Remote Editing:
A . The registry can be edited remotely without logging into the server: One of the benefits of registry-based Samba configuration is that the registry can be edited remotely. This means administrators can make changes without needing to log into the server directly, facilitating easier and more flexible management.
Improved Startup Time:
C . Server processes require less time to start because they do not have to parse the configuration file: Registry-based configurations can reduce startup time because the Samba server processes do not need to parse a potentially complex smb.conf file. Instead, they access the configuration directly from the registry, which can be faster.
Immediate Effect of Configuration Changes:
D . Configuration changes become effective immediately without a daemon reload: Changes made in the registry are applied immediately and do not require a daemon reload. This can be very advantageous for administrators who need to make quick adjustments without interrupting the service.
