Final answer:
In Kinesis Data Firehose, transformation and delivery failures result in records being skipped and discarded.
Step-by-step explanation:
In Kinesis Data Firehose, when a transformation failure occurs, the record is skipped and discarded. This means that the record is not retried indefinitely and will not be delivered to the destination. Similarly, when a delivery failure occurs, the record is also skipped and discarded, without being retried or backed up to an S3 bucket.
