Most wrong answers on Security+ and Network+ aren't knowledge gaps. You read the objective, you watched the video, you could explain the term to a coworker. Then the exam hands you a scenario, two of the five answers look correct, and you pick the wrong one. That's not "I didn't study." That's "I couldn't tell which of these two similar things the question is describing."
Those are different skills. Knowing what tokenization is and being able to separate it from masking under time pressure are not the same muscle. The exam is built almost entirely on the second one. It rarely asks "define X." It asks "a company needs Y — which control fits," and the trap is a near-neighbor concept that's correct in isolation but wrong for the scenario.
This is why re-reading notes and grinding more questions past a certain point stops helping. Both reinforce recall. Neither trains discrimination — the ability to name the one feature that splits two look-alikes. Below are the pairs that trip people up the most, with the splitting feature for each. Once you can name the discriminator, the question gets easy.
WPA2 vs WPA3
Everyone knows WPA3 is newer and "more secure." The exam doesn't care that you know it's newer. It asks what WPA3 actually added, and that's where people stall.
