A. B. C. D.Answer - A and B.
The AWS Documentation mentions the following.
Enhanced networking uses single root I/O virtualization (SR-IOV) to provide high-performance networking capabilities on supported instance types.
SR-IOV is a method of device virtualization that provides higher I/O performance and lower CPU utilization when compared to traditional virtualized network interfaces.
Enhanced networking provides higher bandwidth, higher packet per second (PPS) performance, and consistently lower inter-instance latencies.
Also, when it comes to setting the MTU, you can enable Jumbo frames by setting the MTU to 9001.
Option C is incorrect since the MTU needs to be set on the Instance.
Option D is incorrect since this instance type will not support Enhanced Networking.

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking.htmlThe two answers that would help achieve maximum performance in network packet processing for an EC2 Instance responsible for processing video and audio are:
A. Ensure that the instance supports single root I/O virtualization. C. Ensure that the MTU is set to 9001 for the VP.
Explanation:
A. Ensure that the instance supports single root I/O virtualization: Single root I/O virtualization (SR-IOV) is a method of device virtualization that allows a single physical network interface to appear as multiple separate virtual devices. This approach enables high network throughput, lower latency, and reduced CPU overhead by bypassing the hypervisor and allowing direct access to the physical network interface. By ensuring that the EC2 instance supports SR-IOV, you can increase the network packet processing performance significantly.
C. Ensure that the MTU is set to 9001 for the VP: MTU stands for Maximum Transmission Unit, and it refers to the largest data packet size that can be transmitted over a network interface. By setting the MTU to 9001, the network interface can transmit larger data packets, which can help reduce the number of packets needed to transfer a given amount of data. This can help improve the network performance of the EC2 instance and reduce the overhead associated with packet processing.
D. Choose a t2.medium instance type: Choosing a t2.medium instance type may not be the best approach for achieving maximum performance in network packet processing. While t2.medium instances are a good choice for many workloads, they may not provide the level of performance required for high-volume video and audio processing. Therefore, this option is not correct.
B. Ensure that the MTU is set to 9001 on the Instance: Setting the MTU to 9001 on the EC2 instance itself may not be sufficient to achieve maximum performance in network packet processing. The MTU must also be set to 9001 for the virtual private network ( VPN) that connects the EC2 instance to other resources. Therefore, this option is not correct.
