Difficulty: MediumBlob, File, and Disk Storage Solutions

You are designing the storage infrastructure for a hybrid application suite in Azure. The design must accommodate the following two data requirements:

1. Data Ingestion: An external service will write large volumes of telemetry data via REST APIs. This data must remain accessible even in the event of a complete Azure region outage.
2. Database Workspace: A transaction processing database hosted on Azure Virtual Machines requires high-throughput data volumes that can sustain at least 16,00016,000 IOPS and sub-millisecond latency.

Which two storage solutions should you recommend? (Select TWO).

  1. Azure Blob Storage configured with Geo-Redundant Storage (GRS)Answer
  2. Premium SSD v2 Managed DisksAnswer
  3. C
    Azure Blob Storage configured with Locally Redundant Storage (LRS)
  4. D
    Standard SSD Managed Disks

Answer

Azure Blob Storage configured with Geo-Redundant Storage (GRS) and Premium SSD v2 Managed Disks
The correct storage solutions are Azure Blob Storage with Geo-Redundant Storage (GRS) and Premium SSD v2 Managed Disks. Azure Blob Storage with GRS ensures that the ingested telemetry remains available in the event of a primary region outage while supporting REST APIs. Premium SSD v2 Managed Disks provide the performance required by the database workspace, offering sub-millisecond latency and up to 80,00080,000 IOPS.

Step-by-Step Solution

1
Analyze the ingestion requirement for the external service.
The requirement specifies REST API access and the ability to survive a complete regional outage.
Azure Blob Storage supports HTTP/REST endpoints. To protect against a regional outage, Geo-Redundant Storage (GRS) is necessary as it replicates data asynchronously to a paired secondary region.
2
Analyze the database performance requirement.
The database needs volumes that can support at least 16,00016,000 IOPS and maintain sub-millisecond latency.
Premium SSD v2 managed disks are designed for latency-sensitive, high-performance workloads, supporting up to 80,00080,000 IOPS and sub-millisecond response times.
3
Evaluate the non-compliant options.
LRS storage accounts and Standard SSD managed disks are eliminated due to lack of geo-redundancy and high latency/low IOPS respectively.
Eliminating invalid configurations ensures the final design meets both disaster recovery and performance specifications.
