Answer-first summary for fast verification
Answer: 1. Create a new Node Pool with the n2-highmem-16 machine type. 2. Deploy the new pods.
Option A is incorrect because upgrading the existing nodes does not meet the requirement for deploying new pods on n2-highmem-16 machine type nodes. Option B is correct as adding a new node pool allows for the deployment of new pods on the same cluster without downtime. Options C and D are incorrect because creating a new cluster and deleting the old one would result in downtime, which is not acceptable for a live production app. [Learn more about node pools](https://cloud.google.com/kubernetes-engine/docs/concepts/node-pools).
