What advantage can a DHCPv6 server assign to a DHCPv6 client?

Question

Options

• AGateway address
• BDNS server address
• CNTP server address
• DSNTP server address

• A
  14% (5)
• B
  77% (27)
• C
  6% (2)
• D
  3% (1)

Explanation

DHCPv6 can assign a DNS server address to clients, making option B correct. DNS server assignment is a core function of DHCPv6 (defined in RFC 3315/8415), allowing clients to resolve hostnames after obtaining their IPv6 address configuration.

Option A is wrong because DHCPv6 does not assign a default gateway. In IPv6, the default gateway is learned through Router Advertisement (RA) messages sent by routers using the Neighbor Discovery Protocol (NDP) -- this is a key difference from DHCPv4, which can provide a gateway. Options C and D are wrong because NTP and SNTP server addresses are not standard DHCPv6 assignments in typical exam-relevant implementations; these services are either configured manually or discovered through other means.

Memory tip: Remember that IPv6 split the job -- routers advertise the Gateway via RA, while DHCPv6 handles the DNS. If you remember "DHCPv6 = DNS, RA = Gateway," you will avoid the most common trap in this question type.
