"A DMZ is a security strategy that helps keep unwanted traffic out if the client's private network. It is analogous to creating a small isolated network positioned between the Internet and the private network. While it is not 100% effective, it does provide the ICT administrators with one more line of defense, and additional time to detect malicious traffic trying to penetrate the network."

Another example of a hybrid operational and technical question. You are first being asked to define an ICT term, followed by an explanation of how it is used in the work you perform. The best way to address questions like this is to provide the definition and then give an example of how you would use the technology. Anticipate follow-up questions from the interviewer since this is very specific and topical.

"DMZ, which is short for DeMilitarized Zone, are buffer zones set up between public and private networks. The purpose of a DMZ is to maintain the security of the network and filter out any unwanted traffic. The traffic is screened using a firewall or another security appliance before it is allowed into the private network."
