How do you configure Event Grid to only deliver events where the event subject starts with '/documents/'?
- A Advanced filter: subject begins with /documents/
- B Subject filter: subjectBeginsWith: '/documents/' (correct answer)
- C Event type filter
- D Topic filter
Shortcut: Event Grid subscription subject filters support subjectBeginsWith and subjectEndsWith for efficient prefix/suffix matching. This is faster than advanced filters for subject-based routing.
