What Is the CCNA 200-301 Exam?
The Cisco Certified Network Associate (CCNA) certification covers the essentials of networking. The 200-301 exam is a single exam that includes topics like:
- IP routing and switching
- Network security basics
- Wireless networking
- Device configuration
- Network automation
You only need to pass one good test instead of several.-Just one real test.But to do well, you’ll need to understand both theory and setup well.
Breakdown of CCNA Exam Topics (2025 Edition)
Cisco groups the CCNA exam into six core categories. Each category carries a different weight in terms of importance:
| Section | Weight |
|---|---|
| Network Fundamentals | 20% |
| Network Access | 20% |
| IP Connectivity | 25% |
| IP Services | 10% |
| Security Fundamentals | 15% |
| Automation & Programmability | 10% |
Let’s unpack each of these.
1. Network Fundamentals (20%)
What it covers:
- OSI and TCP/IP models
- IPv4 and IPv6 basics
- Subnetting and addressing
- Common network hardware
- Cabling and interfaces
- Basics of how data moves across networks
What to focus on:
You should be comfortable identifying devices in a network, understanding how information flows from one device to another, and calculating subnet ranges. This section builds the groundwork for everything else you’ll learn in CCNA.
Tip: Master subnetting early. Use tools and worksheets to speed up your mental math.
2. Network Access (20%)
What it covers:
- How switches work
- VLANs and their configuration
- Trunk ports and native VLANs
- Basics of STP (Spanning Tree Protocol)
- EtherChannel
- CDP and LLDP (discovery protocols)
Why it matters:
Switching is used almost everywhere — from small businesses to large enterprises. If you can’t set up VLANs or handle basic Layer 2 configs, you’ll struggle with more advanced tasks.
Tip: Set up VLANs in Cisco Packet Tracer and test ping between devices. Try breaking things and fixing them — that’s where real learning happens.
3. IP Connectivity (25%)
This is the most heavily tested section of the CCNA exam.
What it covers:
- Routing concepts (how data finds its path)
- Static routing
- Single-area OSPF
- IP addressing and masks
- How routing tables work
Why it matters:
Routing keeps networks connected. You’ll need to understand how routers make decisions, how to troubleshoot when something goes wrong, and how protocols like OSPF work behind the scenes.
Tip: Spend extra lab time on routing. Make sure you know how to configure and verify OSPF using CLI commands.
4. IP Services (10%)
What it covers:
- DHCP
- NAT
- NTP
- DNS
- QoS basics
- Syslog
- SNMP
Why it matters:
These services may not seem exciting, but they’re essential in any real network. Whether it’s assigning IP addresses automatically or allowing devices to communicate across the internet, these features keep the network running smoothly.
Tip: NAT and DHCP are often tricky at first. Practice setting up NAT inside Packet Tracer and understand what inside vs. outside interfaces mean.
5. Security Fundamentals (15%)
What it covers:
- How to secure access to devices (passwords, SSH)
- ACLs (Access Control Lists)
- Layer 2 security (e.g., port security)
- Firewall and VPN basics
- AAA concepts (Authentication, Authorization, Accounting)
Why it matters:
Security is a critical part of every network. You don’t need to be a cybersecurity expert, but you must understand how to lock down access and stop unwanted traffic.
Tip: Practice creating ACLs to allow or block traffic between networks. Use Packet Tracer to simulate basic attacks like MAC flooding and test protections.
6. Automation & Programmability (10%)
What it covers:
- What SDN (Software Defined Networking) is
- Intro to APIs (especially REST)
- Reading JSON output
- Using tools like Cisco DNA Center
Why it matters:
Networking is moving toward automation. As networks grow more complex, automation helps scale and simplify configurations. You don’t need to write Python scripts for CCNA, but understanding what APIs are and how automation works will help you stay current.
Tip: Don’t stress about coding here. Just focus on concepts — what is an API, what does JSON look like, and how network devices can be managed remotely.
What Should You Focus On the Most?
If you’re short on time, here’s how to prioritize your study time:
| Topic | Priority Level |
|---|---|
| IP Connectivity | 🔥 High |
| Network Access | 🔥 High |
| Network Fundamentals | 🔥 High |
| Security Fundamentals | ✅ Medium |
| IP Services | ✅ Medium |
| Automation & Programmability | âš¡ Light |
Spend most of your time on routing, VLANs, and device configurations. These are skills you’ll need in any real IT job, not just the exam.
Lab Practice: Where Each Topic Comes Alive
Reading theory is important, but doing the work is what gets you ready. Here’s how each topic plays out in labs:
| Topic | Example Lab |
|---|---|
| IP Connectivity | Set up OSPF between two routers |
| VLANs | Create 3 VLANs and assign PCs to them |
| NAT | Configure static and dynamic NAT |
| DHCP | Set up a DHCP pool and assign IPs to clients |
| ACLs | Block one PC from accessing another |
| SSH | Secure router access using SSH instead of Telnet |
Final Thoughts: Understanding the Exam Is Half the Battle
The CCNA exam is broad, but not impossible. When you know what’s covered and how to approach each topic, you can create a focused study plan that actually works.
Stick to the official exam topics, practice with labs, and use tools like Packet Tracer to test your skills. Take your time, ask questions in communities, and build confidence one step at a time.
