1.
What is the main topic of Mia and Robert’s conversation?
Why system overload happens during peak business hours
Ways to handle errors and retries in asynchronous message processing
How to manually review customer messages for mistakes
How to write clearer error logs in a database
Explanation:
Mia explains error handling, logging, retries with exponential backoff, and using a dead-letter queue, so the conversation is about handling errors and retries in asynchronous message processing.
2.
What does Mia say should be done first when an error occurs?
Delete the message immediately
Wait longer after each retry
Log every error for future analysis
Send the message to a dead-letter queue
Explanation:
Mia explicitly says, “First, log every error for future analysis.”
3.
According to Mia, what does an exponential backoff strategy mean?
Waiting longer after each retry
Stopping all retries after the first failure
Reviewing the message manually before retrying
Retrying the message more often over time
Explanation:
Mia explains that exponential backoff means “waiting longer after each retry.”
4.
Why does Mia say exponential backoff helps with system overload?
Because it guarantees every retry will succeed
Because it removes the need to log errors
Because it reduces repeated failures quickly
Because it sends every failed message to review immediately
Explanation:
Mia says the strategy helps because “it reduces repeated failures quickly,” which supports the idea that it can lessen the strain caused by repeated retry attempts.
5.
What should happen if a message still fails after retries?
It should be retried forever
It should be deleted without review
It should be sent to a dead-letter queue for manual review
It should be logged and then ignored
Explanation:
Mia says that if the message still fails after retries, it should be moved to a dead-letter queue for manual review.
