How should you prepare to handle the predicted growth?

You are performing a semiannual capacity planning exercise for your flagship service. You expect a service user growth rate of 10% month-over-month over the next six months. Your service is fully containerized and runs on Google Cloud Platform (GCP). using a Google Kubernetes Engine (GKE) Standard regional cluster on three zones with cluster autoscaler enabled. You currently consume about 30% of your total deployed CPU capacity, and you require resilience against the failure of a zone. You want to ensure that your users experience minimal negative impact as a result of this growth or as a result of zone failure, while avoiding unnecessary costs.

How should you prepare to handle the predicted growth?
A . Verity the maximum node pool size, enable a horizontal pod autoscaler, and then perform a load test to verity your expected resource needs.
B . Because you are deployed on GKE and are using a cluster autoscaler. your GKE cluster
will scale automatically, regardless of growth rate.

C . Because you are at only 30% utilization, you have significant headroom and you won’t need to add any additional capacity for this rate of growth.
D . Proactively add 60% more node capacity to account for six months of 10% growth rate, and then perform a load test to make sure you have enough capacity.
