Discuss PeopleCert DevOps-SRE Exam Topic 2 Question 64

In a blameless post-mortem, those involved report

AWithout fear of retribution

BAssumptions they had made

CBoth A and B

DUsing testing data

Suggested Answer: C

Comprehensive and Detailed Explanation From Exact Extract:

A blameless post-mortem is a foundational SRE practice that encourages truthful, detailed reporting after an incident. The purpose is to learn, not punish. Google SRE emphasizes that engineers must feel psychologically safe to report what they did, what they assumed, and why they made those decisions.

From the Site Reliability Engineering Book, Chapter ''Postmortem Culture'':

''Blameless postmortems encourage engineers to share the full details of their actions and assumptions without fear of punishment, enabling learning and preventing repeated failures.''

The book further states:

''Understanding the assumptions made during an incident is critical to uncovering systemic issues.''

Thus:

Engineers must report without fear of retribution

They must report assumptions and decisions made during the incident

Therefore, the correct answer is C. Both A and B.

Why the other options are insufficient:

A Only partially correct

B Only partially correct

D Testing data may be included, but it is not the defining feature of blameless postmortems
