Question 1

Question 2

Question 3

Explanation

AAA stands for Authentication, Authorization and Accounting.

+ Authentication: Specify who you are (usually via login username & password)
+ Authorization: Specify what actions you can do, what resource you can access
+ Accounting: Monitor what you do, how long you do it (can be used for billing and auditing)

An example of AAA is shown below:

+ Authentication: “I am a normal user. My username/password is user_tom/learnforever
+ Authorization: “user_tom can access LearnCCNA server via HTTP and FTP
+ Accounting: “user_tom accessed LearnCCNA server for 2 hours“. This user only uses “show” commands.

Question 4

Explanation

If neither the enable password command nor the enable secret command is configured, and if there is a line password configured for the console, the console line password serves as the enable password for all VTY sessions -> The “enable secret” will be used first if available, then “enable password” and line password.
