An administrator is designing several Azure Virtual Machine (VM) deployments with specific performance, latency, and backup requirements. Match each Azure VM feature or configuration option to its primary technical constraint or characteristic.
- Ephemeral OS DiskStored on the local VM cache or temporary storage and does not support Azure Backup.
- Ultra DiskMust be deployed within an Availability Zone and cannot be used as a virtual machine OS disk.
- Proximity Placement GroupA logical grouping capability used to physically colocate VM resources within the same data center to reduce network latency.
- Custom Script ExtensionExecutes post-deployment scripts inside the guest OS, with a strict execution limit of 90 minutes before timing out.
Cevap
Ephemeral OS Disk matches local storage without Azure Backup support; Ultra Disk matches the requirement to be deployed in an Availability Zone and restricted from OS disk usage; Proximity Placement Group matches physically colocating VM resources to reduce network latency; Custom Script Extension matches post-deployment scripts with a 90-minute timeout.
The correct matches represent standard characteristics and boundaries defined by Azure: Ephemeral OS disks operate on local VM cache/temp disks without Azure Backup support; Ultra Disks are data-only and require an Availability Zone; Proximity Placement Groups physically colocate VMs to minimize latency; and Custom Script Extensions timeout after 90 minutes.
