Question 1IPv4 addressing
Which CIDR prefix is the same as the mask 255.255.240.0?
The Network+ passing score
You need 720 on a scale of 100 to 900. It is a scaled score, not a percentage of questions right, and CompTIA does not publish how raw answers convert to it.
| Exam | N10-009 (V9) |
|---|---|
| Questions | A maximum of 90, multiple choice and performance-based |
| Time | 90 minutes |
| Passing score | 720 on a scale of 100 to 900 |
Why 720 is not 80%
A scaled score puts every version of the exam on the same 100 to 900 range. Because CompTIA does not publish the conversion, 720 cannot be turned into a number of questions. Any calculator that claims to do so is guessing.
How to judge your readiness
- Take full timed practice exams: 90 questions in 90 minutes, across all five domains by their weights.
- Look at your weakest domain, not only the total. Troubleshooting (24%) and networking concepts (23%) carry the most marks.
- Answer every question. A blank cannot score.
Try 3 questions
Question 2Disaster recovery
Over a year, a firewall cluster had three outages that took 2 hours, 4 hours and 6 hours to repair. What is the mean time to repair?
Question 3Network services issues
A workstation's ipconfig shows: IPv4 Address: 192.168.5.40 Subnet Mask: 255.255.255.0 Default Gateway: 192.168.5.254 The router's LAN interface is 192.168.5.1, and no device uses 192.168.5.254. Which symptom will the user see?

Questions people ask
What percentage do you need to pass Network+?
CompTIA sets the pass at 720 on a scale of 100 to 900 and does not publish a percentage or a raw-score conversion.
How many questions do I need right to pass?
Nobody outside CompTIA can say: the conversion from answers to the 100 to 900 scale is not published.
Is the Network+ passing score the same as Security+?
No. Network+ N10-009 needs 720; Security+ needs 750. Both use the 100 to 900 scale.
