ANS-C01 Network Design Practice Question
A company is migrating its on-premises data center to AWS. The network team needs to extend the on-premises network to the cloud and support IP multicast traffic between environments. Which AWS service or feature should be used?
⚠ Common exam trap
A common mix-up: candidates assume Direct Connect or VPN can carry multicast traffic natively, but AWS does not forward multicast over these connections without Transit Gateway multicast or a third-party overlay solution.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Transit Gateway with multicast support
AWS Transit Gateway with multicast support is the correct choice because it is the only AWS service that natively supports IP multicast traffic between VPCs and on-premises networks. It allows you to create multicast domains and associate subnets, enabling multicast sources and receivers to communicate across attached networks, including on-premises via AWS Direct Connect or Site-to-Site VPN.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Direct Connect with a private virtual interface
Why it's wrong here
Direct Connect does not inherently support multicast; it requires Transit Gateway multicast.
- ✗
Site-to-Site VPN connection
Why it's wrong here
VPN does not support multicast.
- ✓
AWS Transit Gateway with multicast support
Why this is correct
Transit Gateway can handle multicast traffic between VPCs and on-premises via VPN or Direct Connect.
- ✗
VPC peering connection
Why it's wrong here
VPC peering does not support multicast traffic.
