Explanation

There's an error in this question's answer key worth flagging: based on RFC 3315/RFC 8415, D (Solicit) is the correct answer, not B.

Why D (Solicit) is actually correct: When a client sends a Solicit message, the DHCPv6 server responds with an Advertise message - not a Reply. The Solicit/Advertise exchange is the discovery phase (analogous to DHCPv4's Discover/Offer), and the Reply comes later in response to a Request.

Why the distractors are wrong:

• A (Renew) - The server replies with a Reply to extend a client's lease.
• B (Release) - The server sends a Reply to acknowledge that the client is giving up its address. RFC 8415 §18.3.9 explicitly states this.
• C (Rebind) - Like Renew, the server responds with a Reply; Rebind is just the fallback when Renew goes unanswered.

Memory tip: The full DHCPv6 exchange follows SARR - Solicit → Advertise → Request → Reply. The A in SARR is the giveaway: only Solicit breaks the pattern of getting a Reply. Everything after (Request, Renew, Rebind, Release, Decline) ends in a Reply.

If this came from a practice exam or textbook, the answer key appears to be incorrect. Verify against RFC 8415 before your exam.
