QuestionQ2

Applying site reliability engineering practices

Your company follows Site Reliability Engineering principles. You are preparing a postmortem for an incident caused by a software change that severely impacted users. You want to prevent a severe incident from occurring again in the future. What should you do?

Explanation

SRE postmortems should result in blameless, concrete preventative action items that improve systems and processes. Requiring successful pre-release execution of test cases that detect the relevant error type directly reduces the likelihood that the same software-change failure reaches users. Google SRE guidance recommends preventative fixes and emphasizes that changing automated systems and processes is more reliable than trying to change human behavior.
