Exam Essentials

Understand the difference between a physical network diagram and a logical network diagram. A physical diagram shows all of the physical connections and devices and in many cases the cables or connections between the devices. It’s a very detail-oriented view of the hardware on your network. A logical network diagram takes a higher-level view, such as your subnets and which protocols those subnets use to communicate with each other.

Understand the difference between policies, procedures, and regulations. A policy is created to give users guidance as to what is acceptable behavior on the network. Policies also help resolve problems before they begin by specifying who has access to what resources and how configurations should be managed. Procedures are steps to be taken when an event occurs on the network, such as what to do when a user is fired or how to respond to a natural disaster. Regulations are imposed on your organization; you are required to follow them, and if you don’t, you may be subject to punitive actions.
