SCS-C02 Management and Security Governance Practice Question

This SCS-C02 practice question tests your understanding of management and security governance. 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.

A security engineer is designing a solution to automatically remediate noncompliant EC2 security groups. The company uses AWS Organizations with multiple accounts. The engineer wants to deploy an AWS Config rule and a custom Lambda function in a central security account to evaluate and remediate security groups across all accounts. Which combination of steps is REQUIRED to allow the Lambda function to modify security groups in member accounts? (Choose TWO.)

A
Create an IAM role in each member account that allows the central security account to assume it.
This enables cross-account access for the Lambda function to modify security groups.
B
Use AWS CloudFormation StackSets to deploy the Lambda function to all member accounts.
Why wrong: This still requires per-account remediation setup, not central.
C
Configure an AWS Config remediation action that invokes the Lambda function in the central account.
Config remediation can invoke a Lambda function cross-account if permissions are set up correctly.
D
Attach a resource-based policy to the Lambda function granting access to Config from all member accounts.
Why wrong: Config invokes Lambda via a service-linked role, not resource-based policy cross-account.
E
Create the Lambda function in each member account and configure Config rules in each account.
Why wrong: This is operationally inefficient; the goal is central management.

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 IAM role in each member account that allows the central security account to assume it.

The correct approach is to use AWS Config aggregated rules with remediation actions that invoke Lambda cross-account. Option A is required to allow the central account to assume a role in member accounts; Option C is required to invoke the Lambda function from Config. Option B (same account) is not cross-account. Option D is not required because Config aggregates can work with individual accounts. Option E is redundant.

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

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

How to think about this question

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.

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.
Use explanations to understand the rule behind the answer.

TExam Day Tips

Underline the problem statement mentally.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
