- A
Use dd to copy the disk over SSH to a forensic workstation.
Why wrong: This can alter the disk state and is not the recommended practice for GCP forensic snapshots.
- B
Stop the instance, create a snapshot of the disk, then detach the disk.
Why wrong: Stopping the instance may alter the disk state (e.g., cache flush). Snapshot before stopping is better.
- C
Detach the disk first, then create a snapshot of the detached disk.
Why wrong: Detaching may cause the VM to crash or lose data; also the disk state at detachment might not reflect the compromise.
- D
Create a snapshot of the disk while the instance is running, then detach the disk.
This captures the current state including deleted files, and detaching prevents further modifications. Running snapshot is possible.
PCSE Practice Question: Managing Operations in a Cloud Solution Environment
This PCSE practice question tests your understanding of managing operations in a cloud solution environment. 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.
A security engineer is investigating a compromised Compute Engine VM. They need to take a forensic snapshot of the disk without losing any data, including deleted files, and ensure the snapshot is not tampered with. Which steps should they take?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create a snapshot of the disk while the instance is running, then detach the disk.
The correct approach is to first create a snapshot of the disk for forensic analysis, which captures the disk state including deleted files (unless overwritten). Then detach the disk from the instance to prevent further changes. Creating a snapshot after detaching would lose the current state. Powering off the instance may alter data. Using dd over SSH may change file access times.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
