Practice Test 3 | Google Cloud Certified Professional Cloud Architect | Dumps | Mock Test
You need to create a new Kubernetes Cluster on Google Cloud Platform that can autoscale the number of worker nodes. What should you do?
A. Create a cluster on Kubernetes Engine and enable autoscaling during cluster creation.
B. Create a cluster on Kubernetes Engine and enable autoscaling on the instance group of the cluster.
C. 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.
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.
Correct answer: A
Option A is correct because this is the way to set up an autoscaling Kubernetes cluster.
Option B is incorrect because you should not manage the scaling of Kubernetes through the MIG.
Option C is incorrect because a UMIG cannot scale based on a load balancer and this is not the correct way to set up Kubernetes.
Option D is incorrect because Kubernetes will not create additional instances when deployed on Compute Engine.
