There is a request from the networking team in your organization to create the below VPC in AWS
172.168.128.128/28
How many subnets would be allowed with this configuration?

Answer options:

A.1
B.16
C.20
D.24

Answer – A
Smallest allowable CIDR range for a VPC is /28 so it cannot be subnetted any further.
With a AWS VPC would result in only 1 Subnet and 11 available hosts (16 - 5 reserved)
