Multiple choiceHardchapter-11-curatedpremiumnetworkingasynchronous-http
Answer and explanation
Correct answer
D. It reduces total latency by waiting for all futures to complete concurrently.
Why
CompletableFuture.allOf allows multiple asynchronous tasks to run in parallel and waits for all of them to complete. This can significantly reduce the total latency compared to sequential execution, as all tasks are performed simultaneously.
