The following questions are designed to test your knowledge of common application design considerations, and they sometimes build on knowledge found elsewhere in the book. You might find that each question has more than one possible answer. The answers provided in Appendix B are intended to reinforce concepts that you can apply in your own networking environment.
Does implementing antivirus on your mail servers eliminate the need for AV on your hosts?
Before deploying AV for e-mail servers, what other action can provide at least as much benefit as network AV at a far lower cost?
If you are providing DNS recommendations to a very small organization with only a small public web and e-mail presence hosted at its ISP, which DNS design from this chapter would you recommend?
When should you use HTTP as opposed to HTTPS? Does it impact the security design?
