Question 1
A ticketing company expects brief holiday traffic peaks; finance demands a fixed annual spend while the product team needs a p95 checkout latency under 300 ms and no abandoned orders. Which assessment is best supported by the business and technical facts?
Explanation
Correct Answer
The architecture decision must reconcile burst capacity, latency and total cost rather than optimize a single bill. The specified situation supports this bounded diagnosis: Business and technical constraints together define the viable architectural trade-off. It is stronger than an inference based on one convenience metric. Compare peak traffic traces, checkout latency distributions and workload cost forecasts to the observed workload before choosing a final architecture.
Incorrect Answers
The cheapest annual instance quote is the only relevant architecture constraint. This interpretation substitutes a weaker proxy or adjacent explanation for the observed architectural failure. Business and technical constraints together define the viable architectural trade-off. The better-supported diagnosis is the architecture decision must reconcile burst capacity, latency and total cost rather than optimize a single bill. Review peak traffic traces, checkout latency distributions and workload cost forecasts before closing the analysis.
A fixed fleet is required because any cost variability is unacceptable to finance. This claim relies on a condition the scenario has not demonstrated and misses the controlling design constraint. Business and technical constraints together define the viable architectural trade-off. The better-supported diagnosis is the architecture decision must reconcile burst capacity, latency and total cost rather than optimize a single bill. Review peak traffic traces, checkout latency distributions and workload cost forecasts before closing the analysis.
Checkout abandonment can be excluded from the business case because it is not an infrastructure metric. The option asserts an unsupported conclusion about causation, access, consistency, or resilience. Business and technical constraints together define the viable architectural trade-off. The better-supported diagnosis is the architecture decision must reconcile burst capacity, latency and total cost rather than optimize a single bill. Review peak traffic traces, checkout latency distributions and workload cost forecasts before closing the analysis.
