D522 Task 2 Objective B Confusion

I'm confused on what I'm supposed to be doing for this objective.

The instructions say:

B.  Before making any changes to the devices on your network, write a Python script to create a backup directory of the DNS server device configuration files in the attached "network_devices" CSV file by copying the device configuration and creating a subdirectory for both DNS servers in the network.

However, the reference guide they recently released with somewhat less horrible wording says:

"Backup the configurations of these devices to the files by writing the response from your commands to each of these files for each of the devices. The folders and files will be stored on your local lab machine."

Given that wording, it seems I'm supposed to obtain the config for each DNS server from a command, then write it to a file? But I'm not sure what command that would be, or where the configs for each DNS server are located.
