Difficulty: Very hardCreate and Configure Virtual Machines

An administrator is designing the deployment of a new virtual machine named `VM-Prod-DB` to host a database. The database requires storage that supports up to 90,00090,000 IOPS and sub-millisecond latency. Additionally, the database must be protected against datacenter-level outages. The administrator must also ensure that:

1. `VM-Prod-DB` is backed up daily to an existing Recovery Services Vault named `RSV-Prod-01` located in the East US 2 region.
2. `VM-Prod-DB` is placed in the backend pool of a public load balancer.

Which of the following configurations should the administrator select to deploy `VM-Prod-DB` successfully?

  1. Deploy the virtual machine in the East US 2 region, select an Availability Zone, enable Ultra Disk compatibility, and associate the virtual machine with a Standard SKU load balancer.Answer
  2. B
    Deploy the virtual machine in the East US region, select an Availability Zone, enable Ultra Disk compatibility, and associate the virtual machine with a Standard SKU load balancer.
  3. C
    Deploy the virtual machine in the East US 2 region, select an Availability Set, enable Ultra Disk compatibility, and associate the virtual machine with a Standard SKU load balancer.
  4. D
    Deploy the virtual machine in the East US 2 region, select an Availability Zone, enable Ultra Disk compatibility, and associate the virtual machine with a Basic SKU load balancer.

Answer

Deploy the virtual machine in the East US 2 region, select an Availability Zone, enable Ultra Disk compatibility, and associate the virtual machine with a Standard SKU load balancer.
To support the storage requirement of 90,00090,000 IOPS and sub-millisecond latency, Azure Ultra Disks must be used. Enabling Ultra Disk compatibility on a virtual machine requires selecting a supported size and deploying the VM in an Availability Zone (Availability Sets are not supported). Availability Zones also fulfill the requirement to protect the database against datacenter-level outages. Because the target Recovery Services Vault is located in the East US 2 region, the virtual machine must also be deployed in East US 2. Finally, a Standard SKU load balancer must be used because Basic SKU load balancers cannot have backend pools that contain virtual machines in Availability Zones.

Step-by-Step Solution

1
Determine the required region for the virtual machine based on backup constraints.
The virtual machine must be deployed in the East US 2 region.
Azure Recovery Services Vault backups are region-locked. Since the existing Recovery Services Vault is in East US 2, the virtual machine must reside in the same region to configure backup.
2
Identify the availability and disk requirements for the workload.
The virtual machine must use Availability Zones and have Ultra Disk compatibility enabled during creation.
Datacenter-level protection requires Availability Zones. Furthermore, hosting a database requiring 90,00090,000 IOPS and sub-millisecond latency requires Ultra Disks, which must be enabled at the virtual machine level during initial creation and are only supported when deploying in Availability Zones or as standalone VMs (Availability Sets are unsupported).
3
Verify load balancer SKU compatibility with the selected availability options.
The public load balancer must be a Standard SKU load balancer.
Basic SKU load balancers do not support backend pool members deployed in Availability Zones. Standard SKU is required to support zonal virtual machines.

Key Concept

Virtual machine deployment planning requiring alignment of storage performance (Ultra Disk compatibility and Availability Zone constraints), region dependencies (Recovery Services Vault constraints), and network SKU requirements (Load Balancer constraints).
