PCD Managing application performance monitoring Practice Question
This PCD practice question tests your understanding of managing application performance monitoring. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
You are configuring a Cloud Monitoring alerting policy for a Cloud Run service. The service has a maximum of 10 concurrent requests per instance. You want to be alerted when the average number of concurrent requests per instance exceeds 8 for at least 1 minute. Which metric and condition type should you use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "least"
Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.
Option A is correct because the `run.googleapis.com/request_count` metric tracks the number of concurrent requests per instance, which directly matches the requirement. A Metric Threshold condition with a threshold of >8 triggers an alert when the average exceeds 8 for at least 1 minute, aligning with the specified criteria.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
Change rate detects spikes in rate, not absolute concurrency level.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between metric types and condition types, where candidates confuse Metric Threshold (for sustained high values) with Change Rate (for sudden spikes) or Metric Absence (for missing data), leading to incorrect selections.
Detailed technical explanation
How to think about this question
The `run.googleapis.com/request_count` metric in Cloud Monitoring is a gauge metric that reports the current number of concurrent requests per instance, sampled every 60 seconds. When configuring a Metric Threshold condition, the alignment period and duration window must be set to 1 minute to match the requirement; the threshold of >8 ensures the alert fires when the average exceeds 80% of the maximum concurrency of 10, a common best practice to avoid instance overload and potential 429 errors.
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.

What is the correct answer to this question?
The correct answer is: Metric: run.googleapis.com/request_count, Condition type: Metric Threshold, Threshold: >8 — Option A is correct because the `run.googleapis.com/request_count` metric tracks the number of concurrent requests per instance, which directly matches the requirement. A Metric Threshold condition with a threshold of >8 triggers an alert when the average exceeds 8 for at least 1 minute, aligning with the specified criteria.
