Difficulty: HardCreate and Configure Virtual Machines

A company is setting up a high-performance transactional database in the North Europe region. The database requires a virtual machine, which must be configured to achieve the following:

* Maintain write performance of up to 9000090{}000 IOPS and sub-millisecond latency on a dedicated data disk.
* Secure the workload against a localized datacenter outage.
* Apply automated software installations immediately after the OS starts.

Which two options must you configure for the virtual machine during deployment to support these requirements? (Select two.)

  1. Enable the Ultra Disk compatibility setting on the virtual machine during its creation.Answer
  2. Deploy the virtual machine into a specific Availability Zone.Answer
  3. C
    Configure the operating system (OS) disk to use Ultra Disk storage.
  4. D
    Place the virtual machine in an Availability Set.
  5. E
    Select a B-series virtual machine size.

Answer

Enable the Ultra Disk compatibility setting on the virtual machine during its creation, and deploy the virtual machine into a specific Availability Zone.
To support a workload requiring 9000090{}000 IOPS and sub-millisecond latency, Azure Ultra Disk storage is required. Ultra Disks can only be used if the virtual machine has the Ultra Disk capability enabled during creation. Additionally, Ultra Disks are zonal resources, meaning the virtual machine must be deployed in a specific Availability Zone, which also satisfies the requirement to protect against localized datacenter outages.

Step-by-Step Solution

1
Analyze the performance requirements (9000090{}000 IOPS and sub-millisecond latency).
Determine that Azure Ultra Disk is the only disk type that can meet these requirements, as Premium SSD (excluding v2) has lower limits and higher latency.
Ultra Disks support up to 160000160{}000 IOPS and sub-millisecond latency.
2
Identify the deployment constraints for Ultra Disks.
Ultra Disks require enabling the Ultra Disk capability on the VM during creation and must be deployed in an Availability Zone. They cannot be used as OS disks and are not supported in Availability Sets or B-series VMs.
Azure enforces these configuration requirements to ensure the VM is capable of routing I/O to the Ultra Disk subsystem.
3
Verify the availability and resiliency requirements.
Deploying the VM in an Availability Zone meets both the Ultra Disk requirement and protects the workload against localized datacenter outages.
Availability Zones provide physical separation within an Azure region to protect against datacenter failures.

Key Concept

Azure Ultra Disk requirements including VM capability enablement, Availability Zone placement, and disk role limitations.
