Master Amazon AWS Certified Advanced Networking - Specialty ANS-C01: Your Gateway to Network Supremacy
A company is migrating its on-premises network from its data center in Virginia to its data center in New York. The AWS Direct Connect connections for the Virginia and New York data center locations are both associated to the us-east-1 Region. The company needs to migrate a private VIF on an existing Direct Connect hosted connection from Virginia to New York. The company's on-premises network uses the connection to access VPCs through a Direct Connect gateway in us-east-1.
The company has already requested a new Direct Connect hosted connection from the new data center to the New York Direct Connect location.

A network engineer needs to improve the network security of an existing AWS environment by adding an AWS Network Firewall firewall to control internet-bound traffic. The AWS environment consists of five VPCs. Each VPC has an internet gateway. NAT gateways, public Application Load Balancers (ALBs), and Amazon EC2 instances. The EC2 instances are deployed in private subnets. The architecture is deployed across two Availability Zones.
The network engineer must be able to configure rules for the public IP addresses in the environment, regardless of the direction of traffic. The network engineer must add the firewall by implementing a solution that minimizes changes to the existing production environment. The solution also must ensure high availability.
Which combination of steps should the network engineer take to meet these requirements? (Select TWO.)
Correct : C, D
