I achieved the Microsoft 365 Teamwork Administrator Associate qualification by taking the transition exam MS-302 which is only available for people who have achieved Exam 70-339 – SharePoint 2016 and the transition exam was only available to take until September 30th 2019 then it is was retired. The route now to get this qualification is to pass two exams MS-300 and MS-301.
Microsoft 365 Teamwork Administrators configure, deploy, and manage Office 365 workloads that focus on efficient and effective collaboration, such as SharePoint (online, on-premises, and hybrid), OneDrive, and Teams.
Below are some study links I have found for my colleagues as part of coaching them to gain this qualification:
MS-300 (Deploying Microsoft 365 Teamwork (https://www.microsoft.com/en-us/learning/exam-ms-300.aspx)
MS-301 (Deploying SharePoint Server Hybrid (https://www.microsoft.com/en-us/learning/exam-ms-301.aspx)
As with all my Microsoft 365 exams I recommend you get an Office 365 trial then try out creating a few test users and administering them from all the different admin centres of Microsoft 365.
Also practice any areas which you may not be familiar of when you are doing your exam reading so you gain familiarity. Microsoft are soon going to be bringing in performance testing so you will be given a scenario then in the exam it will boot into a virtual machine and you’ll have an actual practical assessment.
I do all my exams online so booked from the Official Microsoft page for the exam I wanted to take and then specified I wanted to do it from home or office.
Key Advice : Get the exam booked and on your schedule to force you to get into study mode ?
