Cisco ENNA 300-445 study guide
Cisco ENNA 300-445 · Work through your exam, one topic at a time.
The Cisco ENNA 300-445 exam is a concentration exam in Cisco's associate-level certification track that focuses on enterprise networking, security, and automation. It is aimed at candidates who already hold foundational networking knowledge and want to demonstrate practical skills across routing and switching, WAN access, network security controls, and programmatic network management. The Cisco ENNA 300-445 study guide has 6 sections and about 2,473 words.
01Network Fundamentals
This domain tests how data moves from an application to the wire and back: OSI and TCP/IP layering, Ethernet media and framing, IPv4/IPv6 addressing and subnetting, switching logic, wireless principles, virtualization, and common topology architectures. Expect questions that ask you to choose the correct layer, media, address, or forwarding decision rather than recite definitions.
389 words, about 2 min02Network Access
This domain covers how endpoints join the enterprise LAN and WLAN: VLAN segmentation, 802.1Q trunks, EtherChannel, Spanning Tree Protocol, and wireless deployment with controllers and AP modes. Questions often present a topology symptom and ask which access-layer setting is wrong.
426 words, about 2 min03IP Connectivity
This domain tests the forwarding plane and control plane for IPv4 and IPv6: reading the routing table, static routing, OSPFv2/v3, and first-hop redundancy. Expect route-selection and neighbor-adjacency scenarios.
408 words, about 2 min04IP Services
This domain covers the supporting services that make a network usable: NAT, DHCP, DNS, NTP, SNMP, syslog, QoS, and file transfer. The exam favors operational details such as port numbers, translation behavior, and severity levels.
405 words, about 2 min05Security Fundamentals
This domain tests the security controls that protect enterprise access and transit: AAA, ACLs, Layer 2 defenses, VPN concepts, and wireless security. Questions often ask where a control is applied and what it actually inspects.
427 words, about 2 min06Automation and Programmability
This domain tests how modern networks are controlled and configured programmatically: SDN architecture, controller-based networking, REST APIs, data formats, configuration management, and basic Python. Expect questions that compare traditional CLI workflows with controller and API workflows.
