The answer is that Alice has only the objectViewer role, which does not include delete permissions. In Google Cloud Storage, the roles/storage.objectViewer role grants read-only access to objects, specifically the storage.objects.get and storage.objects.list permissions, but it explicitly lacks storage.objects.delete. Bob, despite appearing in the same IAM policy binding, likely inherits a role with delete permissions from a higher-level resource, such as the project, where a role like roles/storage.objectAdmin or roles/storage.legacyObjectOwner is applied. On the Google Professional Cloud Security Engineer exam, this scenario tests your understanding of IAM role inheritance and the principle of least privilege—a common trap is assuming all principals in a single binding share the same effective permissions. Remember: viewer can see, but only owner or admin can delete; if Bob can delete, check the project-level bindings, not just the bucket policy.
PCSE Practice Question: Managing operations in a cloud solution environment
This PCSE practice question tests your understanding of managing operations in a cloud solution environment. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Refer to the exhibit. This IAM policy is applied to a Google Cloud Storage bucket. Alice reports she cannot delete objects in the bucket. Bob can delete objects. What is the most likely reason?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Alice has only objectViewer role, which does not allow deletion.
Option A is correct. The policy shows Alice has only the roles/storage.objectViewer role, which does not include delete permissions. Bob, although listed in the same binding, must have additional permissions from another policy (e.g., at the project level) that allow him to delete objects. Option B is incorrect because Bob's ability is likely due to inherited permissions, but the exhibit only shows this policy. Option C is irrelevant because the service account does not affect Bob's permissions. Option D is incorrect; etag is used for concurrent modification prevention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The service account has objectAdmin role, but Bob is not a member.
Why it's wrong here
The service account's role does not affect Bob's permissions.
✗
The etag mismatch causes a conflict.
Why it's wrong here
The etag is used for optimistic concurrency control, not for permission issues.
✗
Bob has a higher role inherited from the project level.
Why it's wrong here
This could be true but is not evident from the exhibit; the question asks for the most likely reason based on the exhibit.
✓
Alice has only objectViewer role, which does not allow deletion.
Why this is correct
The objectViewer role only allows read access to objects, not deletion.

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
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.

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 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.
