Your team is writing a postmortem after an incident on your external facing application Your team wants to improve the postmortem policy to include triggers that indicate whether an incident requires a postmortem Based on Site Reliability Engineenng (SRE) practices, what triggers should be defined in the postmortem policy?

Choose 2 answers

Suggested Answer: A, C

The best options for defining triggers that indicate whether an incident requires a postmortem based on Site Reliability Engineering (SRE) practices are an external stakeholder asks for a postmortem and data is lost due to an incident. An external stakeholder is someone who is affected by or has an interest in the service, such as a customer or a partner. If an external stakeholder asks for a postmortem, it means that they are concerned about the impact or root cause of the incident, and they expect an explanation and remediation from the service provider. Therefore, this should trigger a postmortem to address their concerns and improve their satisfaction. Data loss is a serious consequence of an incident that can affect the integrity and reliability of the service. If data is lost due to an incident, it means that there was a failure in the backup or recovery mechanisms, or that there was a corruption or deletion of data. Therefore, this should trigger a postmortem to investigate the cause and impact of the data loss, and to prevent it from happening again.

D seems a bit too minor for a postmortem, don’t you think?

I think C is just as important as A.

Definitely A and B! Those are crucial triggers.

B is a must, but I’m not sold on A being necessary.

Surprised that E isn't a top choice! That’s a big deal!

The monitoring system detecting a failure seems like a clear trigger too. I practiced a question where we had to identify incident severity based on monitoring alerts.

I’m a bit confused about whether internal requests are as significant as external ones. I feel like both should matter, but I can't recall the specifics.

I think data loss definitely warrants a postmortem, it’s a critical incident. I’ve seen similar questions where data integrity was a key focus.

I remember discussing how external stakeholder requests can be a strong trigger for a postmortem, but I'm not sure if that's the only factor we should consider.

I feel pretty confident about this question. The SRE practices emphasize learning from incidents, so the triggers should capture the kinds of issues that warrant a deeper dive through a postmortem. Data loss and pipeline rollbacks seem like clear choices.

This is a good one. I'd say the key is to focus on triggers that indicate a significant incident or disruption to the external-facing application. Things like external stakeholder requests and internal stakeholder requests seem like they'd be good to include.
VA

Okay, I think I've got this. Based on SRE, we'll want to include triggers like data loss, failed instances, and issues detected by the CD pipeline. Those seem like the kinds of high-impact incidents that would require a deeper analysis through a postmortem.
YO

Hmm, I'm a bit unsure about this one. I know we want to include triggers based on SRE practices, but I'm not totally clear on what those would be. Maybe I should review some SRE principles before answering.

This seems like a straightforward question about defining triggers for a postmortem policy. I think the key is to focus on SRE practices and what kinds of incidents would warrant a postmortem.

Ha, I bet the answer is D and E. Gotta love those SRE practices - if the monitoring system and the CD pipeline catch something, you know it's serious business.

Wait, is this a trick question? I feel like the obvious answers are B and C - data loss and an internal stakeholder request. Who cares what the external stakeholders think, am I right?
CH
Chaya 1 year ago
Hmm, I think the triggers should be more about the impact of the incident, not just who requests it. I'd say B and D are the way to go - data loss and failed instances seem like clear reasons to do a postmortem.

I believe E should also be included as a trigger. Rolling back a release due to an issue is a significant event that requires analysis.

I agree with you, Danilo. Data loss and instance failure are critical incidents that should trigger a postmortem.

I think B and D should be defined as triggers in the postmortem policy.
