Why use an IT Quiz?

Staying sharp on foundational IT knowledge — DNS, HTTP status codes, Linux permissions, database theory — is what separates engineers who can debug quickly from those who have to look everything up. This quiz covers six core categories at three difficulty levels, shuffles questions and answer order on every run, and shows explanations after each answer so you learn as you go. Pair it with the Linux commands reference, port reference, and HTTP status code reference.
