Question
You have an Azure Virtual Desktop deployment that contains a host pool named Pool1. Pool1 contains two session hosts named Host1 and Host2 and has the following settings:
- Host pool type: Pooled
- Load balancing algorithm: Breadth-first
You plan to implement Quality of Service (QoS) policies to manage RDP connections to Host1 and Host2. You need to ensure that the Azure Virtual Desktop deployment supports the QoS policies. What should you do?
Options
- AModify the Load balancing algorithm setting for Pool1.
- BEnable RDP Shortpath on Host1 and Host2.
- CAssign a scaling plan to Pool1.
- DApply an Azure tag on Host1 and Host2.

Explanation
QoS policies for RDP connections rely on DSCP (Differentiated Services Code Point) packet marking, which requires UDP-based transport. The default AVD reverse-connect transport uses TCP tunneling through the Azure gateway, which does not support DSCP markings. Enabling RDP Shortpath on Host1 and Host2 establishes a direct UDP connection between the client and the session host, making QoS policies effective. Changing the load balancing algorithm, assigning a scaling plan, or applying Azure tags do not affect the transport protocol and therefore do not enable QoS support.
