Month 1
Network Fundamentals & IP Connectivity
Tip: Master subnetting before moving on — it appears in multiple domains.
Month 2
Network Access (VLANs, STP, EtherChannel)
Tip: Draw STP topology diagrams by hand to internalise port states.
Month 3
IP Services & Security Fundamentals
Tip: Understand NAT types and ACL placement rules — they generate exam traps.
Month 4 (Final 4 wks)
Automation, Weak Domains & Mock Exams
Tip: Use Courseiva domain analytics to target your lowest-accuracy areas. Book your exam date now — candidates with a fixed deadline pass at higher rates.
Subnetting is tested across multiple question types — master it completely before sitting the exam.
STP port states (Blocking, Listening, Learning, Forwarding) are a perennial exam topic with deliberate distractors.
CDP vs LLDP, NTP, DHCP relay — know the operational differences, not just definitions.
The Automation & Programmability domain (10%) is often under-studied. Don't skip it.
Book your exam date before you feel ready — candidates with a fixed deadline pass at higher rates.
Apply everything in this guide with adaptive practice questions, detailed answer explanations, and domain analytics.
Deep-dive explanations of the key topics tested on 200-301 — with exam key points and common misconceptions.
Spanning Tree Protocol
Plug two switches together with two cables and watch your network die.
IPv4 Subnetting
Subnetting is the skill that separates people who understand networking from people who just use it.
OSPF
Static routes break the moment a link goes down and nobody updates the config.
VLANs & Trunking
Without VLANs, every device on a switch is in the same broadcast domain.
Access Control Lists
An access control list is the gatekeeper on a router interface.
OSI & TCP/IP Models
Every time you load a webpage, seven invisible layers of technology coordinate to make it happen and most people could not name three of them.
Ethernet & Switching
Ethernet is the technology that connects almost every wired device in the world.
IPv6
IPv4 has roughly 4.
Static Routing & AD
Before a router can forward a packet somewhere, it needs to know how to get there.
NAT & PAT
Your home router gives your laptop a private IP address like 192.
DHCP & DNS
Two protocols make modern networks usable without any configuration from end users.
FHRP / HSRP
Devices on a network are configured with one default gateway address.
Wireless 802.11
Wi-Fi looks simple from the user side.
Layer 2 Security
Firewalls and intrusion detection systems protect the perimeter, but your switch infrastructure has its own set of vulnerabilities that operate entirely at Layer 2, below where most perimeter defenses look.
EtherChannel / LACP
Connect two switches with two cables and Spanning Tree will block one of them to prevent a loop.
Network Automation
Configuring a hundred switches one SSH session at a time does not scale.
NTP, SNMP & Syslog
Some of the most important things a network does happen in the background, invisible to users until they break.
Network Components
The CCNA 200-301 exam opens with network components — the physical and logical building blocks of every enterprise network.
Network Topologies
Network topology is the physical and logical layout of how devices connect.
Network Cabling
Physical layer knowledge is foundational for the CCNA 200-301 exam.
IPv6 Address Types
IPv6 address types appear throughout the CCNA 200-301 exam — in routing, neighbor discovery, and troubleshooting questions.
IP Verification Commands
Verifying IP address configuration on end hosts is a basic but exam-tested CCNA skill.
Virtualization & VRF
Virtualization appears on the CCNA 200-301 exam from two angles: compute virtualization (virtual machines and containers that run software) and network virtualization (VRFs that partition routing tables).
VLAN Types
VLANs are one of the most heavily tested topics on the CCNA 200-301 exam.
Inter-VLAN Routing
VLANs separate broadcast domains, but they also isolate devices in different VLANs from each other.
Wireless Architecture
Wireless LAN architecture is a significant topic area on CCNA 200-301 exam.
WLAN Configuration
The CCNA 200-301 exam tests your ability to configure and verify a WLAN using the Wireless LAN Controller GUI.
Device Management
Managing network devices securely is a core CCNA 200-301 topic.
Routing Table
The routing table is the decision engine of every router.
OSPF Detail
OSPF is the most heavily tested routing protocol on CCNA 200-301.
NAT Types
Network Address Translation (NAT) is how almost every private network connects to the internet.
IPsec VPN
VPNs (Virtual Private Networks) create encrypted tunnels over untrusted networks like the internet.
AAA Framework
AAA — Authentication, Authorization, and Accounting — is the security framework that controls who can access network devices, what they can do, and tracks what they did.
Wireless Security (WPA)
Wireless security is a required topic on CCNA 200-301.
TCP vs UDP
TCP and UDP are the two transport layer protocols that virtually all application traffic uses.
QoS Fundamentals
Quality of Service (QoS) is how networks prioritize traffic to ensure time-sensitive applications like voice and video receive the bandwidth and low latency they need, even when the network is congested.
Security Fundamentals
Security fundamentals form 15% of the CCNA 200-301 exam.
TFTP & FTP
TFTP and FTP are the two file transfer protocols used to manage Cisco IOS images, configuration files, and other network device files.
