A development team is building a new web application in the AWS Cloud. The main company domain, example.com. is currently hosted in an Amazon Route 53 public hosted zone in one of the company's production AWS accounts.
The developers want to test the web application in the company's staging AWS account by using publicly resolvable subdomains under the example.com domain with the ability to create and delete DNS records as needed. Developers have full access to Route 53 hosted zones within the staging account, but they are prohibited from accessing resources in any of the production AWS accounts.
Which combination of steps should a network engineer take to allow the developers to create records under the example.com domain? (Select TWO.)
A company recently implemented a security policy that prohibits developers from launching VPC network infrastructure. The policy states that any time a NAT gateway is launched in a VPC, the company's network security team must immediately receive an alert to terminate the NAT gateway. The network security team needs to implement a solution that can be deployed across AWS accounts with the least possible administrative overhead. The solution also must provide the network security team with a simple way to view compliance history.
Which solution will meet these requirements?
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.
