Imagine an enterprise network, an example of campus network, which is composed of 4 buildings interconnected. Each building has its own LAN and the LANs are interconnected via 4 routers. Also, there is a WAN link that provides Internet access through an ISP. Answer the following questions.

-The ISP wants to use a supernet address in its routing table to summarize the client's subnets. Which is NOT a possible supernet address? Not all subnets in the Figure are given a subnet address. To find a solution, therefore, only count subnet addresses provided.
A) 100.20.0.0/16
B) 100.0.0.0/8
C) 100.20.128.0/17
D) 100.20.196.0/18
E) Both C and D

A supernet address is created by combining multiple subnets into a larger network address, which is used for route summarization. Options C and D cannot be correct supernet addresses because they specify subnet ranges that are too specific and do not align with the broader aggregation needed for effective summarization. Supernetting typically involves extending the network portion of the address and reducing the host portion, which is not reflected in options C and D as they point to more specific (smaller) portions of the network.
