Question 5/53
A bank uses a Kafka cluster for credit card payments. What should be the value of the property unclean.leader.election.enable?
Correct Answer: A
Setting unclean.leader.election.enable to true means we allow out-of-sync replicas to become leaders, we will lose messages when this occurs, effectively losing credit card payments and making our customers very angry.
