2 hands-on Sticky MAC scenarios you build in your own Cisco Modeling Labs instance and grade against the answer key. Focused Sticky MAC configuration and troubleshooting practice for CCNA and CCNP.
Two access-layer switches have a VLAN 20 connectivity problem: users in one wiring closet cannot reach users in the other. Diagnose and repair the issue, then deploy sticky secure MAC learning on the host-facing access ports so each port dynamically learns and persists its connected host's MAC. Verify sticky entries in show commands and confirm same-VLAN host connectivity end-to-end.
Advanced CCNA switchport port-security rollout on multiple access ports across two Layer-2 switches with a trunk. You will standardize a consistent edge policy (sticky MAC learning, maximum 1, violation restrict) on all host-facing access ports while leaving the uplink trunk exempt from port-security. Includes a realistic drift on the trunk allow-list and VLAN database to fix before validating end-to-end user VLAN transport. Pure Layer-2: no SVIs or routing.
