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 fred
key 3
key - string whehew

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

B. Duplicate EIGRP router IDs.
C. Mismatched Hold Timers.

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.

B.The command is rejecteD
C.The existing three neighbors fail
D.The neighborship with 172.16.2.20 fails and then reestablishes

A. debug eigrp packet
B. show key chain
C. show ip eigrp neighbor failure

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.

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.
A.When manual summarization is configured, the router immediately creates a route that points to null0 interface
B.Manual route summarization is configured in router configuration mode when the router is configured for EIGRP routing
C.Manual route summarization is configured on the interface
D.The ip summary - address eigrp command generates a default route with an administrative distance of 5
