PMLE Practice Question: A marketing team wants to analyze customer…
A marketing team wants to analyze customer reviews for sentiment without writing code. Which Google Cloud service should they use?
⚠ Common exam trap
Google Cloud often tests the distinction between services that require coding (like Dataflow or Workbench) versus those that offer pre-built, no-code APIs (like Cloud Natural Language API), leading candidates to mistakenly choose BigQuery ML because it uses SQL, which they perceive as 'low-code' but still requires explicit query writing and model management.
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
✓
Cloud Natural Language API
The Cloud Natural Language API (option D) is the correct choice because it provides pre-trained models for sentiment analysis, entity recognition, and syntax analysis via a simple REST API, requiring no code beyond sending HTTP requests. This aligns perfectly with the requirement to analyze customer reviews for sentiment without writing code, as the API abstracts all ML complexity.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Cloud Dataflow
Why it's wrong here
Dataflow is a code-based Apache Beam pipeline service, so the team would still write pipeline code, failing the no-code requirement. It is the right choice when building custom, programmatic streaming or batch transformation pipelines with bespoke logic.
- ✗
Vertex AI Workbench
Why it's wrong here
Vertex AI Workbench provides managed Jupyter notebooks, which require Python coding, so it fails the no-code requirement. It is the right choice when data scientists need an interactive notebook environment to develop and train custom machine learning models.
- ✗
BigQuery ML
Why it's wrong here
BigQuery ML trains and predicts models using SQL against BigQuery data, so it still requires writing SQL statements, not a no-code interface. It is correct when analysts want to build and evaluate models directly in BigQuery with SQL.
- ✓
Cloud Natural Language API
Why this is correct
Cloud Natural Language API provides pre-trained sentiment analysis via REST calls, returning sentiment scores and magnitudes without model training or code. This satisfies the no-code requirement, unlike Vertex AI, which demands custom model development and programming effort.
