問題文
A pipeline must not lose any work item, must be able to inspect items that failed repeatedly, and must let the consumer pull items at its own pace. Which service fits, and what makes the other one less suitable?
選択肢
- Either service, because both deliver at least once and both can be configured with a dead-letter location, so the requirements are met in either case
- Event Grid, because its retry schedule spans a longer window than Service Bus redelivery and therefore gives a struggling consumer more chances to succeed
- Service Bus, because the consumer pulls under a lock and failed items land in a dead-letter queue, whereas Event Grid pushes and drops undelivered events unless dead-lettering is configured
- Service Bus, because Event Grid cannot deliver events to a queue at all and therefore cannot let a consumer pull at its own pace
