PCDE Practice Question: Building and Implementing CI/CD Pipelines for a Service
This PCDE practice question tests your understanding of building and implementing ci/cd pipelines for a service. 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 developer wants to deploy a containerized application to Cloud Run using the command line. They need to set the maximum number of concurrent requests per container instance to 80. Which flag should they use with 'gcloud run deploy'?
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
✓
--concurrency
Option D is correct because the `--concurrency` flag in `gcloud run deploy` directly sets the maximum number of simultaneous requests that a single container instance can handle. By specifying `--concurrency=80`, the developer limits each instance to processing up to 80 concurrent requests, which helps control resource usage and scaling behavior in Cloud Run.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between instance-level limits (`--max-instances`) and per-instance request limits (`--concurrency`), leading candidates to confuse scaling limits with concurrency settings.
Detailed technical explanation
How to think about this question
Under the hood, Cloud Run uses the `container-concurrency` setting to control how many requests are routed to a single instance via the Knative serving layer. When concurrency is set to 80, the Cloud Run HTTP proxy will queue up to 80 requests per instance before scaling out, which is critical for optimizing cost and latency in high-throughput applications. A real-world scenario is a REST API that handles many small, fast requests; setting concurrency too high can cause resource contention, while too low can increase cold starts and costs.
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.
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.
