NEW QUESTION # 23
What are benefits of registry based Samba configuration compared to file based configuration? (Choose three.)
- A. Registry based configuration supports advanced options which do not exist in smb.conf.
- B. Specific attributes of LDAP objects in Active Directory can be overwritten in the configuration registry.
- C. Server processes require less time to start because they do not have to parse the configuration file.
- D. Configuration changes become effective immediately without a daemon reload.
- E. The registry can be edited remotely without logging into the server.
Answer: C,D,E
Explanation:
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.

NEW QUESTION # 24
The configuration of a Samba share contains the following line:
force directory mode = 0555
If a client creates a new directory with the permissions 0750, which permissions will the resulting directory have in the Samba server's file system?
- A. 0750
- B. 0777
- C. 0755
- D. 0750
- E. 0555
Answer: E
Explanation:
force directory mode = 0555: This setting in Samba forces the permissions of any newly created directories to be 0555 regardless of what the client requests.
Client Request: If a client creates a directory with permissions 0750, Samba will override this and set the directory's permissions to 0555.
Permissions Breakdown:
0: No permissions for owner.
5: Read and execute permissions for the group.
5: Read and execute permissions for others.
Enforcement: Samba applies this mode strictly to ensure consistency and security as defined by the administrator.

Which of the following lines is missing in the given [printers] share definition?
- A. printable = yes
- B. print admin = Administrator, root, @lpadmin
- C. load printers = yes
- D. print script = /usr/bin/lp -d %P %s
- E. printcap name = cups
Answer: A
Explanation:
In the context of a Samba configuration for printer shares, the [printers] section usually requires the printable = yes directive to indicate that the share is meant for printing. Without this directive, Samba would not treat the share as a printer share, even if other settings like path are configured properly.
The given snippet is:

When using rsync to synchronize the SYSVOL share's contents between multiple Samba servers, which of the following precautions should be taken? (Choose three.)
- A. Overwrite the permissions of all files in the SYSVOL directory to be readable by root only after each sync.
- B. Make sure that the SYSVOL share is active on only one domain controller.
- C. Make sure to make all changes to GPOs on the domain controller which is the replication source.
- D. Make the SYSVOL share read only on all domain controllers but the one used as synchronization source.
- E. Synchronize from the domain controller which is the PDC emulator to the other domain controllers.
Answer: C,D,E
Explanation:
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.

NEW QUESTION # 35
Which of the following statements is true about raw printing with Samba?
- A. Printing jobs are always submitted to Samba in raw postscript.
- B. Any printed file, e.g. an office document, is submitted to the printer without any further processing in exactly the same bit sequence as it is stored on disk.
- C. Samba converts printer-specific jobs to raw data to make them printable on an arbitrary printer.
- D. Printing jobs are rendered on the client and passed on to the printer by Samba.
- E. Print jobs are submitted as vector files, including font files, which are rendered and printed by Samba.
Answer: D
Explanation:
Client-Side Rendering: In Samba, raw printing means that the client machine renders the print job, which includes converting it to a printer-ready format.
Transmission to Printer: This rendered print job is then sent to the Samba server without further processing or alteration. Samba acts merely as a pass-through, sending the job directly to the printer.
Advantages: This method offloads the rendering process from the server to the client, which can be beneficial in environments with diverse printer types and models, reducing the processing load on the server.
Conclusion: Thus, the correct answer is that printing jobs are rendered on the client and passed on to the printer by Samba.

- B. The base configuration file for automount is /etc/auto.master.
- C. In a FreeIPA domain, mount points for automount are always directories.
- D. In a FreeIPA domain, automount can only mount NFS shares from FreeIPA servers.
- E. The command ipa automount up mounts all file systems handled by automount on a FreeIPA client.
Answer: A,B
Explanation:
Automounting in a FreeIPA domain involves several key aspects:
Base Configuration File (/etc/auto.master): The auto.master file is the main configuration file for the automounter. It contains the master map which defines mount points and their corresponding maps. This file is crucial for setting up automount points.
Example entry in /etc/auto.master:
plaintext
Copy code
/home /etc/auto.home
SSSD Requirement: In a FreeIPA domain, automount requires the System Security Services Daemon (SSSD) to be installed and configured on each client. SSSD is used to retrieve automount maps from the FreeIPA server, enabling the automount feature to function correctly.
Example configuration in /etc/sssd/sssd.conf:
[sssd] services = nss, pam, autofs config_file_version = 2 domains = example.com [domain/example.com] autofs_provider = ipa ipa_server = _srv_ Reference:
