Even though you provided your resume to the interviewer, they may ask you questions about your experience. You should never assume that the interviewer has read your complete resume. Additionally, they may have read the resume but want to investigate your experience in more detail or explore your experience in areas not listed on the resume. Therefore, it is advisable to bring a copy of your resume, which you can reference to in the interview. You should also bring additional copies in case your interviewer has not seen it or did not bring it with them, or if there is a second interviewer. Don't become frustrated if they ask you questions that are already answered on the resume. Provide an answer to these questions as you would to any others.

"I have worked with proxy servers in my previous positions and consider them invaluable in protecting the data and users in a network. The function of a proxy server is to prevent unauthorized users from accessing the IP addresses of an internal network. It makes the computer network invisible to these users. They do this by masking the IP addresses users need to access the organization's internal websites and IP resources. Proxy servers also maintain a list of blacklisted websites, so an internal user is prevented from accessing these and possibly getting infected by viruses or other malicious software."

"A proxy server is a server that stands between the private enterprise internal network and the internet or public. This is a security measure to ensure that no one can enter into the private network directly from the world wide web or internet. The proxy server acts as an intermediary between a client residing on the outside."
