50. A company wants to automate customer-support requests using AI while maintaining human oversight for complex cases. Which architecture is most appropriate?

  1. Receive request → classify intent → retrieve relevant knowledge → generate a response or recommended action → validate against guardrails → automatically resolve suitable cases or escalate complex/high-risk cases to a human
  2. Allow the AI to execute every action without permissions, validation, or human review
  3. Use an LLM only to generate random responses without accessing customer information
  4. Train a new model for every support request and deploy it immediately

Answer: A) Receive request → classify intent → retrieve relevant knowledge → generate a response or recommended action → validate against guardrails → automatically resolve suitable cases or escalate complex/high-risk cases to a human

Explanation:

This architecture combines deterministic workflow control with AI capabilities such as classification, retrieval, and generation. Guardrails and human escalation provide additional control for uncertain or high-impact cases. Modern agent architectures similarly combine models, tools, instructions, orchestration, and approval mechanisms to execute multi-step work.
