Guide: WAN Connection Types
A Wide Area Network (WAN) is a telecommunications network that extends over a large geographical area. It can connect schools, businesses, and individuals located in different cities, states, or even countries. A WAN can be publicly accessible or strictly for private use.
Why is it important?
Understanding WAN Connection Types is vital because it helps in designing, implementing, and troubleshooting network systems efficiently and effectively. It is a critical component of the CompTIA Network+ certification and IT networking in general.
How it works?
There are several types of WAN connections including leased lines, circuit switching, packet switching, and cell relay. These different types have unique characteristics and operate in different ways. For example, a leased line is a permanent connection between two points which provides a secure and reliable data connection. On the other hand, packet switching allows data to be broken into packets and sent over a network to be reassembled at the destination.
Answering Exam Questions:
To answer questions about WAN Connection Types, make sure you understand the characteristics of each type and can identify the appropriate type based on a given scenario. Remember to note the advantages and disadvantages of each connection type.
Exam Tips:
1. Understand each WAN Connection Type in depth. Even if the exam question does not directly ask for a definition, you may need to utilize this knowledge to answer scenario-based questions.
2. Focus on application questions. Be able to identify the most effective WAN connection type given different business needs and situations.
3. Practice with sample questions. The more familiar you are with the format of the exam questions, the more comfortable you will be during the actual exam.

WAN Connection Types practice test
WAN Connection Types refer to the variety of ways a WAN can be established or accessed. This impacts the quality, speed, and cost of the network. Some common WAN connection types include: 1) Leased Lines: dedicated, point-to-point communication lines with guaranteed bandwidth and service quality. They are expensive but deliver excellent performance. 2) Circuit Switching: establishes a temporary connection between devices, with the dedicated path for the entire conversation. Example technology: PSTN. 3) Packet Switching: data is sent in smaller units called packets and reassembled at the destination. Example technologies: Frame Relay and ATM. 4) Broadband: a high-speed internet connection using DSL, cable, or fiber optic technology. Broadband connections are typically faster and more maintained than dial-up connections. 5) Satellite: uses satellites to provide communication between remote areas. Satellite connections often suffer from high latency and slower speeds. Choosing the appropriate WAN connection type is essential based on factors like cost, performance, and location.
