Quiz

An insurance company wants an LLM to draft claim decision letters. What is your architecture?

Interview prompt. A risk committee asks you to show that the guardrails on your customer-facing assistant work. You have a classifier on inputs and another on outputs, and a 99.7% pass rate in production. Convince me.

Your output safety classifier blocks 0.3% of responses in English and 6% in Portuguese and Turkish. Complaints arrive only from those two markets. The vendor confirms the same model version serves every region and reports no incident. Where do you look first?

A platform has a policy check that warns when a service lacks resource limits, readiness probes or an owner label. 140 of 200 services fail at least one check. The security team asks for it to become blocking next week. What happens if you do, and what would you do instead?

A platform team must ensure services meet security and observability requirements. Should that be a gate or a guardrail?

An interviewer gives you this - "Every service has to propagate W3C trace context. You have 200 services across 6 languages and no authority to mandate anything. Get me to full coverage, and tell me how you would know you got there." Walk through it.

When should a platform prevent an action automatically, and when should it require a human decision?

Your architecture review board is a three-week queue. Half the submissions are checking things like region, encryption and tagging. Redesign the process.

An architect is asked to design a system where the requirements, scale and business model are all still changing. How should they proceed?

An architect is asked to design something where the requirements are genuinely unclear and the stakeholders disagree about the goal. What is the productive approach?

An executive says "we need an AI strategy" and asks you to come back in two weeks. How do you handle the ambiguity?

The constraint that shaped your design - order records must stay inside the country - came from a conversation with the VP who commissioned the work. She leaves in month three. What happens to the design next and what should have been in place?
