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
✓
AWS Network Firewall
Options A (AWS Network Firewall), B (Service Control Policies), and E (AWS Firewall Manager) are correct. AWS Network Firewall provides stateful inspection to filter traffic across VPCs. Service Control Policies (SCPs) centrally manage permissions and enforce guardrails across all accounts in the organization. AWS Firewall Manager centrally manages firewall rules, including AWS Network Firewall policies, across accounts. Option C (Security Groups) is incorrect because security groups are per-resource and cannot be centrally managed across accounts. Option D (AWS Config) is incorrect because AWS Config is for compliance monitoring and auditing, not for enforcing network security policies.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
AWS Network Firewall
Why this is correct
AWS Network Firewall provides stateful, managed network firewall service that can be centrally deployed across VPCs and accounts via AWS Firewall Manager.
- ✓
Service Control Policies (SCPs)
Why this is correct
Service Control Policies (SCPs) allow you to centralize control over the maximum available permissions for all accounts in your organization, ensuring guardrails.
- ✗
Security Groups
Why it's wrong here
Security Groups are per-resource virtual firewalls; they require separate configuration each time and are not centrally managed.
- ✗
AWS Config
Why it's wrong here
AWS Config is a service that enables you to assess, audit, and evaluate the configurations of your AWS resources; it is not used for active enforcement of network policies.
- ✓
AWS Firewall Manager
Why this is correct
AWS Firewall Manager simplifies your administration by providing a single service to configure firewall rules across accounts and resources, including AWS Network Firewall, AWS WAF, and Shield Advanced.
