Q14 / 25

2. BImprove accessible input guidance, add progress information, and provide explanation plus feedback controls.
3. CAdd performance metrics before use and prevent challenges to completed outputs.
4. DAdd a risk rating after output but keep input inaccessible and processing opaque.

Q15 / 25

A team runs an AI application on Amazon EC2 and installs its own inference software. It must assign responsibility for operating-system patches and application updates. Who owns both tasks?

1. AThe customer, because both layers run inside its EC2 workload
2. BAWS, because EC2 transfers guest software maintenance to the provider
3. CThe external auditor, because patching is a compliance control
4. DAWS for the application and the customer for physical infrastructure

Q16 / 25

Why can adding unrelated material weaken a request context?

1. AIt permanently replaces the model's learned parameters
2. BIt makes retrieval unnecessary for every application task

Q25 / 25

An organization must process model requests inside the EU and uses a Service Control Policy that permits only its source Region. Calls made through the EU geographic inference profile start to fail. What explains the failure and resolves it?

1. AThe data no longer resides in the source Region, so it has to be replicated to every destination Region before calls succeed
2. BEncryption in transit is blocking the routed requests, so it has to be disabled between the source and destination Regions
3. CThe profile can route to other destination Regions, so the policy must allow them or carry an inference-profile exception
4. DGeographic profiles send data outside the EU, so the workload has to stop using cross-Region inference to stay compliant
