Answer
Use defaultIfEmpty. Frame the concept in practical terms so you can explain it during interview discussion.
Mono's defaultIfEmpty method is used to supply a default value if the Mono completes without emitting any item. This is particularly useful in scenarios where a fallback value is necessary, like returning a default configuration when a lookup fails.
