A cloud operations team receives an alert that a production Kubernetes cluster's node pool has reached 95% memory utilization. New pods are failing to schedule with 'Insufficient memory' errors. What is the most appropriate immediate action?

Question

Accepted Answer

A. Add additional nodes to the node pool (scale out) to provide additional memory capacity for pod scheduling. When a Kubernetes node pool is at capacity and pods cannot be scheduled due to insufficient resources, the correct action is to scale out by adding nodes, which provides additional schedulable capacity immediately. This is a lifecycle management and scaling operation under the CompTIA Cloud+ V4 Operations domain.
