Can you describe what a subnet mask is and how you will use it in your job as a Cisco network engineer?

This is an example of a technical question. Technical questions typically ask you about terms, technologies, processes, or procedures used in the networking industry. The Cisco interviewer may ask you to define the term or to ask about its role. They may also ask you to compare and contrast two similar terms. When responding to a technical question, keep your answer succinct and speak in common terms as much as you can. Do not assume that the interviewer has a technical background.
