- A
Manually add a column with a boolean indicating if the timestamp falls on a weekend.
Why wrong: This can be done in preprocessing, but AutoML Tables does not provide a built-in function for it; however, it's a valid technique outside the tool.
- B
Create a new column with the difference between two timestamps.
You can precompute this in the source data and include it as a feature.
- C
Use the 'feature engineering' option to add polynomial features.
AutoML Tables can automatically create cross features and polynomial features.
- D
Apply a SQL UDF in the AutoML Tables training configuration.
Why wrong: AutoML Tables does not support SQL UDFs directly in training.
- E
Extract day of week from timestamp using the AutoML Tables UI.
AutoML Tables can automatically extract timestamp components.
PDE Preparing and Using Data for Analysis Practice Question
This PDE practice question tests your understanding of preparing and using data for analysis. 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.
A company uses AutoML Tables to train a classification model. They want to improve model performance by engineering new features from existing timestamp columns. Which three techniques can they apply within AutoML Tables? (Choose 3)
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 new column with the difference between two timestamps.
AutoML Tables automatically extracts features from timestamp columns, such as day of week, month, hour, etc. Users can also manually create new columns via the UI or by preprocessing data before import. However, manual SQL functions cannot be used directly within AutoML Tables.
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.

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.
