An SRE team wants to define an SLI for service availability. Which metric correctly represents the availability SLI?

Trap 1: Total requests that complete within 200 ms / Total requests

This is a latency SLI, not availability.

Trap 2: Total minutes the service is up / Total minutes in the window

This is a different measure (uptime), not request-based availability.

Trap 3: Number of requests that return a 5xx status code

This is an error count, not an availability ratio.

A
Total requests that succeed / Total requests
Correct definition of availability SLI.
B
Total requests that complete within 200 ms / Total requests
Why wrong: This is a latency SLI, not availability.
C
Total minutes the service is up / Total minutes in the window
Why wrong: This is a different measure (uptime), not request-based availability.
D
Number of requests that return a 5xx status code
Why wrong: This is an error count, not an availability ratio.

Applying Site Reliability Engineering Practices to a Service questions

An SRE team wants to define an SLI for service availability. Which metric correctly represents the availability SLI?

A service has an SLO of 99.9% availability over a 30-day month. What is the error budget in minutes for that month?

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?

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?

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?

A service has an SLO based on request latency: 99% of requests must complete under 500ms over a 28-day window. The team wants to monitor the error budget burn rate. Which Cloud Monitoring SLO type and configuration should be used?

Which of the following best describes 'toil' in SRE?

A team wants to implement chaos engineering on Google Kubernetes Engine (GKE) to test resilience against pod failures. Which tool is designed for injecting faults into GKE clusters?

An SRE team uses Cloud Monitoring SLOs with an error budget policy. They want to receive an alert when the error budget is exhausted at a rate that would exhaust it in 1 hour (fast burn). The SLO is 99.9% over 30 days. The error budget is 43.2 minutes. What burn rate threshold should be used?

During a blameless postmortem, the team uses the '5 Whys' technique to identify root causes. What is the primary purpose of this technique?

A company wants to implement a service mesh with fault injection for HTTP services running on Google Kubernetes Engine. They need to inject artificial delays and errors into requests to test resilience. Which GCP service should they use?

An SRE team defines an SLO for a batch processing pipeline. Which SLI is most appropriate for pipeline freshness?

Which TWO components are essential for setting up an incident management on-call rotation in Google Cloud? (Choose 2)

Which THREE are key principles of a blameless postmortem culture in SRE? (Choose 3)

Which TWO metrics are appropriate for defining a request-based SLI for a web service? (Choose 2)

A site reliability engineer is defining an SLO for a service that processes user uploads. The team wants to measure success as the proportion of uploads completed within 2 seconds. Which type of SLI should they use?

A team's SLO for availability is 99.9% over a 30-day window. They have consumed 80% of their error budget halfway through the month. What is the remaining allowed downtime for the rest of the month?

You are configuring error budget burn rate alerts for an SLO with a 30-day window. The SLO target is 99.9%. You want to alert if the error budget is projected to be fully consumed in 2 hours, using a fast burn rate. Which alerting policy configuration should you use?

An SRE team wants to reduce toil associated with manual database schema migrations. They currently run SQL scripts manually during maintenance windows. Which Google Cloud service is most appropriate to automate this process in a repeatable way?

During a blameless postmortem after an incident, the team identified that the root cause was a misconfigured load balancer health check. Which practice should the team prioritize to prevent recurrence?
