Question 2: A company’s on-premises network has an IP address range of 188.8.131.52/16. Only IPs within this network range can be used for inter-server communication. The IP address range 184.108.40.206/24 has been allocated for the cloud. A network engineer needs to design a VPC on AWS. The servers within the VPC should be able to communicate with hosts both on the internet and on-premises through a VPN connection. Which combination of configuration steps meet these requirements? (Select TWO.)
A) Set up the VPC with an IP address range of 220.127.116.11/24.
B) Set up the VPC with an RFC 1918 private IP address range (for example, 10.10.10.0/24). Set up a NAT gateway to do translation between 10.10.10.0/24 and 18.104.22.168/24 for all outbound traffic.
C) Set up a VPN connection between a virtual private gateway and an on-premises router. Set the virtual private gateway as the default gateway for all traffic. Configure the on-premises router to forward traffic to the internet.
D) Set up a VPN connection between a virtual private gateway and an on-premises router. Set the virtual private gateway as the default gateway for traffic destined to 22.214.171.124/24. Add a VPC subnet route to point the default gateway to an internet gateway for internet traffic.
E) Set up the VPC with an RFC 1918 private IP address range (for example, 10.10.10.0/24). Set the virtual private gateway to do a source IP translation of all outbound packets to 126.96.36.199/16.

A) Create a peering connection between the VPCs and update the routing tables to route traffic between the VPCs. Enable DNS resolution support for the VPC peering connection. Configure the application to connect to the DNS endpoint of the DB instance.
B) Create a gateway endpoint to the DB instance. Update the routing tables in the application VPC to route traffic to the gateway endpoint.
C) Configure a transit VPC to route traffic between the VPCs privately. Configure the application to connect to the DNS endpoint of the DB instance.
D) Create a NAT gateway in the same subnet as the EC2 instances. Update the routing tables in the application VPC to route traffic through the NAT gateway to the DNS endpoint of the DB instance.

Question 6: A company has implemented a critical environment on AWS. For compliance purposes, a network engineer needs to verify that the Amazon EC2 instances are using a specific approved security group and belong to a specific VPC.
