Question
Your company has a main office and two branch offices. Each office connects directly to the internet. The router in each branch office is configured as an endpoint for the following VPNs:
- A VPN connection to the main office
- A site-to-site VPN to Azure
The routers in each branch office have the Quality of Service (QoS) rules shown in the following table. Users in the branch office report slow responses and connection errors when they attempt to connect to Azure Virtual Desktop resources. You need to modify the QoS rules on the branch office routers to improve Azure Virtual Desktop performance. For which rule should you increase the bandwidth allocation?

Explanation
Azure Virtual Desktop performance relies heavily on RDP traffic, specifically UDP-based RDP Shortpath for media and session data (UDP port 3478 for STUN/TURN and UDP ports 49152–65535 for direct connections). In this scenario's QoS table, Rule3 corresponds to the traffic type used by AVD (UDP/RDP traffic toward Azure). Users experiencing slow responses and connection errors when connecting to AVD resources indicates that Rule3's bandwidth allocation is being throttled or is insufficient compared to other rules (e.g., VPN to main office traffic). Increasing the bandwidth allocation for Rule3 prioritizes AVD session traffic over less latency-sensitive traffic, resolving the performance issues.
