PCDOE Managing service incidents Practice Question
This PCDOE practice question tests your understanding of managing service incidents. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following are essential elements of a comprehensive incident post-mortem document according to Google's Site Reliability Engineering (SRE) best practices?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A timeline of events leading to and during the incident.
Option B is correct because a timeline of events is a core element of an incident post-mortem in Google SRE practice, as it provides a chronological reconstruction of the incident's progression, enabling teams to understand the sequence of failures and responses. This timeline is essential for identifying contributing factors and evaluating the effectiveness of mitigation actions, not just the root cause.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Exact code line numbers and commits that caused the incident.
Why it's wrong here
Too detailed; focus on systemic issues.
✓
A timeline of events leading to and during the incident.
Why this is correct
Timeline helps understand sequence.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
A detailed analysis of the root cause only.
Why it's wrong here
Also need impact and response.
✗
An attribution of blame to the individual or team responsible.
Why it's wrong here
Blameless culture is key.
✓
A list of action items with owners and deadlines to prevent recurrence.
Why this is correct
Actionable steps improve reliability.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that a post-mortem is solely about finding the root cause or assigning blame, but SRE best practices emphasize a blameless culture and a comprehensive review that includes a timeline and actionable follow-ups.
Detailed technical explanation
How to think about this question
In Google SRE, a post-mortem document typically includes a detailed timeline with timestamps from monitoring systems (e.g., Prometheus alerts, Stackdriver logs) and human actions, which helps correlate system behavior with operator responses. This timeline is critical for identifying latency in detection or response, such as when a paging alert was delayed due to a misconfigured threshold, which a root cause analysis alone would miss. Real-world incidents often involve multiple cascading failures, and the timeline reveals the order of events that led to the final outage, enabling teams to implement targeted fixes like adding circuit breakers or improving runbooks.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
