Question

A healthcare company applies a Bedrock Guardrail to their patient-facing chatbot. The guardrail is configured with: a denied topic for 'medical diagnosis', a content filter set to HIGH for violence, a sensitive information filter that masks patient names, and a contextual grounding check with a threshold of 0.8. A compliance auditor asks how Bedrock evaluates a single user prompt against these policies and what determines the final outcome returned to the application. Which statement accurately describes the guardrail's evaluation behavior?

Accepted Answer

All configured policies are evaluated independently on the input; if ANY policy triggers a blocking action, the guardrail intervenes and returns the configured blocked message, and the trace indicates which policy fired.

Answer

Policies are evaluated sequentially in a fixed priority order, and evaluation stops at the first policy that passes without triggering, allowing the request through.

Answer

Only the highest-severity policy (the HIGH violence content filter) is evaluated; the other policies are ignored unless the content filter passes.

Answer

Contextual grounding is evaluated on the input prompt, and if the grounding score exceeds 0.8 the other policies are automatically skipped for that request.
