Exam Associate Cloud Engineer topic 1 question 145 discussion

B is correct answer, read below form google docs; This tutorial demonstrates how to migrate workloads running on a Google Kubernetes Engine (GKE) cluster to a new set of nodes within the same cluster without incurring downtime for your application. Such a migration can be useful if you want to migrate your workloads to nodes with a different machine type. Background A node pool is a subset of machines that all have the same configuration, including machine type (CPU and memory) authorization scopes. Node pools represent a subset of nodes within a cluster; a container cluster can contain one or more node pools. When you need to change the machine profile of your Compute Engine cluster, you can create a new node pool and then migrate your workloads over to the new node pool. To migrate your workloads without incurring downtime, you need to: Mark the existing node pool as unschedulable. Drain the workloads running on the existing node pool. Delete the existing node pool. https://cloud.google.com/kubernetes-engine/docs/tutorials/migrating-node-pool#creating_a_node_pool_with_large_machine_type

B is the right answer , if you need the new, and if you want to old one also then its D

B is correct, creating another cluster just doesnt make any sense, node pools are intended for this situations

Answer is obviously B (read @GCP_Student1 and @Bobbybash replies)

B. Create a new Node Pool and specify machine type n2"highmem"16. Deploy the new pods. Creating a new Node Pool with the required machine type is the correct approach to deploy additional pods without any downtime. This approach allows you to scale the cluster horizontally by adding more nodes to the existing cluster. By creating a new Node Pool, you can add n2"highmem"16 nodes to the existing cluster, and deploy new pods on these nodes without affecting the existing services running on the n1"standard"2 nodes. This way, you can ensure high availability and zero downtime during the deployment. Option A (gcloud container clusters upgrade) upgrades the entire cluster, and Option C and D (creating a new cluster) involve deleting the existing cluster, which may cause downtime.

The keyword is "additional". Answer B is good if you want to replace with the new VMs. In this case you want the existing ones as well as the new ones. Therefore D.

B makes perfect sense.

B is correct

B is correct

ANS : B 1. The title did not say to delete four GKE n1.

B,You need to create new node pool for cluster

I guess it's B. I couldn't find resize parameter under cluster upgrade. C and D are incorrect because it's no need to create new cluster.

A. Use gcloud container clusters upgrade. Deploy the new services.

Answer is B - When you need to change the machine profile of your Compute Engine cluster, you can create a new node pool and then migrate your workloads over to the new node pool.
