Your company is designing its public network. The network will use an IPv4 range of 131.107.40.0/22. The network must be configured as shown in the following exhibit.
You need to configure subnets for each segment.
Which network addresses should you assign?
A.
Segment A: 131.107.40.0/23
Segment B: 131.107.42.0/24
Segment C: 131.107.43.0/25
Segment D: 131.107.43.128/27
B.
Segment A: 131.107.40.0/25
Segment B: 131.107.40.128/26
Segment C: 131.107.43.192/27
Segment D: 131.107.43.224/30
C.
Segment A: 131.107.40.0/23
Segment B: 131.107.41.0/24
Segment C: 131.107.41.128/25
Segment D: 131.107.43.0/27
D.
Segment A: 131.107.40.128/23
Segment B: 131.107.43.0/24
Segment C: 131.107.44.0/25
Segment D: 131.107.44.128/27
Explanation:
1: The corresponding CIDR notation prefix lenth is /22.
2: The next myltiple of 8 that is greater than 22 is 24. Octet 3 is interesting.
3: 24-22 = 2, so the incremental is 2^2 =4.
4: The increments in the third octer are 0,4,8,12,16,20,24,28,32,36,40,44,46, and so on.
