I came from traditional PBX work and Teams Phone felt like a different planet at first. The practice questions here - especially around Operator Connect and emergency calling - gave me a real map of the exam domains. Passed on my second attempt and felt genuinely ready.
Direct Routing finally made sense. Cleared MS-721 first attempt.
Teams Phone licensing questions finally clicked for me.
The SBC configuration and Direct Routing questions exposed gaps I didn't know I had - glad I found them here before the real exam.
