ANS-C01: AWS Network Firewall Centralized Intrusion Prevention for Multi-VPC Environments

Discover how AWS Network Firewall’s centralized deployment offers robust intrusion prevention without re-architecting. Learn how it secures multiple VPCs, spans across regions, and handles unencrypted traffic effectively.

Table of Contents


A consulting company manages AWS accounts for its customers. One of the company’s customers needs to add intrusion prevention for its environment without having to re-architect the environment. The customer’s environment includes five VPCs in two AWS Regions in the United States. VPC-to-VPC connectivity is achieved through VPC peering. The customer does not plan to increase the number of VPCs within the next 2 years. The solution must accommodate unencrypted traffic.

Which solution will meet these requirements?

A. Configure VPC security groups and network ACLs.
B. Use an AWS Network Firewall centralized deployment model in each VPC.
C. Use an AWS Network Firewall distributed deployment model in each VPC.
D. Deploy AWS Shield in each VPC.


B. Use an AWS Network Firewall centralized deployment model in each VPC.


The solution that best aligns with the requirements of adding intrusion prevention without re-architecting the environment, accommodating unencrypted traffic, and spanning across multiple VPCs in different AWS Regions, would be:

B. Use an AWS Network Firewall centralized deployment model in each VPC.

This option allows for the implementation of AWS Network Firewall in a centralized manner within each VPC. It offers intrusion prevention capabilities without the need for major restructuring. The centralized deployment model allows consistent enforcement of security policies across multiple VPCs, ensuring protection against threats while accommodating unencrypted traffic and spanning across different regions.
