What should you study for the CCNP Enterprise (ENCOR) exam?

To pass the CCNP Enterprise (ENCOR) certification exam, you should focus on:

  • Architecture: Covers enterprise network design including 2-tier, 3-tier, and spine-leaf architectures, SD-WAN, SD-Access, and cloud connectivity.
  • Virtualization: Covers network virtualization including VRFs, GRE/IPSec tunnels, VXLAN, and server virtualization concepts.
  • Infrastructure: Covers Layer 2 (STP, VLANs, EtherChannel), Layer 3 routing protocols (OSPF, EIGRP, BGP), QoS, and wireless infrastructure.
  • Network Assurance: Covers network monitoring, troubleshooting methodologies, IP SLA, NetFlow, SNMP, Syslog, and Cisco DNA Center assurance features.
  • Security: Covers network security including device hardening, AAA, 802.1X, DHCP snooping, Dynamic ARP Inspection, and control plane protection.
  • Automation: Covers network programmability, REST APIs, Python scripting, Ansible, YANG data models, NETCONF, RESTCONF, and Cisco DNA Center APIs.

The exam tests your ability to apply concepts in real scenarios, not just memorize definitions.
