Which of the following statements about the commands shown in the figure is true?

Comprehensive and Detailed Explanation:

The history-command max-size command in Huawei VRP (Versatile Routing Platform) is used to set the maximum number of previously used commands that can be saved in the command history buffer.

By default, Huawei devices store 5 previously-used commands in the buffer.

The command history-command max-size 20 increases the buffer size to 20 commands.

This does not limit the buffer to 20 bytes; instead, it allows 20 entire commands to be stored.

The correct statement that matches this behavior is:

"The history-command max-size 20 command sets the maximum of previously-used commands that can be saved in the buffer to 20."
