Difficulty: EasyBlob, File, and Disk Storage Solutions

You are designing an Azure storage solution for a company that is deploying a new logging application and a critical backup system. You have the following requirements:

1. The logging application requires high-performance managed disk storage to support continuous, low-latency write operations.
2. The critical backup files must remain highly available even if an entire Azure data center in the primary region suffers a complete power outage.

Which two storage configurations should you recommend to meet these requirements? (Select two.)

  1. Premium SSD Managed Disks for the logging applicationAnswer
  2. Zone-redundant storage (ZRS) for the critical backupsAnswer
  3. C
    Standard HDD Managed Disks for the logging application
  4. D
    Locally redundant storage (LRS) for the critical backups

Answer

The correct configurations are to use Premium SSD Managed Disks for the logging application and Zone-redundant storage (ZRS) for the critical backups.
Premium SSD Managed Disks provide the performance and low latency necessary for continuous write operations in a logging application, while Zone-redundant storage (ZRS) protects critical backups against datacenter-wide failures by replicating data across multiple physical zones.

Step-by-Step Solution

1
Determine the optimal disk type for the logging workload.
Premium SSD Managed Disks are selected because they support low latency and high IOPS required for active logging.
Standard HDD disks do not meet performance expectations for continuous, low-latency write operations.
2
Determine the required redundancy tier for the backup files to survive a datacenter outage.
Zone-redundant storage (ZRS) is selected because it replicates data across three separate zones.
Locally redundant storage (LRS) only protects against local hardware failures within a single datacenter and cannot survive a complete datacenter outage.

Key Concept

Selecting appropriate Azure storage tiers and redundancy options based on application performance requirements and disaster recovery constraints.
