Failed DBA exam twice — what actually helped me pass on attempt three? — Forums

So I've been on this journey for about eight months now and I'm honestly embarrassed it took me this long. Failed in September, failed again in December, and I finally passed last month with a 78. I'm not some genius — I work as a junior database admin and figured the cert would be basically review. Wrong. The exam goes way deeper on query optimization and indexing strategies than anything I dealt with day-to-day.

What actually moved the needle for me was grinding through a solid DBA practice test bank instead of just re-reading the official docs. I was doing maybe 20-30 questions a night for about six weeks. The study guide I was using before wasn't bad, but it was too broad — I needed something that forced me to apply concepts under timed conditions, not just recognize definitions.

For anyone who's failed once or twice, don't give up. The exam is absolutely passable. I'd love to hear what exam tips worked for other people, especially around the performance tuning and backup/recovery sections, which killed me on attempt two.

Congrats on passing! Performance tuning wrecked me too on my first attempt. What helped me was focusing less on memorizing syntax and more on understanding WHY the optimizer makes certain choices. Once that clicked, those scenario questions got way easier. Also — I'd highly recommend timing yourself on practice tests from the start. I wasn't doing that and it cost me probably 12-15 questions on exam day just from running out of time.

Can I ask which practice test bank you ended up using? I'm about six weeks out from my scheduled date and I've been going back and forth between two different study guides. One is really comprehensive but honestly kind of dry and I'm struggling to stay focused. I've been averaging around 65% on my practice runs and I'm not sure if that's good enough or if I need to push the date back.

65% on practice tests with six weeks left is totally workable — I was at 61% three weeks out and passed with a 74. Just stay consistent and really dig into every wrong answer, not just the right one. Understanding why the wrong choices are wrong is half the battle on this exam.
