You administer Windows 8.1 Enterprise client computers in your company network.
You change settings on a reference computer by using the Windows Firewall with Advanced
Security tool. You want to apply the same settings to other computers.
You need to save the Windows Firewall with Advanced Security configuration settings from
the reference computer. You also need to be able to import the configuration settings into a
Group Policy object later.
What should you do?
A.
Run the netsh advfirewall export c:\settings.xml command.
B.
Open Local Group Policy Editor, select the Windows Firewall with Advanced Security
node, and then select the Export Policy action.
C.
Open Local Group Policy Editor, select the Security Settings node, and then select the
Export List action.
D.
From Control Panel, open Windows Firewall, click Advanced Settings, and then select the
Export Policy action.
Wrong answer, the file would be in .wfw format.

From your link:
[Path]FileName
Required. Specifies, by name, the file where the Windows Firewall with Advanced Security configuration will be written. If the path, file name, or both contain spaces, quotation marks must be used. If you do not specify Path then the command places the file in your current folder. The recommended file name extension is .wfw.
.wfw seems to be recommended, not compulsory. That would make A a valid option.
Answer is B
(D)
Go into advanced firewall settings in the control panel of the reference computer. Export an xxx.wfw file. You can import this file into a GPO.
