- A
Use a Cloud Functions proxy to authenticate to BigQuery from the notebook.
Why wrong: Unnecessary extra complexity; the notebook can directly authenticate.
- B
Create a service account with BigQuery access and attach it to the notebook instance.
Best practice: use a service account for consistent, granular permissions that are not tied to a specific user.
- C
Log in to the notebook using the user's Google Cloud credentials via oauth2client.
Why wrong: While possible, this relies on the user's personal credentials and may not be suitable for production or sharing.
- D
Grant the Compute Engine default service account BigQuery access.
Why wrong: The default service account may not have the required permissions by default, and it's better to create a dedicated service account.
PDE Preparing and Using Data for Analysis Practice Question
This PDE practice question tests your understanding of preparing and using data for analysis. 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 uses Vertex AI Workbench notebooks for data exploration and model development. They want to ensure that the notebook environment can access BigQuery data using the same permissions as the user's Google Cloud account. What is the recommended setup?
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
Create a service account with BigQuery access and attach it to the notebook instance.
Vertex AI Workbench notebooks can use user-managed notebooks with user credentials. By setting the 'User-managed notebook' type and using the 'Add service account' option, you can grant the notebook instance a service account with appropriate BigQuery permissions. Alternatively, you can use the built-in 'Use the same identity as the user' option which uses the user's credentials via OAuth. However, the recommended approach for production is to use a service account for consistent permissions.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
