A network team is monitoring a WAN link and notices that the interface utilization is consistently above 90% during business hours. They want to determine if the high utilization is due to a specific application or a network issue. Which combination of tools would provide the most useful information?

Enable 'debug ip interface' on the router.

Use SNMP to poll interface counters and NetFlow to identify top talkers.

Check syslog for interface up/down events.

Use ping to test latency and packet loss on the link.

A user reports that they cannot reach a server at 10.10.10.10 from their workstation. The workstation's default gateway is 192.168.1.1. The administrator pings the default gateway successfully, but pings to 10.10.10.10 fail. Which next step would best determine whether the problem is a routing issue or a firewall dropping packets?

Check the ARP cache on the workstation for the server's MAC address.

Enable 'debug ip packet' on the workstation's default gateway.

Run a traceroute to 10.10.10.10 and observe where the path stops or times out.

Use SNMP to query the server's interface counters.

A network engineer is troubleshooting intermittent BGP neighbor resets on a router that carries production traffic. The engineer needs to capture debug output only for BGP events involving a specific peer IP, while minimizing the impact on the router's CPU. Which approach should the engineer use?

Configure 'logging console warnings' and rely on syslog messages.

Use 'debug ip bgp 192.0.2.1 updates' with the peer IP specified.

Run 'show ip bgp neighbors 192.0.2.1' repeatedly to observe changes.

Enable 'debug ip bgp' globally and monitor the console output.

Part of the 4.0 Network Assurance domain, which accounts for 10% of the 350-401 exam. Cisco does not publish an official question count, but from its 120-minute exam (~50–80 total, ~5–8 in this domain), expect 1–1 from this objective — we provide 30 practice questions to prepare you well beyond it.
