Applied Knowledge Questions

The following questions are designed to test your knowledge of supporting-technology design considerations and sometimes build on knowledge found elsewhere in the book. You might find that a 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.
