Overview of the Cisco CCNA 200-301 Certification

The Cisco Certified Network Associate (CCNA 200-301) certification validates your ability to install, configure, operate, secure, and troubleshoot medium-sized routed and switched enterprise networks.

Rather than splitting associate-level certifications into separate tracks, Cisco consolidated the modern CCNA 200-301 exam to cover routing and switching, wireless LANs, security fundamentals, and network automation in a single comprehensive 120-minute exam.

The 6 Official CCNA 200-301 Exam Domains

The official Cisco 200-301 exam blueprint weights topics across six core engineering domains:

  • 1. Network Fundamentals (20%): Routers, Layer 2/3 switches, firewalls, access points, physical cabling, TCP/UDP, IPv4 subnetting, and IPv6 addressing.
  • 2. Network Access (20%): VLANs, 802.1Q interswitch trunking, EtherChannel (LACP), Rapid PVST+ Spanning Tree, and Cisco Wireless LAN architectures.
  • 3. IP Connectivity (25%): IPv4/IPv6 static routing, longest-prefix match, single-area OSPFv2 configuration, router ID selection, and First Hop Redundancy Protocols (FHRP).
  • 4. IP Services (10%): NAT (static, dynamic, PAT), NTP, DHCP client/relay, DNS, SNMP, Syslog, and Per-Hop QoS behavior.
  • 5. Security Fundamentals (15%): Standard and extended Access Control Lists (ACLs), Layer 2 port security, DHCP snooping, Dynamic ARP Inspection, VPN concepts, and WPA2/WPA3 wireless security.
  • 6. Automation and Programmability (10%): Controller-based SDN architectures, REST APIs, CRUD verbs, JSON data encoding, and configuration management concepts.

How the 3 Cisco NetAcad Courses Map to the Exam

Within the Cisco Networking Academy curriculum delivered at Majsystems, CCNA preparation is organized into three progressive 70-hour modules:

1. CCNA: Introduction to Networks (ITN) — Builds protocol foundations, Ethernet switching, IPv4/IPv6 addressing, and basic router/switch CLI configuration.

2. CCNA: Switching, Routing & Wireless Essentials (SRWE) — Focuses on VLANs, inter-VLAN routing, STP, EtherChannel, DHCPv4/v6, FHRP, and WLAN deployment.

3. CCNA: Enterprise Networking, Security & Automation (ENSA) — Covers single-area OSPF, WAN concepts, ACLs, NAT, VPNs, QoS, and network automation.
