The correct answer to the following question will be "Length subnet masking".
Explanation:
The simplest terms of subnet trying to mask use a method called subnet masking of length (constant), whereby each subnet contains the same number of locations and constitutes a linear interpolation of the area of the interface offered by subnetting into several equivalent parts.
Using the VLSM, a network operator could use a long mask with very few servers on networks and a short mask with many hosts on subnetworks.
Therefore, Length subnet masking is the right answer.
