.
  4. D
    Configure the telemetry storage account to use Locally Redundant Storage (LRS) to ensure regional disaster resilience.

Cevap

Store the telemetry data in Azure Blob storage with a lifecycle management policy to transition the blobs to the Archive tier after 30 days, and provision a Premium Azure Files share to support the NFS-based shared file system.
Storing telemetry in Azure Blob storage combined with an Archive tier lifecycle transition meets the compliance, retention, and cost requirements while respecting the rehydration time limit. Deploying a Premium Azure Files share is the correct choice because NFS v4.1 support is only available in the Premium tier of Azure Files.

Adım Adım Çözüm

1
Analyze the requirements for telemetry data storage and identify the appropriate storage tier and lifecycle behavior.
Determine that Azure Blob storage with a lifecycle transition to the Archive tier after 3030 days is ideal, as the Archive tier accommodates the 1515-hour retrieval latency requirement at the lowest cost.
The Archive tier is designed for data that is rarely accessed and can tolerate retrieval latencies of up to several hours.
2
Evaluate the file share protocol requirements for the Linux containers.
Identify that a Premium Azure Files share is required to support the NFS v4.1 protocol.
Standard Azure Files shares support only SMB and REST protocols. NFS is exclusive to Premium Azure Files.
3
Assess the performance characteristics of the database disk.
Discard the use of Standard SSD or Standard HDD because they cannot provide 15000 IOPS15{}000\text{ IOPS} and sub-millisecond latency.
High-throughput and low-latency database workloads require Premium SSD, Premium SSD v2, or Ultra Disk.
