B.Peek Lock followed by Complete after success
C.Receive and Delete before processing
D.Receive and Delete followed by an assumed broker rollback of SQL

Show the answer and explanation

✓ Correct answer

Peek Lock followed by Complete after success

Peek Lock preserves recoverability until the receiver completes the message. Receive and Delete removes at receipt, completing early can lose work on a later failure, and broker reception does not provide automatic rollback of external SQL writes. Source guide: PDF page(s) 50.
