Network+ · CipherExam
Troubleshoot Network+ one layer at a time.
CipherExam explains every CompTIA Network+ (N10-009) answer through the Exam Lens — what OSI layer is this, and what is the systematic fix? Knowing the protocols isn't enough. Locating the symptom on the OSI model is. We drill that judgment; we do not simulate the PBQ interface.

Most Network+ candidates memorize ports, protocols, and topologies and still freeze on the troubleshooting items. The reason isn't a knowledge gap — it's a frame gap. N10-009 grades whether you can locate a fault on the OSI model and pick the systematic next step, not whether you can recite a definition. Question banks that just drill facts can't close that gap.
Three things compound for Network+
- Layer-first practice, classified by reasoning level. Questions are written so you have to locate the fault on the OSI model before choosing a fix, and all 106 carry a Bloom's cognitive level — 20 of them Analyze, which is where the real troubleshooting items live. Your results separate "I forgot the port number" from "I could not read the symptom".
- Exam Lens explanations. Every right and wrong answer is walked through the same lens — what OSI layer is this, and what is the systematic fix? — built against the OSI model and CompTIA's published N10-009 objectives, so you internalize layer-by-layer troubleshooting instead of guessing.
- 90-question Full Mock at exam pacing. 90 questions in 90 minutes — the same length CompTIA uses, drawn across the N10-009 domains as scenario-driven multiple choice.

Users on one access switch cannot reach the default gateway, but pings to that switch's management IP succeed from the same hosts. Where do you start troubleshooting?

Frequently asked
- Is this current for N10-009?
- Yes — the question library is built against CompTIA's published N10-009 exam objectives.
- Do you simulate Performance-Based Questions?
- No, and we would rather you knew before paying than after. The N10-009 bank is 106 scenario-driven multiple-choice questions. We do not simulate drag-and-drop, topology or CLI items. The engine for those formats exists; the content is not written. What we drill is the layer-first troubleshooting judgment those items grade. Use the free trial to judge that for yourself, and spend an hour in CompTIA's own exam demo before test day.
- What makes Network+ hard?
- The troubleshooting items. They mix multiple plausible fixes, and you have to locate the fault on the OSI model before acting. The Exam Lens names the layer first, then ranks the systematic fix.
- How many questions is the Full Mock?
- 90 questions in 90 minutes — the same length and pacing as CompTIA's exam. Scenario-driven multiple choice throughout; see the PBQ answer above.
- Can I cancel anytime?
- Yes. The 14-day trial never charges a card. Pro is month-to-month; cancel from your dashboard.
