Exam Professional Cloud DevOps Engineer topic 1 question 145 discussion

If the service has exceeded its error budget for the preceding four-week window, we will halt all changes and releases other than P01 issues or security fixes until the service is back within its SLO. https://sre.google/workbook/error-budget-policy/#:~:text=If%20the%20service%20has,exceed%20the%20error%20budget..

Choosing (option B) aligns with Site Reliability Engineering (SRE) principles, emphasizing the importance of maintaining system reliability and availability. By notifying the team that the error budget has been exhausted, the SRE team is proactively communicating the potential risks associated with launching the new feature during a period of heightened error rates. The suggestion to negotiate for a launch freeze or tolerate a slightly degraded user experience demonstrates a commitment to preserving the system's reliability and ensuring that user impact is minimized. This approach fosters a collaborative effort between the SRE team and the product team, allowing for informed decision-making that prioritizes reliability over feature deployment when necessary, adhering to the core tenets of SRE practices.

Vote B

This is SRE-friendly approach.

Only B seems to make a bit sense although I don't like the idea to tolerate a worse user experience.

Negotiate with the team for a launch freeze or tolerate a slightly worse user experience.

Answer C seems to be correct per Google docs: https://sre.google/workbook/error-budget-policy/
