Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
DeadLetterMessageAsync()
After receiving a message in PeekLock mode, a worker can settle it by calling CompleteMessageAsync or DeferMessageAsync (or AbandonMessageAsync / DeadLetterMessageAsync). The question asks for settling after successful processing, which is `CompleteMessageAsync()`. Wait, let's look at the settlement options: CompleteMessageAsync and DeadLetterMessageAsync or AbandonMessageAsync. To settle a message (meaning finalize its disposition), methods are `CompleteMessageAsync`, `AbandonMessageAsync`, `DeferMessageAsync`, `DeadLetterMessageAsync`. Specifically for successful processing, it is `CompleteMessageAsync`. Let's select two settlement disposition methods.
