You need to implement a disaster recovery plan for your domain controllers, which are utilized in your AVD deployment.
These domain controllers are currently deployed in the West Europe region.
Your design must provide a region failure solution.
Which of the following would you include in the plan?
Click on the arrows to vote for the correct answer
A. B. C. D.Correct Answer: C
Implementing additional domain controllers in the North Europe region can be included in the BCDR plan for Azure Virtual Desktop in case of a region failure.
This will ensure the availability of authentication services in a region failure scenario.
Option A is incorrect.
An S2S VPN will provide a connection to the on-premises network but it will not protect the domain controllers during the region failure.
Option B is incorrect.
Creating a point-to-site(P2S) VPN won't help in achieving the goal.
Option C is correct.
Implementing additional domain controllers in the North Europe region will ensure the availability of authentication services in a region failure scenario.
Option D is incorrect.
Availability zones protect your domain controllers from a datacenter or zone failure in a single region only.
They don't protect if the full region fails.

In this scenario, the goal is to implement a disaster recovery plan for domain controllers used in an Azure Virtual Desktop (AVD) deployment. The design must provide a region failure solution, which means that if the domain controllers deployed in the West Europe region fail, there should be a backup plan in place to ensure that the AVD deployment continues to function properly.
Let's look at each answer option in turn to see which would be the best choice for this scenario:
A. Create a site-to-site (S2S) VPN with your on-premises network A site-to-site VPN establishes a secure connection between your on-premises network and your Azure Virtual Network, allowing resources in both locations to communicate with each other. However, while this solution could be useful in many disaster recovery scenarios, it doesn't directly address the problem of domain controller failure in the West Europe region. Additionally, setting up a site-to-site VPN may require additional resources and configuration, which could complicate the disaster recovery plan.
B. Create a point-to-site (P2S) VPN with your on-premises network A point-to-site VPN is similar to a site-to-site VPN in that it establishes a secure connection between your on-premises network and your Azure Virtual Network. However, the main difference is that a point-to-site VPN is designed to allow individual devices to connect to the Azure Virtual Network from outside the network. Like the site-to-site VPN option, a point-to-site VPN doesn't directly address the problem of domain controller failure in the West Europe region, and it may require additional resources and configuration.
C. Implement two domain controllers in the North Europe region This option involves deploying two domain controllers in a different Azure region (North Europe) as a backup in case the domain controllers in the West Europe region fail. This solution provides a geographically separate backup for the domain controllers, which ensures that if a failure occurs in the West Europe region, there is a backup plan in place to keep the AVD deployment running smoothly. This is a good option for a disaster recovery plan, as it provides a region failure solution and is relatively straightforward to implement.
D. Implement two domain controllers in an availability zone An availability zone is a logical grouping of data centers in an Azure region that are designed to provide high availability and fault tolerance. Deploying domain controllers in an availability zone ensures that if one data center in the zone fails, the other data centers can continue to function and provide the necessary services. While this solution provides fault tolerance and high availability for the domain controllers, it doesn't directly address the problem of region failure. Additionally, implementing availability zones may require additional resources and configuration.
In summary, the best option for this scenario would be to implement two domain controllers in the North Europe region. This solution provides a geographically separate backup for the domain controllers, which ensures that if a failure occurs in the West Europe region, there is a backup plan in place to keep the AVD deployment running smoothly. It is also a relatively straightforward solution to implement, which makes it a good choice for a disaster recovery plan.
