About these questions

How we check these questions

  1. Written from the source. Every question is our own wording of a fact in the CompTIA Network+ N10-009 Certification Exam Objectives, never copied from a real exam.
  2. Checked against its section. Each answer names the section it comes from, and the answer is checked against that text. Anything we cannot confirm there is not published.
  3. Machine checks on the whole bank. Validators look for duplicates, missing explanations and missing sources.
  4. Re-checked on changes. When CompTIA revises the source, the bank is audited again. Last update: October 7, 2026.

Questions written from the published CompTIA Network+ N10-009 exam objectives; not official or recalled CompTIA items. Spot an error? Email [email protected] with the question; we check it against the source and fix confirmed errors. Editorial policy.

CompTIA Network+ (N10-009) FAQ

N10-009, the current Network+ exam. CompTIA states a maximum of 90 questions, a mix of multiple-choice and performance-based, in 90 minutes.

720 on a scale of 100–900. Because it is scaled, a practice percentage is a study signal rather than a predicted exam score.

Yes. Open the exam simulator and sit a timed mock exam of 20 questions built from the free questions, once, with no signup. Unlocking the exam adds full-length runs of 90 questions in 90 minutes (the published time limit), as many as you like, each a new draw from the whole bank.

It splits the questions across the exam's areas using the weights CompTIA publishes, then picks questions inside each area, favouring ones you missed before and never repeating one within a run. A retake is a new draw, so you will meet different questions. It is a practice mock exam, not an official replica of the real exam.
