Answer: Create a cluster with both a Spot VM node pool and a node pool by using standard VMs. Deploy the critical deployments on the node pool by using standard VMs and the fault-tolerant deployments on the Spot VM node pool.
The correct answer is D. Create a cluster with both a Spot VM node pool and a node pool by using standard VMs. Deploy the critical deployments on the node pool by using standard VMs and the fault-tolerant deployments on the Spot VM node pool. Spot VMs are cost-effective but can be preempted at any time, making them suitable for fault-tolerant parts of the application that can afford downtime. Standard VMs, while more expensive, provide consistent availability and are ideal for critical parts of the application that must always be available. By creating a cluster with both types of node pools, you can optimize for cost while ensuring the availability of critical application components.

Your company has developed an application intended to be deployed on Google Kubernetes Engine (GKE). This application comprises multiple components, where some components are non-fault-tolerant and can tolerate downtime, while other components are critical and require constant availability without any downtime. Given these requirements, you need to configure a GKE cluster in a way that ensures high availability for the critical components and minimizes operational costs for the overall deployment. How should you configure the GKE cluster to achieve these goals?
A
Create a cluster with a single node-pool by using standard VMs. Label the fault-tolerant Deployments as spot_true.
B
Create a cluster with a single node-pool by using Spot VMs. Label the critical Deployments as spot_false.
C
Create a cluster with both a Spot VM node pool and a node pool by using standard VMs. Deploy the critical deployments on the Spot VM node pool and the fault-tolerant deployments on the node pool by using standard VMs.
D
Create a cluster with both a Spot VM node pool and a node pool by using standard VMs. Deploy the critical deployments on the node pool by using standard VMs and the fault-tolerant deployments on the Spot VM node pool.
