Practice Test 1 | Google Cloud Certified Associate Cloud Engineer | Dumps | Mock Test
You have created a Kubernetes engine cluster named ‘mycluster’. You’ve realized that you need to change the machine type for the cluster from n1-standard-1 to n1-standard-4. What is the command to make this change?
A. You must create a new node pool in the same cluster and migrate the workload to the new pool.
B. gcloud container clusters update mycluster –machine-type n1-standard-4
C. This action is not possible.
D. gcloud container clusters resize mycluster –machine-type n1-standard-4
Explanation:
Correct answer A
Feedback
A (Correct answer) – You must create a new node pool in the same cluster and migrate the workload to the new pool. You cannot change the machine type for an individual node pool after creation. You need to create a new pool and migrate your workload over.
Here are the steps for “Migrating workloads to different machine types”
https://cloud.google.com/kubernetes-engine/docs/tutorials/migrating-node-pool
B – gcloud container clusters update mycluster –machine-type n1-standard-4 updates cluster settings for an existing container cluster. You can use this command to specify –max-nodes –min-nodes for autoscaling purpose not for changing machines type https://cloud.google.com/sdk/gcloud/reference/container/clusters/update
C – This action is not possible. It’s possible to migrate workloads running on a Kubernetes Engine cluster to a new set of nodes without incurring downtime for your application. See “Migrate the workloads”
D – gcloud container clusters resize mycluster –machine-type n1-standard-4. Resizes an existing cluster for running containers not for changing machine type https://cloud.google.com/sdk/gcloud/reference/container/clusters/resize
