AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 67

A computing team is evaluating whether to place a high performance computing (HPC) application in AWS. The team is concerned about application performance and wants to know what options are available to increase networking performance.
Which of the following changes would increase performance for this application? (Choose two.)

Answer options

• A. Place the application across many smaller instances to achieve higher total throughput.
• B. Increase the MTU of the VPC to 9001.
• C. Enable an MTU of 9001 in the application's operating system.
• D. Enable enhanced networking on the instances.
• E. Deploy the application in two Availability Zones and insert them in one placement group.

Correct answer: C, D

Explanation

The correct answers are C and D because enabling an MTU of 9001 in the operating system and enabling enhanced networking on the instances both directly enhance the network performance of the application. Options A and E do not specifically address networking performance enhancements, while option B only increases the MTU at the VPC level, which is not sufficient without the corresponding settings in the operating system.
