Cisco CCNA (200-301) Roadmap

The gold standard for foundational network engineering. This roadmap breaks down the official Cisco exam objectives into six manageable domains, transitioning from pure theory to practical CLI configuration.

Official Exam Domains

1.0Weight: 20%

Network Fundamentals

Routers, switches, cabling types, TCP/UDP operations, IPv4/IPv6 addressing, and wireless principles.

Access Domain Modules View Command Library

2.0Weight: 20%

Network Access

VLANs, 802.1Q trunking, Spanning Tree Protocol (STP), EtherChannel, and WLC wireless architectures.

Access Domain Modules View Command Library

3.0Weight: 25%

IP Connectivity

Routing tables, static routes, Gateway of Last Resort, and Single-Area OSPFv2 configuration.

Access Domain Modules View Command Library

4.0Weight: 10%

IP Services

Inside Source NAT, DHCP relays (IP Helper), NTP, Syslog levels, and Quality of Service (QoS).

Access Domain Modules View Command Library

5.0Weight: 15%

Security Fundamentals

Access Control Lists (ACLs), AAA, Layer 2 mitigation (DHCP Snooping), and IPsec VPNs.

Access Domain Modules View Command Library

6.0Weight: 10%

Automation & Programmability

Controller-based networking, REST APIs, JSON data parsing, and Ansible/Puppet/Chef.

Recommended Lab Environments

Cisco Packet Tracer

The official simulation tool from Cisco. It is free via the Cisco Networking Academy. It simulates IOS CLI perfectly for CCNA-level routing (OSPF, Static) and switching (VLANs, STP).

Download via Skills For All

EVE-NG / Proxmox

For advanced users moving beyond simulation into emulation. Run actual Cisco IOS-XE images directly on your Proxmox server for real-world API testing, automation, and deep routing labs.

Exam Preparation Strategy

Boson ExSim-Max ($99/yr)

The undisputed gold standard for CCNA practice exams. It provides ~300 unique questions designed to be exactly 10-15% harder than the real CCNA. Highly Recommended. Do not waste money on the Boson NetSim or Subnetting tools; use free alternatives (Packet Tracer and subnetipv4.com) for those.

Unlimited RetakesNo Pass, No Pay Guarantee

Study Mode (The Real Value)

Gives immediate feedback after every question, alongside deep-dive, multi-paragraph explanations of why every answer is correct or incorrect, linking to official Cisco whitepapers. Treat this mode as an interactive textbook.

Simulation Mode

Mimics the actual Pearson VUE exam environment with strict timers. Use this strictly to test your pacing and readiness. Include Performance-Based Questions (PBQs) to ensure you can execute CLI commands under pressure.

Warning: The Memorization Trap. Because the question pool is finite, taking the same exam repeatedly will result in memorizing the answers, not mastering the concepts. Use the exams sparingly as diagnostics.
