- A
Cloud Storage: Storing unstructured data like images, videos, and documents
Cloud Storage is a scalable object store for unstructured data.
- B
Cloud Storage: Storing structured transactional data with strong consistency
Why wrong: Incorrect — this describes Cloud Spanner or Firestore, not Cloud Storage.
- C
Bigtable: Low-latency, high-throughput analytical workloads on structured data
Bigtable is a NoSQL database optimized for large-scale analytical and operational workloads.
- D
Bigtable: Storing relational data with complex joins and transactions
Why wrong: Incorrect — Bigtable does not support SQL joins or complex transactions; this describes Cloud SQL or Spanner.
- E
BigQuery: Serverless data warehouse for running fast SQL queries on petabyte-scale data
BigQuery is a fully managed, serverless data warehouse for analytics.
- F
BigQuery: Real-time transaction processing for small, frequently updated datasets
Why wrong: Incorrect — BigQuery is designed for analytics, not OLTP; this describes Cloud SQL or Firestore.
Matching Google Cloud Storage Options to ML Use Cases
This PMLE practice question tests your understanding of cloud storage. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: cloud Storage. 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.
Match each Google Cloud storage option to its best use case.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Trap: You might think Bigtable can handle relational data because it supports structured data, but it lacks joins and transactions. Similarly, BigQuery is often mistaken for an OLTP database, but it's designed for analytics on large datasets.

TExam Day Tips
- 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
Cloud Storage
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
