Objective 2.2
CDLDetermine which Google Cloud data management products are applicable to different business use cases.
Objective 2.2 sits in Exploring Data Transformation with Google Cloud, which carries 18% of the Cloud Digital Leader exam. The questions below are original, written from the official objective title above, and each explanation cites the Google Cloud page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A data team asks why a long query and a heavy load job do not slow each other down in BigQuery. What does its architecture do?
Correct.
Concept
Contention comes from sharing one resource pool between jobs of different shapes. Splitting the pool along that seam lets each side scale on its own.
Why B
The architecture is a storage layer and a compute layer that operate independently over a petabit-scale network, so each allocates resources without affecting the other.
Source
Google Cloud: BigQuery overview, checked August 2026BigQuery's architecture consists of two parts: a storage layer that ingests, stores, and optimizes data and a compute layer that provides analytics capabilities. These compute and storage layers efficiently operate independently of each other thanks to Google's petabit-scale network that enables the necessary communication between them. Legacy databases usually have to share resources between read and write operations and analytical operations. This can result in resource conflicts and can slow queries while data is written to or read from storage. Shared resource pools can become further…
Now you: objective 2.2 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
An analyst asks how BigQuery lays out table data on disk and what that layout is tuned for. Which describes it?
Sample question 2 of 3
A company holds data in Cloud Storage and Bigtable and does not want to copy it into the warehouse. What lets BigQuery query it in place?
Sample question 3 of 3
A finance team wants predictable BigQuery compute spend rather than paying per query run. Which feature makes that switch?
