What Is Required to Achieve Gigabit Network Throughput on EC2

question 2

Multiple Choice

What is required to achieve gigabit network throughput on EC2? You already selected cluster-compute, 10GB instances with enhanced networking, and your workload is already network-bound, but you are not seeing 10 gigabit speeds.

• A) Enable biplex networking on your servers, so packets are non-blocking in both directions and there's no switching overhead.
• B) Ensure the instances are in different VPCs so you don't saturate the Internet Gateway on any one VPC.
• C) Select PIOPS for your drives and mount several, so you can provision sufficient disk throughput.
• D) Use a placement group for your instances so the instances are physically near each other in the same Availability Zone.
