What is the role of the DMZ in network architecture? How do you enforce relational integrity in database design?

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."
