PCDOE Managing service incidents Practice Question
This PCDOE practice question tests your understanding of managing service incidents. 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.
Your SLO for availability is 99.9% over a 30-day window. You want an alert that fires when the error budget burn rate is high, leaving less than 5% of the error budget remaining in the next 6 hours. What type of alerting policy should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A burn rate alert based on the forecasted consumption.
Option C is correct because a burn rate alert based on forecasted consumption directly monitors the rate at which the error budget is being consumed and triggers when the projected remaining budget falls below 5% within the next 6 hours. This aligns with Google SRE best practices for proactive error budget management, using a multi-window, multi-burn-rate approach to detect rapid consumption before the budget is exhausted.
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.
✗
A custom log-based metric.
Why it's wrong here
Log-based metrics can contribute to burn rate but are not an alerting policy type.
✗
A static threshold alert based on the error rate.
Why it's wrong here
Static thresholds do not account for budget consumption rate.
✓
A burn rate alert based on the forecasted consumption.
Why this is correct
Burn rate alerts track how fast the error budget is being used and can forecast depletion.

✗
An exponential decay alert.
Why it's wrong here
Exponential decay is not a standard alerting method for burn rate.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the distinction between static error rate thresholds and dynamic burn rate alerts, trapping candidates who think a simple error rate threshold can adequately protect an SLO without considering the time-based consumption of the error budget.
Detailed technical explanation
How to think about this question
Burn rate alerts work by comparing the actual error rate over a sliding window (e.g., 1 hour, 6 hours) to the target error rate derived from the SLO (e.g., 0.1% for 99.9% availability). A burn rate of 1 means the error budget is consumed exactly as expected; a burn rate of 2 means it is consumed twice as fast. Google SRE recommends using multiple burn rate thresholds (e.g., 2x, 10x) with corresponding alerting windows to catch both fast and slow budget depletion, ensuring the alert fires when less than 5% remains in the next 6 hours.

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
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.
