Answer: Create a cluster on Kubernetes Engine and enable autoscaling on Kubernetes Engine.
The correct answer is **C** because enabling autoscaling on Kubernetes Engine allows the cluster to automatically adjust the number of worker nodes based on the workload demands. This feature ensures that you only pay for the resources you need and automatically scales up or down as required. - **Option A** is incorrect because unmanaged instance groups do not support autoscaling. - **Option B** is incorrect because autoscaling should be enabled on the Kubernetes Engine, not the instance group. - **Option D** is incorrect because manually managing Kubernetes on Compute Engine instances does not provide the autoscaling feature offered by Kubernetes Engine.

To set up a Kubernetes Cluster on Google Cloud Platform that supports autoscaling of worker nodes, which action should you take?
A
Configure a Compute Engine instance as a worker and add it to an unmanaged instance group. Add a load balancer to the instance group and rely on the load balancer to create additional Compute Engine instances when needed.
B
Create a cluster on Kubernetes Engine and enable autoscaling on the instance group of the cluster.
C
Create a cluster on Kubernetes Engine and enable autoscaling on Kubernetes Engine.
D
Create Compute Engine instances for the workers and the master and install Kubernetes. Rely on Kubernetes to create additional Compute Engine instances when needed.
