Answer: Create a new node pool in the same cluster, and migrate the workload to the new pool.
**Correct Option:** B. Create a new node pool in the same cluster, and migrate the workload to the new pool: This is the correct approach because Google Kubernetes Engine (GKE) does not allow changing the machine type of existing nodes directly. The recommended method is to create a new node pool with the desired machine type (n1-standard-4), migrate the workloads to the new pool, and then delete the old node pool. **Incorrect Options:** A. gcloud container clusters update project-1 --machine-type n1-standard-4: Incorrect because the update command does not support changing node pool machine types. C. gcloud container clusters migrate project-1 --machine-type n1-standard-4: Incorrect as there's no migrate command in the gcloud tool for GKE clusters. D. gcloud container clusters resize project-1 --machine-type n1-standard-4: Incorrect because the resize command changes the number of nodes, not their machine type.
