A company has an AWS Site-to-Site VPN connection between AWS and its branch office. A network engineer is troubleshooting connectivity issues that the connection is experiencing. The VPN connection terminates at a transit gateway and is statically routed. In the transit gateway route table, there are several static route entries that target specific subnets at the branch office.
The network engineer determines that the root cause of the issues was the expansion of underlying subnet ranges in the branch office during routine maintenance.
Which solution will solve this problem with the LEAST administrative overhead for future expansion efforts?
An organization launched an IPv6-only web portal to support IPv6-native mobile clients. Front-end instances launch in an Amazon VPC associated with an appropriate IPv6 CIDR. The VPC IPv4 CIDR is fully utilized. A single subnet exists in each of two Availability Zones with appropriately configured IPv6 CIDR associations. Auto Scaling is properly configured, and no Elastic Load Balancing is used.
Customers say the service is unavailable during peak load times. The network engineer attempts to launch an instance manually and receives the following message: “There are not enough free addresses in subnet ‘subnet-12345677’ to satisfy the requested number of instances.”
What action will resolve the availability problem?
