Difficulty: HardCreate and Configure Virtual Machines

You plan to deploy an Azure Virtual Machine named VM1 in the East US region. VM1 will host a transaction-heavy database engine. You need to configure VM1 to satisfy the following requirements:
- Ensure the database files are stored on a disk that supports up to 80,000 IOPS and sub-millisecond latency.
- Protect the virtual machine against datacenter-wide failures.
- Allow VM1 to be placed in the backend pool of an existing public load balancer.
- Configure daily backups for the virtual machine.

Which configuration should you choose when deploying VM1?

  1. Deploy VM1 in Availability Zone 1, select a VM size that supports Ultra Disk, enable Ultra Disk compatibility, associate the VM with a Standard SKU load balancer, and configure backups to a Recovery Services Vault in the East US region.Answer
  2. B
    Deploy VM1 in a new Availability Set with three fault domains, select a VM size that supports Ultra Disk, enable Ultra Disk compatibility, associate the VM with a Standard SKU load balancer, and configure backups to a Recovery Services Vault in the East US region.
  3. C
    Deploy VM1 in Availability Zone 1, select a VM size that supports Ultra Disk, enable Ultra Disk compatibility, associate the VM with a Basic SKU load balancer, and configure backups to a Recovery Services Vault in the East US region.
  4. D
    Deploy VM1 in Availability Zone 1, select a VM size that supports Ultra Disk, enable Ultra Disk compatibility, associate the VM with a Standard SKU load balancer, and configure backups to a Recovery Services Vault in the West US region.

Answer

Deploy VM1 in Availability Zone 1, select a VM size that supports Ultra Disk, enable Ultra Disk compatibility, associate the VM with a Standard SKU load balancer, and configure backups to a Recovery Services Vault in the East US region.
The configuration deploying the virtual machine to Availability Zone 1, enabling Ultra Disk compatibility with a supported VM size, using a Standard SKU load balancer, and choosing a Recovery Services Vault in the East US region satisfies all requirements. Availability Zones protect against datacenter-wide failures, and Ultra Disks are required for the sub-millisecond latency and high IOPS workload. A Standard SKU load balancer is needed to support virtual machines in Availability Zones, and the Recovery Services Vault must be in the same region (East US) as the VM.

Step-by-Step Solution

1
Select the high availability option that protects against datacenter-wide failures.
Availability Zones (specifically Availability Zone 1) must be selected, as Availability Sets only protect against hardware failures within a single datacenter.
Protecting against datacenter-wide outages requires physically separate zones within an Azure region.
2
Configure the VM size and settings to support Ultra Disk storage.
Choose a VM size that supports Ultra Disk, and enable the 'Ultra Disk compatibility' setting during the VM deployment process.
Ultra Disks are required to meet the 80,000 IOPS and sub-millisecond latency requirement, but they require explicit compatibility enablement on the host VM.
3
Select the correct load balancer SKU to support the zonal VM.
Associate the VM with a Standard SKU load balancer.
Basic SKU load balancers do not support zonal virtual machines in their backend pools.
4
Select the correct region for the Recovery Services Vault.
Configure backups to a Recovery Services Vault located in the East US region.
Azure Backup requires the Recovery Services Vault to be in the same geographic region as the virtual machine being backed up.

Key Concept

Deploying and configuring virtual machines with specific disk performance (Ultra Disk), high availability (Availability Zones), load balancing SKU compatibility, and region-matched backup resources.
