Refer to the exhibit. The Lakeside Company has the internetwork in the exhibit. The administrator
would like to reduce the size of the routing table on the Central router. Which partial routing table
entry in the Central router represents a route summary that represents the LANs in Phoenix but no
additional subnets?
A.
10.0.0.0/28 is subnetted, 1 subnetsD10.4.4.0 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1
B.
10.0.0.0/22 is subnetted, 1 subnetsD10.4.0.0 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1
C.
10.0.0.0/28 is subnetted, 1 subnetsD10.2.0.0 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1
D.
10.0.0.0/30 is subnetted, 1 subnetsD 10.4.4.4 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1
E.
10.0.0.0/30 is subnetted, 1 subnetsD10.2.2.0 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1
F.
10.0.0.0/22 is subnetted, 1 subnetsD10.0.0.0 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1
Explanation:
The 10.4.0.0, 10.4.1.0, 10.4.2.0, and 10.4.3.0 can be correctly summarized by the single
10.4.0.0/22 network route as shown by option E.
