The Cisco CCNP Enterprise Core exam (350-401 ENCOR) is the foundation of the entire Cisco CCNP Enterprise certification track. Unlike the old CCNP Routing and Switching, today's CCNP Enterprise requires passing ENCOR as the core exam plus one concentration exam of your choice — whether that is SD-WAN, Advanced Routing, Wireless, or SD-Access. ENCOR is where you prove mastery of enterprise network design, infrastructure, security, and automation all at once. It is a demanding exam, but it is the right challenge for anyone serious about a senior networking career.

What ENCOR Is and Why It Matters

ENCOR stands for Enterprise Core. It is the mandatory "core" exam for every CCNP Enterprise concentration. Whether you want to specialize in SD-WAN, Advanced Routing, Wireless, or SD-Access, you must first pass ENCOR. This makes ENCOR the most strategically important exam in the Cisco Enterprise track.

ENCOR replaced the old CCNP R&S (ROUTE + SWITCH + TSHOOT three-exam system) in 2020. The new format is more demanding because it covers a broader technology scope — including SD-WAN, SD-Access, Python/Ansible automation, and AI/ML in networking — alongside traditional routing and switching.

6 Exam Domains Explained

Domain Weight Key Topics

2. Virtualization 10% NFV, virtual switching, containers, cloud connectivity models
3. Infrastructure 30% Layer 2 (VLANs, STP, EtherChannel), OSPF/EIGRP/BGP, wireless, multicast
4. Network Assurance 10% SNMP, streaming telemetry, Cisco Catalyst Center assurance, troubleshooting
5. Security 20% 802.1X, TrustSec, ACLs, VPN technologies, device hardening
6. Automation and AI 15% Python, Ansible, REST APIs, Catalyst Center APIs, YANG models, AI in networking

The Hardest Topics in ENCOR

ENCOR candidates consistently report the same challenging areas:

  • SD-WAN architecture: Understanding which component does what (vManage=management, vBond=orchestration, vSmart=control plane, vEdge/cEdge=data plane) and how OMP distributes routes in the overlay.
  • SD-Access fabric roles: Edge Node vs Border Node vs Control Plane Node, LISP for location/identity separation, VXLAN for transport.
  • BGP: ENCOR covers BGP basics — enough to understand how it works and configure basic eBGP/iBGP, but not the depth of the Advanced Routing concentration.
  • QoS: DSCP marking values, queuing mechanisms (CBWFQ vs LLQ), and policy-map configuration.
  • Automation domain: Candidates strong in networking but weak in Python/APIs struggle here. Invest time in this domain — it represents 15% of the exam.
💡 Study Tip: Infrastructure (Domain 3) is 30% of the exam — the single largest domain. If you only have time to go deep on one domain, make it Infrastructure. OSPF, EIGRP, and Layer 2 are your highest-yield topics.

6-Month Study Plan

  • Month 1: Infrastructure Part 1 — VLANs, STP/RSTP, EtherChannel, Inter-VLAN routing, Layer 2 security
  • Month 2: Infrastructure Part 2 — OSPFv2/v3 multi-area, EIGRP, BGP basics, IPv6
  • Month 3: Architecture — SD-WAN components and design, SD-Access fabric, QoS DSCP/queuing, wireless 802.11
  • Month 4: Security and Network Assurance — 802.1X, TrustSec, ACLs, DMVPN/FlexVPN, SNMP/streaming telemetry
  • Month 5: Automation and Virtualization — Python scripting, REST API calls, Ansible playbooks, NETCONF/YANG, NFV concepts
  • Month 6: Full practice exams, hands-on labs in DevNet sandbox and GNS3/EVE-NG. Aim for 80%+ on practice before booking.

Career Value and Salaries

CCNP Enterprise is one of the most respected networking certifications in the industry. Combined with 3–5 years of experience, it positions you for senior roles:

Role Avg Salary (US)
Senior Network Engineer $95,000–$125,000
Network Architect $120,000–$155,000
SD-WAN Engineer $105,000–$135,000
