1. Network Fundamentals (20%)

This domain tests your understanding of basic networking concepts:

• The OSI and TCP/IP models — understanding the 7 layers and how data flows
• IPv4 and IPv6 addressing schemes, including subnetting and CIDR notation
• Network topologies: star, mesh, ring, bus, and hybrid
• Cabling types: UTP (Cat5e, Cat6), fiber optic (single-mode, multi-mode)
• Wireless standards: 802.11a/b/g/n/ac/ax (Wi-Fi 6)
• TCP vs UDP — connection-oriented vs connectionless protocols

2. Network Access (20%)

• VLANs (Virtual LANs) — configuration, trunk ports, access ports
• Spanning Tree Protocol (STP) — preventing layer 2 loops, RSTP
• EtherChannel — LACP and PAgP for link aggregation
• Wireless architectures: autonomous AP, cloud-managed, controller-based
• 802.1Q trunking and inter-VLAN routing concepts

3. IP Connectivity (25%)

The largest exam domain, covering routing:

• Static routing — default routes, floating static routes
• OSPFv2 — single area configuration, router ID, neighbor adjacency
• Inter-VLAN routing using Router-on-a-Stick and Layer 3 switches
• First Hop Redundancy Protocols (HSRP) concepts
• Administrative distance and route selection

4. IP Services (10%)

• NAT/PAT — static, dynamic, and overload (PAT)
• DHCP — server configuration and relay agents
• DNS — name resolution process
• NTP — time synchronization
• SNMP — network monitoring (v2c, v3)
• Syslog — logging levels and configuration

5. Security Fundamentals (15%)

• Access Control Lists (ACLs) — standard, extended, named
• Port security — MAC address limiting
• AAA — Authentication, Authorization, Accounting
• VPN concepts — site-to-site and remote access
• Wireless security: WPA2, WPA3, EAP
• Layer 2 security threats: MAC flooding, ARP spoofing, VLAN hopping

6. Automation & Programmability (10%)

• REST APIs — CRUD operations, HTTP methods
• JSON and data serialization formats
• Cisco DNA Center — intent-based networking
• Configuration management tools: Ansible, Puppet, Chef
• Software-defined networking (SDN) concepts

Study Tips

1. Create a Study Plan: Allocate 2-3 months of consistent study, covering 1-2 topics per week.
2. Hands-On Practice: Use Cisco Packet Tracer or GNS3 to practice lab exercises.
3. Take Mock Exams: Use our MockExam Simulator to test your readiness.
4. Review Explanations: Do not just memorize answers — understand the "why" behind each concept.
5. Focus on Weak Areas: Track your scores by topic and spend extra time on lower-scoring domains.
