Cloud Digital Leader Fundamental Cloud Concepts Practice Question
A DevOps engineer notices that a Cloud Function is timing out after 9 minutes. The function performs a long-running data transformation. They need to increase the timeout. What is the maximum timeout they can set for a Cloud Function (1st gen)?
⚠ Common exam trap
GCDL often tests the exact numeric limits of Cloud Functions 1st gen vs 2nd gen, and candidates who remember '60 minutes' from Cloud Run or 2nd gen incorrectly pick it for a 1st gen question.

Correct answer & explanation
✓
9 minutes
For Google Cloud Functions (1st gen), the maximum configurable timeout is 9 minutes (540 seconds). The question states the function is already timing out at 9 minutes, which is the ceiling — the engineer cannot increase it further in 1st gen. To exceed 9 minutes, they must migrate to Cloud Functions 2nd gen (which supports up to 60 minutes) or use Cloud Run.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
15 minutes
Why it's wrong here
15 minutes exceeds the maximum timeout allowed for 1st gen Cloud Functions, which is hard-capped at 540 seconds (9 minutes). The deployment will be rejected if you try to set a value above this limit, so this option is not valid for a 1st gen function.
- ✓
9 minutes
Why this is correct
9 minutes (540 seconds) is the correct maximum timeout for 1st gen Cloud Functions. This is a platform-enforced hard limit; you can configure the timeout field to any value between 1 and 540 seconds, but values above that are not accepted.
- ✗
30 minutes
Why it's wrong here
30 minutes is not a supported timeout for 1st gen Cloud Functions, whose ceiling is 9 minutes. Even though 2nd gen functions and Cloud Run support timeouts up to 60 minutes, 30 minutes is not an available option for this generation and would fail configuration validation.
- ✗
60 minutes
Why it's wrong here
60 minutes is a valid timeout for 2nd gen Cloud Functions and Cloud Run, but it is far above the 9-minute maximum for 1st gen functions. The 1st gen service is restricted to 540 seconds per invocation, so this value cannot be used. This limitation is a common reason to migrate long-running workloads to 2nd gen.
