- A
roles/storage.objectAdmin with deletion permissions removed via a custom role
Why wrong: This is a custom role, not a predefined role.
- B
roles/storage.objectViewer [CORRECT]
Why wrong: Correct. roles/storage.objectViewer allows viewing objects, and combined with objectCreator, it enables creating and viewing objects without deletion.
- C
roles/storage.admin
Why wrong: roles/storage.admin includes deletion permissions, which violates the requirement that engineers cannot delete resources.
- D
roles/storage.objectCreator
Correct. roles/storage.objectCreator allows creating objects, and combined with objectViewer, it provides the necessary access without deletion.
- E
roles/storage.objectAdmin
Why wrong: roles/storage.objectAdmin allows deletion of objects, which is not allowed.
PCSE Least privilege Practice Question
This PCSE practice question tests your understanding of configuring access within a cloud solution environment. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. A key principle to apply: least privilege. 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 company is migrating to Google Cloud and wants to implement least privilege access for their engineers. They have the following requirements: 1) Engineers must be able to create and manage Cloud Storage buckets. 2) Engineers must NOT be able to delete any resources. 3) Engineers should not be granted basic roles. Which two predefined roles should they combine to meet these requirements? (Choose two.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"NOT"Why it matters: Negative qualifier — you are looking for the one option that does NOT apply. Most options will be true; only one is false for this scenario.
Clue:
"least"Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.

Correct answer & explanation
roles/storage.objectCreator
The correct combination is roles/storage.objectCreator and roles/storage.objectViewer. This allows engineers to create and view objects in Cloud Storage buckets without the ability to delete resources. Note that these roles do not provide bucket-level management (like creating or deleting buckets); they only manage objects within existing buckets. However, given the constraints requiring no deletion and no basic roles, this pair is the most appropriate predefined roles for least privilege access to object storage.
Key principle: Least privilege

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.

How to think about this question
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.
KKey Concepts to Remember

- Predefined roles
TExam Day Tips
- 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
Least privilege
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
