Correct answer & explanation
✓
300 seconds
The Kinesis Data Firehose delivery stream is configured with a buffer interval of 300 seconds (5 minutes) and a buffer size of 5 MB. During a burst of 10 MB every 2 minutes, the buffer will fill to 5 MB in 1 minute, so the buffer will be flushed every minute due to reaching the size threshold. However, the question asks for the maximum time it will take for data to be delivered to S3 during a burst. The maximum time is determined by the buffer interval, which is 300 seconds. Even though the size trigger may cause earlier flushes, the maximum possible time before delivery is the interval setting of 300 seconds. Therefore, the correct answer is 300 seconds (option A).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
300 seconds
Why this is correct
The buffer interval is 300 seconds; even with bursts, the maximum time is the interval.
- ✗
60 seconds
Why it's wrong here
60 seconds is not the maximum; the interval is 300 seconds.
- ✗
1 second
Why it's wrong here
1 second is not realistic.
- ✗
600 seconds
Why it's wrong here
600 seconds is not configured.
