Requirements to Architecture Mapping Questions
Bridges business and customer requirements to concrete architectural or non functional specifications. Candidates should extract throughput, concurrency, availability, latency, durability, security, compliance and budget constraints from scenarios and translate them into measurable goals such as requests per second targets, latency SLOs, durability levels, retention and encryption requirements. The topic includes creating a requirements matrix that directly informs component choices, capacity planning, and trade off justification.

Design a capacity plan template that maps from traffic forecasts to compute, networking, and caching capacity for a web API expected to grow 3x over 12 months. Include safety margins, autoscaling policies, and cost sensitivity parameters you would present to the business.

Behavioral: Describe a situation where you had to reconcile conflicting non-functional requirements from multiple stakeholders (e.g., security team requires strict encryption policies that impact latency). How did you prioritize, negotiate, and document the final decision?

Technical: Provide an example set of SLI definitions (3-5) for a public REST API that supports uploads and downloads. For each SLI provide the definition, collection method, and acceptable target (e.g., p95 latency < X ms, availability % over 30 days).

You are given a microservice that must handle 10k RPS with a p95 latency goal of 50ms. Without diving into code, list the architectural choices (compute type, autoscaling, networking, caching, load balancing) you would evaluate to meet throughput and latency goals. Prioritize the list and explain reasoning.

Problem: A system has both synchronous APIs and asynchronous batch jobs. The business requires a combined latency KPI where 95% of user-visible operations are completed within 2 seconds even if background jobs finish later. How do you map this into architecture choices for user-facing flows vs offline processing and what measurable hooks do you add to the requirements matrix?
