You use a VPN to extend your corporate network into a VPC. Instances in the VPC are able to resolve resource records in an Amazon Route 53 private hosted zone. Your on-premises DNS server is configured with a forwarder to the VPC DNS server IP address. On-premises users are unable to resolve names in the private hosted zone, although instances in a peered VPC can. What should you do to provide on-premises users with access to the private hosted zone?

A company has 20 AWS accounts and has hundreds of VPCs within those accounts. Each account has several security groups. Most of the security groups share a common set of CIDR range rules.

The company wants to simplify the management of these CIDR ranges that the security groups use. The company's network team does not have full access to all the accounts. The common CIDR ranges are 10.10.0.0/16, 10.8.0.0/16, and 192.168.128.0/24.

Which solution should a network engineer recommend to meet these requirements?
