Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
A company uses Cloud Monitoring to track the performance of their application. They want to create an alert that triggers when the 99th percentile latency exceeds 500ms over a rolling 5-minute window. Which type of SLO and alert should they use?
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
✓
Request-based SLO with window-based alert
Request-based SLOs are appropriate for latency metrics; a window-based alert evaluates over a time window. Event-based and time-based are not standard SLO types. The correct combination is request-based SLO with window-based alert.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Request-based SLO with window-based alert
Why this is correct
Request-based SLO measures performance of requests; window-based alert evaluates over a time window.
- ✗
Event-based SLO with window-based alert
Why it's wrong here
Event-based SLO is not a standard Cloud Monitoring SLO type.
- ✗
Window-based SLO with request-based alert
Why it's wrong here
SLO types are either request-based or window-based, not window-based SLO.
- ✗
Time-based SLO with event-based alert
Why it's wrong here
Time-based SLO is not a standard type; event-based alert is not commonly used for latency.
