B) Use a Google service account to run the Pod with Workload Identity. This is the way to go, unless you want to accidentally grant your entire cluster access to your Google Cloud resources.

Hmm, I wonder if the exam will also ask about the best way to store my Google service account password - maybe in a Post-it note on my monitor?

A) Assign a Google service account to the GKE nodes. This is a valid approach, but Workload Identity is the recommended way to access Google Cloud services.

Using RBAC with a service account sounds familiar, but I’m not clear on how it integrates with GKE for accessing other services.

I feel like storing the service account credentials as a Kubernetes Secret could lead to security issues, but I can't recall the specifics.

I remember practicing a similar question, and I think assigning a service account to the GKE nodes might not be the most secure choice.

Option B is definitely the way to go here. Workload Identity is the recommended approach for accessing Google Cloud services from GKE. It's more secure than storing credentials as a Kubernetes Secret.

Hmm, I'm a bit unsure about this one. I'll need to double-check the documentation to make sure I understand the differences between the options. Assigning a service account to the nodes or using RBAC could also work, but Workload Identity sounds like the best approach.
