A company has multiple VPCs with subnets that use IPv4. Traffic from the VPCs to the internet uses a NAT gateway. The company wants to transition to IPv6.
A network engineer creates multiple IPv6-only subnets in an existing testing VPC. The network engineer deploys a new Amazon EC2 instance that has an IPv6 address into one of the subnets. During testing, the network engineer discovers that the new EC2 instance is not able to communicate with an IPv4-only service through the internet. The network engineer needs to enable the IPv6 EC2 instance to communicate with the IPv4-only service.
Which solution will meet this requirement?
A company is developing a new application that is deployed in multiple VPCs across multiple AWS Regions. The VPCs are connected through AWS Transit Gateway. The VPCs contain private subnets and public subnets.
All outbound internet traffic in the private subnets must be audited and logged. The company's network engineer plans to use AWS Network Firewall and must ensure that all traffic through Network Firewall is completely logged for auditing and alerting.
How should the network engineer configure Network Firewall logging to meet these requirements?
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?
