MS-100 Extras

MS-100 Overview & My Tips

MS-100 or Microsoft 365 Identity and Services is one of two exams that make up the Microsoft 365 Certified Enterprise Administrator Expert certification.  The certification also requires you to pass & hold a valid Microsoft 365 Associate level certification in addition to passing the MS-100 and MS-101.

The Microsoft 365 Certified: Enterprise Administrator Expert is the only Expert level certification for Microsoft 365.  Whilst the Associate certification in Microsoft 365 require Administrator level knowledge and skills, this is the next step up.  You could consider this the consultant level skillset.  You need an in-depth understanding of all features, the configuration options, pros/cons of the options PLUS hands on administration skills across the full set of Microsoft 365 workloads.  Tradition system administrator skills are also helpful as you should also understand DNS, Active Directory (on-prem), networking and on-prem server admin.  The on-prem skills and knowledge is needed to design and configure Microsoft 365 in Hybrid to work in harmony with existing environments as well as to understand requirements of organisations moving to the cloud.

That said, regular visitors to my blog will know that I consider myself a ‘born in the cloud’ admin and as such the traditional system administrator skills are my personal weak area.  Please don’t let that put you off going for this certification, if that also describes you.  You can use your Microsoft 365 knowledge to answer migration and hybrid questions and remember you don’t have to get all 1000 availalbe points to pass.

This exam focuses on identity & access (Azure AD) plus workload security & configuration whilst the MS-101 focuses on device management plus the security & compliance tools.
