About CertAce
CertAce is a small, independent practice platform for network certification exams, built and run by one network engineer in Romania.
Who builds it
I'm Adrian Neagu Metzak, a network engineer. I failed my first CCNA attempt with a score of 58%, then went back and passed. CertAce is the tool I wished I had the first time: practice questions where every option is explained, not just the right one, and an honest view of which exam domains still need work.
The full story, including what went wrong the first time: My CCNA journey.
