Question

Difficulty: MediumCreate and Configure Virtual Machines

You are planning the deployment and configuration of several Azure virtual machines. Each virtual machine has specific performance, latency, or bootstrapping requirements.

Which Azure virtual machine configuration feature matches each deployment requirement?

  • Ephemeral OS diskStores the operating system directly on the local VM node's caching or temporary storage to eliminate storage transaction costs.
  • Proximity Placement GroupGroups virtual machines physically close to each other in the same Azure region to achieve the lowest possible network latency.
  • Ultra DiskAllows dynamic performance adjustments (IOPS and throughput) on-the-fly without restarting or deallocating the virtual machine.
  • Custom Script ExtensionDownloads and runs scripts on virtual machines to automate post-deployment configurations during provisioning.

Answer

Ephemeral OS disk matches local storage caching to eliminate cost. Proximity Placement Group matches physically grouping VMs to reduce latency. Ultra Disk matches dynamic performance adjustments. Custom Script Extension matches running scripts during provisioning.
Each feature matches its corresponding configuration requirement. Ephemeral OS disks eliminate storage costs by using local temp/cache storage. Proximity placement groups reduce latency by grouping VMs physically close. Ultra Disks support dynamic IOPS and throughput scaling. Custom Script Extensions automate VM provisioning tasks.

Step-by-Step Solution

1
Identify the storage characteristics of Ephemeral OS disks.
They reside on local node storage, eliminating remote storage costs.
To match Ephemeral OS disk with its description.
2
Identify the latency optimization characteristics of Proximity Placement Groups.
They physically place VMs close together in the same datacenter to minimize latency.
To match Proximity Placement Group with its network latency description.
3
Identify the unique capabilities of Ultra Disks.
They allow modifying IOPS and throughput dynamically without deallocating the VM.
To match Ultra Disk with its dynamic performance adjustment description.
4
Identify the configuration purpose of the Custom Script Extension.
It executes custom scripts on VMs during the provisioning phase.
To match Custom Script Extension with its script execution description.
