Quick Answer
The answer is AWS Config with a managed rule to detect internet gateways and an automatic remediation action to detach them. This is correct because AWS Config continuously evaluates your VPC configurations against desired compliance rules, and when it detects an internet gateway attached to a VPC, its remediation action can automatically detach the gateway, enforcing the security team’s policy. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this scenario tests your understanding of how to combine detective controls with automated remediation in a networking context—a common trap is confusing AWS Config with GuardDuty (which focuses on threat detection) or with SCPs (which prevent future actions but don’t detect existing resources). Remember the memory tip: “Config catches, remediates, and detaches—GuardDuty hunts, SCPs block, CloudTrail logs.” This distinction is critical for passing the exam’s security and compliance domain.
This ANS-C01 practice question tests your understanding of network security, compliance and governance. 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.
A company has an AWS account with multiple VPCs. The security team wants to ensure that no VPC has an internet gateway attached. Which AWS service can be used to automatically detect and remediate non-compliant VPCs?
Amazon GuardDuty
Why wrong: GuardDuty detects threats, not configuration compliance.
AWS CloudTrail
Why wrong: CloudTrail logs API calls but does not automatically remediate.
Service control policies (SCPs)
Why wrong: SCPs prevent actions but do not detect existing non-compliance.
AWS Config with a managed rule to detect internet gateways and an automatic remediation action to detach them.
Config can detect and auto-remediate.
Answer choices

Correct answer & explanation
AWS Config with a managed rule to detect internet gateways and an automatic remediation action to detach them.
AWS Config rules can evaluate compliance and trigger remediation. Option A is correct. Option B is wrong because GuardDuty is for threat detection, not configuration compliance. Option C is wrong because SCPs prevent actions but do not detect existing resources. Option D is wrong because CloudTrail is for auditing API calls, not real-time compliance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
