Question

You are a Solutions Architect in an intelligence agency that is currently hosting a learning and training portal in AWS. Your manager instructed you to launch a large EC2 instance with an attached EBS Volume and enable Enhanced Networking. What are the valid case scenarios in using Enhanced Networking? (Choose 2)

Options are:
a. When you need a higher packet per second (PPS) performance
b. When you need a low packet-per-second performance
c. When you need high latency networking
d. When you need a consistently lower inter-instance latencies
e. When you need a dedicated connection to your on-premises data center

Answer 1

Enhanced Networking in AWS EC2 is suitable for scenarios requiring higher packet per second performance and consistently lower inter-instance latencies, supported by network technologies like ENA or VF.

Step-by-step explanation:

Enhanced Networking on AWS provides higher performance for Amazon EC2 instances, which can be particularly beneficial in specific scenarios such as when higher packet per second (PPS) performance is required or when you need consistently lower inter-instance latencies. These features are critical for applications that are sensitive to network performance. Enhanced Networking is enabled by using a network virtualization technology called the Elastic Network Adapter (ENA) or Intel 82599 Virtual Function (VF) interface for supported instance types.

Option (a), enabling Enhanced Networking for higher packet per second performance, is valid because Enhanced Networking allows instances to achieve significantly higher PPS with lower CPU utilization. Option (d), needing consistently lower inter-instance latencies, is also valid since Enhanced Networking minimizes jitter (variability in packet latency) which is important in a learning and training portal where consistency and low latency communication between instances can be critical for delivering real-time content.
