A. B. C. D.

Answer - A and D.

This is given in the AWS documentation.

All Amazon EC2 instance types support 1500 MTU, and many current instance sizes support 9001 MTU, or jumbo frames.

For more information on Network MTU, please visit the below link:

http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/network_mtu.html

The MTU (Maximum Transmission Unit) is the maximum size of a packet that can be transmitted over a network link. In AWS, instances support two types of MTUs:

  1. Standard MTU: This has an MTU size of 1500 bytes, which is the default for most networks.

  2. jumbo frames MTU: This has an MTU size of up to 9001 bytes. Jumbo frames can reduce network overhead and increase throughput, but they may not be supported by all network devices.

Therefore, the correct answers are A. 1500 and D. 9001.
