Question

"Which subnet mask below is equivalent to /24 in CIDR notation?

a. /16
b. /20
c. /24
d. /28"

Answer 1

The subnet mask equivalent to /24 in CIDR notation is represented by option c. /24, which is 255.255.255.0 in decimal format.

Step-by-step explanation:

The /24 in CIDR notation is equivalent to a subnet mask with 24 bits set to 1 in the mask, which aligns with option c. /24. This means the first 24 bits of the IP address are used to identify the network, and the remaining 8 bits are used to identify hosts within that network. In the decimal format, this is expressed as 255.255.255.0, where each 255 represents eight consecutive 1s and the 0 represents eight consecutive 0s.
