Correct answer: The connection will fall back to TCP‑based reverse connect over port 443., Users will likely experience higher interactive latency and reduced multimedia quality..
Why this is the answer
When UDP egress is blocked, Azure Virtual Desktop (AVD) connections cannot utilize RDP Shortpath UDP, which is the preferred protocol for optimal performance. Instead, the connection will automatically fall back to TCP-based reverse connect over port 443. While this allows the session to establish, TCP is less efficient for real-time interactive traffic than UDP. This inefficiency typically results in higher interactive latency, making the user experience feel less responsive. Additionally, multimedia quality (like video and audio) will likely be reduced because TCP's retransmission mechanisms and overhead are not ideal for time-sensitive media streams. The session will not fail to establish because TCP fallback is designed for such scenarios. RDP Shortpath for managed networks requires UDP, so it won't be used. Teams media optimization is a separate feature and is not directly blocked by the lack of UDP for the core AVD connection.
