Router R1 has been configured with the commands rout er eigrp 9 and network 172.16.2.0 0.0.0.255, with no other current EIGRP configuration. R1's (working) Fa0/0 interface has been configured with IP address 172.16.2.2/26. R1 has found three EIGRP neighbors reachable via interface Fa0/0, including the rou ter with IP address 172.16.2.20. When the engineer attempts to add the neighbor 172.16.2.20 fa0/0 command in EIGRP configuration mode.
Which of the following occurs？（）
A.Fa0/0 fails
B.The command is rejecteD
C.The existing three neighbors fail
D.The neighborship with 172.16.2.20 fails and then reestablishes
E.None of the other answers is correct

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？（）
A. debug eigrp packet
B. show key chain
C. show ip eigrp neighbor failure
D. show clock
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. 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.
