The correct answer is to restore the VM from a recent snapshot or backup provided by the cloud provider. This is the best course of action because when a cloud VM is terminated, its ephemeral instance store and local disks are immediately destroyed, making direct recovery impossible; however, persistent snapshots and backups capture the disk state at a specific point in time, preserving the file system, application data, and user artifacts needed for forensic analysis. On the CHFI exam, this scenario tests your understanding of cloud forensic acquisition methods, specifically the distinction between ephemeral and persistent storage in environments like AWS, Azure, or GCP—a common trap is assuming you can recover data from the terminated instance itself or from metadata alone. Remember the memory tip: “Terminated VM? Snapshots are your friend—ephemeral is gone, persistent is gold.”
CHFI Network and Cloud Forensics Practice Question
This CHFI practice question tests your understanding of network and cloud forensics. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
During a forensic investigation of a cloud environment, a forensic analyst discovers that the virtual machine (VM) used by a suspect was terminated three days prior. The cloud provider offers snapshots, backups, and instance metadata. Which of the following is the BEST course of action to recover forensic evidence?
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
✓
Restore the VM from a recent snapshot or backup provided by the cloud provider.
Option D is correct because once a VM is terminated, its underlying instance store or ephemeral disks are destroyed, but persistent snapshots and backups retain the disk state at the time they were taken. Restoring from a recent snapshot or backup is the only reliable method to recover the VM's file system, application data, and user artifacts for forensic analysis in a cloud environment.
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.
✗
Examine CloudTrail logs for disk contents.
Why it's wrong here
CloudTrail logs API calls, not disk data.
✗
Access the VM’s operating system via the cloud console’s serial console.
Why it's wrong here
Serial console is only available for running instances.
✗
Use SSH credentials from the investigation to connect to the terminated instance.
Why it's wrong here
Terminated instances are no longer running; SSH is unavailable.
✓
Restore the VM from a recent snapshot or backup provided by the cloud provider.
Why this is correct
Snapshots preserve the disk state and can be attached to a new instance for analysis.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that CloudTrail or similar audit logs contain disk-level data, leading candidates to choose option A, when in fact these logs only capture metadata and API activity, not the contents of virtual disks.
Detailed technical explanation
How to think about this question
Cloud providers like AWS, Azure, and GCP separate compute instances from storage; snapshots are point-in-time copies of block storage volumes (e.g., EBS snapshots in AWS) stored in a durable object store (e.g., S3). When a VM is terminated, the root volume is typically deleted unless termination protection or a 'Delete on Termination' flag is disabled, but snapshots and backups persist independently. Forensic analysts should also check for automated backup policies (e.g., AWS Backup, Azure Backup) that may have created recovery points even if manual snapshots were not taken.

Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
