PDE Ingesting and Processing the Data Practice Question
A company uses Workflows to orchestrate a series of Google Cloud services for data processing. They need to call an external HTTP API as part of the workflow and handle potential failures with retries. Which Workflows feature should they use?
⚠ Common exam trap
Google Cloud Workflows often tests the distinction between workflow orchestration features (retry, subworkflows, parallel, conditional) and candidates mistakenly choose parallel steps or subworkflows thinking they inherently provide fault tolerance, but only a retry policy directly addresses automatic retries on failure.
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
✓
Retry policy on the step
Workflows provides a built-in retry policy that can be configured on individual steps to automatically retry an HTTP call upon transient failures (e.g., 5xx server errors or network timeouts). This allows the workflow to handle external API failures without custom code, using exponential backoff and a maximum retry count.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Retry policy on the step
Why this is correct
Retry policy allows specifying retry conditions and limits for a step.
- ✗
Subworkflows
Why it's wrong here
Subworkflows are for modularity, not for retry logic.
- ✗
Parallel steps
Why it's wrong here
Parallel steps run steps concurrently, not for retries.
- ✗
Conditional steps
Why it's wrong here
Conditional steps handle branching logic, not retries.
