The CCNA 200-301 exam blueprint, as established in 2020 and updated to version 1.1 in 2024, organizes the tested content into six main domains, each with a specific weighting to reflect their relative importance in foundational networking knowledge. These domains are Network Fundamentals (20%), Network Access (20%), IP Connectivity (25%), IP Services (10%), Security Fundamentals (15%), and Automation and Programmability (10%).^[2] This structure ensures candidates demonstrate proficiency across core networking principles, with a balanced emphasis on theoretical understanding and practical application.

• Network Fundamentals (20%): Candidates must explain the roles of network components such as routers, Layer 2 and Layer 3 switches, next-generation firewalls, and access points, alongside describing characteristics of network topologies like two-tier, three-tier, spine-leaf, WAN, and small office/home office architectures. Key subtopics include the OSI and TCP/IP models for understanding layered network communication; comparisons of physical interface and cabling types, such as copper, fiber, and wireless; configuration and verification of IPv4 addressing, subnetting, and IPv6 addressing schemes; and descriptions of wireless principles, including non-overlapping Wi-Fi channels and access point coverage areas. Virtualization fundamentals, such as server and network virtualization using hypervisors, are also covered to address modern infrastructure concepts.^[2]
• Network Access (20%): This domain focuses on Layer 2 technologies, requiring configuration and verification of VLANs (spanning trunks and access ports), interswitch connectivity using trunking protocols like 802.1Q, and native VLAN configurations to prevent issues like VLAN hopping. Ethernet switching concepts, including MAC learning and aging, frame forwarding methods (flooding, unicast, multicast, broadcast), and Layer 2 access ports for hosts and trunks for interconnecting switches, form a core part. Other subtopics encompass Layer 2 discovery protocols such as Cisco Discovery Protocol and Link Layer Discovery Protocol for device identification; EtherChannel configurations for link aggregation; interpretation of Rapid Per-VLAN Spanning Tree Plus (PVST+) operations to avoid loops; descriptions of Cisco wireless architectures, including controllers, access points, and Wireless LAN components, with updates incorporating Wi-Fi 6 standards for enhanced performance in dense environments; and descriptions of network device management access (Telnet, SSH, HTTP, HTTPS, console, TACACS+/RADIUS, and cloud managed).^[2]
• IP Connectivity (25%): This domain emphasizes routing essentials, including interpretation of routing table components like prefix, network mask, next hop, and administrative distance. Candidates configure and verify IPv4 and IPv6 static routing, as well as single-area OSPFv2 for dynamic routing in IPv4 environments, with basic understanding of OSPF neighbor adjacencies and LSDB operations. Although earlier versions referenced EIGRP, the current blueprint prioritizes OSPF while allowing potential testing on EIGRP concepts in practical scenarios. First-hop redundancy protocols, such as Hot Standby Router Protocol (HSRP) for gateway redundancy, are described to ensure high availability. This domain highlights practical routing troubleshooting over pure theory.^[2]
• IP Services (10%): This domain covers essential network services, requiring configuration and verification of Network Address Translation (NAT) for inside source and overload scenarios, along with Network Time Protocol (NTP) for time synchronization and Dynamic Host Configuration Protocol (DHCP) for automated IP assignment on routers. Explanations of supporting protocols include DHCP relay and pool operations, Domain Name System (DNS) for name resolution, Simple Network Management Protocol (SNMP) for device monitoring, and syslog for logging events. Quality of Service (QoS) concepts, such as classifying traffic and forwarding per-hop behavior, provide context for traffic prioritization without deep implementation details.^[2]
• Security Fundamentals (15%): This domain introduces core security principles, defining key concepts like confidentiality, integrity, availability, and authentication, while describing elements of Cisco's security program such as defense-in-depth and zero-trust models adopted since the 2020 blueprint to emphasize identity-based access over perimeter defenses. Practical tasks include configuring device access control using local passwords, AAA with RADIUS and TACACS+, and external authentication methods; implementing Access Control Lists (ACLs) for IPv4 traffic filtering by permitting or denying based on source/destination and ports; and describing REST APIs for secure integration. Wireless security protocols, including WPA2 PSK and WPA3 for enterprise protection, and IPsec VPN fundamentals for site-to-site connectivity, round out the domain with a focus on scenario-based application.^[2][12]
• Automation and Programmability (10%): This domain addresses emerging trends, explaining how automation reduces human error and enables scalable networks through controller-based architectures like Cisco DNA Center. Software-defined networking (SDN) concepts, including separation of control and data planes, are described alongside traditional networks. Key subtopics involve REST-based APIs for programmatic control, data formats like JSON and XML, and authentication methods such as basic and token-based. Configuration management tools like Ansible, Puppet, and Chef are recognized for infrastructure as code, with basic Python scripting for automation tasks, such as reading Cisco IOS-XE configurations or using NETCONF for data retrieval; and explaining AI (generative and predictive) and machine learning in network operations. This domain underscores practical programmability over advanced coding.^[2]

Overall, the blueprint places higher emphasis on IP Connectivity and Security Fundamentals, which together account for 40% of the exam, prioritizing hands-on scenarios like configuring VLANs or ACLs in simulated environments rather than rote memorization of theory. Since the 2020 introduction, updates have integrated modern elements, such as Wi-Fi 6 for next-generation wireless and zero-trust security models, to align with evolving industry practices like cloud integration and AI-driven automation.^[1][12]
