ANS-C01 Network Implementation Practice Question
A company is migrating a legacy application to AWS. The application requires multicast traffic between EC2 instances. Which AWS service can support multicast within a VPC?
⚠ Common exam trap
Test-takers frequently assume 'VPC native multicast' exists because of the term 'native' or confuse multicast with broadcast or unicast features, but AWS VPC does not support multicast natively, and Transit Gateway is the required service.

Correct answer & explanation
✓
Transit Gateway with multicast domain
AWS Transit Gateway supports multicast traffic through the creation of a multicast domain, which allows EC2 instances in different VPCs or subnets to send and receive multicast traffic. This is the only native AWS service that supports multicast within a VPC environment, making it the correct choice for migrating a legacy application that requires multicast.
