CompTIA Network+ Practice Questions (N10-009)

The voucher is $399, and that is the number most pages leave out

CompTIA lists the N10-009 exam voucher at $399. That is the bare exam and nothing else: one attempt, no retake, no training. If you fail, the next attempt is another $399, which is the single most expensive way to discover you were not ready.

CompTIA sells four bundles above that, all of which include a retake. Voucher plus Retake Assurance is $519. The Practice and Exam bundle with retake is $548. Learn and Exam with retake is $916. The Complete bundle with retake is $978. The $120 gap between the bare voucher and the retake bundle is the real decision: it is insurance against sitting again, priced at roughly a third of a fresh attempt.

This is worth doing the arithmetic on before you book. A bare voucher plus one failed attempt is $798. The retake bundle covers the same two attempts for $519. If you are not scoring consistently above the line in practice, the bundle is cheaper than optimism.

Passing is not the end: 30 CEUs and $150 over three years

Network+ is valid for three years. Renewing it takes 30 continuing education units, plus a CE fee of $150 across the cycle, billed at $50 a year. Note that 30 is the Network+ figure specifically. Security+ requires 50, and CompTIA has a stale FAQ page that still quotes 50 for Network+, so the number is easy to get wrong.

The lowest-friction route is CertMaster CE, a single activity that covers the whole 30 CEUs and takes most people 8 to 10 hours. You can also earn CEUs by collecting a higher CompTIA certification, completing relevant training, teaching, or documenting work experience.

Budget the full picture before you start: $399 to sit, then $150 and 30 CEUs every three years to keep it. Roughly $550 across the first cycle, assuming you pass first time.

How the two kinds of PBQ behave, and why it changes your timing

CompTIA runs two different performance-based question formats and they do not behave the same way under the clock. Simulations can be skipped and returned to later. Virtual environment questions cannot: once you are in one, you finish it there.

Both award partial credit, and CompTIA states plainly that there can be more than one valid way to solve a question. So a PBQ you half-finish is still worth something, and an unconventional but working solution is not automatically wrong.

The practical consequence is that the usual advice to skip every PBQ and come back is only half right. It works for simulations. On a virtual environment item you are committed, so the decision to engage has to be made before you start rather than after you have read it.

What the roles actually pay

CompTIA Career Explorer, CompTIA's own tool, lists median pay for the roles Network+ maps to: network support specialist at $68,000, junior network administrator at $90,000, systems administrator at $90,000, and junior systems engineer at $130,000.

Two caveats we will state rather than bury. These are role medians for people doing the job, not earnings attributable to holding the certification, and CompTIA does not date the figures. Anyone quoting you a precise "Network+ holders earn X" number is inventing the causal link.

Days 1-3: Take the free diagnostic and read your domain breakdown

Start with the free 25-question timed diagnostic. It scores you domain by domain so you can see exactly where you stand before spending a cent. Your two weakest domains become the focus of the plan.

Days 4-14: Study mode by domain, weakest first

Work through study mode one domain at a time, reading the rationale on every question including the ones you get right. Troubleshooting and Networking Concepts carry the most weight together, so do not leave them for last.

Days 15-24: Drill subnetting and PBQ-style items

Subnetting math and scenario items are the number-one candidate anxiety point. Work the addressing, VLAN and trunk logic, routing choice, wireless channel planning, and structured troubleshooting items until the reasoning is automatic.

Days 25-29: Full-length timed forms

Sit exam-mode forms under a strict 90-minute clock. Aim to consistently clear the pass approximation with time to spare, and review every miss by domain.

Day 30: Light review and rest

Review only your flagged and missed items from the last two forms. Do not cram new material the day before. Settled recall beats last-minute volume.
