Network+ N10-009 Exam Format: Questions, Time, PBQs, and Passing Score Explained

Knowing exactly how the exam is built lets you walk in with a plan instead of nerves. This article covers how the CompTIA Network+ N10-009 exam is structured — the question count, the time, the performance-based questions, the scoring, and the one skill (subnetting) that quietly influences your whole result.

For the wider certification picture, start with the complete Network+ guide. This piece zooms in on format.

The core numbers

Here's the structure of the current N10-009 (V9) exam:

• Up to 90 questions. Ninety is the maximum; your exam may have slightly fewer, and some items may be unscored trial questions.
• 90 minutes. That's roughly one minute per question on average — tight, which is why speed on subnetting and recall matters.
• Multiple-choice and performance-based questions (PBQs). Multiple-choice includes single- and multiple-response items and drag-and-drop; PBQs are interactive tasks in a simulated environment.
• Passing score of 720 on a scale from 100 to 900.

Performance-based questions

PBQs are what make Network+ feel practical. Instead of recognizing an answer, you perform a task — configuring a device, matching or ordering steps, interpreting output, or troubleshooting in a simulated environment. They typically appear near the start of the exam, and you can flag them to return to later.

The smart strategy is to glance at each PBQ and, if it looks time-consuming, flag it and move on to the multiple-choice questions, which you can usually answer faster. Bank the quicker points first, then come back to the heavy PBQs with your remaining time. Candidates who sink fifteen minutes into one early PBQ and then rush the rest of the exam are the ones who run out of clock.

Because PBQs reward hands-on skill, you can't cram them. Our PBQ and hands-on prep guide covers how to rehearse them.

Why subnetting is the hidden difficulty

Here's the thing every Network+ veteran will tell you: subnetting appears throughout the exam, not just in one domain. You need to calculate subnet masks, network and broadcast addresses, and usable host ranges quickly and accurately. With only about a minute per question, slow subnetting drains time you need elsewhere.

The fix is repetition until it's automatic. If you can subnet in your head or on scratch paper in seconds, you free up mental bandwidth for the scenario questions. Make subnetting drills a daily habit, not a one-time review.

How the scaled score works

The 720 passing mark sits on a 100–900 scale and is weighted by question difficulty, so it isn't a clean percentage. Roughly speaking it corresponds to answering a large majority of questions correctly, but don't try to game "how many can I miss." Aim for competence across all five domains — and since Troubleshooting (24%) and Networking Concepts (23%) are the two heaviest, weakness in either is hard to offset. The full weighting is in the domains breakdown.

Pacing strategy for test day

A dependable approach:

1. Triage the PBQs first. Do the quick ones; flag the slow ones and move on.
2. Work the multiple-choice steadily. About a minute each. Flag anything uncertain and keep moving rather than stalling.
3. Return to flagged items — PBQs and marked questions — with your remaining time.
4. Leave nothing blank. There's no penalty for a wrong answer, so always commit to your best guess.

Rehearsing under a 90-minute timer is what makes this routine. If your first full-length practice run overshoots, that's information to act on, not a verdict.

Retake rules

If you don't pass, there's no waiting period before your second attempt. After a second failure, a 14-day wait applies between subsequent attempts, and each attempt requires its own fee.

Where format prep fits

Format familiarity is the finishing layer over real skill. Learn the objectives, drill subnetting daily, build hands-on reps, then rehearse full-length timed sessions. Our study plan sequences all of it.

FAQ

Will I get exactly 90 questions? Ninety is the maximum. Your specific exam may have fewer, and some questions may be unscored trial items.

How much time per question? About one minute on average. PBQs take longer, so triage them and move quickly through multiple-choice.

Do PBQs come first? They typically appear near the start, and you can flag them to return later — which is the recommended strategy.

How important is subnetting? Very. Subnetting questions appear throughout the exam, and speed matters because time is tight. Drill it until it's automatic.

Is there a penalty for guessing? No. Always answer every question, even if it's a best guess.

What happens if I fail? You can retake immediately for a second attempt. After a second failure, a 14-day wait applies between attempts, each with its own fee.
