Implementing Cisco Enterprise Network Core Technologies (350-401 ENCOR)

There is a clear difference between keeping a network running and truly engineering it. The first is about reacting to alarms; the second is about understanding why traffic takes a particular path, how a failure will ripple through the design, and how to change hundreds of devices safely. Implementing Cisco Enterprise Network Core Technologies (350-401 ENCOR) is the course that helps professionals make that step.

The content moves in a logical sequence. It begins with design: how enterprise networks are structured, why redundancy and stateful switchover matter, and how QoS policies shape traffic. Next comes the switching and routing core, where you will troubleshoot trunks and EtherChannels, tune Spanning Tree with root guard and BPDU guard, and build OSPF and eBGP configurations for both IPv4 and IPv6.

The third stage is virtualization. You will look at hypervisors, virtual machines, and virtual switching, then configure VRF and secure GRE and IPsec tunnels. Overlay concepts, including VXLAN and LISP, set the scene for Cisco SD-Access and Catalyst SD-WAN.

The fourth stage focuses on assurance and network security. Here you will diagnose problems with conditional debugs, traceroute, SNMP, and syslog, collect flow data with Flexible NetFlow, and protect the control plane and management access with CoPP, ACLs, and AAA.

The final stage is network automation and AI-assisted operations. You will interpret Python code, construct JSON, understand YANG models, use NETCONF and RESTCONF, and see how Cisco Catalyst Center applies both traditional and AI-powered workflows.

By following this path, the Cisco ENCOR training gives you a complete, exam-aligned view of modern enterprise network technologies.

Course Objectives

What you will be able to do after the course:

• Design with intent: Explain 2-tier, 3-tier, fabric and cloud-based enterprise designs, and interpret QoS configurations.
• Run a stable Layer 2: Troubleshoot 802.1Q trunks and EtherChannels, and configure RSTP and MST with Spanning Tree protection features.
• Route with confidence: Configure OSPFv2/v3 with multiple areas, summarisation and filtering; build eBGP peerings; and describe policy-based routing.
• Keep services available: Implement HSRP, VRRP and NAT/PAT, interpret NTP and PTP configurations, and describe core multicast operation.
• Virtualize the network: Configure VRF, GRE and IPsec, and explain SD-Access and Catalyst SD-WAN control and data planes.
• Protect and observe: Apply AAA, ACLs and CoPP, and use Flexible NetFlow, SPAN/RSPAN/ERSPAN and IP SLA for monitoring and troubleshooting.
• Automate the routine: Work with Python, JSON, YANG, NETCONF, RESTCONF and EEM applets to automate configuration and data collection.
