Final answer:
In stateful DHCPv6, the DHCP server provides a DNS Server, Network Prefix, and an Interface Identifier to a client. Subnet masks are not used in IPv6 in the same way they are in IPv4, and the default gateway is obtained through router advertisements, not DHCPv6.
Correct option is a) Network Prefix, DNS Server, Default Gateway
Step-by-step explanation:
In stateful DHCPv6, a DHCP server provides several configurations to a client. The correct answer to what three things a DHCPv6 server provides to a client is:
- DNS Server
- Network Prefix (also known as a prefix delegation)
- Interface Identifier (used to form the client's IPv6 address)
Option (b) Interface Identifier, Subnet Mask, DNS Server might seem correct at first glance, but DHCPv6 does not typically provide a subnet mask as IPv6 does not use subnet masks in the same way IPv4 does. Instead, it uses prefix lengths to define network boundaries. Similarly, the default gateway is not provided by DHCPv6 but is discovered by the client through router advertisements. Lastly, a MAC address is usually not managed by DHCP as it is a hardware address assigned to a device, not a network configuration setting.
