CompTIA Network+ — Practice Questions and Mock Exam

CompTIA Network+ (N10-009) validates networking skills essential for designing, configuring, managing, and troubleshooting wired and wireless networks. It's vendor-neutral, covering concepts applicable to any network infrastructure.

Network+ is a critical stepping stone between A+ and advanced networking or security certifications. The N10-009 version emphasizes modern networking including software-defined networking, cloud connectivity, and network automation.

Network Troubleshooting is the single largest domain at 24%, followed closely by Networking Concepts at 23% and Network Implementation at 20%. Network Operations (19%) and Network Security (14%) round out the blueprint — Security is the smallest domain by a clear margin, but it still covers cryptographic basics, identity-based access controls, and attacks such as DDoS floods and ARP spoofing.

The exam weighs diagnosing a broken network almost as heavily as understanding how one is built: nearly half the questions sit in Troubleshooting and Implementation combined, both of which assume comfort with hands-on configuration and command-line tools rather than diagram-only familiarity. Security's low weight doesn't mean low difficulty — its questions are concentrated rather than spread thin, so gaps there are harder to compensate for elsewhere.

The exam draws up to 90 questions in 90 minutes, mixing multiple-choice, multiple-response, and performance-based questions (PBQs). PBQs put you inside a network scenario (configuring a device, reading a topology diagram, working through a connectivity problem) rather than asking you to recall a fact in isolation. The passing score is 720 on a scale of 100 to 900.

The COMPTIA-NET pool covers every exam domain and keeps growing with new questions. A mock exam asks 90 questions in one sitting, on the same 90-minute clock as the real thing.

How long you'll need depends on how much hands-on experience you bring. The rest is set by the vendor: how the exam is delivered, how soon you can retake it, and how long the credential stays valid.

Delivered at Pearson VUE testing centers or online with a proctor. The exam is available in English, German, Japanese, Portuguese, and Spanish. The certification is valid for three years and renews with 30 CEUs or by passing a higher-level CompTIA certification.

Subnetting speed matters more than subnetting knowledge: candidates who can explain CIDR notation but take two minutes per calculation run out of time before reaching the Network Troubleshooting domain, which carries the largest single weight at 24%. CompTIA's troubleshooting methodology has a specific step order, and exam questions expect that order even when a candidate would reasonably skip a step in the field. Wireless questions frequently hinge on distinguishing Wi-Fi 5, 6, and 6E by frequency band, channel width, and security protocol rather than by marketing name alone.
