6. How do you typically go about estimating network traffic?
Why the Interviewer Asks This Question
Managing and optimizing network traffic is a vital function of a computer network architect. Designing networks that will handle both normal traffic loads and traffic peaks requires an in-depth understanding of how to estimate the organization's current bandwidth needs. Interviewers will ask you about this to confirm that you can architect networks that will meet their organization's needs and are economical to build and operate.

Answer Example
"Estimating an organization's network traffic is as much an art as it is science. It requires understanding the organization's operations and events or issues which will cause increases or decreases in network traffic. For example, if the organization conducts e-commerce, there may be seasonal spikes in its network traffic requirements. I try to design networks that are optimized for average network traffic but will also accommodate the occasional peaks or spikes. This requires measuring the organization's daily traffic and collaborating with the other business units to understand their projected growth and any events which will spike network traffic."
