Cisco CCNP Enterprise Core (350-401 ENCOR)

Enterprise teams that support campus, branch, wireless, and routed infrastructure need a shared understanding of core Cisco networking before they can standardize designs, reduce outages, and prepare for CCNP-level validation. This course fits network engineering teams with roughly three to five years of infrastructure experience who need structured coverage of enterprise design, high availability, wireless, SD-WAN, SD-Access, QoS, virtualization, Layer 2 troubleshooting, routing, access control, and API security.

For an IT Director or Training Manager, the scope is broad rather than introductory: plan for a meaningful per-learner time investment across dozens of skills, making it best suited for engineers responsible for production network changes, escalation support, or certification readiness. Because the catalog positions this training around the 350-401 ENCOR core exam, it can support a team standardization effort where some engineers need exam prep and others need a refresh on enterprise core technologies.

This training is especially useful when teams are aligning on modern enterprise architectures alongside traditional switching and routing foundations. CBT Nuggets features like Playlists and Team Reporting can help organize assignment paths and track completion across the team.

IT teams complete ENCOR training to build consistency across the environments they manage every day — from campus switching and routing to wireless and software-defined deployments. The course map emphasizes both design concepts and verification/troubleshooting work, which makes it relevant for teams that not only deploy infrastructure but also support it under production pressure.

• Standardize network design discussions with shared coverage of the hierarchical network model, enterprise network design, and high-availability techniques.
• Improve troubleshooting readiness for common switching issues through focused work on 802.1Q trunking, EtherChannel/LAG, STP, Rapid STP, and MST.
• Strengthen routed-network operations with core routing topics including EIGRP, OSPF, OSPFv3 for IPv6, NSSA configuration, summarization/filtering, and BGP foundations.
• Support modernization efforts by giving engineers common language around WLAN design, SD-WAN, SD-Access, device/data-path virtualization, QoS, device access control, ACLs, CoPP, and REST API security.

For organizations balancing uptime, change control, and certification goals, that breadth helps reduce knowledge silos across the network team.

Knowledge

• Enterprise network design fundamentals, including the hierarchical network model and broader enterprise design principles.
• High-availability approaches used in Cisco enterprise environments.
• Core concepts behind WLAN design, wireless AP modes, antenna types, joining, and roaming.
• Foundational principles of SD-WAN, SD-Access, QoS, LISP, VXLAN, and device/data-path virtualization.
• Layer 2 and Layer 3 technologies central to enterprise operations, including trunking, EtherChannel, STP variants, EIGRP, OSPF, OSPFv3, and BGP foundations.
• Security-related control concepts such as device access control, ACLs, CoPP, and REST API security.

Ability

• Explain and compare enterprise deployment models, including on-premises and cloud-oriented approaches.
• Identify Cisco SD-WAN and SD-Access components, services, and fabric operation at a level appropriate for CCNP Enterprise core study.
• Configure and verify selected enterprise networking features, including OSPF, OSPFv3, NSSA behavior, access controls, CoPP, and data-path virtualization technologies.
• Troubleshoot common campus and switching issues involving 802.1Q trunking, EtherChannel/LAG, and spanning tree operation.
• Apply QoS marking strategy concepts and distinguish between switching mechanisms in enterprise networks.
• Prepare for the 350-401 ENCOR exam while building a stronger shared baseline for production network operations.
