PCDOE Implementing service monitoring strategies Practice Question
You are designing SLO monitoring for a high-traffic e-commerce platform. Which three best practices should you follow? (Choose three.)
⚠ Common exam trap
Google Cloud often tests the misconception that a single, high-level SLO is sufficient for monitoring, when in reality multiple SLOs aligned to user journeys are required to detect partial outages that affect specific critical paths.
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 multiple SLOs for different critical user journeys.
Using multiple SLOs for different critical user journeys (e.g., checkout, product search, login) allows you to tailor reliability targets to the specific performance and availability needs of each workflow. This granularity prevents a single, coarse SLO from masking issues that affect only a subset of users, enabling more precise monitoring and faster incident response.
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 multiple SLOs for different critical user journeys.
Why this is correct
Separate SLOs allow targeted monitoring and alerting for each journey's requirements.
- ✓
Monitor error budgets and alert when depletion is imminent.
Why this is correct
Error budget alerts enable proactive action before SLO is breached.
- ✓
Use SLI metrics that align with user experience, like request latency and errors.
Why this is correct
SLIs should reflect what users experience; latency and error rate are common and effective.
- ✗
Use a single global SLO for all customer segments.
Why it's wrong here
Different user journeys have different reliability expectations; a single SLO is too coarse.
- ✗
Set the SLO to 100% to ensure maximum reliability.
Why it's wrong here
100% SLO is unattainable and leaves no room for error budget; industry best practice is below 100%.
