Topic 1 Question 74
You are responsible for the reliability of a high-volume enterprise application. A large number of users report that an important subset of the application's functionality
" a data intensive reporting feature" is consistently failing with an HTTP 500 error. When you investigate your application's dashboards, you notice a strong correlation between the failures and a metric that represents the size of an internal queue used for generating reports. You trace the failures to a reporting backend that is experiencing high I/O wait times. You quickly fix the issue by resizing the backend's persistent disk (PD). How you need to create an availability Service Level Indicator (SLI) for the report generation feature. How would you define it?As the I/O wait times aggregated across all report generation backends
As the proportion of report generation requests that result in a successful response
As the application's report generation queue size compared to a known-good threshold
As the reporting backend PD throughout capacity compared to a known-good threshold

The question is: "create an availability SLI for the report generation feature." => availability.
B is correct. Others aren't availability SLI.
👍 17NXD2021/10/31B is correct, availability = good time/ total time.
👍 6Shasha12021/11/10Answer : B. the proportion of report generation requests that result in a successful response
Question: create an AVAILABILITY SLI for the report generation feature
According to SRE Workbook, one of potential SLI is as below:
- Type of service: Request-driven
- Type of SLI: Availability
- Description: The proportion of requests that resulted in a successful response.
