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? (Choose three.)

Chose ACF2
when the traffic from the on-prem to dev vpc, it lands on the old existing route table but that doesn't aware how to reach dev vpcs... Just selecting ACF as those are relavant.. otherwise still missing communication for the dev vpc from the on-prem

F is also incorrect, there is no reason to create a new transit gateway at all.

ACE, but the you need to propagate the Devop Routes on the existing RT, so DX and Devops can reach each other, between Prod and Devop cannot reach each other because there is not propagation for the Prod Routes en de new RT
