A company has an internal web-based application that employees use. The company hosts the application over a VPN in the company's on-premises network. The application runs on a fleet of Amazon EC2 instances in a private subnet behind a Network Load Balancer (NLB) in the same subnet. The instances are in an Amazon EC2 Auto Scaling group.
During a recent security incident, SQL injection occurred on the application. A network engineer must implement a solution to prevent SQL injection attacks in the future.
Which combination of steps will meet these requirements? (Select THREE.)
A company has a transit gateway in AWS Account A. The company uses AWS Resource Access Manager (AWS RAM) to share the transit gateway so that users in other accounts can connect to multiple VPCs in the same AWS Region. AWS Account B contains a VPC (10.0.0.0/16) with subnet 10.0.0.0/24 in the us-west-2a Availability Zone and subnet 10.0.1.0/24 in the us-west-2b Availability Zone. Resources in these subnets can communicate with other VPCs.
A network engineer creates two new subnets: 10.0.2.0/24 in the us-west-2b Availability Zone and 10.0.3.0/24 in the us-west-2c Availability Zone. All the subnets share one route table. The default route 0.0.0.0/0 is pointing to the transit gateway. Resources in subnet 10.0.2.0/24 can communicate with other VPCs, but resources in subnet 10.0.3.0/24 cannot communicate with other VPCs.
What should the network engineer do so that resources in subnet 10.0.3.0/24 can communicate with other VPCs?
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.
