Which action enables automatic scaling in the cloud management tool?

• A. Add additional CPUs and RAM to the host
• B. Adjust the cloud workload by migrating resource-intensive applications to different hosts
• C. Add additional hosts to the environment using the cloud management tool
• D. Enable automatic scaling in the cloud management tool

Answer: (D)

Automatic scaling is about the system adjusting resources on its own in response to changing demand. Enabling auto-scaling in the cloud management tool turns on this behavior, allowing the platform to monitor metrics (like CPU or memory usage) and automatically add or remove resources as needed. Without turning on auto-scaling, the tool won’t make those dynamic adjustments. The other actions are manual or static changes: adding CPUs and RAM to a single host is vertical scaling and requires you to decide when to do it; migrating workloads to different hosts is manual load balancing rather than automatic scaling; simply adding more hosts expands capacity but does not establish the rules for automatic adjustments. Enabling automatic scaling sets up those rules and lets the system handle scaling automatically.
