A network engineer needs to set up an Amazon EC2 Auto Scaling group to run a Linux-based network appliance in a highly available architecture. The network engineer is configuring the new launch template for the Auto Scaling group.
In addition to the primary network interface the network appliance requires a second network interface that will be used exclusively by the application to exchange traffic with hosts over the internet. The company has set up a Bring Your Own IP (BYOIP) pool that includes an Elastic IP address that should be used as the public IP address for the second network interface.
How can the network engineer implement the required architecture?
A company uses transit gateways to route traffic between the company's VPCs. Each transit gateway has a single route table. Each route table contains attachments and routes for the VPCs that are in the same AWS Region as the transit gateway. The route tables in each VPC also contain routes to all the other VPC CIDR ranges that are available through the transit gateways. Some VPCs route to local NAT gateways.
The company plans to add many new VPCs soon. A network engineer needs a solution to add new VPC CIDR ranges to the route tables in each VPC.
Which solution will meet these requirements in the MOST operationally efficient way?
A company has an AWS account with four VPCs in the us-east-1 Region. The VPCs consist of a development VPC and three production VPCs that host various workloads.
The company has extended its on-premises data center to AWS with AWS Direct Connect by using a Direct Connect gateway. The company now wants to establish connectivity to its production VPCs and development VPC from on premises. The production VPCs are allowed to route data to each other. However, the development VPC must be isolated from the production VPCs. No data can flow between the development VPC and the production VPCs.
In preparation to implement this solution, a network engineer creates a transit gateway with a single transit gateway route table. Default route table association and default route table propagation are turned off. The network engineer attaches the production VPCs. the development VPC. and the Direct Connect gateway to the transit gateway. For each VPC route table, the network engineer adds a route to 0.0.0.0/0 with the transit gateway as the next destination.
Which combination of steps should the network engineer take next to complete this solution? (Select THREE.)
