問題文
An exchange matching engine must accept several million orders per second and answer each one within a fraction of a millisecond. The team is deciding what its test approach should concentrate on for this environment. Which choice fits the environment described?
選択肢
- Measure the sustained order throughput because the matching engine must preserve execution determinism under extreme message volume.
- Measure the unified channel view because the customer journey must preserve shared account data under repeated channel switching.
- Measure the local failure containment because the payment service must prevent cascading downstream impact under partial dependency loss.
- Measure the annual premium accuracy because the policy engine must revalue compound interest under simulated clock movement.
