Explain the six steps of designing or modifying a WAN.

Step 1: Locate LANs:

• Establish the source and destination endpoints that will connect via the WAN.

Step 2: Analyze traffic:

• Find out what data traffic must be carried, its origin, its destination, bandwidth requirements, latency, and jitter tolerance.

Step 3: Plan the topology:

• Identify the various endpoints, geographic considerations, and requirement for availability.

Step 4: Estimate the required bandwidth:

• After considering the endpoints and the links chosen, you can estimate the necessary bandwidth.

Step 5: Choose the WAN technology:

• After you determine the bandwidth availability, you select suitable link technologies.

Step 6: Evaluate costs:

• Determine installation and operational costs for the WAN, and compare them with the business needs driving the WAN implementation.
