Question 550
The telecommunications project is considering Amazon Bedrock Agents to coordinate foundation-model instructions with knowledge and action groups. Which limitation could invalidate an overly broad claim about it?
- Tool permissions and confirmation gates are necessary for consequential actions.
- Runtime hosting does not by itself define business permissions or safe tool policies.
- Remembered content still needs privacy controls, lifecycle rules and verification.
- An agent does not grant itself permission to operate external systems.
Explanation
Correct Answer
D:A telecommunications rollout should account for this boundary: an agent does not grant itself permission to operate external systems. The chosen approach works because Bedrock Agents can orchestrate task steps that use configured knowledge and actions, but it is not evidence that every circumstance arising when trying to coordinate foundation-model instructions with knowledge and action groups has been addressed.
