What should you include in the solution?

You have a Windows Virtual Desktop host pool that runs Windows 10 Enterprise multi-session.

You need to configure automatic scaling of the host pool to meet the following requirements:

Distribute new user sessions across all running session hosts.

Automatically start a new session host when concurrent user sessions exceed 30 users per host.

What should you include in the solution?
A . an Azure Automation account and the depth-first load balancing algorithm
B . an Azure Automation account and the breadth-first load balancing algorithm
C . an Azure load balancer and the breadth-first load balancing algorithm
D . an Azure load balancer and the depth-first load balancing algorithm

Answer: B

Explanation:

For the scenario described, you need a solution that automatically scales out the number of session hosts based on the number of concurrent user sessions. Azure Virtual Desktop (AVD) supports two types of load-balancing algorithms:

Depth-first: This algorithm fills up one session host to its maximum capacity before moving on to the next one. This approach doesn’t distribute new sessions evenly and therefore doesn’t meet the requirement to distribute new user sessions across all running session hosts.

Breadth-first: This algorithm distributes new sessions across all available session hosts in the host pool. This approach meets the requirement to distribute new user sessions across all running session hosts.

Since you need to automatically start a new session host when concurrent user sessions exceed a certain number per host, Azure Automation can be used to automate this scaling process based on a predefined threshold of concurrent sessions.

Therefore, the solution should include:

B. an Azure Automation account and the breadth-first load balancing algorithm

This combination will ensure that new user sessions are distributed across all running session hosts and that new session hosts are automatically started when the threshold of 30 concurrent user sessions per host is reached.
