300-410 DHCP (IPv4 and IPv6) Practice Question
This 300-410 practice question tests your understanding of dhcp (ipv4 and ipv6). This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 DHCPv6 message is used by a server to respond to a SOLICIT with available configuration parameters?

Correct answer & explanation
✓
ADVERTISE
In DHCPv6, when a client sends a SOLICIT message to discover available DHCPv6 servers, each server that can provide configuration parameters responds with an ADVERTISE message. This ADVERTISE message contains the server's preference and available configuration options, allowing the client to select the appropriate server. This process is defined in RFC 8415 and mirrors the DHCPv4 OFFER step.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
REPLY
Why it's wrong here
REPLY is used to respond to REQUEST, RENEW, etc., not to SOLICIT.

ADVERTISE
Why this is correct
ADVERTISE is the response to SOLICIT in DHCPv6.

RECONFIGURE
Why it's wrong here
RECONFIGURE is sent by the server to trigger a client to renew.

INFORMATION-REQUEST
Why it's wrong here
INFORMATION-REQUEST is used by clients to request options without address assignment.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between DHCPv6 message types, and the trap here is confusing ADVERTISE with REPLY, as candidates may incorrectly assume the server directly sends configuration parameters (REPLY) in response to a SOLICIT, overlooking the two-step discovery process.
Detailed technical explanation
How to think about this question
The DHCPv6 SOLICIT/ADVERTISE exchange is part of the four-message handshake (SOLICIT, ADVERTISE, REQUEST, REPLY) used for stateful address assignment. The ADVERTISE message includes a Preference option (option 7) that allows the client to choose the most preferred server; if multiple servers respond, the client selects the one with the highest preference value. In a real-world scenario, a misconfigured DHCPv6 relay agent might drop ADVERTISE messages, causing clients to fail to obtain addresses even if servers are reachable.
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.
