ANS-C01 Exam
A company plans to run a computationally intensive data processing application on AWS. The data is highly sensitive. The VPC must have no direct internet access, and the company has applied strict network security to control access.
Data scientists will transfer data from the company's on-premises data center to the instances by using an AWS Site-to-Site VPN connection. The on-premises data center uses the network range 172.31.0.0/20 and will use the network range 172.31.16.0/20 in the application VPC.
The data scientists report that they can start new instances of the application but that they cannot transfer any data from the on-premises data center. A network engineer enables VPC flow logs and sends a ping to one of the instances to test reachability. The flow logs show the following:

The network engineer must recommend a solution that will give the data scientists the ability to transfer data from the on-premises data center.
Which solution will meet these requirements?
A company's existing AWS environment contains public application servers that run on Amazon EC2 instances. The application servers run in a VPC subnet. Each server is associated with an Elastic IP address.
The company has a new requirement for firewall inspection of all traffic from the internet before the traffic reaches any EC2 instances. A security engineer has deployed and configured a Gateway Load Balancer (GLB) in a standalone VPC with a fleet of third-party firewalls.
How should a network engineer update the environment to ensure that the traffic travels across the fleet of firewalls?
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.)
