Many students often ask: “If I want to pass Cisco CCNA, what should I study?       Is the exam difficult?”
As a senior network engineer, I’ll explain the key learning points, exam topics, and preparation strategies for CCNA (Cisco Certified Network Associate), in a clear and beginner-friendly way.


1. What Do You Learn in CCNA?
 
CCNA is an entry-level certification designed to build skills in enterprise network setup and troubleshooting. It is suitable for beginners and mainly covers four areas:
Networking Fundamentals
OSI 7-layer model (focus from Application to Data Link layer) and TCP/IP 4-layer model;
TCP vs. UDP, IP addressing and subnetting;
ARP, ICMP and other basic protocols;
Router and switch functions and interfaces.
Routing and Switching Core (Key Focus)
Switch configuration: VLANs, Trunk links, STP loop prevention;
Router configuration: static route, default route, OSPF basics;
Inter-VLAN communication (Router-on-a-stick / Layer 3 switch);
Simple troubleshooting skills.
Network Security Basics
Device login security (console password, SSH);
Access Control Lists (ACL) for traffic filtering.
Emerging Technologies
Wireless basics: AP, SSID setup, WPA2 encryption;
Intro to Cisco DNA Center and SDN concepts (theoretical only).
 
2. What’s on the CCNA Exam?

The CCNA exam currently consists of a single written test:
Exam Code: 200-301
Format: Written, available online or at Pearson VUE test centers
Duration: 90 minutes
Passing Score: 825 / 1000
Question Types: Multiple choice, multiple select, drag-and-drop, and configuration simulation (no essay questions)
Exam Topic Weighting:
Routing & Switching – ~40% (VLANs, static routing, OSPF, ACLs, troubleshooting)
Network Fundamentals – ~25% (TCP/IP models, subnetting, IP planning)
Network Security – ~15% (SSH, ACL)
Emerging Technologies – ~10% (wireless basics, SDN concepts)
Device Management & Documentation – ~10%
The exam is not overly difficult. As long as you grasp the key points, passing is very achievable.
 
3. How to Prepare for CCNA?

Preparation doesn’t have to be complicated. Follow the principle of theory + practice + dumps drills, and even beginners can succeed.
Learn the Theory
Use Cisco’s official CCNA 200-301 Official Cert Guide (available in multiple languages);
Focus on “Routing & Switching” and “Networking Fundamentals”;
Dedicate 1–2 hours daily, and you can finish the core topics in about a month.
Practice with Simulators (for Better Understanding)
Even though the exam has no hands-on lab, practice helps comprehension.
Tools like Cisco Packet Tracer or eNSP can be used to practice VLAN, OSPF, and ACL configurations.
Drill with Dumps (The Key Step)

Practicing with a CCNA dumps is essential for passing.

CCNA is known as the “gateway certification” in networking. It is practical, not overly difficult, and serves as proof of your networking foundation. With the help of a reliable CCNA dumps, plus consistent study, most candidates can pass within 1–2 months and lay a solid foundation for future certifications like CCNP or careers in network engineering.
