- A
Use a node pool with a service account that has the required roles
Why wrong: Node-level service accounts are used for nodes, not individual pods; this would give access to all pods on the node, which is not least privilege.
- B
Grant the GSA the IAM role directly on the namespace using RBAC
Why wrong: RBAC is for Kubernetes-level authorization, not Google Cloud IAM; it cannot grant GCP permissions.
- C
Use Workload Identity to bind the KSA to a GSA with the Artifact Registry Writer role
Workload Identity enables keyless authentication by allowing the KSA to impersonate the GSA.
- D
Create a JSON key for the GSA, store it as a Kubernetes secret, and mount it into the pod
Why wrong: This involves managing keys, which is not best practice; workload identity is the recommended approach.
PCSE Practice Question: Configuring Access Within a Cloud Solution Environment
This PCSE practice question tests your understanding of configuring access within a cloud solution environment. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A DevOps engineer needs to allow a CI/CD pipeline running in Google Kubernetes Engine (GKE) to push images to a specific Artifact Registry repository. The pipeline uses a Kubernetes service account. What is the best practice to grant this access without creating a JSON key for a Google service account?
Clue words in this question

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Use Workload Identity to bind the KSA to a GSA with the Artifact Registry Writer role
Workload Identity for GKE allows you to bind a Kubernetes service account (KSA) to a Google service account (GSA). The KSA can then impersonate the GSA when accessing Google Cloud APIs, eliminating the need for service account keys.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
