Which subnet does the host 192.168.19.36/27 belong?

Which subnet does the host 192.168.19.36/27 belong?
A . 192.168.19.0
B . 192.168.19.16
C . 192.168.19.64
D . 192.168.19.32

Answer: B

Explanation:

To find the subnet that the host 192.168.19.36/27 belongs to, we need to convert the IP address and the subnet mask to binary form and perform a logical AND operation. The /27 notation means that the subnet mask has 27 bits of ones and 5 bits of zeros. In decimal form, the subnet mask is 255.255.255.224.

The binary form of the IP address and the subnet mask are:

IP address: 11000000.10101000.00010011.00100100 Subnet mask:
