Cisco CCNP Enterprise (350-401 ENCOR) — Study Guide
Free, topic-by-topic study notes for the Cisco CCNP Enterprise (350-401 ENCOR) exam. Read a chapter, then practice it.
Enterprise Network Architecture
This chapter covers enterprise campus design models, the separation of network planes, Cisco SD-Access fabric concepts, and wireless deployment models. These architectural foundations frame how the rest of the ENCOR topics fit together.
Virtualization
This chapter covers device and network virtualization, including virtual machines versus containers, VRFs for path isolation, and tunneling technologies such as GRE. Virtualization lets one physical infrastructure host many logical networks and services.
Infrastructure: Switching, Routing, and Overlays
The largest ENCOR domain, infrastructure covers Layer 2 switching (VLANs, trunking, spanning tree, EtherChannel), Layer 3 routing with OSPF and BGP, first-hop redundancy, and VXLAN overlays. This chapter also folds in the network assurance mindset of verifying that these behave as intended.
Network Security
This chapter covers infrastructure and access security, including Layer 2 protections, 802.1X authentication, AAA with RADIUS and TACACS+, and secure device management. Security is woven through every layer of an enterprise network.
Network Automation and Programmability
This chapter covers the data formats, programmatic interfaces, and controller-based models that make networks programmable. Automation reduces manual, error-prone CLI work and enables consistent configuration at scale.
