PMLE Collaborating to manage data and models Practice Question
Which TWO of the following are best practices for managing data in a collaborative machine learning environment on Google Cloud?
⚠ Common exam trap
Google Cloud often tests the misconception that 'replication equals performance' or that 'single bucket simplicity is best,' when in reality collaborative ML requires discoverability (Data Catalog) and reproducibility (versioning) over raw storage or access control alone.
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
✓
Use Cloud Data Catalog to discover and annotate datasets.
Cloud Data Catalog provides a managed metadata management service that allows teams to discover, annotate, and manage datasets across Google Cloud. It enables data scientists to search for datasets by tags, descriptions, and schema, which is essential for collaboration and data governance in a multi-user ML environment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Always replicate data across multiple regions to ensure low latency.
Why it's wrong here
Replication is not always needed and increases cost.
- ✗
Implement fine-grained access control using IAM conditions.
Why it's wrong here
While important for security, this is not specifically a data management practice.
- ✓
Use Cloud Data Catalog to discover and annotate datasets.
Why this is correct
Data Catalog aids in data governance and collaboration.
- ✗
Store all raw data in a single Cloud Storage bucket for easy access.
Why it's wrong here
A single bucket may cause permission and organizational challenges.
- ✓
Use data versioning with tools like DVC or Dataflow to track changes.
Why this is correct
Versioning enables reproducibility and rollback.
