The correct interpretation is that the DHCP server has dynamically assigned three IP addresses to clients, as indicated by the Automatic type in the output. This is because the show ip dhcp binding command displays active DHCP bindings, where each row represents a lease with the assigned IP address, a client identifier (typically the MAC address or relay-agent ID), the lease expiration time, and the binding type—Automatic meaning the address was dynamically allocated from a pool. On the Cisco CCNP ENARSI 300-410 exam, this command tests your ability to verify DHCPv4 server operations and troubleshoot lease assignments; a common trap is misreading the client-ID field, which may show a dotted hexadecimal MAC or a longer relay-agent identifier, not always a simple MAC. Remember that Automatic bindings are dynamic, while Manual bindings indicate static reservations—a key distinction for DHCP configuration questions. A useful memory tip: “Auto means dynamic, Manual means static—check the type column first.”
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 bindings on router R1:
R1# show ip dhcp binding
Output:
Bindings from all pools not associated with VRF:
IP address Client-ID/ Lease expiration Type
Hardware address/
User name
192.168.1.10 0050.7966.6800 Mar 01 2025 12:00 PM Automatic
192.168.1.11 0063.6973.636f.2d30 Mar 01 2025 01:00 PM Automatic
192.168.1.12 0100.1a.2b.3c.4d.5e Mar 01 2025 02:00 PM Automatic
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 dynamically assigned three IP addresses to clients.
The show ip dhcp binding command displays active DHCP bindings. The output shows three active leases with IP addresses, client identifiers (MAC addresses or relay-agent IDs), lease expiration times, and the type (Automatic meaning dynamically assigned).
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 three static bindings configured.
Why it's wrong here
The type is 'Automatic', indicating dynamic assignments, not static.
✓
The DHCP server has dynamically assigned three IP addresses to clients.
Why this is correct
Each entry shows an IP address, client identifier, lease expiration, and type 'Automatic', confirming dynamic assignments.
Related concept
Read the scenario before looking for a memorised answer.
✗
The DHCP server is out of IP addresses because all bindings are in use.
Why it's wrong here
The output only shows three bindings; it does not indicate whether the pool is exhausted.
✗
The DHCP server is using relay agents because the client IDs are long hexadecimal strings.
Why it's wrong here
Client IDs can include MAC addresses or relay-agent IDs, but this does not necessarily indicate relay agents are in use.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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
→Underline the problem statement mentally.
→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.
