Longer answers improve some quality scores but increase delay.
Select a configuration for service requirements.
Choose two appropriate practices.
Hint 1: Focus on the requirement Compare tail latency and quality together, and define a safe alternate route when the service cannot meet its objectives.
Hint 2: Key terms Review quality, latency, and fallback trade-offs.
Quality-latency trade-offA relationship in which additional processing can improve output while increasing time or cost.
p95 latencyThe response time below which 95 percent of measured requests complete.
SLOA measurable service target for latency, availability, quality, safety, or another outcome.
FallbackAn alternate model, shorter response, delayed job, or human route used when a target is not met. × Incorrect Compare quality, p95 latency, and token cost on the same set and use a safety fallback when high-impact cases fail requirements.
Detailed explanation A Correct Compare quality, p95 latency, and token cost under the same test conditions
Configurations can be compared fairly.
B Incorrect Use mean latency to claim a p95 target
Tail latency can remain too high.
C Incorrect Ignore latency and cost for a small quality increase
User experience and SLO may fail.
D Correct Evaluate safety cases separately and fall back when a threshold is missed
Speed improvements must not remove safety.

Key points Notes Environment: AWS公式AIF-C01試験ガイドとAWS公式ドキュメントの確認 Compare the definition with the AIF-C01 objective and the service documentation before applying it. Keep the concept separate from a particular answer choice or implementation step. Foundation review Quality-latency trade-off A relationship in which additional processing can improve output while increasing time or cost.
p95 latency The response time below which 95 percent of measured requests complete.
