- A
Create a clustered table on the user ID column.
Why wrong: Clustering helps but requires table redesign; the stem says not to change the underlying table.
- B
Apply a filter to limit data to the last month only.
Why wrong: Filtering reduces data but changes the user experience; not a performance optimization for all cases.
- C
Enable BigQuery BI Engine on the project.
BI Engine accelerates queries by caching data in memory, improving Looker Studio dashboard performance.
- D
Use Looker Studio's extract data functionality.
Why wrong: Extracts create a static snapshot, which may not be suitable for real-time data and adds maintenance.

PDE Preparing and Using Data for Analysis Practice Question
This PDE practice question tests your understanding of preparing and using data for analysis. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 team uses Looker Studio to build dashboards on top of BigQuery. The dashboards are slow when filtering on a high-cardinality dimension (e.g., user ID). You want to improve performance without changing the underlying BigQuery table design. Which action should you take?
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
✓
Enable BigQuery BI Engine on the project.
BI Engine automatically caches the BigQuery tables in memory for Looker Studio, accelerating queries on any dimension. Enabling BI Engine on the project will improve dashboard performance.
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.
- ✗
Create a clustered table on the user ID column.
Why it's wrong here
Clustering helps but requires table redesign; the stem says not to change the underlying table.
- ✗
Apply a filter to limit data to the last month only.
Why it's wrong here
Filtering reduces data but changes the user experience; not a performance optimization for all cases.
- ✓
Enable BigQuery BI Engine on the project.
Why this is correct
BI Engine accelerates queries by caching data in memory, improving Looker Studio dashboard performance.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Use Looker Studio's extract data functionality.
Why it's wrong here
Extracts create a static snapshot, which may not be suitable for real-time data and adds maintenance.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
