- A
Configure the application to emit metrics to a StatsD daemon and configure Cloud Monitoring to scrape it
Why wrong: Cloud Monitoring does not natively scrape StatsD; you would need a sidecar or custom exporter.
- B
Use the Google.Cloud.Monitoring.V3 client library to call the metric API directly
Correct. The client library allows programmatic creation and writing of custom metrics.
- C
Install the Stackdriver Monitoring agent and enable custom metrics
Why wrong: Stackdriver agent is deprecated in favor of Ops Agent. Even then, it collects system metrics, not custom application metrics.
- D
Use gcloud beta monitoring metrics create to define and write metrics from the application
Why wrong: gcloud commands are CLI tools for administration, not for in-application metric writing.
- E
Instrument the application with OpenTelemetry .NET SDK and configure the Google Cloud exporter
Correct. OpenTelemetry is a vendor-neutral instrumentation that can export to Cloud Monitoring.
PCDE Implementing Service Monitoring Strategies Practice Question
This PCDE practice question tests your understanding of implementing service monitoring strategies. 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.
Your team wants to collect custom metrics from a .NET application running on Compute Engine and send them to Cloud Monitoring. Which TWO approaches are valid?
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
Use the Google.Cloud.Monitoring.V3 client library to call the metric API directly
Valid approaches: (1) Use the OpenTelemetry .NET SDK to instrument the application and export metrics to Cloud Monitoring via the Google Cloud exporter. (2) Use the Google.Cloud.Monitoring.V3 client library to write custom metrics directly via the Monitoring API. The other options are invalid: Stackdriver client is deprecated, StatsD is not directly supported by Cloud Monitoring, and gcloud commands are for administration, not application-level metric writing.
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
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.
Trap categories for this question
Command / output trap
gcloud commands are CLI tools for administration, not for in-application metric writing.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
