Question 7

A company has applied a deny organization policy at the folder level that prevents the use of certain machine series. An IAM policy at the project level grants a user the role of compute.instanceAdmin. The user attempts to create a VM using a denied machine series. What will happen?

Accepted Answer

The VM creation is blocked by the deny policy at the folder level.. Deny policies within organization policies override allow policies, including IAM roles. The deny at the folder level will block the VM creation even if the user has the necessary IAM permissions.

Answer

The user is prompted to request a quota increase.

Answer

The VM is created successfully because the IAM policy allows it.

Answer

The deny policy is overridden by the project-level IAM policy.

Question 10

A company runs a microservices application on Google Kubernetes Engine (GKE) and wants to reduce costs by using preemptible nodes for stateless workloads. However, they need to ensure that critical stateful workloads are not disrupted. Which two actions should they take?

Accepted Answer

Taint the regular node pool and use tolerations for stateful pods. To protect stateful workloads, use node pools with regular VMs and taint them to prevent preemptible pods from scheduling. For stateless workloads, use a separate node pool with preemptible VMs and add tolerations to the pods. Affinity rules or priority classes can also help but are not the primary method.

Answer

Use a single node pool with a mix of regular and preemptible VMs

Answer

Set pod priority class to 'high' for stateful workloads

Answer

Use node affinity rules to schedule stateful pods on regular nodes
