   A service provider wants to offer a well-known IPv6 address for its DNS resolvers. The same address should be assigned to multiple servers in different data centers. When a client sends a query to that address, the network should deliver the packet to the nearest available server. Which IPv6 address type should be used for this purpose?

   • AUnique local address
   • BMulticast address
   • CAnycast address
   • DGlobal unicast address assigned to each server individually

   What is a key characteristic of an IPv6 link-local address?

   • AIt is automatically configured on every IPv6-enabled interface
   • BIt is used for communication between different sites
   • CIt is globally routable on the Internet
   • DIt is assigned by a DHCPv6 server

   A network engineer is planning IPv6 addressing for a new branch office. The ISP has assigned a /48 global routing prefix. The engineer needs to create multiple subnets within the branch and ensure that each subnet has a unique subnet ID. Which part of the global unicast address should the engineer use for subnetting?

   • AThe interface ID, which is generated using Modified EUI-64.
   • BThe link-local prefix, which is FE80::/10.
   • CThe global routing prefix, which is assigned by the ISP.
   • DThe subnet ID field, which is the portion between the global routing prefix and the interface ID.

   What is the purpose of the Modified EUI-64 process in IPv6?

   • ATo generate a global routing prefix from a MAC address
   • BTo generate a 48-bit MAC address from a 64-bit IPv6 address
   • CTo generate a 64-bit interface identifier from a 48-bit MAC address
   • DTo generate a multicast address from a MAC address

   A company is merging with another company. Both companies currently use unique local addresses (ULAs) for their internal networks. After the merger, they need to interconnect their networks. They discover that both companies have chosen the same ULA prefix (FD00::/8). What is the best course of action?

   • ARenumber one company's entire network to a different ULA prefix to avoid routing conflicts.
   • BUse network address translation (NAT) to translate between the two ULA prefixes.
   • CUse global unicast addresses for both companies and disable ULA.
   • DUse link-local addresses for inter-company communication.
