A company has a Frame Relay WAN with one central-site router and 100 branch office
routers. A partial mesh of PVCs exists: one PVC between the central site and each of the
100 branch routers. Which of the following could be true about the number of EIGRP
neighborships?

A network design shows that R1 has four different possible paths from itself to the Data
Center subnets. Which one of the following commands is most likely to show you all the
possible next-hop IP addresses for these four possible routes?

Router R1 lists 4 routes for subnet 10.1.1.0/24 in the output of the show ip eigrp
topology all-links command. The variance 200 command is configured, but no other
related commands are configured. Which of the following rules are true regarding
R1’s decision of what routes to add to the IP routing table? Note that RD refers to reported
distance and FD to feasible distancE.

Router R1 has been configured for EIGRP. The configuration also includes an ACL with one
line–access-list 1 permit 10.100.32.0 0.0.15.255–and the EIGRP configuration includes the
distribute-list 1 in command. Which of the following routes could not be displayed in the
output of the show ip eigrp topology command as a result?

seq 5 deny 10.1.2.0/24 ge 25 le 27
seq 15 deny 10.2.0.0/16 ge 30 le 30
seq 20 permit 0.0.0.0/0

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?
