Google ACE Practice Question: Ensuring Successful Operation of a Cloud Solution
This ACE practice question tests your understanding of ensuring successful operation of a cloud solution. 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.
Your BigQuery dataset contains a table with sensitive customer data. You want to allow a data analyst to query the table but prevent them from viewing the data directly. You also need to ensure they cannot export the data. Which TWO IAM roles should you grant the analyst? (Choose two.)
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
✓
roles/bigquery.jobUser
BigQuery Data Viewer allows querying but not viewing table data directly? Actually, BigQuery Data Viewer allows reading table data. However, the scenario is tricky: to prevent viewing data directly, you might need to use authorized views. But among roles, BigQuery Job User allows running jobs (queries) without reading data, and BigQuery Data Viewer allows reading data but not exporting. The combination of Job User and Data Viewer would allow querying and reading data. But the requirement is to prevent viewing data directly, so perhaps they should not have Data Viewer. A better approach is to grant BigQuery Job User and BigQuery Data Viewer? Actually, without Data Viewer, they cannot query tables. So the correct combination is BigQuery Job User (to submit queries) and BigQuery Data Viewer (to read the table). However, Data Viewer allows viewing data. To prevent direct viewing, you could use column-level security or authorized views. But the question asks for IAM roles. The standard answer for allowing querying but not direct access is to grant BigQuery Job User and BigQuery Data Viewer on the dataset. I'll go with that.
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 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.
