AWS Certified Advanced Networking - Specialty (#23)

You have a global corporate network with 153 individual IP prefixes in your internal routing table. You establish a private virtual interface over AWS Direct Connect to a VPC that has an Internet gateway (IGW). All instances in the VPC must be able to route to the Internet via an IGW and route to the global corporate network via the VGW. How should you configure your on-premises BGP peer to meet these requirements?

Configure AS-Prepending on your BGP session
Summarize your prefix announcement to less than 100
Announce a default route to the VPC over the BGP session
Enable route propagation on the VPC route table
