Google PCA Practice Question: Managing and Provisioning a Solution Infrastructure
An organization runs a Cloud Run service that processes incoming HTTP requests. Under heavy load, some requests timeout. The team wants to reduce cold starts and ensure consistent performance. They set min instances to 1, but the issue persists. Which additional configuration should they change?
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
✓
Set CPU always allocated to true
Increasing CPU allocation ensures that even idle instances have CPU, reducing latency for incoming requests.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reduce concurrency
Why it's wrong here
Reducing concurrency limits requests per instance but does not address cold starts or timeout issues.
- ✓
Set CPU always allocated to true
Why this is correct
This ensures the instance always has CPU, reducing latency for requests that hit an idle instance.
- ✗
Increase max instances
Why it's wrong here
Increasing max instances allows more concurrency but does not directly reduce cold start latency.
- ✗
Increase request timeout
Why it's wrong here
Increasing timeout only allows longer requests; it does not solve the root cause of slow startup.

Latency is the time delay between a request being sent over a network and the response being received, often measured in milliseconds.
Key term
Cloud Run
Cloud Run is a fully managed compute platform from Google Cloud that lets you run containerized applications in a serverless environment, automatically scaling from zero to thousands of requests.
