Working at the help desk, you receive a call and learn a user’s PC IP address and mask (10.55.66.77, mask 255.255.255.0). When thinking about this using classful logic, you determine the number of network (N), subnet (S), and host (H) bits. Which of the following is true in this case?a. N=12
b. S=12
c. H=8
d. S=8
e. N=24

Option C i.e., H=8.

Explanation:

The length for the component of the connection is often 8, 16, or 24, which is depending on for certain if there is classified A, B, or C, etc. N=8, as such an identifier in Category A. That 255.255.255.0 which is translated to prefix type is/24. Its amount of bits for the subnetwork is the correlation between both the size of the prefix that is 24 and N, so in the following case, S=16.
