Question #: 746
Topic #: 1

[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

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? (Choose two.)

A. Enable and configure enhanced networking on each EC2 instance.
B. Group the EC2 instances in separate accounts.
C. Run the EC2 instances in a cluster placement group.
D. Attach multiple elastic network interfaces to each EC2 instance.
E. Use Amazon Elastic Block Store (Amazon EBS) optimized instance types.

Selected Answer: AC

A. Enable and configure enhanced networking on each EC2 instance. Enhanced networking provides higher bandwidth, higher packet per second (PPS) performance, and consistently lower inter-instance latencies. 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. This configuration is recommended for applications that need low network latency, high network throughput, or both.

Selected Answer: AC

To reach speeds up to 10 Gbps between instances, launch your instances in a cluster placement group with the enhanced networking instance type. These instance types are placed physically close to each other. Instance types that are close to each other further reduces latency and improves transfer speeds.

A: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking.html C: https://aws.amazon.com/ec2/instance-types/#Instance_Features Select EC2 instances support cluster networking when launched into a common cluster placement group. A cluster placement group provides low-latency networking between all instances in the cluster. The bandwidth an EC2 instance can utilize depends on the instance type and its networking performance specification.

AC Use of Placement Groups: Utilize EC2 Placement Groups to ensure that instances are physically located close to each other within the same Availability Zone. This reduces the latency between instances by minimizing the distance data needs to travel. Selection of EC2 Instance Types: Choose EC2 instance types optimized for low-latency networking, such as instances with enhanced networking capabilities like Elastic Network Adapter (ENA) or instances that support Amazon EC2 Nitro System. These instances provide high throughput and low latency networking performance.

option C & E. Option A is not viable as ..EC2 provides enhanced networking capabilities using single root I/O virtualization (SR-IOV) only on supported instance types.

Enhanced networking is available on most modern instance families, such as C5, M5, R5, P3, G4, and others. Always check the AWS documentation https://aws.amazon.com/ec2/instance-types/ for the latest list of supported instance types:
