Question: 1
You are a network administrator of the Company company. Examine the Company network
topology carefully. EIGRP has been configured on this network. P4R1, P4R2 and P4R3 are
connected with each other. When the link between P4R1 and P4R3 is down, what would P4R4
receive from P4R3?
A. P4R4 would not receive any updates or queries, since P4R3 would simply move to the path
through P4R2.
B. P4R4 would receive an update noting P4R3's higher cost to reach 172.30.1.0/24.
C. P4R4 would receive a query, since P4R3 would mark 172.30.1.0/24 as active when the link
between P4R1 and P4R4 failed
D. P4R4 would not receive any packets, since P4R3 is not using the link to P4R1 to reach
172.30.1.0/24.

A. 172.30.1.0/24 and 10.1.2.0/24; EIGRP only performs autosummarization at the edge between
two major networks
B. 172.30.0.0/8 and 10.0.0.0/8
C. 172.30.0.0/16 and 10.1.2.0/24; P4S-R2 will perform autosummarization, although P4S-R1 will
not
