You have multiple Amazon EC2 instances running in various clusters within the same region.
How will you ensure that the EC2 instances will communicate between the clusters without any bandwidth restrictions and also perform with the highest network performance, low latency, and low jitter?

A. B. C. D. E. F.Answer - A, B, and D.
Option A is CORRECT because Cluster placement groups are recommended for applications that benefit from low network latency, high network throughput, or both.
The majority of the network traffic is between the instances in the group.
Option B is CORRECT because Enhanced networking uses single root I/O virtualization (SR-IOV) to provide high-performance networking capabilities on supported instance types.
Option C is incorrect because it is recommended to use HVM AMIs for better performance than PV AMIs.
D.
Option D is CORRECT because HVM AMIs are presented with a fully virtualized set of hardware and boot by executing the master boot record of the root block device of your image.
This virtualization type provides the ability to run an operating system directly on top of a virtual machine without any modification as if it were run on the bare-metal hardware.
The Amazon EC2 host system emulates some or all of the underlying hardware presented to the guest.
HVM guests can take advantage of hardware extensions that provide fast access to the underlying hardware on the host system.
Option E is incorrect because using Amazon Linux does not necessarily improve any performance.
Option F is incorrect because if we enable a VPC Endpoint connection from a VPC EC2 instance to other AWS services, then the users experience slowness.

http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking.htmlLinux Amazon Machine Images use one of two types of virtualization: paravirtual (PV) or hardware virtual machine (HVM)
The main difference between PV and HVM AMIs is the way in which they boot and whether they can take advantage of special hardware extensions (CPU, network, and storage) for better performance.
We recommend that you use current generation instance types and HVM AMIs when you launch your instances for the best performance.

http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/virtualization_types.htmlTo ensure that the EC2 instances will communicate between the clusters with high network performance, low latency, and low jitter, and without any bandwidth restrictions, the recommended solution is to use a Cluster placement group.
A Cluster placement group is a logical grouping of instances within a single Availability Zone (AZ) that allows for low-latency, high-bandwidth connections between instances. The instances in a placement group are placed on hardware that is physically close together, which minimizes network latency and jitter, and maximizes network throughput.
By using a Cluster placement group, you can ensure that your EC2 instances are co-located and can communicate with each other over a high-speed, low-latency network. This is particularly important for applications that require high network performance and low latency, such as distributed databases, high-performance computing, and real-time analytics.
Enhanced networking is another option to improve network performance, which utilizes SR-IOV (Single Root I/O Virtualization) to provide higher bandwidth, lower latency, and lower CPU utilization for network-intensive workloads. However, this option doesn't provide any guarantees on placement of instances within a region, as a cluster placement group does.
Amazon PV AMI and Amazon HVM AMI are different virtualization types available for EC2 instances, and they don't provide any direct impact on networking performance between clusters.
Amazon Linux is a popular operating system that can be used on EC2 instances, but it doesn't provide any specific optimization for inter-cluster communication.
Finally, Amazon VPC Endpoints is a service that enables private connectivity between VPCs and other AWS services without using public IP addresses. While this service can improve network security and reduce data transfer costs, it doesn't provide any guarantees on network performance or placement of instances within a region.
