A company runs an application on Amazon EC2 instances. A network engineer implements a NAT gateway in the application's VPC to replace self-managed NAT instances. After the network engineer shifts traffic from the self-managed NAT instances to the NAT gateway, users begin to report issues.
During troubleshooting, the network engineer discovers that the connection to the application is closing after approximately 6 minutes of inactivity.
What should the network engineer do to resolve this issue?
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 runs workloads in multiple VPCs in the us-east-1 Region. The VPCs are connected to a transit gateway. An AWS Direct Connect connection provides private connectivity between a data center that is in the US and the transit gateway. A Direct Connect gateway is associated with the transit gateway.
The company has recently opened a new office location in London. The company plans to launch cloud services in multiple VPCs in the eu-west-2 Region. Users in the new London office must have private access to the workloads that run in us-east-1. Users in the US data center must have access to any workloads that are created in eu-west-2. A network engineer must implement a flexible solution that provides users the required access. The solution must be able to accommodate future growth.
Which solution will meet these requirements with the LEAST operational effort?
