Cisco CCNA 200-301 · exam topics v1.1
Free CCNA study guide, plus labs in your browser
The guide covers all 53 objectives on Cisco's exam topics list, numbered the same way. Each lesson explains the topic, shows a working IOS config, and points out what tends to come up on the exam.
The six exam domains
Domains 1 to 3 make up 65% of the exam, so that's where most of your time should go: subnetting, VLANs and trunking, spanning tree, the routing table, and OSPF.

Network Fundamentals
20%Devices, topologies, cabling, TCP/UDP, IPv4 and IPv6 addressing and subnetting, wireless and virtualization basics, switching concepts
- 2
Network Access
20%VLANs, trunking, CDP/LLDP, EtherChannel, Spanning Tree, wireless architectures and the WLC
- 3
IP Connectivity
25%Routing tables, how routers choose routes, static routing, single-area OSPFv2, first hop redundancy
- 4
IP Services
10%NAT, NTP, DHCP, DNS, SNMP, syslog, QoS, SSH, TFTP/FTP
- 5
Security Fundamentals
15%Threats, device hardening, VPNs, ACLs, Layer 2 security, AAA, wireless security
- 6
Automation and Programmability
10%SDN, controllers, APIs, AI/ML in networking, Ansible/Terraform, JSON
Hands-on labs
48 labs with routers, switches and PCs that run in your browser. You type real IOS commands to build a network or fix a broken one, and the lab checks your work task by task. You don't need Packet Tracer or anything else installed. The Domain 1 lab is free.
How the guide is set up
Same numbering as the exam topics
Sections are numbered 1.1 through 6.7, sub-objectives included, exactly like Cisco's exam topics list. That makes it easy to see what you've covered.
Configs you can type in
Every config example is a real IOS session, followed by the show commands that verify it. Type it into a lab or Packet Tracer and compare the output.
Tips, facts and common mistakes
Key Facts boxes collect the numbers to memorize. Exam Tips show how a topic is usually asked. Common Mistakes cover what people tend to get wrong, and Beginner Notes explain terms you might not know yet.
Practice questions for every domain
Each domain ends with 15 exam-style questions. Every answer has an explanation, including why the other options are wrong.
Reference
Subnetting cheat sheet
Powers of two, the full /8 to /32 prefix table, the magic number method, and worked problems.
Appendix BCommand reference
Every IOS command in the guide, grouped by task, with the show command that verifies it.
Appendix CNumbers to memorize
Ports, administrative distances, STP and OSPF timers, and DSCP values. Good for a last review.
Who made this
I'm Luis, a network engineer in California, and I run Learn CCNA on my own. The labs run on a network emulator I built. Before a command goes in, I run it on real Cisco IOSv and vIOS-L2 in my own EVE-NG lab and match what they print. If I haven't captured something yet, the emulator tells you instead of guessing.
