This PCDOE practice question tests your understanding of managing service incidents. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
A team defines an SLO of 99.9% availability over a 30-day window. They use a multi-window, multi-burn-rate alerting approach. Which alerting condition should trigger a page based on fast burn rate?
1% error budget consumed in 1 hour.
Why wrong: This is a moderate burn rate; may not require immediate page.
10% error budget consumed in 1 hour.
Why wrong: 10% in 1 hour is still fast but 2% in 10 minutes is faster.
2% error budget consumed in 10 minutes.
This is a fast burn rate, consuming budget quickly; should trigger a page.
5% error budget consumed in 6 hours.
Why wrong: This is a slow burn rate; may be handled by lower-severity alert.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
2% error budget consumed in 10 minutes.
Option C is correct because a multi-window, multi-burn-rate alerting approach uses a short window (e.g., 10 minutes) to detect fast burn rates that could rapidly exhaust the error budget. Consuming 2% of the error budget in 10 minutes corresponds to an annualized burn rate of over 1000x, which is dangerously fast and requires immediate paging to prevent a breach of the 99.9% SLO over the 30-day window.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
1% error budget consumed in 1 hour.
Why it's wrong here
This is a moderate burn rate; may not require immediate page.
10% error budget consumed in 1 hour.
Why it's wrong here
10% in 1 hour is still fast but 2% in 10 minutes is faster.
2% error budget consumed in 10 minutes.
Why this is correct
This is a fast burn rate, consuming budget quickly; should trigger a page.
Related concept

5% error budget consumed in 6 hours.
Why it's wrong here
This is a slow burn rate; may be handled by lower-severity alert.
Common exam traps
Google Cloud often tests the distinction between burn rate thresholds and time windows, where candidates mistakenly associate a larger percentage consumed (like 10% or 5%) with fast burn, without considering the window duration and the resulting annualized burn rate.
Detailed technical explanation
In multi-window, multi-burn-rate alerting, the fast-burn window is typically set to a very short duration (e.g., 10 minutes) with a high burn-rate threshold (e.g., 14.4x or higher) to catch sudden spikes. The 2% in 10 minutes example translates to a burn rate of 14.4x (since 2% in 10 minutes = 12% per hour, and 12% per hour * 24 hours = 288% per day, which is 2.88x the daily budget, but annualized it's far higher). This ensures that even a brief outage that would exhaust the entire error budget in under 2 hours triggers an immediate page, preventing a cascading SLO violation.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
