An app must let users say 'book my usual flight and file the expense report' — the model should plan multi-step actions and call company APIs. Which Bedrock feature does this?
A.Knowledge Bases
KBs retrieve documents — they don't take actions.
B.Agents for Amazon Bedrock — orchestration with action groups calling Lambda/APIs
Correct. Agents = plan + invoke tools/APIs.
C.Guardrails
Guardrails filter content, no orchestration.
D.Provisioned Throughput
Throughput is a pricing/capacity mode, not a capability.
Why this answer
Bedrock Agents give the model orchestration: it breaks a request into steps and invokes action groups (Lambda functions / API schemas) to perform real actions. Knowledge Bases supply retrieval; Guardrails filter content — neither executes multi-step actions.
