I’ve always liked and recommended Microsoft Fundamentals exams. Last year, before this new generation was created, I went back to gap fill my Office 365 MCSA with the Cloud, Mobility and Security Fundamental MTA’s (98-367, 368, 369). And even though these new generation MCF’s - like MTA’s - are optional (they don’t count towards the associate workloads) I don’t personally believe in bypassing them. No shortcuts. But Others may disagree. I respect that.
