R1 has correctly configured EIGRP to filter routes using a route map named question. The
configuration that follows shows the entire route map and related configuration. Which of the
following is true regarding the filtering action on prefix 10.10.10.0/24 in this case?
route-map question deny 10
match ip address 1
route-map question permit 20
match ip address prefix-list fred
!
access-list 1 deny 10.10.10.0 0.0.0.255
ip prefix-list fred permit 10.10.10.0/23 le 25

An engineer has typed four different single-line prefix lists in a word processor. The four
answers show the four different single-line 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?

An engineer plans to configure summary routes with the ip summary-address eigrp asn
prefix mask command. Which of the following, when added to such a command, would
create a summary that includes all four of the following subnets: 10.1.100.0/25,
10.1.101.96/27, 10.1.101.224/28, and 10.1.100.128.25?

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, and 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?

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 network 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 route for 172.16.0.0/16, instead of the individual subnets of class B
network 172.16.0.0?

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”. Which of the following is most likely to have caused this output to occur on
R1?

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 ip default-network. Which of the following is not a useful step with this style of
default route configuration?

A router has been configured with the commands router ospf 9, network 172.16.1.0
0.0.0.255 area 8, and network 172.16.0.0 0.0.255.255 area 9, in that order. No other OSPFrelated commands have been configured. The answers 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 put Fa0/0 into area 9? (Choose two.)

Which of the following is true about an OSPF area border router (ABR)?

Which of the following can either directly or indirectly identify all the interfaces for which both
1) OSPF has been enabled and 2) OSPF is not passive? (Choose two.)
