1. What is Total ordering ? Mid A. a per-message counter the receiver checks to detect gaps or reordering in a stream B. a guarantee that all messages are delivered in one global sequence, which limits scalability across nodes C. a value attached to a message that determines which partition it lands in, keeping related records together and in sequence D. the situation where messages arrive in a different sequence than sent, common when parallel consumers retry independently
2. Which term means: "a guarantee that all messages are delivered in one global sequence, which limits scalability across nodes"? Mid A. Partition key B. Total ordering C. Partition-level ordering D. Out-of-order delivery
3. Which statement is correct? Mid A. Total ordering — a per-message counter the receiver checks to detect gaps or reordering in a stream B. Total ordering — a guarantee that all messages are delivered in one global sequence, which limits scalability across nodes C. Total ordering — a value attached to a message that determines which partition it lands in, keeping related records together and in sequence D. Total ordering — the property that sequence is preserved only among messages routed to the same partition, not across the whole topic
4. What is Partition-level ordering ? Mid A. a value attached to a message that determines which partition it lands in, keeping related records together and in sequence B. the situation where messages arrive in a different sequence than sent, common when parallel consumers retry independently C. a guarantee that all messages are delivered in one global sequence, which limits scalability across nodes D. the property that sequence is preserved only among messages routed to the same partition, not across the whole topic
