Exam Professional Cloud DevOps Engineer topic 1 question 74 discussion

The question is: "create an availability SLI for the report generation feature." => availability. B is correct. Others aren't availability SLI.

B is correct, availability = good time/ total time.

C and D are SLOs (they use a threshold). B seems to be more like an indicator and didn't rely exclusivelly on PD's I/O. Any issue that disturb the correct reports finalization could be detected with this SLI

option B

B is correct.

B. As the proportion of report generation requests that result in a successful response is a valid availability Service Level Indicator (SLI) for the report generation feature. This indicator measures the percentage of requests for report generation that are successfully completed, and it is an indicator of the service availability. This SLI provides a clear and measurable way to track the availability of the report generation feature. It is a simple and easy to understand metric, that it can be easily monitored and reported. It can be used to track the performance of the report generation feature over time and detect any potential issues that may cause it to become unavailable. It also allows you to detect and diagnose issues in the system quickly and take appropriate action to mitigate them. Additionally, it aligns well with the customer's expectation of the report generation feature as they want to see a high percentage of successful report generation requests, which indicates that the feature is working correctly.

B is the answer.

Answer : 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. https://sre.google/workbook/implementing-slos/

B is correct

Service Level Indicator, is a key metric used to determine whether or not the SLO is being met. To prevent overcomplicating things, it’s important to keep things simple and choose the right key metrics to monitor. Here Queue size is the key metric.

B is correct

Eliminate A, Eliminate C and D. SLI are always based on facts, not on KNOWN GOOD Answer B : good/total

B B B B is the answer!

should be D.. since the throughput and IOPS become the issue

Why not C, you already have a metric that represents the size of an internal queue

D for sure
