CompTIA Network+ certifies core networking knowledge: the OSI and TCP/IP layers, TCP vs UDP and the handshake, IP addressing and subnets (CIDR), NAT and routing, DNS resolution, the TLS handshake, and the HTTP/1.1 vs HTTP/2 vs HTTP/3 internals — plus the network-security essentials: access control, authentication, and the TLS/PKI trust chain.
Keentune builds that conceptual foundation with questions that meet you at your level and get harder as you improve — a focused complement to the official objectives and hands-on labs. Use the sections below to firm up the concepts behind the exam.

Yes. You can start practicing immediately — no signup, no payment. Create a free account only when you want to save your level, streak, and progress across devices.
What does the CompTIA Network+ practice cover?
It’s organized around the CompTIA Network+’s sections — Networking and Network security — with adaptive questions for the skills behind each one. You practice the underlying abilities the CompTIA Network+ rewards rather than memorizing a fixed question set.
How does the adaptive difficulty work?
Every question is chosen near your current level in that skill. Answer well and it gets harder; miss and it eases back — so practice stays at the “optimal challenge” point where you improve fastest, and your level tracks your real progress.
Is this the official CompTIA Network+, or a practice test?
Neither. Keentune is independent skill practice ALIGNED to the CompTIA Network+’s skill areas — not official material and not a replica of the exact test format. Keentune is independent study practice, not affiliated with CompTIA. It never guarantees a pass. CompTIA and Network+ are trademarks of CompTIA, used here for identification only.
