Common questions
How many questions are on the Network+ exam?
A maximum of 90, multiple-choice and performance-based, in 90 minutes. Performance-based questions ask you to complete a task such as matching, ordering or configuring. CompTIA does not publish how many each exam has.
What score do you need to pass Network+?
720 on a scale of 100 to 900. CompTIA does not publish how raw answers convert to the scale. Our mock shows your points, a score for every domain and an estimated scaled score.
Is N10-009 the current Network+ exam?
Yes. N10-009 (V9) launched June 20, 2024. CompTIA usually retires an exam about three years after launch and estimates 2027; as of November 2026 its Network+ page announces no successor.
Should I take A+ before Network+?
CompTIA recommends A+ and 9 to 12 months of networking experience, but neither is required. If you are new to IT, A+ Core 1 covers the networking basics that Network+ builds on.
What is on the Network+ troubleshooting domain?
It is the largest domain at 24%: the troubleshooting methodology, cabling and interface errors, switching, addressing and routing faults, performance problems, and choosing the right tool or command, such as traceroute, dig, tcpdump or show interface.
How much does a Network+ retake cost?
The full exam price each time. There is no wait between a first and second attempt, and at least 14 calendar days before any later attempt.
Are these real Network+ exam questions?
No. Every question is original and written to the N10-009 exam objectives. CompTIA treats material that copies or closely resembles live exam questions as unauthorized.
How long does Network+ stay valid?
Three years. You renew by earning 30 continuing education units in that time, or by passing a newer exam or a higher-level CompTIA certification.
