How to Use This Guide
This guide is built directly from Cisco’s official CCNA 200-301 v1.1 exam topics document (the “blueprint”). Every numbered objective in that blueprint — 1.1 through 6.7, including every lettered sub-objective — has its own section here, using the same numbering, so you can always tell exactly which exam topic you are studying and check your progress against the official list.
It is written for someone starting from zero. Every term is defined the first time it is used, and each objective follows the same pattern: a plain-English explanation of what the thing is and why it exists, the precise technical details the exam tests, a realistic configuration and verification example on Cisco IOS, and callouts that flag what to memorize and what people commonly get wrong.
About the exam
| Item | Detail |
|---|---|
| Exam number | 200-301 CCNA (topics version 1.1) |

| Passing score | Not published; typically in the 800–850 range on a 300–1000 scale |
| Prerequisites | None |
| Validity | 3 years |
Cisco does not allow you to go back to earlier questions once you move on, so answer each question before advancing. There is no penalty for guessing — never leave a question blank.
The six domains and how much they count
| Domain | Weight | What it covers |
|---|---|---|
| 1.0 Network Fundamentals | 20% | Devices, topologies, cabling, TCP/UDP, IPv4 and IPv6 addressing and subnetting, wireless and virtualization basics, switching concepts |
| 2.0 Network Access | 20% | VLANs, trunking, CDP/LLDP, EtherChannel, Spanning Tree, wireless architectures and the WLC |
| 3.0 IP Connectivity | 25% | Routing tables, how routers choose routes, static routing, single-area OSPFv2, first hop redundancy |
| 4.0 IP Services | 10% | NAT, NTP, DHCP, DNS, SNMP, syslog, QoS, SSH, TFTP/FTP |
| 5.0 Security Fundamentals | 15% | Threats, device hardening, VPNs, ACLs, Layer 2 security, AAA, wireless security |
| 6.0 Automation and Programmability | 10% | SDN, controllers, APIs, AI/ML in networking, Ansible/Terraform, JSON |
Notice that Domains 1, 2, and 3 together are 65% of the exam. Subnetting (1.6), VLANs and trunking (2.1–2.2), Spanning Tree (2.5), the routing table (3.1–3.2), and OSPF (3.4) are the heart of the CCNA. Give them the most time.
Callouts used in this guide
Suggested study plan
A realistic self-study schedule for a beginner is 8–12 weeks at roughly one to two hours per day. A workable split is: weeks 1–3 on Domain 1 (spend at least a full week on subnetting until you can do any problem in under a minute), weeks 4–5 on Domain 2, weeks 6–7 on Domain 3, week 8 on Domains 4 and 5, week 9 on Domain 6, and the remaining time on review, the practice questions at the end of every domain, and hands-on labs.
Hands-on practice matters. Cisco Packet Tracer is free and is enough to practice every configuration in this guide. Type every command shown here yourself, then run the verification commands and compare the output.
Practice questions and answer keys
Each domain ends with 15 exam-style practice questions. The answer keys, with explanations, are collected together after Domain 6. Attempt the questions before looking, and for every question you miss, go back and reread the section rather than just memorizing the answer.
Conventions
Cisco IOS commands appear in fixed-width text, with the prompt showing the mode you must
be in: Router# is privileged EXEC mode, Router(config)# is global configuration
mode, and Router(config-if)# is interface configuration mode. Lines beginning with
! inside configurations are comments explaining the step and are not typed. Sample
show output is representative; exact wording varies slightly between IOS versions.
