Google PCA Manage and provision cloud infrastructure Practice Question
This PCA practice question tests your understanding of manage and provision cloud infrastructure. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Alice and all users from example.com can view objects.
The IAM policy grants the `storage.objectViewer` role to both the user `alice@example.com` and the domain `example.com`. This means Alice and all authenticated users from the example.com domain (i.e., any Google account ending in @example.com) can view objects in the bucket. The correct answer is C because the policy explicitly includes both principals.
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.
✗
All users from example.com can view objects.
Why it's wrong here
The policy also includes Alice specifically.
✗
Only Alice can view objects.
Why it's wrong here
The domain binding is also present.
✓
Alice and all users from example.com can view objects.
Why this is correct
The bindings include both Alice and the entire domain.

✗
Alice can view objects but not list buckets.
Why it's wrong here
The policy grants objectViewer, which does not include listing buckets, but it also includes the domain.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the additive nature of IAM policies — candidates mistakenly think a more specific user binding overrides a broader domain binding, but in reality, all granted permissions are combined, not mutually exclusive.
Detailed technical explanation
How to think about this question
The `storage.objectViewer` role includes permissions like `storage.objects.get` and `storage.objects.list`, which allow viewing and listing objects within a bucket, but not listing all buckets in a project. The domain scope (`example.com`) uses Google Workspace or Cloud Identity to match any authenticated user with an email in that domain. Under the hood, IAM evaluates all bindings additively, so both the user and domain grants are combined, giving Alice and all example.com users the same object-viewing permissions.
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.
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
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.
