300-410 Practice Question: Which TWO commands can be used to verify DHCP…
Which TWO commands can be used to verify DHCP IPv4 server operation and address pool utilization on a Cisco IOS router? (Choose TWO.)
⚠ Common exam trap
Cisco often tests the distinction between verification commands (show) and troubleshooting/debugging commands (debug), leading candidates to mistakenly select 'debug ip dhcp server events' as a verification tool when it is actually a real-time diagnostic command that can impact router performance.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
show ip dhcp binding
The 'show ip dhcp binding' command displays the list of active DHCP address bindings, including the IP address, MAC address, lease expiration, and type (automatic, manual, or dynamic). This directly verifies that the DHCP server is operating and has allocated addresses from its pool. Option B is correct because the 'show ip dhcp pool' command shows the pool name, utilization statistics (e.g., total addresses, leased addresses, and excluded addresses), and pool configuration, confirming address pool utilization.
