That's kind, thanks - I'm thinking of stopping at 100 certifications and letting a few I've kept up/renewed over the years expire.

When I first started, my favorite series were from Microsoft - excellent courses and I learned concepts. CompTIA is my least favorite, the exams don't seem to require deep knowledge.

Lately, the only exam I've taken where the prep really taught me a lot was Red Hat Certified Engineer which will help as automation works its way into everything
