What learners say

Feedback from people who studied MS-721 on NerdExam.

The SBC configuration and Direct Routing questions exposed gaps I didn't know I had - glad I found them here before the real exam.

katya_uaSystems engineer

Teams Rooms and device management are easy to neglect when studying, but MS-721 does test them. Good to have focused practice questions there - that section nearly caught me off guard.

minji_krAV and collaboration admin

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.

fatima_krUC engineer

Coming from Skype for Business, the Teams Phone migration topics here mapped well to what MS-721 actually tests. Solid preparation resource.

brentmTelecom engineer

MS-721 goes deep on calling policies and dial plans, and the questions here reflect that. Not a magic shortcut, but a genuinely useful study tool.
