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.

"A subnet mask is similar to an IP address. However, it is combined with the IP address to identify two characteristics of the node. These include the extended network address and the host address. The purpose of a subnet mask is to define the node's address so traffic can be routed to the node more efficiently. The subnet mask consists of 32 bits."
