Zorluk: Çok zorCreate and Configure Virtual Machines

You are planning the deployment of a new virtual machine named AppVM-Prod to host a high-performance database. The workload has the following requirements:

* Storage: A 2 TB2\text{ TB} data disk that must deliver 60,00060,000 IOPS with sub-millisecond latency. The IOPS and throughput must be adjustable dynamically without virtual machine downtime.
* High Availability: Protection against entire datacenter outages within the primary hosting region.
* Backup: Daily backups must be configured and stored in an existing Recovery Services Vault named Vault-EastUS2, which is located in the East US 2 region.

Which configuration and deployment strategy should you select to meet these requirements?

  1. Deploy AppVM-Prod in an Availability Zone within the East US 2 region, enable Ultra SSD compatibility on the virtual machine during creation, attach an Ultra Disk as the data disk, and configure backups to Vault-EastUS2.Cevap
  2. B
    Deploy AppVM-Prod in an Availability Set within the East US 2 region, enable Ultra SSD compatibility on the virtual machine during creation, attach an Ultra Disk as the data disk, and configure backups to Vault-EastUS2.
  3. C
    Deploy AppVM-Prod in an Availability Zone within the East US region, enable Ultra SSD compatibility on the virtual machine during creation, attach an Ultra Disk as the data disk, and configure backups to Vault-EastUS2.
  4. D
    Deploy AppVM-Prod in an Availability Zone within the East US 2 region, enable Ultra SSD compatibility on the virtual machine during creation, attach an Ultra Disk as the data disk, and configure backups to Vault-EastUS2. To test backup restoration without disrupting the production workload, restore the virtual machine using the Replace existing restore type.

Cevap

Deploy the virtual machine in an Availability Zone within the East US 2 region, enable Ultra SSD compatibility during creation, attach an Ultra Disk as a data disk, and configure backups to the same-region Recovery Services Vault.
The correct strategy requires deploying the virtual machine in the East US 2 region to align with the existing Recovery Services Vault, as cross-region backups are not supported. Additionally, the virtual machine must be placed in an Availability Zone because Availability Zones protect against datacenter-wide failures and are a prerequisite for using Ultra Disks. The Ultra SSD compatibility capability must be enabled on the virtual machine during its initial creation to allow attaching an Ultra Disk, which provides the required 60,00060,000 IOPS and permits on-the-fly adjustment of performance settings without VM rebooting.

Adım Adım Çözüm

1
Identify the regional constraints for Azure Backup.
The virtual machine must be deployed in the East US 2 region because the existing Recovery Services Vault (Vault-EastUS2) is in East US 2, and Azure Backup requires the vault and virtual machine to reside in the same region.
To satisfy the backup requirement without deploying a new vault.
2
Determine the availability option and storage type.
Deploy the virtual machine in an Availability Zone to protect against datacenter-wide failures and to support Ultra Disk storage, which is only compatible with Availability Zones (not Availability Sets).
To satisfy the high availability and performance requirements.
3
Configure Ultra Disk capability.
Enable Ultra SSD compatibility on the virtual machine during the initial creation process, and attach a 2 TB2\text{ TB} Ultra Disk as a data disk.
Ultra SSD capability cannot be enabled on an existing virtual machine after deployment without recreation, and Ultra Disks allow dynamic adjustment of IOPS and throughput without downtime.
