Difficulty: HardCreate and Configure Virtual Machines

An administrator is planning the deployment of a new virtual machine named VM-Prod1 in the East US region. The virtual machine will host a database workload. The deployment must satisfy the following requirements:
- Use Ultra Disk storage for the database log files.
- Provide high availability with infrastructure protection against datacenter-wide failures.
- Position the virtual machine backend pool behind a public-facing load balancer.
- Configure daily backups for VM-Prod1.

You currently have an active Recovery Services Vault named RSV1 located in the West US region and a Public Load Balancer named LB1 configured with the Basic SKU.

Which configuration must you select to meet all deployment requirements?

  1. A
    Deploy VM-Prod1 in an Availability Set in the East US region, use the existing Basic SKU LB1, and create a new Recovery Services Vault in the East US region.
  2. Deploy VM-Prod1 in an Availability Zone in the East US region, deploy a Standard SKU Load Balancer, and create a new Recovery Services Vault in the East US region.Answer
  3. C
    Deploy VM-Prod1 in an Availability Zone in the East US region, use the existing Basic SKU LB1, and create a new Recovery Services Vault in the East US region.
  4. D
    Deploy VM-Prod1 in an Availability Zone in the East US region, deploy a Standard SKU Load Balancer, and use the existing RSV1 in the West US region.

Answer

Deploy the virtual machine in an Availability Zone in the East US region, deploy a Standard SKU Load Balancer, and create a new Recovery Services Vault in the East US region.
Deploying the virtual machine to an Availability Zone is necessary to support Ultra Disk storage and provide infrastructure redundancy that protects against datacenter-wide failures. Furthermore, a Standard Load Balancer is required to route traffic to resources deployed in Availability Zones, as Basic Load Balancers do not support zonal instances. Finally, virtual machine backups using a Recovery Services Vault must occur within the same target region as the source virtual machine, requiring a new vault in the East US region.

Step-by-Step Solution

1
Determine the high availability and storage requirements.
Ultra Disk storage and protection against datacenter-wide failures dictate that the virtual machine must be deployed in an Availability Zone rather than an Availability Set.
Ultra Disks are zonal resources, and Availability Zones provide the physical isolation needed for datacenter-wide failure protection.
2
Evaluate the Load Balancer compatibility.
A Standard SKU Load Balancer is required to support the backend pool members located in specific Availability Zones.
Basic SKU Load Balancers do not support zone-specific virtual machines.
3
Evaluate the backup vault regional constraint.
A new Recovery Services Vault must be created in the East US region.
Azure Backup requires the Recovery Services Vault to reside in the same region as the virtual machine being backed up.

Key Concept

Azure VM infrastructure redundancy, storage compatibility (Ultra Disk), load balancer SKU limitations, and backup regional constraints.
