Hi @Lester Pollard
MS-700 (Managing Microsoft Teams) leads to the Teams Administrator Certification - it focuses on:
- Managing and governing the teams, chats and meetings through policies;
- The migration/upgrade from Skype for Business Server to Teams through different co-existence models;
- Phones System and Audio Conferencing aspects and;
- The overall architecture of Teams and the multiple areas involved.
MS-300 and MS-301 exams (Deploying Microsoft 365 Teamwork and SharePoint Server Hybrid) lead to the Teamwork Administrator Certification, Microsoft Teams is only one component of this certification - the majority of this certification is dedicated to SharePoint Online, SharePoint Hybrid and the connections to OneDrive and Teams.
Since the Teamwork Administrator Certification and the respective MS-30x exams are being retired August 31, 2020 - I would wait until Microsoft officially announce whether/what will replace this Certification and the required exams.
Regards
Andrew
