There are three Kubernetes worker nodes, each with 8 CPU cores available. Workloads: - API: 2 replicas, each requesting 6 CPU - Database: 2 replicas, each requesting 4 CPU - Worker: 2 replicas, each requesting 2 CPU Replicas of the same workload must run on different nodes. Ignore system overhead and memory. Can all six Pods be scheduled? Show the placement.
