A media company is rendering high-resolution 3D animations. The rendering software runs on Amazon EC2 instances and requires extreme network performance and low latency between nodes. Which TWO features should the solutions architect use to maximize network performance? (Select TWO.)

Answer options:

Elastic Network Adapter (ENA)

Elastic IP Addresses (EIP)

AWS Global Accelerator

Elastic Fabric Adapter (EFA)

VPC Peering

How to approach this question

Look for the network adapters designed for high performance: ENA (Enhanced Networking) and EFA (HPC).

Full Answer

To maximize network performance for HPC or rendering workloads, you should use Enhanced Networking with the Elastic Network Adapter (ENA), which provides higher bandwidth and lower latency. For even tighter coupling, the Elastic Fabric Adapter (EFA) provides OS-bypass capabilities, drastically reducing latency for inter-node communication.

Common mistakes

Choosing Global Accelerator, which is for user-to-application traffic, not instance-to-instance traffic.
