Lab 5.1.2.4 Designing and Creating a Redundant Network
Step 1: Determine the minimum number of links to meet the requirements
- Identify the two links to meet requirement 1.
- Determine the cost of those two links.
- Identify the required links to meet requirement 2, 3, and 4.
- Determine if the design is within budget.
Step 2: Implement the design
- Using Packet Tracer, create the network including the redundant links specified in Step 1.
Step 3: Verify the design
- Do three paths between the east and west coast operations exist?
- Does each site have at least two links?
- Does each site on the east coast have two paths to the west coast?
- Does each site on the west coast have two paths to the east coast?
- Will one device failure affect multiple sites?
Reflection
- What network topology was implemented before adding redundancy? Jawaban: Extended Star
- What network topology is now implemented after adding redundancy? Jawaban: Partial Mesh
- What is an advantage to using the topology implemented after adding redundancy? Jawaban: redundancy minimizes the impact that the failure of a single piece of equipment has on the operation of the network.
- What is a disadvantage to using the topology implemented after redundancy was added? Jawaban: the increased cost of providing redundant links and equipment. Smaller companies may not be able to afford the cost.
- Why would a company, such as the one in this case, suddenly decide to implement the type of topology used in step b? Jawaban: In this case, the company lost 16 hours of production and $600,000 to the company. No company wants to lose sales or time that causes a loss in profit to their company.
