CCSP Cloud Security Operations Practice Question
This CCSP practice question tests your understanding of cloud security operations. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
An organization is implementing automated remediation for common cloud security misconfigurations using AWS Config and Lambda. Which THREE misconfigurations can be automatically remediated using this approach?
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
✓
S3 bucket with public read access
AWS Config can evaluate S3 bucket public read access against a managed rule (s3-bucket-public-read-prohibited) and trigger a Lambda function to apply a bucket policy that blocks public access. This is a common automated remediation pattern because the fix is deterministic and can be applied via the AWS SDK without manual intervention.
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 distinction between misconfigurations that can be automatically fixed without downtime (like S3 bucket policies or security group rules) versus those that require instance state changes or manual approval (like EC2 instance type or VPC default security group modifications).
Detailed technical explanation
How to think about this question
AWS Config remediation actions use SSM Automation documents or custom Lambda functions; for S3 public read, the Lambda can call put_public_access_block on the bucket. For EBS encryption, the Lambda can create an encrypted snapshot and replace the volume, but this requires the instance to be stopped, which is why it's often paired with a maintenance window. For security groups allowing SSH from 0.0.0.0/0, the Lambda can revoke the ingress rule using revoke_security_group_ingress, but this may break legitimate access if not carefully scoped.
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 developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
