Command Reference to Check Your MemoryAlthough you should not necessarily memorize the information in the tables in this section,
this section does include a reference for the configuration and EXEC commands covered in
this chapter. Practically speaking, you should memorize the commands as a side effect of
reading the chapter and doing all the activities in this exam preparation section. To check to
see how well you have memorized the commands as a side effect of your other studies, coverthe left side of the table with a piece of paper, read the descriptions on the right side, and
see whether you remember the command.
