PCDOE Implementing service monitoring strategies Practice Question
A DevOps team is setting up SLOs for a service with two critical metrics: availability and latency. They want to measure over a 30-day window. Which approach correctly defines an SLO?
⚠ Common exam trap
Google Cloud often tests the distinction between deprecated services (Stackdriver) and current ones (Cloud Monitoring), and the requirement for a rolling window versus a fixed window, leading candidates to pick D if they are unaware of deprecation or misunderstand window types.

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 Cloud Monitoring to create a custom SLI based on request latency metrics and set an SLO with a 30-day rolling window
It uses Cloud Monitoring to create a custom SLI based on request latency metrics, which is a valid SLI type, and sets an SLO with a 30-day rolling window, matching the requirement. Cloud Monitoring's SLO feature natively supports rolling windows, and latency is a standard metric for defining service-level objectives.
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 Cloud Monitoring to create a custom SLI based on logs and set an SLO with a 7-day rolling window
Why it's wrong here
The window should be 30 days, not 7.
- ✗
Use Cloud Tasks to schedule a cron job that calculates availability
Why it's wrong here
Cloud Tasks is for task execution, not SLO definition.
- ✓
Use Cloud Monitoring to create a custom SLI based on request latency metrics and set an SLO with a 30-day rolling window
Why this is correct
This correctly uses Cloud Monitoring and a 30-day rolling window.
- ✗
Use Stackdriver Monitoring (deprecated) to set an SLO with a fixed 30-day window
Why it's wrong here
Stackdriver is deprecated; use Cloud Monitoring with rolling window.
