Questions and Answers

Which of the following can be propagated to a transit gateway route table for a VPC attachment?

  • Routes in the route table associated with the connect attachment
  • Routes in the route table associated with the VPC (correct)
  • Routes in the route table associated with the transit gateway
  • Routes in the route table associated with the SD-WAN devices

What can be associated with a route table in a transit gateway?

  • VPC CIDR-blocks
  • SD-WAN appliances
  • Attachments (correct)
  • TGW route tables

Can the same attachment be associated with multiple TGW route tables?

  • Yes
  • No (correct)
  • Only if the attachment is a VPC attachment
  • Only if route propagation is enabled
