The files in the \winnt\repair directory can be automatically scheduled for updating using the rdisk /s- command. Choose the statement that is TRUE.

A.
When your Emergency Repair Disk (ERD) is not up-to-date, an up-to-date \winnt\repair directory cannot be used to repair a Windows server installation.

B.
The /s parameter in the rdisk /s- command instructs the repair disk utility to only repair directory data, and not the ERD.

C.
The minus sign in the rdisk /s- command stops the repair disk utility from requesting a floppy disk to generate a new ERD when the winnt\repair directory is being updated.

D.
All of the above.

Explanation:
The minus sign in the rdisk /s- command stops the repair disk utility from requesting a floppy disk to generate a new ERD when the winnt\repair directory is being updated.
Bear in mind though that using the \winnt\repair directory to repair a Windows server installation will only work when the server happens to fail in the networked environment.

B: The /s parameter of the rdisk /s- command tells the repair disk utility to repair directory data and update the ERD.
