- A
Set min-instances to 0 and max-instances to 100
Why wrong: Min-instances=0 means no warm instances; the service scales from zero, causing cold start latency.
- B
Set max-instances to a high value and concurrency to 1
Why wrong: Max-instances limits the total number of instances, but does not keep warm instances. Concurrency=1 limits each instance to one request, which is inefficient for high-throughput.
- C
Set min-instances to 10 and CPU to always-on
Min-instances ensures 10 warm instances are always ready, and CPU always-on reduces latency by keeping CPU allocated even when not serving requests.
- D
Set max-instances to 0 (unlimited) and concurrency to 80
Why wrong: Unlimited max-instances could lead to cost spikes, and concurrency=80 is default. This does not keep warm instances; cold starts may still occur.
Google PCA Practice Question: Managing and Provisioning a Solution Infrastructure
This PCA practice question tests your understanding of managing and provisioning a solution infrastructure. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 company has a Cloud Run service that processes high-throughput requests. They want to reduce latency by keeping a baseline of warm instances always ready to handle traffic. Which Cloud Run configuration parameters should they adjust?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"always"Why it matters: Absolute qualifier. An answer using 'always' is only correct if there are genuinely no exceptions — absolute statements are often wrong in networking.
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 min-instances to 10 and CPU to always-on
Setting min-instances to a value greater than 0 ensures that Cloud Run keeps at least that many instances warm, ready to serve requests without cold start latency. Max-instances sets an upper limit. Concurrency controls how many requests each instance can handle. CPU allocation can be set to always-on to reduce latency, but that is a separate setting.
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.
- ✗
Set min-instances to 0 and max-instances to 100
Why it's wrong here
Min-instances=0 means no warm instances; the service scales from zero, causing cold start latency.
- ✗
Set max-instances to a high value and concurrency to 1
Why it's wrong here
Max-instances limits the total number of instances, but does not keep warm instances. Concurrency=1 limits each instance to one request, which is inefficient for high-throughput.
- ✓
Set min-instances to 10 and CPU to always-on
Why this is correct
Min-instances ensures 10 warm instances are always ready, and CPU always-on reduces latency by keeping CPU allocated even when not serving requests.
Clue confirmation
The clue word "always" in the question point toward this answer.

Why it's wrong here
Unlimited max-instances could lead to cost spikes, and concurrency=80 is default. This does not keep warm instances; cold starts may still occur.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
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.
