Your company is evaluating Azure Virtual Desktop for three branch offices with different ISPs. You must measure expected user round‑trip latency to the Azure Virtual Desktop service and verify whether UDP can be used before choosing target Azure regions. Which two actions should you perform? (Select two answers.)

The Azure Virtual Desktop Experience Estimator is the correct tool for measuring user round-trip latency to the Azure Virtual Desktop service from specific locations. Running it from a workstation on each branch network during business hours provides realistic data, as network conditions can vary. The estimator also checks for UDP connectivity. To ensure the estimator can properly test UDP and TCP connectivity, the branch firewalls must allow outbound UDP 3478 (for STUN/TURN) and TCP 443 (for control plane communication) to the Azure Virtual Desktop service. Running the estimator on a session host VM in Azure would not measure user latency from the branch offices. Azure Network Watcher Connection Monitor is for general network connectivity monitoring, not specifically for AVD experience. Pinging public IP ranges is a basic network test and doesn't account for AVD-specific protocols or service endpoints.
