Which one of the following is the subnet mask equivalent of /27?

A. 255.255.255.192

B. 255.255.255.224

C. 255.255.255.240

D. 255.255.255.248

Solution

subnet mask equivalent of /27?

/27 : means 27 bit for network address

TO calculate subnet mask : put 27 1\'s followed by remaning number of zeros

11111111:11111111:11111111:11100000
= 255.255.255.240
