Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 117

Which of the following packets is sent by a DHCPv6 client before it sends a request packet to the DHCPv6 server?

Answer options

• A. RA
• B. RS
• C. NA
• D. NS

Correct answer: D

Explanation

The correct answer is D, as a DHCPv6 client sends a Neighbor Solicitation (NS) packet to determine the presence of a DHCPv6 server before making a request. The other options, RA (Router Advertisement), RS (Router Solicitation), and NA (Neighbor Advertisement), are related to different functions in the network configuration process and do not precede the request packet in the DHCPv6 process.
