Assigning Users to Session Hosts

Correct Answer: D

Depth-first load balancing in Azure virtual desktop consolidates new connections to the session host with the greatest number of users until the max session limit is reached.Load balancing options are not available with personal host pools.Option A is incorrect.

Load balancing options are not available with personal host pools.

Option B is incorrect.

The breadth-first load balancing option will distribute new user sessions across all available session hosts in the host pool.

So, it is the incorrect option.

Option C is incorrect.

Load balancing options are not available with personal host pools.

Option D is correct.

Depth-first load balancing in Azure virtual desktop consolidates new connections to the session host with the most number of users until the max session limit is reached.

Option E is incorrect.

Host pools are of two types: Personal or Pooled.

There is nothing like a public host pool.

So this option is invalid.

Option F is incorrect.

Host pools are of two types: Personal or Pooled.

There is nothing like a public host pool.

So this option is invalid.

In Azure Virtual Desktop, the concept of host pools and session hosts is used to deploy and manage virtual desktops for users. A host pool is a collection of session hosts that are used to host user sessions. Each session host is capable of hosting multiple user sessions, depending on its configuration.

When assigning users to session hosts, there are two primary algorithms that can be used: breadth-first and depth-first.

• Breadth-first: This algorithm assigns users to the session hosts in a round-robin fashion. That is, the first user is assigned to the first session host, the second user is assigned to the second session host, and so on, until all session hosts have an equal number of users. Once all session hosts have an equal number of users, the algorithm starts again from the first session host.

• Depth-first: This algorithm assigns users to the session hosts in a sequential fashion. That is, the first user is assigned to the first session host, the second user is assigned to the second session host, and so on, until the last session host has been assigned a user. Once the last session host has been assigned a user, the algorithm starts again from the first session host.

There are also two types of host pools that can be used: personal and pooled.

• Personal host pool: This type of host pool is used for dedicated virtual desktops. Each user is assigned a dedicated virtual desktop, which is hosted on a session host.

• Pooled host pool: This type of host pool is used for shared virtual desktops. Multiple users are assigned to a single session host, and each user is given their own session within that host.

Based on the above information, we can eliminate options E and F, as they both refer to public host pools, which are not mentioned in the scenario. Option C can also be eliminated, as breadth-first is not the best algorithm to use in a personal host pool.

Option A (depth-first in a personal host pool) assigns each user to their own dedicated virtual desktop on a session host, which means that the number of users assigned to each session host will be equal to the number of session hosts in the host pool. Therefore, this option will not assign the largest number of users to the smallest number of session hosts.

Option B (breadth-first in a pooled host pool) assigns users to session hosts in a round-robin fashion, which means that the number of users assigned to each session host will be roughly equal. This is the best option for assigning the largest number of users to the smallest number of session hosts, as it ensures that all session hosts are used evenly.

Therefore, the correct answer is option B: Breadth-first in a pooled host pool.
