20+ practice questions focused on Applying Site Reliability Engineering Practices to a Service — one of the most tested topics on the Google Professional Cloud Database Engineer exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Applying Site Reliability Engineering Practices to a Service PracticeAn SRE team wants to define an SLI for service availability. Which metric correctly represents the availability SLI?
Explanation: Availability as an SLI is measured as the proportion of successful requests to total requests. Option A correctly defines this as 'Total requests that succeed / Total requests'. Option B is incorrect because it measures latency (response time within 200 ms), not availability. Option C is a measure of uptime, not service availability from the user's perspective. Option D only counts errors, which is not a ratio.
A service has an SLO of 99.9% availability over a 30-day month. What is the error budget in minutes for that month?
Explanation: Error budget = (100% - SLO) * total time. 0.1% of 43,200 minutes (30 days) is 43.2 minutes. Rounded to 43 minutes.
An engineer needs to set up alerting for error budget burn rate. For a fast burn alert, which burn rate multiplier and evaluation window are recommended?
Explanation: Fast burn alert uses a 1-hour window and 14x burn rate. Slow burn uses 6-hour window and 5x burn rate.
A team wants to reduce toil by automating a manual process that generates a report from Cloud Logging logs and emails it weekly. Which solution is most cost-effective and requires minimal operational overhead?
Explanation: Cloud Scheduler triggers a Cloud Function or runs a query in BigQuery, but the most straightforward serverless option is a Cloud Function triggered by Cloud Scheduler. Cloud Composer is heavy for a simple report. Cloud Run requires containerization. Cloud Build is for CI/CD.
During an incident, the incident commander identifies a need to scale up a managed instance group. Which IAM role should be granted to the on-call engineer to allow them to modify the instance group?
Explanation: Compute Instance Admin (roles/compute.instanceAdmin.v1) allows full control over instances and instance groups, including modifying MIGs. Instance Admin (basic) is restricted. Compute Admin is broader but includes other resources. Security Admin does not have compute permissions.
