cument. The configuration will be added to Router R1, whose Fa0/0 interface connects to a LAN to which Routers R2 and R3 also connect. R2 and R3 are already EIGRP neighbors with each of her. Assuming the snippet shows all commands on R1 related to EIGRP authentication, which answer lists an appropriate comment to be made during the implementation plan peer review？（）key chain fredkey 3key - string whehewinterface fa0/0ip authenticat ion key - chain eigrp 9 fred

A.The configuration is missing one authentication - related configuration command

B.The configuration is missing two authentication - related configuration commands

C.Authentication type 9 is not supported; type 5 should be u sed insteaD

D.The key numbers must begin with key 1, so change the key 3 command to key 1

terfaces. R1 learns a route from R2 using EIGRP f or IPv6. That route lists F0/0 as the outgoing interface with R2 as the next hop. The configuration excerpt shows all relevant configuration on R2‘s F0/0 interface. Which of the following is true about R1‘s route？（）interface f0/0mac - address 1111.1111.1 111ipv6 address 2000::/64 eui - 64ipv6 address 2001::1/64
