Cisco ENCOR 350-401 study guide
Cisco ENCOR 350-401 · Work through your exam, one topic at a time.
The Cisco ENCOR 350-401 exam, formally Implementing Cisco Enterprise Network Core Technologies, is the core written exam on the CCNP Enterprise path. Candidates typically work as enterprise network engineers, administrators, or architects who design, deploy, and operate Cisco campus, branch, and WAN infrastructure, and who need to prove breadth across routing, switching, wireless, security, virtualization, assurance, and automation rather than depth in a single track. The Cisco ENCOR 350-401 study guide has 6 sections and about 2,473 words.
01Architecture
The Architecture domain (about 15% of ENCOR) tests whether you can choose and explain designs rather than just configure interfaces: hierarchical and spine-leaf topologies, Cisco SD-Access and SD-WAN fabrics, first-hop redundancy, and management-plane protocols. Classic campus: access-distribution-core.
414 words, about 2 min02Virtualization
Virtualization (about 10%) tests the abstraction layers: hypervisors and virtual switches, network-function virtualization, and the device-level overlays that let one physical topology carry many logical networks. A Type 1 hypervisor runs directly on hardware (ESXi, Hyper-V); Type 2 runs on a host OS.
432 words, about 2 min03Infrastructure
The Infrastructure domain is the largest ENCOR area (about 30%). It tests configuration-level understanding of Layer 2 switching, Layer 3 routing, IP services, and wireless, with an emphasis on how features interact.
445 words, about 2 min04Network Assurance
Network Assurance (about 10%) tests whether you can find the fault and prove the fix: structured troubleshooting, show/debug/packet-level tools, flow and telemetry data, and controller-based assurance. Define the problem in measurable terms, gather facts, analyze, eliminate causes, propose and test a hypothesis, then document.
395 words, about 2 min05Security
Security (about 15%) tests identity and access control at Layer 2 and Layer 3, control-plane protection, and encrypted transport. AAA separates authentication, authorization, and accounting.
406 words, about 2 min06Automation
Automation (about 20%) tests data formats and APIs, model-driven configuration, scripting, and orchestration tools - the vocabulary and mechanics behind DNA Center and SD-WAN programmability. JSON: objects in braces, arrays in brackets, strings in double quotes; no comments.
