Refer to the exhibit.
What is the most appropriate summarization for these routes?
A.
10.0.0.0 /21
B.
10.0.0.0 /22
C.
10.0.0.0 /23
D.
10.0.0.0 /24
Explanation:
The 10.0.0.0/22 subnet mask will include the 10.0.0.0, 10.0.1.0, 10.0.2.0, and 10.0.3.0
networks, and only those four networks.
Thought this might be useful:
Look for the octet where there is a change
10.0.1 => 001
x.x.2 => 010
x.x.3 => 011
so 10.0.0.0 /(16+6 = 22)
0
