AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 275

Which of the following statements does not describe Jumbo Frames in an AWS VPC environment?

Answer options

• A. For instances that are collocated inside a placement group, jumbo frames help to achieve the maximum network throughput possible
• B. Jumbo Frames are not supported for traffic that exits the Virtual Private Gateway
• C. Jumbo Frames are not supported for traffic that exits the Internet Gateway
• D. T2.micro instances do not support Jumbo Frames

Correct answer: D

Explanation

While T2.micro instances have limited network performance, they still support Jumbo Frames (9001 MTU) for traffic within the VPC, making option D an incorrect statement and therefore the correct answer. Conversely, jumbo frames are indeed used within placement groups to maximize network throughput, but they are automatically packet-fragmented to a standard 1500 MTU when traversing an Internet Gateway or a Virtual Private Gateway.
