- A
Use a forecast condition on the log-based metric to predict when errors will exceed 10
Why wrong: Forecast is for predicting future values, not for counting current errors over a window.
- B
Create a log-based counter metric and use a metric threshold condition with rolling window 5 minutes, threshold 10
Correct. Log-based counter metrics count log entries; alert threshold condition evaluates on rolling window.
- C
Use a logs-based alerting policy directly with a filter and set count > 10 in 5 minutes
Why wrong: Cloud Monitoring does not have native 'logs-based alerting' as a separate condition type; you must use a log-based metric.
- D
Create a metric threshold alert on the log entry count metric with duration 5 minutes and threshold 10
Why wrong: Duration is the time the condition must be true before firing; setting duration to 5 minutes means it must exceed threshold for 5 consecutive minutes, not total in a window.
PCDE Implementing Service Monitoring Strategies Practice Question
This PCDE practice question tests your understanding of implementing service monitoring strategies. 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.
You need to set up an alert that fires when the total number of errors in a specific Cloud Logging log view exceeds 10 in any 5-minute window over the last 1 hour. Which combination of alerting policy conditions and log-based metric is appropriate?
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
Create a log-based counter metric and use a metric threshold condition with rolling window 5 minutes, threshold 10
To count errors from logs, you create a log-based counter metric. Then set an alert with condition type 'metric threshold', using the counter metric, with aggregation window '5 minutes', and trigger if value > 10. The 'condition absent' is for missing data, not threshold. 'Forecast' predicts future values. Standard configuration: log-based counter metric + metric threshold alert.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a forecast condition on the log-based metric to predict when errors will exceed 10
Why it's wrong here
Forecast is for predicting future values, not for counting current errors over a window.
- ✓
Create a log-based counter metric and use a metric threshold condition with rolling window 5 minutes, threshold 10
Why this is correct
Correct. Log-based counter metrics count log entries; alert threshold condition evaluates on rolling window.

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.
