What makes the ENSLD hard
ENSLD is the odd one out among CCNP Enterprise concentrations because it tests design judgement rather than configuration. There are no CLI outputs to read; the questions describe a requirement and ask which design meets it. Engineers who pass ENARSI easily often find this one harder, because the wrong answers are all technically valid designs, just not the best one for the constraints given.
Addressing and routing, and campus design, are 25% each. Routing covers structured IPv4 and IPv6 plans, stable and scalable IS-IS, EIGRP, OSPF and BGP designs, and IPv6 migration by overlay, dual-stack or translation. Campus covers FHRPs, STP scalability, PoE, Layer 2 security, multicampus Layer 3 design, and SD-Access architecture. WAN at 20% includes Layer 2 VPN, MPLS L3VPN, SD-WAN customer edge, DMVPN and GET VPN. Network services covers QoS policies, management network design and multicast. Automation is 10%: YANG model families, NETCONF versus RESTCONF, telemetry, and the cloud connectivity options v1.1 added.
