NEW QUESTION # 24
In case the following parameters are set in a Samba file share configuration:
create mask = 711
force create mode = 750
What are the effective permissions of a file created with the permissions 777?
- A. 066
- B. 027
- C. 0
- D. 1
- E. 2
Answer: D
Explanation:
The effective permissions of a file created with the permissions 777 can be calculated considering the create mask and force create mode.
create mask = 711 implies that the permission bits are ANDed with 0711, i.e., only the owner can read, write, and execute.
force create mode = 750 implies that certain permission bits are always set, specifically 0750, i.e., read, write, and execute for the owner, and read and execute for the group.
The create mask reduces the permissions to 0711, and then force create mode adds the 0750 mask to the result.
Original permission: 777 AND with create mask (711): 711 OR with force create mode (750): 751 Thus, the effective permission is 751.

Which smbclient invocation displays a list of the available SMB shares on the remote Samba server FileSrv1?
- A. smbshares --server FileSrv1
- B. smbclient -L FileSrv1
- C. smbmount -L FileSrv1
- D. smbstatus -S FileSrv1
- E. smbcontrol -L FileSrv1
Answer: B
Explanation:
The smbclient command is used to access shared resources on a network that uses the SMB (Server Message Block) protocol. To list the available SMB shares on a remote Samba server, the correct invocation is smbclient -L <server_name>. Here, -L stands for "list" and <server_name> is the name of the Samba server. Therefore, smbclient -L FileSrv1 will list all the available SMB shares on the server named FileSrv1.

NEW QUESTION # 26
Which of the following statements is true about raw printing with Samba?
- A. Print jobs are submitted as vector files, including font files, which are rendered and printed by Samba.
- B. Printing jobs are rendered on the client and passed on to the printer by Samba.
- C. Samba converts printer-specific jobs to raw data to make them printable on an arbitrary printer.
- D. 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.
- E. Printing jobs are always submitted to Samba in raw postscript.
Answer: B
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.

Which of the following lines is missing in the given [printers] share definition?
- A. printable = yes
- B. load printers = yes
- C. printcap name = cups
- D. print admin = Administrator, root, @lpadmin
- E. print script = /usr/bin/lp -d %P %s
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:
The line printable = yes is missing and is essential for defining a printer share.

Which of the following TCP ports is used to provide the SMB protocol without NetBIOS?
- A. 0
- B. 1
- C. 2
- D. 3
- E. 4
Answer: B
Explanation:
The SMB protocol (Server Message Block) is used for providing shared access to files and printers.
Historically, SMB ran on top of NetBIOS over TCP/IP using port 139.
SMB can also run directly over TCP/IP without the NetBIOS layer, which uses port 445.
Therefore, TCP port 445 is used to provide the SMB protocol without NetBIOS.

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. Make sure that the SYSVOL share is active on only one domain controller.
- B. Synchronize from the domain controller which is the PDC emulator to the other domain controllers.
- 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. Overwrite the permissions of all files in the SYSVOL directory to be readable by root only after each sync.
Answer: B,C,D
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.

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. 0755
- C. 0750
- D. 0555
- E. 0777
Answer: D
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.
