Q653. A company is deploying an application that processes streaming data in near-real time. The company plans to use Amazon EC2 instances for the workload. The network architecture must be configurable to provide the lowest possible latency between nodes.Which combination of network solutions will meet these requirements? (Select TWO.)

Correct Answer: A. Enable and configure enhanced networking on each EC2 instance., C. Run the EC2 instances in a cluster placement group.

Explanation

To meet the requirements of deploying an application that processes streaming data in near-real time with the lowest possible latency between nodes using Amazon EC2 instances, the following combination of network solutions would be suitable:A. Enable and configure enhanced networking on each EC2 instance.C. Run the EC2 instances in a cluster placement group.Here's the rationale behind these solutions:Option A: Enable and configure enhanced networking on each EC2 instance. Enhanced networking is a feature that provides higher packet per second (PPS) performance, lower network jitter, and lower network latency. By enabling and configuring enhanced networking on each EC2 instance, you can optimize the network performance and reduce latency between nodes.Option C: Run the EC2 instances in a cluster placement group. A cluster placement group is a logical grouping of instances within a single Availability Zone. By running the EC2 instances in a cluster placement group, you can minimize the network latency between the instances within the group. This allows for closer proximity and faster communication between the instances, further reducing latency.Option B: Group the EC2 instances in separate accounts.Grouping the EC2 instances in separate accounts does not directly address the requirement of achieving the lowest possible latency between nodes. It might be useful for organizational or security purposes but would not impact network latency.Option D: Attach multiple elastic network interfaces to each EC2 instance. Attaching multiple elastic network interfaces to each EC2 instance is not directly related to achieving the lowest possible latency between nodes. Multiple network interfaces can be useful for specific use cases, such as network traffic segregation or high availability, but they do not inherently reduce network latency.Option E: Use Amazon Elastic Block Store (Amazon EBS) optimized instance types. Amazon EBS optimized instance types are designed to provide optimized performance for Amazon EBS volumes. While they can improve the performance of storage operations, they do not directly impact network latency between EC2 instances.Therefore, enabling and configuring enhanced networking on each EC2 instance (Option A) and running the EC2 instances in a cluster placement group (Option C) would provide the best combination of network solutions to achieve the lowest possible latency between nodes for processing streaming data in near-real time.
