PCDOE Practice Question: Applying site reliability engineering practices
A company's SRE team is designing an incident management process. They want to ensure that alerts are actionable and that on-call engineers are not overwhelmed by false positives. Which approach should they take?
⚠ Common exam trap
Google Cloud often tests the misconception that more alerts or higher thresholds equal better reliability, when in fact the key is aligning alerts with SLOs and error budgets to ensure they are actionable and reduce noise.

Correct answer & explanation
✓
Define SLOs and set alert thresholds based on historical error budget consumption
Defining SLOs and setting alert thresholds based on historical error budget consumption ensures alerts are directly tied to user-facing reliability. This approach prevents false positives by only triggering when the error budget is being consumed faster than expected, making alerts actionable and reducing noise for on-call engineers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use only critical severity alerts and rely on manual dashboard review for lower severity
Why it's wrong here
Manual review is inefficient and may miss issues.
- ✗
Create alerting policies for every available metric to ensure nothing is missed
Why it's wrong here
This would cause alert fatigue with many false positives.
- ✗
Set all alert thresholds to 50% above the average value to avoid false positives
Why it's wrong here
This may miss real issues and does not consider SLOs.
- ✓
Define SLOs and set alert thresholds based on historical error budget consumption
Why this is correct
SLO-based alerting focuses on user-facing impact and reduces noise.
