   A network engineer is designing an IPv6 addressing plan for a multi-site enterprise. The company has been assigned a global unicast prefix 2001:db8:abcd::/48 by its ISP. The engineer needs to create subnets for each site and department. The engineer also wants to ensure that the addresses are stable and do not change when the ISP changes the prefix. Which of the following approaches best meets these requirements?

   • AUse unique local addresses (FC00::/7) for internal communication and global unicast addresses only for internet-facing services.
   • BUse link-local addresses for all internal communication.
   • CUse only global unicast addresses for all devices and rely on the ISP to keep the prefix stable.
   • DUse multicast addresses for internal communication.

   A network engineer is configuring a router to advertise an IPv6 prefix to hosts on a LAN. The hosts should automatically configure their own IPv6 addresses using SLAAC. The engineer wants to ensure that the hosts use the Modified EUI-64 method to generate their interface identifiers. Which configuration is required on the router?

   • AEnable IPv6 on the interface and configure a global unicast address on the router.
   • BConfigure a link-local address on the router.
   • CConfigure a DHCPv6 server on the router.
   • DConfigure a unique local address on the router.
