Explanation
B is correct because Apache Flink provides multiple built-in restart strategies to handle task failures automatically. Flink supports strategies such as fixed-delay (retries after a set interval), failure-rate (limits retries within a time window), and no restart (fails immediately without retry) - all configurable via flink-conf.yaml or programmatically.
A is wrong because claiming Flink has no restart strategy ignores the core fault-tolerance feature that makes Flink production-ready. The "no restart" strategy is itself a valid option, meaning the concept of restart strategies definitely exists in Flink.
Memory tip: Think of Flink's restart strategies like a car's engine recovery options - you can choose to retry immediately, retry with a delay, give up after too many failures, or never retry at all. The existence of a "no restart" option proves restart strategies exist as a configurable system.
