I have a helpful tip for those of you in your final weeks of review for you Cisco test.
Creating a baseline start up configuration is helpful to speed up your labs and allow you to work on learning the specific technology at hand and spend less time doing introductory setup tasks.(Unless you need to learn those tasks for the test!)
Here are the following things that should stay in your startup config:
mgmt ip address
simple enable secret password
simple console and VTY logins
service password encryption
no ip domain lookup
Once you get these items entered, do a copy running-config startup-config.
Now your start-up config is set. Now when you power off or reload your equipment, you will have this waiting and ready for the the next lab. Just remember not run the command again during your labs!
