Study plan
A practical way to use this page
Start with a 25-question diagnostic to expose weak domains before taking a full 80-question simulation.
Prioritize Network Troubleshooting and Networking Concepts because they carry the highest weighting in this exam model.
Review explanations immediately after each attempt, then retest only the domains that caused missed questions.
Use strict timing once your accuracy stabilizes, then switch to full 90-minute exam practice before test day.

Frequently asked questions
These answers describe TechCertAI practice behavior. Vendor exam policies can change, so verify official exam details before scheduling.
How many questions are in the CompTIA Network+ N10-009 practice exam?
The full practice exam mode is modeled at 80 questions with a 90-minute time limit. The free diagnostic on this page uses 25 questions so you can identify weak domains faster.
Are the CompTIA Network+ questions weighted by exam domain?
Yes. Practice exams and diagnostics use the configured domain weights for N10-009, so heavier domains receive more questions than lower-weighted domains.
Do I need an account to try the diagnostic?
No. The diagnostic can be started from this page without creating an account. Creating an account unlocks saved progress, full quiz history, and full practice exam workflows.
Are these questions official vendor questions?
No. TechCertAI uses original practice questions built around the published exam objectives and reviewed question inventory. The questions are intended for study and readiness measurement, not as official exam content.
