A message-queue-based microservices workload automatically scales compute workers whenever signals appear in the queue instead of relying on a cron schedule or manual intervention. Which statement best explains how this event-driven design improves resource allocation?
It waits until all services are restarted and then applies dynamic resource changes.
It reconfigures infrastructure when a system administrator triggers a rebuild of the environment.
It modifies usage at certain intervals, preventing frequent evaluations.
It adjusts resources using signals from the queue instead of repeated checks or human action.
The design that triggers tasks upon receiving signals from the queue reduces overhead by adjusting resources as soon as new activity occurs. Scheduling at fixed intervals or relying on manual commands delays response and uses unnecessary processing. Using these signals helps the system respond when needed, rather than waiting or requiring user intervention.
