Difficulty: HardCreate and Configure Virtual Machines

You are configuring the deployment settings for an Azure virtual machine named VM1 in the East US region. VM1 will host a database server that has the following requirements:
- High-speed storage capability supporting up to 80,00080,000 IOPS.
- Zero storage costs for the operating system drive, with minimal write latency.
- Resiliency against datacenter-wide failures within the region.

Which two options should you select when creating VM1? (Select two.)

  1. Deploy VM1 to an Availability Zone.Answer
  2. Enable Ultra Disk compatibility on the virtual machine.Answer
  3. C
    Deploy VM1 to an Availability Set.
  4. D
    Create a subnet named BastionSubnet with a /28/28 prefix to host Azure Bastion for administrative access.

Answer

Deploying the virtual machine to an Availability Zone and enabling Ultra Disk compatibility on the virtual machine.
The correct configurations are deploying the virtual machine to an Availability Zone and enabling Ultra Disk compatibility on the virtual machine. Availability Zones provide protection against datacenter-wide failures. Enabling Ultra Disk compatibility is a prerequisite for attaching Ultra Disks, which are required to meet the high IOPS demand.

Step-by-Step Solution

1
Analyze the storage requirements for VM1.
The database workload requires up to 80,00080,000 IOPS, which exceeds the capabilities of standard storage options and requires the use of Ultra Disk storage.
Ultra Disks are necessary for workloads requiring very high IOPS and low latency.
2
Determine the availability and placement requirements for Ultra Disk storage.
Ultra Disks require deploying the virtual machine to an Availability Zone and enabling the Ultra Disk compatibility setting on the virtual machine during creation.
These configurations ensure the underlying infrastructure supports Ultra Disk attachments.
3
Analyze the high availability and resiliency requirements.
Protection against datacenter-wide outages requires deploying VM1 in an Availability Zone, which aligns with the requirement for Ultra Disk support.
Availability Zones provide datacenter-level redundancy, whereas Availability Sets only provide rack-level redundancy within a single datacenter.
