Tables To Remember

The Purpose

This page gives a listing of the tables that are either necessary or worthwhile to remember for the CCNA exam. The page does not list the tables themselves, but is a means of reference for testing purposes. Using this list, one is able to keep in mind what one should remember for the exam. The approach to use with this list is to take each individual table, and see if one can memorize the details of the table without aid. The aim is to be able to memorize all the tables listed here, in preparation for the exam.
