You are managing a Kubernetes cluster, and you need to deploy an application that requires consistent resource usage. The application should have a minimum of 1 CPU and 1 GiB of memory to run correctly, but you also want to set limits to ensure it does not exceed 2 CPUs and 2 GiB of memory to avoid resource contention with other applications. You create a pod specification with resource requests and limits, but when you deploy the pod, it stays in a "Pending" state longer than expected. Which of the following is the most likely reason the pod is stuck in a "Pending" state, and what can you do to resolve the issue?
