AWS ANS-C00 Certified Advanced Networking Practice Questions 2023 - Part 16

1. Your production team had earlier created a VPC with the CIDR block of 192.168.0.0./i 6. Instances were launched in the VPC. Now there is a decision to ensure the instances have an address space for 10.0.0.0/16. How can this be achieved?

A) Launch a NAT Instance. Ensure that the instance performs Network address translation onto the CIDR range of 10.0.0.0/16
B) Change the address block of the VPC from 192.168.0.0.116 to 10.0.0.0/1 6. All of the instances will now use the new address space.
C) Create a new VPC with the address block of 10.0.0.0/16. Migrate all of the instances to the new VPC.
D) Add a new address space to the VPC. Then ensure that the instances use the new address space

What extra consideration should be in place in such a configuration?

A) Placing a NAT Instance in front of both of the VPN connections
