A company has two on-premises data center locations. There is a company-managed router at each data center. Each data center has a dedicated AWS Direct Connect connection to a Direct Connect gateway through a private virtual interface. The router for the first location is advertising 110 routes to the Direct Connect gateway by using BGP, and the router for the second location is advertising 60 routes to the Direct Connect gateway by using BGP. The Direct Connect gateway is attached to a company VPC through a virtual private gateway. A network engineer receives reports that resources in the VPC are not reachable from various locations in either data center. The network engineer checks the VPC route table and sees that the routes from the first data center location are not being populated into the route table. The network engineer must resolve this issue in the most operationally efficient manner. What should the network engineer do to meet these requirements?

Chose B1
There is a route limit (100 routes) for propagation from Direct Connect gateway to a VPC via virtual private gateway. The first data center is advertising 110 routes, so they are not being propagated. Solution: Summarize routes to reduce the number below the limit. Why not others: A: Unnecessary redesign C: Cannot increase this limit D: Overkill for this issue

Option B) - You can announce a maximum of 100 prefixes to AWS.These routes can be automatically be propagated into subnet route tables • In order to advertise more than 100 prefixes, you should summarize the prefixes into larger range to reduce number of prefixes
