Description: A quick reference of all commands in one compact, portable resource. This popular format lists all of the commands that are required to pass the objectives of the exams. Throughout the books there will be Configuration Examples given to the reader, which will have a diagram of a network, and then command outputs, showing all of the commands needed to create the network, showing what commands to use, where to use them, and a brief description of why we are using the commands.
