2 hands-on DNS scenarios you build in your own Cisco Modeling Labs instance and grade against the answer key. Focused DNS configuration and troubleshooting practice for CCNA and CCNP.
Troubleshoot a pre-broken monitoring deployment on a single shared management LAN. R1 is already configured for discovery and monitoring, but the NMS receives no syslog or SNMP traps from R1. Diagnose with show commands and correct the two seeded faults: wrong syslog target and missing SNMP trap generation. Deterministic, no-routing, single-subnet design for CML Free (5 nodes).
Enable and verify DNS-based name resolution on Cisco IOS. R1 will use a central DNS resolver on the management LAN and also maintain a static host mapping for R2, demonstrating resolution order and operational differences between local host tables and DNS queries.
