Difficulty: EasyCreate and Configure Virtual Machines

When deploying virtual machines in Azure, you must select the appropriate managed disk type for the OS and data disks based on performance and workload requirements. Match each Azure managed disk type to its primary characteristic.

  • Ultra DiskSupports sub-millisecond latency and allows dynamic adjustment of IOPS and throughput without restarting the virtual machine.
  • Premium SSDProvides high-performance, low-latency storage for production workloads and supports host caching.
  • Standard SSDProvides consistent, entry-level performance and latency, suitable for web servers and dev/test environments.
  • Standard HDDProvides low-cost, backup-oriented storage with variable latency, suitable for infrequently accessed data.

Answer

Ultra Disk matches with the ability to dynamically scale IOPS and throughput with sub-millisecond latency. Premium SSD matches with high-performance production workloads that support host caching. Standard SSD matches with consistent entry-level performance for web servers. Standard HDD matches with low-cost storage for infrequently accessed data.
Each Azure managed disk option is tailored to specific performance tiers. Ultra Disk supports dynamic configuration scaling and ultra-low latency; Premium SSD targets production workloads with host caching; Standard SSD targets entry-level servers with consistent SSD reliability; and Standard HDD offers budget-friendly storage for archival purposes.

Step-by-Step Solution

1
Examine Ultra Disk characteristics.
Ultra Disk is identified by its unique ability to dynamically modify performance metrics (IOPS and throughput) on-the-fly and deliver sub-millisecond latency.
To align the highest-tier storage option with its distinct flexibility features.
2
Analyze Premium SSD characteristics.
Premium SSD is matched to high-performance production workloads that utilize read-only or read-write host-level caching.
To identify standard enterprise-grade SSD properties.
3
Distinguish between Standard SSD and Standard HDD.
Standard SSD provides consistent, solid-state reliability for light production/dev-test workloads, while Standard HDD provides low-cost magnetic storage for backups and archival data.
To correctly map entry-level SSDs and traditional HDDs based on performance consistency and cost factors.
