If the primary path goes down, what will EIGRP use to reach a destination?

Refer to the exhibit. Which one statement is true?

Which configuration command is used to enable EIGRPunequal-cost path load balancing?

A network administrator is troubleshooting an EIGRPconnection between RouterA, IP
address 10.1.2.1, and RouterB, IP address 10.1.2.2.
Given the debug output on RouterA, which two statements are true?

What administrative distance is given to EIGRP summary routes?

Which of the following settings could prevent two potential EIGRP neighbors from becoming
neighbors? (Choose two answers.)

An engineer has added the following configuration snippet to an implementation planning
document. The configuration will be added to RouterR1, 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 other. 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 fred
key 3
key-string whehew
interface fa0/0
ip authentication key-chain eigrp 9 fred

Which of the following are methods EIGRP uses to initially populate (seed) its EIGRP
topology table, before learning topology data from neighbors? (Choose two.)

Refer to the exhibit. Network administrators have set up a hub and spoke topology with
redundant connections using EIGRP. However, they are concerned that a network outage
between Router R1 and Router R2 will cause traffic from the 10.1.1.x network to the
10.1.2.x network to traverse the remote office links and overwhelm them. What command
should be used to configure the spoke routers as EIGRP stub routers that will not advertise
connected networks, static routes, or summary addresses?

Refer to the network topology diagram shown in the exhibit. The routing table of R3 contains
all the proper OSPF routes except the 10.4.4.0/24 OSPF route. Which show command on
R3 will be the most useful to determine the cause of this problem and why?
