I’ve taken eleven technical certification exams in the past 4 months without failing one.
The last one I passed — the RHCE — has a first-time failure rate in the 50% range. Here’s a list of the progressive and the cumulative certifications I’ve earned.
Microsoft Certified Professional–>Microsoft Certified Solutions Associate–>Microsoft Certified Solutions Expert (Server Infrastructure 2012). (four exams total)
Cisco Certified Networking Associate(R&S)–>Cisco Certified Networking Professional (R&S). (four exams total)
VMWare Certified Professional. (one exam)
Red Hat Certified System Administrator–>Red Hat Certified Engineer. (two exams total, all practical on live system)
I think I’ll stop now. I might go for the PMP next, in a few months. Or maybe one of the security certifications after I recover for a bit.
