Bsamba-backup

Cldbbackup

Dsmbbackup

Eldbsync

Answer : C

Consistent Copy of LDB Files:

Question 6

The [homes] section of smb.conf contains the parameter browseable = no. What are the resulting consequences? (Choose two.)

AWhen browsing the Samba server, there is no visible share named after the current user.

BIf the Samba server is part of an Active Director/ Domain, only users in the qroup Se3rowsingUsers can browse the homes share.

CWhen browsing the Samba server, users can open the homes share but they cannot see the content of their home directories.

DThe homes share can be directly accessed by specifically opening this share by its UNC path.

EWhen browsing the Samba server, there is no visible share called homes.

Answer : A, D

When browseable = no is set in the [homes] section of smb.conf, it prevents the share from appearing in the list of available shares when users browse the server. However, users can still access their home directories if they specify the correct UNC path directly.

A . When browsing the Samba server, there is no visible share named after the current user.

The share will not appear in the list of shares visible to the user during browsing.

D . The homes share can be directly accessed by specifically opening this share by its UNC path.

Users can still access the share by directly typing the path in the form \\servername\username.

Question 7

When using rsync to synchronize the SYSVOL share's contents between multiple Samba servers, which of the following precautions should be taken? (Choose three.)

ASynchronize from the domain controller which is the PDC emulator to the other domain controllers.

BOverwrite the permissions of all files in the SYSVOL directory to be readable by root only after each sync.

CMake the SYSVOL share read only on all domain controllers but the one used as synchronization source.

DMake sure that the SYSVOL share is active on only one domain controller.

EMake sure to make all changes to GPOs on the domain controller which is the replication source.

Answer : A, C, E

When using rsync to synchronize the SYSVOL share's contents between multiple Samba servers, it's essential to ensure data consistency and avoid conflicts. The following precautions should be taken:

A . Synchronize from the domain controller which is the PDC emulator to the other domain controllers.

The PDC emulator is typically the authoritative source for certain domain-wide operations, making it the best source for SYSVOL synchronization.

C . Make the SYSVOL share read only on all domain controllers but the one used as synchronization source.

This prevents changes on other domain controllers that could cause inconsistencies.

E . Make sure to make all changes to GPOs on the domain controller which is the replication source.

Ensuring that all Group Policy Objects (GPOs) changes are made on the source controller prevents conflicts and ensures that all controllers have the latest configuration.
