Selected Answer: BD

Look at the SIP Dial-in Flow to VMN (scenario1), it eludes to CUCM making decisions. https://www.ciscolive.com/c/dam/r/ciscolive/apjc/docs/2019/pdf/BRKCOL-2073.pdf Local reachable VMN resources are tried first, in order of lowest SRT delay. When all local resources are exhausted, the participant connects to the cloud. Cert Guide pg 426

D is correct because: In Unified CM, each SIP trunk can support up to 16 Video Mesh destinations (IP addresses).
