- A
Reboot the instance to clear any malicious processes.
Why wrong: Rebooting destroys volatile memory evidence; should not be done before memory capture.
- B
Delete the CloudTrail logs that show the instance's API calls.
Why wrong: Deleting CloudTrail logs removes API call history, destroying valuable evidence.
- C
Create an Amazon EBS snapshot of the instance's root volume.
Correct: A snapshot captures the disk state, preserving file system artifacts for offline analysis.
- D
Capture the instance's memory using a tool like LiME or Amazon EC2 instance memory capture.
Correct: Memory capture preserves running processes and in-memory evidence that would be lost on shutdown.
- E
Terminate the instance to stop the attack immediately.
Correct: After preserving evidence, terminating the instance stops the attack, preventing further resource abuse.
SCS-C02 Amazon EBS snapshot Practice Question
This SCS-C02 practice question tests your understanding of threat detection and incident response. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: amazon EBS snapshot. 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 security incident where an EC2 instance was used to launch an outbound denial-of-service (DoS) attack. The engineer needs to collect forensic evidence. Which THREE actions should the engineer take? (Choose three.)
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 an Amazon EBS snapshot of the instance's root volume.
Option C is correct because creating an Amazon EBS snapshot preserves persistent data for offline analysis. Option D is correct because capturing memory preserves volatile evidence. Option E is correct because after collecting forensic evidence, terminating the instance stops the attack immediately and prevents further damage. Options A and B are incorrect because they destroy evidence (reboot clears memory, deletion removes logs).

Common exam traps
Common exam trap: answer the scenario, not the keyword
A common pitfall is selecting options like rebooting (A) or deleting logs (B) which destroy evidence. While terminating (E) is a valid containment step, it must be done after evidence is collected via snapshot (C) and memory capture (D). The three correct actions are C, D, and E.
Detailed technical explanation
How to think about this question
Under the hood, EBS snapshots are point-in-time copies stored in Amazon S3, using incremental block-level changes to minimize storage and time. For memory capture, tools like LiME (Linux Memory Extractor) load a kernel module to dump RAM to a file, while AWS's EC2 instance memory capture uses the Nitro hypervisor to snapshot memory without requiring guest OS cooperation. In a real DoS scenario, the attacker may have used a kernel rootkit that only resides in memory, making a memory dump essential to identify the attack vector.

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.

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. Amazon EBS snapshot Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
