Enterprise Router R1 connects an Enterprise to the Internet. R1 needs to create and advertise a default route into the Enterprise using EIGRP. The engineer creating the implementation plan has chosen to base this default route on the ip route command, rather than using i p default - network.
Which of the following is not a useful step with this style of default route configuration?（）
A. Create the default route on R1 using the ip route 0.0.0.0 0.0.0.0 outgoinginterface command.
B. Redistribute the statically configured defa ult route.
C. Disable auto - summary.
D. Configure the network 0.0.0.0 command.
E. Ensure R1 has no manually configured summary routes using the ip summary- address eigrp command.

Router R1 exists in an Enterprise that uses EIGRP as its routing protocol. The show ip route command output on router R1 lists the following phrase: "Gateway of last resort is 1.1.1.1 to network 2.0.0.0".
Whic h of the following is most likely to have caused this output to occur on R1?（）
A. R1 has been configured with an ip default- network 2.0.0.0 command.
B. R1 has been configured with an ip route 0.0.0.0 0.0.0.0 1.1.1.1 command.
C. R1 has been configured with an ip route 2.0.0.0 255.0.0.0 1.1.1.1 command.
D. Another router has been configured with an ip default - network 2.0.0.0 command.
E. Another router has been configured with an ip route 2.0.0.0 255.0.0.0 1.1.1.1 command.
In a lab, R1 connects to R2, which connects to R3. R1 and R2 each have several working interfaces, all assigned addresses in class A network 10.0.0.0. Router R3 has some working interfaces in class A net work 10.0.0.0, and others in class B network 172.16.0.0. The engineer experiments with the auto -summary command on R2 and R3, enabling and disabling the command in various combinations.
Which of the following combinations will result in R1 seeing a rout e for 172.16.0.0/16, instead of the individual subnets of class B network 172.16.0.0?（）
A. auto - summary on R2 and no auto - summary on R3
B. auto - summary on R2 and auto - summary on R3
C. no auto -summary on R2 and no auto- summary on R3
D. no auto - summary on R2 and auto - summary on R3
R1 has 5 working interfaces, with EIGRP neighbors existing off each interface. R1 has routes for subnets 10.1.1.0/24, 10.1.2.0/24, and 10.1.3.0/24, with EIGRP integer metrics of roughly 1 million, 2 million, a nd 3 million, respectively. An engineer then adds the ip summary - address eigrp 1 10.1.0.0 255.255.0.0 command to interface Fa0/0.
Which of the following is true?（）
A. R1 loses and then reestablishes neighborships with all neighbors.
B. R1 no longer advert ises 10.1.1.0/24 to neighbors connected to Fa0/0.
C. 1 advertises a 10.1.0.0/16 route out Fa0/0, with metric of around 3 million (largest metric of component subnets).
D. R1 advertises a 10.1.0.0/16 route out Fa0/0,with metric of around 2 million (med ian metric of component subnets).
A. 10.1.0.0 255.255.192.0
B. 10.1.64.0 255.255.192.0
C. 10.1.100.0 255.255.255.0
D. 10.1.98.0 255.255.252.0
An engineer has typed four different single - line prefix lists in a word processor. The four answers show the four different single -lin e prefix lists. The engineer then does a copy/paste of the configuration into a router.
Which of the lists could match a subnet whose prefix length is 27?（）
A. ip prefix - list fred permit 10.0.0.0/24 ge 16 le 28
B. ip prefix - list barney permit 10.0.0.0/24 le 28
C. ip prefix - list wilma permit 10.0.0.0/24 ge 25
D. ip prefix - list betty permit 10.0.0.0/24 ge 28
