The answer is the show ip dhcp binding and show ip dhcp pool commands. The show ip dhcp binding command directly verifies DHCPv4 server operation by displaying active leases, including the assigned IP address, MAC address, lease expiration, and binding type, proving the server is allocating addresses. The show ip dhcp pool command confirms address pool utilization by showing total addresses, leased addresses, and excluded addresses, giving you a clear view of pool consumption. On the Cisco CCNP ENARSI 300-410 exam, this question tests your ability to distinguish between operational verification and configuration display—a common trap is confusing show ip dhcp pool with show ip dhcp server statistics, which is not a valid command. Remember the memory tip: “Bindings show who’s in, pools show how much is used.”
300-410 DHCP (IPv4 and IPv6) Practice Question
This 300-410 practice question tests your understanding of dhcp (ipv4 and ipv6). Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO commands can be used to verify DHCP IPv4 server operation and address pool utilization on a Cisco IOS router? (Choose TWO.)
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
Option A is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
show ip dhcp binding
Why this is correct
Displays all active DHCP leases (IP address, MAC, lease time, etc.).

Read the scenario before looking for a memorised answer.
✓
show ip dhcp pool
Why this is correct
Shows pool name, utilization, and address ranges.
Related concept
Read the scenario before looking for a memorised answer.
✗
show ip dhcp conflict
Why it's wrong here
Shows only address conflicts, not overall pool utilization.
✗
debug ip dhcp server events
Why it's wrong here
This is a debug command, not a verification command for ongoing operation.
✗
show ip interface
Why it's wrong here
Shows interface IP status, not DHCP server details.
Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Trap categories for this question
Command / output trap
Shows only address conflicts, not overall pool utilization.
Detailed technical explanation
How to think about this question
The DHCP server on Cisco IOS uses a database of bindings stored in RAM (or optionally in NVRAM with 'ip dhcp database') to track leases. The 'show ip dhcp binding' command queries this database, while 'show ip dhcp pool' reads the pool configuration and calculates utilization by comparing the number of active bindings against the pool's defined subnet size. In real-world scenarios, these commands are essential for troubleshooting address exhaustion or verifying that the server is handing out addresses from the correct subnet.
KKey Concepts to Remember

Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 300-410 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
