   A network engineer needs to send a video stream to a group of 50 hosts that are all interested in receiving the stream. The hosts are spread across multiple subnets in the same enterprise network. The engineer wants to minimize bandwidth usage by sending only one copy of the packet that will be replicated only to the hosts that have joined the group. Which IPv6 address type should be used as the destination address?

   • ALink-local address
   • BMulticast address (FF00::/8)
   • CGlobal unicast address
   • DAnycast address

   A network administrator is troubleshooting an IPv6 connectivity issue between two routers connected via a point-to-point link. The routers can ping each other's global unicast addresses, but they cannot ping each other's link-local addresses. The administrator suspects a problem with the Modified EUI-64 generated link-local addresses. What is the most likely cause?

   • AThe routers have duplicate link-local addresses because they have the same MAC address.
   • BThe neighbor cache entries are missing or stale, preventing the routers from resolving each other's link-local addresses.
   • CThe link-local addresses are not in the same /64 subnet as the global unicast addresses.
   • DThe link-local addresses are on different subnets because the interface IDs were generated from different MAC addresses.

   A company wants to deploy IPv6 internally without obtaining a globally unique prefix from their ISP. They need addresses that are routable within their private network but will not be forwarded on the public internet. Which address type should they use?

   • ALink-local address
   • BMulticast address
   • CGlobal unicast address
   • DUnique local address (ULA)

   A network administrator is designing an IPv6 addressing scheme for a large enterprise. The administrator needs to support the following requirements: (1) internal servers that must be reachable from the internet, (2) internal printers that should not be reachable from the internet, and (3) a group of workstations that need to receive software updates simultaneously. Which address types should be used? (Select all that apply.)

   • AAnycast for the internal printers
   • BLink-local for the internal servers
   • CMulticast for the group of workstations
   • DUnique local for the internal printers
   • EGlobal unicast for the internal servers

   A small business is assigned an IPv6 global unicast prefix 2001:db8:abcd::/48 by its ISP. The network administrator wants to create multiple subnets within the /48 prefix for different departments. The administrator also wants to ensure that devices can automatically obtain their IPv6 addresses without a DHCPv6 server. Which addressing approach should be used?

   • AUse SLAAC with the /48 prefix and let devices generate their own interface identifiers.
   • BUse link-local addresses for all devices.
   • CUse DHCPv6 to assign addresses from the /48 prefix.
   • DUse unique local addresses (FC00::/7) for all devices.
