AIF-C01 Practice Question: A developer is using the Amazon Bedrock…

Correct answer & explanation

The correct options are B, D, and E. Option B is required because InvokeModelWithResponseStream is the specific Bedrock API operation that returns a stream of response chunks (via the responseStream event stream) rather than a single blocking response, which is exactly what the developer needs to process partial results as they arrive. Option D is required because the streaming response is delivered as an event stream of typed events such as chunk and modelStreamErrorException, so the client must iterate over the stream and decode each chunk's bytes (for example, base64-decoded JSON delta text) to consume partial output incrementally. Option E is required because streaming responses can terminate with in-stream error events and the connection can drop mid-stream, so the implementation must handle these exceptions and read the stream to completion to avoid truncated output. Options A and C are not part of the necessary streaming implementation: they describe non-streaming or unrelated behaviors and are not marked correct.
