A healthcare-scheduling agent produces about 2 million traces per day. The observability bill is growing fast, and the privacy officer objects that full prompts with patient details are kept for a year. Which TWO changes best balance diagnostic value, cost and compliance? (Select two.)

Answer: A and D — Keep every trace with an error, high cost, high latency or a flagged outcome, and sample routine successful traces / Redact or minimize patient identifiers at capture and keep full payloads only for sampled traces with shorter retention

Outcome-based sampling keeps the rare traces you need for diagnosis while cutting volume (a), and redaction at capture with tiered, shorter-retention payload storage addresses both cost and data minimization (d). (b) discards most errors and outliers along with routine traffic. (c) removes visibility into model and tool behaviour that the scheduling system's audit log doesn't record.
