The correct answer is AWS Firewall Manager, which enables centralized management of security group rules across accounts by allowing you to define and enforce security group policies from a single administrative account. This service works with AWS Organizations to automatically apply baseline security group rules to new and existing accounts, ensuring consistent network access controls without manual intervention. On the AWS Certified Security Specialty SCS-C02 exam, this question tests your understanding of the key difference between compliance evaluation and active enforcement—a common trap is confusing AWS Config, which only audits rules, with Firewall Manager, which actively enforces them. Remember that Service Control Policies (SCPs) govern permissions, not network traffic, and AWS Network Firewall handles packet inspection, not security group management. A helpful memory tip: think of Firewall Manager as the "enforcer" that writes the rules, while Config is just the "reporter" that checks if they are followed.
SCS-C02 Infrastructure Security Practice Question
This SCS-C02 practice question tests your understanding of infrastructure security. 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 company has a multi-account AWS environment using AWS Organizations. The security team wants to centrally manage VPC security group rules across all accounts. Which solution should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Firewall Manager to define security group policies and enforce them across accounts.
Option B is correct because AWS Firewall Manager allows centralized management of security group rules across accounts and resources. Option A is wrong because AWS Config can evaluate compliance but not enforce rules. Option C is wrong because Service Control Policies (SCPs) control permissions at the account level, not network rules. Option D is wrong because AWS Network Firewall is for network traffic inspection, not security group management.
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.
✓
Use AWS Firewall Manager to define security group policies and enforce them across accounts.
Why this is correct
Firewall Manager is designed for centralized security group management.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use AWS Organizations Service Control Policies to restrict security group modifications.
Why it's wrong here
SCPs control IAM actions, not network rules.
✗
Use AWS Config rules to automatically remediate non-compliant security groups.
Why it's wrong here
Remediation is reactive, not preventive; Firewall Manager provides proactive enforcement.
✗
Use AWS Network Firewall to inspect traffic and block unauthorized connections.
Why it's wrong here
Network Firewall is a managed firewall service, not for security group rule management.
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.
