- A
roles/storage.objectAdmin with deletion permissions removed via a custom role
Why wrong: The question asks for predefined roles, not custom.
- B
roles/storage.objectViewer
Why wrong: This role is read-only, does not allow creating buckets.
- C
roles/storage.admin
Why wrong: Storage Admin includes deletion permissions for buckets and objects.
- D
roles/storage.objectCreator
This role allows creating objects but not deleting them.
- E
roles/storage.objectAdmin

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. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 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. However, note that objectCreator does not allow bucket creation. Actually, to create buckets, they need roles/storage.admin or roles/storage.legacyBucketWriter. The question states they need to create and manage buckets, which requires bucket-level permissions. Storage admin includes deletion. Perhaps the intended correct answer is roles/storage.admin and then use a deny policy to block deletion. But that's not a predefined role combination. Given the constraints, the best predefined roles are roles/storage.admin (but it allows deletion) and roles/storage.objectViewer. However, deletion is not allowed. Let's reconsider: To create buckets, they need roles/storage.admin (includes deletion) or roles/storage.legacyBucketWriter (but that is legacy). The question might be flawed. Instead, I'll provide a different question.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Why it's wrong here
This role allows deletion of objects, which is not desired.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related PCSE questions on access control and AAA configuration.
