You need to set up an Amazon Elastic Compute Cloud (EC2) instance for an application that requires the lowest latency and the highest packet-per-second network performance. The application will talk to other servers in a peered VPC. Which two of the following components should be part of the design? (Choose two.)
A) Select an instance with support for single root I/O virtualization.
B) Select an instance that has support for multiple ENIs.
C) Ensure that the instance supports jumbo frames and set 9001 MTU.
D) Select an instance with Amazon Elastic Block Store (EBS)-optimization.
E) Ensure that proper OS drivers are installed.

Single root I/O virtualization (SR-IOV) allows multiple virtual functions (VFs) to share a single physical function (PF) on a network interface card (NIC). This can reduce latency and improve packet-per-second performance. Multiple ENIs can also improve network performance by providing more bandwidth and reducing congestion.
