- A
The DHCP server has 150 active automatic bindings and 5 manual bindings.
The output shows 'Automatic bindings: 150' and 'Manual bindings: 5', indicating the number of active leases.
- B
The DHCP server has received 200 DHCPREQUEST messages.
Why wrong: The output shows 180 DHCPREQUEST messages received, not 200.
- C
The DHCP server has 10 malformed messages, indicating a configuration issue.
Why wrong: Malformed messages are 0, so no malformed messages were received.
- D
The DHCP server has 2 database agents configured.
Why wrong: Database agents are 0, meaning no external database is used for lease storage.

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.
A network engineer runs the following command to verify DHCPv4 server statistics on router R1:
R1# show ip dhcp server statistics
Output: Memory usage: 12345 Address pools: 2 Database agents: 0 Automatic bindings: 150 Manual bindings: 5 Expired bindings: 10 Malformed messages: 0
Message Received
BOOTREQUEST 0
DHCPDISCOVER 200 DHCPREQUEST 180 DHCPDECLINE 2 DHCPRELEASE 5 DHCPINFORM 10
What does this output indicate?
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
✓
The DHCP server has 150 active automatic bindings and 5 manual bindings.
Option A is correct because the 'Automatic bindings: 150' and 'Manual bindings: 5' fields directly indicate the number of active leases assigned dynamically (via DHCP) and statically (via manual configuration), respectively. These represent the current active bindings on the DHCP server, with no other interpretation needed.
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.
- ✓
The DHCP server has 150 active automatic bindings and 5 manual bindings.
Why this is correct
The output shows 'Automatic bindings: 150' and 'Manual bindings: 5', indicating the number of active leases.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
The DHCP server has received 200 DHCPREQUEST messages.
Why it's wrong here
The output shows 180 DHCPREQUEST messages received, not 200.
- ✗
The DHCP server has 10 malformed messages, indicating a configuration issue.
Why it's wrong here
Malformed messages are 0, so no malformed messages were received.
- ✗
The DHCP server has 2 database agents configured.
Why it's wrong here
Database agents are 0, meaning no external database is used for lease storage.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the ability to distinguish between message types in the 'Received' table, specifically confusing DHCPDISCOVER with DHCPREQUEST counts, as candidates may misread the output under time pressure.
Trap categories for this question
Command / output trap
The output shows 180 DHCPREQUEST messages received, not 200.
Detailed technical explanation
How to think about this question
The 'show ip dhcp server statistics' command provides a snapshot of DHCP server activity, including counters for each message type (e.g., DHCPDISCOVER, DHCPREQUEST) and binding counts. Automatic bindings are leases dynamically assigned from a pool, while manual bindings are static assignments based on client MAC addresses; expired bindings are leases that have timed out and are available for reuse. In real-world scenarios, a high number of DHCPDECLINE messages could indicate IP address conflicts, but here the count is low.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- 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.
