A network administrator notices the above line within the show ip route output of RTA. Given this information, which statement is true?
RTA is configured to manually summarize the 2.1.0.0 network.*
RTA automatically inserted this summary when the command network 2.1.0.0 was entered in router mode.
RTA learned network 2.1.0.0 from another redistributed protocol.
RTA learned this summary route from an EIGRP neighbor.

What action does an EIGRP router take to find a feasible successor for a network?
It examines the routing and topology tables for a feasible successor.
It transitions from passive to active state for that network and queries its neighbors.*
It examines the routing and neighbor tables for a feasible successor.

Which interface configuration command will affect the EIGRP metric calculation?
Router(config-if)# metric 896
Router(config-if)# ip eigrp metric 896
Router(config-if)# load 896
Router(config-if)# bandwidth 896*

Assuming that EIGRP is enabled on both routers, what must be configured to ensure that Router A will be able to reach the 2.2.2.0/24 network?
Use the command no auto-summary to disable automatic summarization.*
Use the command ip address-summary to ensure that Router A recognizes the 2.2.2.0 network.
EIGRP supports VLSM and will automatically recognize the 2.2.2.0 network.
EIGRP does not support VLSM, therefore cannot be used with discontiguous networks.

Authentication will fail because the key numbers do not match.*
Authentication will fail because the key-strings do not match.
Authentication will succeed.

Given the configuration statements shown in the diagram and assuming that EIGRP has already been enabled for this network, which statement is true?
RTC will enter a route to 2.1.0.0/16, sourced from the null0 interface, into its route table.*
RTC will accept the 2.1.0.0/16 route and assign it an administrative distance of 90.
RTD will accept the 2.1.0.0/16 route and assign it an administrative distance of 5.
RTD will receive two routes, the summary route of 2.1.0.0/16 and the automatic classful route of 2.0.0.0/8.
