A company has two redundant AWS Direct Connect connections to a VPC. The VPC is configured using BGP metrics so that one Direct Connect connection is used as the primary traffic path. The company wants the primary Direct Connect connection to fail to the secondary in less than one second.
What should be done to meet this requirement?

In the context of CloudFront RTMP Distribution, the Adobe Flash Media Server _________ file specifies which domains can access media files in a particular domain.

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).

How should you configure your on-premises BGP peer to meet these requirements?
