ANS-C01: Improve Network Performance between On-Premises and Security Appliance on EC2 using Enhanced Networking and Placement Groups

Learn how a network engineer can improve networking speeds between an on-premises data center and a security appliance running on an EC2 instance by enabling enhanced networking and placement groups.

Question

A company’s security guidelines state that all outbound traffic from a VPC to the company’s on-premises data center must pass through a security appliance. The security appliance runs on an Amazon EC2 instance. A network engineer needs to improve the network performance between the on-premises data center and the security appliance.

Which actions should the network engineer take to meet these requirements? (Choose two.)

A. Use an EC2 instance that supports enhanced networking.
B. Send outbound traffic through a transit gateway.
C. Increase the EC2 instance size.
D. Place the EC2 instance in a placement group within the VPC.
E. Attach multiple elastic network interfaces to the EC2 instance.

Answer

A. Use an EC2 instance that supports enhanced networking.
D. Place the EC2 instance in a placement group within the VPC.

Explanation

Enhanced networking provides significantly higher performance networking capabilities for EC2 instances by bypassing the virtual switch and allowing direct access to the physical network hardware. This will improve network performance between the on-premises data center and the security appliance running on the EC2 instance.

Placement groups ensure adequate networking performance by launching EC2 instances in groups that are physically close to each other. Placing the security appliance EC2 instance in a placement group isolates it from interference caused by other instances on the underlying hardware, improving network performance.

While increasing instance size (C) or attaching multiple ENIs (E) may help processing power, they do not directly improve networking which is the focus here. And using a transit gateway (B) is not needed as all traffic must pass through the on-premises-hosted security appliance.
