PCD Managing application performance monitoring Practice Question
This PCD practice question tests your understanding of managing application performance monitoring. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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.
A developer notices that a Cloud Function is timing out after 60 seconds. The function makes an external API call that occasionally takes longer than the timeout. What is the best practice to handle this?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the timeout for the specific Cloud Function to a higher value
Option C is correct because Cloud Functions have a configurable timeout per function (up to 540 seconds for HTTP functions). Increasing the timeout for the specific function that makes the slow external API call directly addresses the timeout issue without affecting other functions or introducing unnecessary retry overhead. This is the most targeted and efficient solution.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Implement retry logic without changing the timeout
Why it's wrong here
Retries without a longer timeout will still fail.
✗
Increase the timeout for all Cloud Functions in the project
Why it's wrong here
Increasing all timeouts is not a best practice and may hide issues.
✓
Increase the timeout for the specific Cloud Function to a higher value
Why this is correct
Adjusting the timeout for the specific function allows the external call to complete.
Clue confirmation
The clue word "best" in the question point toward this answer.

✗
Decrease the timeout to fail fast and implement retry logic
Why it's wrong here
Decreasing timeout would cause more failures.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that retry logic alone can solve timeout issues, but the trap here is that retries do not extend the execution window—the function must complete within the configured timeout for any single invocation to succeed.
Detailed technical explanation
How to think about this question
Cloud Functions timeout is set via the `--timeout` flag during deployment or in the `gcloud functions deploy` command, with a default of 60 seconds and a maximum of 540 seconds for HTTP functions (9 minutes) and 540 seconds for background functions (though background functions have a 10-minute maximum in some regions). The timeout is enforced by the Cloud Functions infrastructure, which terminates the function instance if execution exceeds the configured limit. In a real-world scenario, if the external API call occasionally spikes to 90 seconds, setting the timeout to 120 seconds provides a buffer while still allowing the function to fail fast for truly hung requests.

Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
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
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
