The answer is to containerize the processing logic and trigger it via Cloud Tasks. This is the correct solution because Cloud Run enforces a hard 60-minute request timeout, making synchronous processing of large file uploads unreliable; by offloading the work to Cloud Tasks, the HTTP request returns immediately while the heavy processing runs asynchronously with automatic retries and no timeout limit. On the Google Professional Data Engineer exam, this scenario tests your understanding of Cloud Run’s architectural constraints and your ability to decouple request handling from long-running workloads—a common trap is choosing Cloud Functions or Pub/Sub alone, which lack the built-in retry and queue management that Cloud Tasks provides for reliable task execution. Remember the memory tip: “Cloud Run clocks out at 60, so hand the heavy lifting to Tasks.”
PDE Ensuring solution quality Practice Question
This PDE practice question tests your understanding of ensuring solution quality. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 team deploys a Cloud Run service that processes user-uploaded files. Some requests time out after 60 minutes. They need to handle large files reliably without losing tasks. What is the best solution?
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.
Containerize the processing logic and trigger it via Cloud Tasks.
Cloud Tasks decouples the request, provides retry, and can handle long-running operations without timeout limits.
B
Increase the request timeout to 3600 seconds.
Why wrong: Cloud Run max timeout is 3600s (60 min); the issue is that large files may exceed even that, and synchronous processing ties up the request.
C
Use Cloud Functions instead of Cloud Run.
Why wrong: Cloud Functions also have a 60-minute timeout (HTTP functions) and similar synchronous limitations.
D
Split the file into chunks and process them concurrently.
Why wrong: Chunking adds complexity and still requires a synchronous response within the timeout.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Containerize the processing logic and trigger it via Cloud Tasks.
Cloud Run has a maximum request timeout of 60 minutes. Offloading processing to a Cloud Task decouples the request from the processing, allowing async handling with retries.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

TExam Day Tips
→Underline the problem statement mentally.
→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.
