- A
Delete the Lambda function
This removes the malicious code.
- B
Review and remove any CloudWatch Events triggers
Removes event sources that could invoke the function.
- C
Revoke any IAM roles associated with the function
Prevents further abuse of permissions.
- D
Disable CloudTrail logging in the affected region
Why wrong: Disabling logging would hinder investigation and is not eradication.
- E
Place the function in a quarantine VPC
Why wrong: Quarantine is containment, not eradication.

CCSP Cloud Security Operations Practice Question
This CCSP practice question tests your understanding of cloud security operations. 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 cloud incident response, the security team needs to eradicate a malicious Lambda function that was created by an attacker. Which THREE steps should be part of the eradication process? (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
✓
Delete the Lambda function
Deleting the Lambda function is a direct eradication step because it removes the attacker's malicious code from the AWS environment. Once deleted, the function can no longer be invoked, and any associated execution logs or metrics will cease. This action is irreversible and ensures the attacker's foothold is eliminated.
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
Cisco often tests the misconception that placing a resource in a quarantine network (like a VPC) is sufficient for containment, but in serverless environments, the function's code and execution permissions remain active, so deletion and role revocation are mandatory.
Detailed technical explanation
How to think about this question
Lambda functions are stateless and ephemeral, but they can be triggered by various event sources (e.g., S3, DynamoDB Streams, API Gateway). During eradication, it is critical to remove all triggers (like CloudWatch Events) to prevent automatic re-invocation after deletion. Additionally, revoking IAM roles is essential because the role's permissions could be used by other compromised resources or to create new functions; AWS IAM roles are not automatically deleted when the function is deleted, so manual revocation is required.
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 SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.
