You have a subnet mask of 255.255.240.0. What would the CIDR notation be?
A.
/16
B.
/20
C.
/24
D.
/28
Explanation:
Defining Classless Inter-Domain Routing (CIDR)One example of CIDR would be the IP network number 192.168.0.0/16. The /16 means that the subnet mask has 16 masked bits (or 1s), making
255.255.0.0. Usually, that would be a default Class B subnet mask, but because we are using it with what used to be a Class C network number, the whole address
becomes classless.
