This is a technical question. Interviewers ask technical questions to determine how well you understand the concepts, technologies, and terms involved in your work. The best way to respond to a technical question is directly and briefly defining the concept and then describing how it is used in your profession. Anticipate that the interviewer will ask a follow-up question to dig deeper into the topic or explore it in more detail.

William Swansen

"Subnetting is the process of dividing the network into smaller segments. This adds additional security to the network by enabling you to better control the flow of traffic. It also enhances your ability to identify threats, points of entry, and to address the issues quicker and more directly."
