2A router receives an Ethernet frame that holds an IPv6 packet. The router then makes a decision to route the packet out a serial link. Which of the following statements is true about how a router forwards an IPv6 packet?
- Aa. The router discards the Ethernet data-link header and trailer of the received frame.
- Bb. The router makes the forwarding decision based on the packet’s source IPv6 address.
- Cc. The router keeps the Ethernet header, encapsulating the entire frame inside a new IPv6 packet before sending it over the serial link.
- Dd. The router uses the IPv4 routing table when choosing where to forward the packet.

14Router R1 currently supports IPv4, routing packets in and out all its interfaces. R1’s configuration needs to be migrated to support dual-stack operation, routing both IPv4 and IPv6. Which of the following tasks must be performed before the router can also support routing IPv6 packets? (Choose two answers.)
- Aa. Enable IPv6 on each interface using an ipv6 address interface subcommand.
- Bb. Enable support for both versions with the ip versions 4 6 global command.
- Cc. Additionally enable IPv6 routing using the ipv6 unicast-routing global command.
- Dd. Migrate to dual-stack routing using the ip routing dual-stack global command.
15Router R1 has an interface named Gigabit Ethernet 0/1, whose MAC address has been set to 0200.0001.000A.
