› Common exam traps to study
Cybersecurity cert exams reuse the same 25 distractor patterns over and over — category confusion, RTO vs RPO, IDS vs IPS, MD5 vs SHA-256, and more. Once you can name the trap, you stop falling for it. Each archetype page covers what it is, the specific pairs candidates confuse, and how to avoid it.
