I’m working through a set of Microsoft certifications that match my day-to-day work: MD-102 (Endpoint Administrator) first, then SC-300, AB-900 and AB-650. This is where I write down what each exam covers, which parts of the syllabus are worth the time, and what’s changed between versions, partly to make it stick and partly for anyone on the same path.
Posts that are also about running Microsoft 365 are filed under Microsoft 365 Admin as well.
