Win 98 Registry backup files

the_alpha_geekguy

My Brook's A+ text says:

"Windows 98 Registry are stored in \Windows\Sysbckup directory in the form of cabinet (.cab) files-not .da0 files" as they are in Windows 95.

Further down the text says that the files that the above cab files contain the following files:

"User.dat, System.dat, Win.ini, System.ini" and are stored in a "RB0XX.cab" file

I had always assumed that Win9x registry backups were all stored as .da0 files.

The thing is that the Preplogic Test that came with the book asks:

"On one occasion you notice that a Windows 98 user has deleted the registry, but you notice that their backup registry files are intact. Which files will you use to restore the registry?

The two potentially correct options out of the list given are:
1.) user.da0; system.da0
2.) user.dat; system.dat

Based on the info given in the book, i picked 2.) because supposedly .da0 files are not used with Win98 but the correct answer is 1.).

Anyone know what's going on here?
