Your company has created a personal host pool with Windows 7 VMs for supporting a legacy application. FSLogix was not utilized for the deployment and you have been asked to suggest a disaster recovery
The correct answer is C. Use site recovery services to replicate the session hosts to a secondary region. The most effective disaster recovery solution for personal Windows 7 session hosts without FSLogix, ensuring rapid business continuity, is to replicate the VMs using Azure Site Recovery.
Question
Your company has created a personal host pool with Windows 7 VMs for supporting a legacy application. FSLogix was not utilized for the deployment and you have been asked to suggest a disaster recovery solution. Cost is a consideration but not at the expense of a delay in business continuity. Which of the following is the best solution you will suggest?
Options
- AUse Azure Backup to backup the session host to a secondary region
- BBackup the profile containers and image to a secondary region
- CUse site recovery services to replicate the session hosts to a secondary region
- DNone of these. All these will lead to a delay in business continuity

Why each option
The most effective disaster recovery solution for personal Windows 7 session hosts without FSLogix, ensuring rapid business continuity, is to replicate the VMs using Azure Site Recovery.
Azure Backup is primarily for data protection and recovery, not for immediate failover of an entire running VM to ensure business continuity, as restoring from backup causes significant downtime.
Backing up only profile containers (which are not used here) and the image would still require manual deployment and configuration of new session hosts, leading to a substantial delay in business continuity.
Azure Site Recovery (ASR) provides near real-time replication of entire virtual machines to a secondary region, enabling a quick failover with minimal downtime and data loss. This directly addresses the requirement for business continuity with minimal delay, as ASR replicates the OS disk, data disks, and machine configuration, making it suitable for disaster recovery of personal session hosts.
This statement is incorrect because Azure Site Recovery (option C) specifically addresses the requirement for maintaining business continuity with minimal delay in a disaster scenario.
