Exam Essentials

Know your network topologies Know the names and descriptions of the topologies. Be aware of the difference between physical networks (what humans see) and logical networks (what the equipment sees)
Know the advantages and disadvantages of the topologies It is important to know what each topology brings to the table. Knowing the various characteristics of each topology comes in handy during troubleshooting
Understand the terms LAN and WAN You need to understand when you use a LAN and whe you use a WAN. a LAN is used to connect a group of hosts together, and a WAN is used to connect various LANs together

Written Lab

Answers can be found at the bottom of the page

What are the three basic LAN topologies

What is the term for a device that shares its resources with other network devices?
What network model draws a clear distinction between devices that share their resources and devices that do not?
Which network topology or connection type can be implemented with only two endpoints?
What device is generally implemented as a star topology?
What does MLPLS stand for?
What does WAN stand for?
Will a computer that shares no resources most likely be connected to the backbone or to a segment?
