You have been brought in to troubleshoot an EIGRP network. A network engineer has made
configuration changes to the network rendering some locations unreachable. You are to locate the
problem and suggest solution to resolve the issue.
R5 has become partially isolated from the remainder of the network. R5 can reach devices on
directly connected networks but nothing else. What is causing the problem?
A.
An outbound distribute list in R3
B.
Inbound distribute lists in R5
C.
An outbound distribute list in R6
D.
Incorrect EIGRP routing process ID in R5

Here we see that distribute list 3 has been applied to EIGRP on router R%, but access-list 3
contains only deny statements so this will effectively block all routing advertisements from its two
EIGRP neighbors, thus isolating R5 from the rest of the EIGRP network:
