Routers R1 and R2, currently EIGRP neighbors over their Fa0/0 interfaces (respectively),both use EIGRP authentication. Tuesday at 8 p.m. the neighborship fails.
Which of the following wo uld not be useful when investigating whether authenticationhad anything to do with the failure？（）

Routers R1 and R2 are EIGRP neighbors using their Fa0/0 interfaces, respectively. An engineer adds the ip hello - interval eigrp 9 6 command to R1's Fa0/0 configuration.
Which of the following is true regarding the results from this c hange？（）
A.The show ip eigrp neighbors command on R1 lists the revised Hello timer
B.The show ip eigrp interfaces command on R1 lists the revised Hello timer
C.The R1 - R2 neighborship fails due to Hello timer mismatcH
D.The show ip eigrp interfaces detail command on R1 lists the revised Hello timer
Router R1 has working interfaces S0/0, S0/1, and S0/2, with IP address/prefix combinations of 10.10.10.1/24, 10.10.11.2/24, and 10.10.12.3/22. R1's configuration includes the command s router eigrp 9 and network 10.0.0.0. The show ip eigrp interfaces command lists S0/0 and S0/1 in the command output, but not S0/2.
Which answer gives the reason for the omission？（）
A. R1 has EIGRP neighbors reachable via S0/0 and S0/1, but not via S0/2, so it is not included.
B. S0/2 may currently be in a state other than up/up.
C. The network 10.0.0.0 command requires the use of mask 255.0.0.0 due to EIGRP being classful by default.
D. S0/2 may be configured as a passive inter face.
A router has been configured with the commands router eigrp 9 and network 72.16.1.0 0.0.0.255. No other EIGRP - related commands have been configured. The nswers list the IP addresses that could be assigned to this router's Fa0/0 interface.
Which answers list an IP address/prefix length that would cause the router to enable IGRP on Fa0/0?（）
A. 172.16.0.1/23
B. 172.16.1.1/26
C. 172.16.1.1/24
D. 172 .16.0.255/23
E. None of the other answers is correct.
Refer to the exhibit. Which two statements are true?（）
A. Router R1 will advertise connected and summary routes only.
B. The eigrp stub command will automatically enable summarization of routes on R2.
C. Router R1 is configured as a receive - only neighbor and will not send any connected, static, or summary routes.
D. The eigrp stub command prevents all routes except a default route from being advertised to R1.
E. The eigrp stub command prevents queries from being sent from R2 to R1.
F. Router R1 will advert ise connected and static routes. The sending of summary routes will not be permitted.
Refer to the exhibit. Routers R1 and R2 are running EIGRP and have converged. On the basis of the information that is presented, which statement is true? （）
A. Both outgoing and incoming routing updates on R1 will be permitted because the d istribute - list 20 out Serial0/0 command cannot be used with association with the outgoing interface.
B. All incoming routing updates from R2 will be suppressed, but the outgoing updates will continue to be sent.
C. Both outgoing and incoming routing up dates on R1 will be stopped because of the passive - interface Serial0/0 configuration statement.
D. All outgoing routing updates from router R1 to router R2 will be suppressed, but the inbound updates will continue to be received.
