Question

What subnet mask is represented by the slash notation /20?

a) /8
b) /16
c) /24
d) /20

Answer 1

The subnet mask represented by the slash notation /20 is /20.

Step-by-step explanation:

The subnet mask represented by the slash notation /20 is option d) /20.

The slash notation accompanies an IP address and represents the number of network bits in the address. In this case, /20 means that the first 20 bits of the IP address represent the network portion, and the last 12 bits represent the host portion. The subnet mask is a binary value consisting of 32 bits, with the first 20 bits set to '1' to represent the network portion and the remaining 12 bits set to '0' to represent the host portion.
