Question
A network engineer needs to deploy an AWS Network Firewall firewall into an existing AWS environment. The environment consists of the following:
- A transit gateway with all VPCs attached to it
- Several hundred application VPCs
- A centralized egress internet VPC with a NAT gateway and an internet
gateway
- A centralized ingress internet VPC that hosts public Application Load
Balancers
- On-premises connectivity through an AWS Direct Connect gateway
attachment The application VPCs have workloads deployed across multiple Availability Zones in private subnets with the VPC route table s default route (0.0.0.0/0) pointing to the transit gateway. The Network Firewall firewall needs to inspect east-west (VPC-to-VPC) traffic and north-south (internet-bound and on-premises network) traffic by using Suricata compatible rules. The network engineer must deploy the firewall by using a solution that requires the least possible architectural changes to the existing production environment. Which combination of steps should the network engineer take to meet these requirements? (Choose three.)
Options
- ADeploy Network Firewall in all Availability Zones in each application VPC.
- BDeploy Network Firewall in all Availability Zones in a centralized inspection VPC.
- CUpdate the HOME_NET rule group variable to include all CIDR ranges of the VPCs and on-
- DUpdate the EXTERNAL_NET rule group variable to include all CIDR ranges of the VPCs and on-
- EConfigure a single transit gateway route table. Associate all application VPCs and the centralized
- FConfigure two transit gateway route tables. Associate all application VPCs with one transit
