A regional bank is planning a network refresh. The CIO states that the primary goal is to reduce the time-to-market for new digital services, while the CFO emphasizes minimizing capital expenditure. The network team proposes starting with a detailed inventory of existing switches and routers. According to the top-down network design methodology, what should the design team do first?

Document the business goals and constraints, then derive technical requirements from them.

Conduct a site survey to determine cabling and power constraints.

Create a detailed physical diagram of the current network to identify upgrade paths.

Select the latest switching and routing hardware that fits the budget.

A logistics company has completed a logical design for its new warehouse network. Before purchasing equipment, the design team wants to validate that the design meets the performance requirements. What is the most appropriate next step?

Proceed directly to purchasing equipment based on the logical design.

Build a prototype in a lab and run tests to measure performance and reliability.

Document the design and archive it without testing.

Ask the vendor for a quote based on the logical design.

A financial services firm is designing a new network. The logical design includes a redundant core with two routers and a collapsed core/distribution layer. The physical design must now select specific router models. Which consideration is most important when choosing the routers?

The warranty period offered by the vendor

The color and form factor of the chassis

The number of available slots for interface modules

Which activity is part of the design optimization process?

Defining the IP addressing scheme

Adjusting the design to improve performance based on test results

Selecting the physical cabling type

A business requirement states that the network must continue operating during a fiber cut. Which technical requirement does this translate to?

Security to prevent unauthorized access

High performance with low latency

Scalability to accommodate growth

High availability with redundant paths
