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
正解：D
解説：
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.

質問 # 23
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. 0555
- D. 0750
- E. 0755
正解：C
解説：
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.

- D. samba-tool join samba.private member
- E. samba-tool domain join samba.private member
正解：E
解説：
Understanding Samba Domain Join: Joining a Samba server to a domain allows it to authenticate and provide resources to users of that domain.
Command Breakdown: The correct command format for joining a Samba server as a member of a domain involves the "domain join" action followed by the domain name and the role. In this case, "samba.private" is the domain name, and "member" specifies the role.
Command
samba-tool domain join samba.private member:
samba-tool: A command-line utility for managing Samba.
domain join: Specifies the action of joining a domain.
samba.private: The domain to join.
member: The role within the domain.

質問 # 25
In order to generate an individual log file for each of the machines connecting to a Samba server, which of the following statements must be used in the Samba configuration file?
- A. log file = /var/log/samba/log.%c
- B. log file = /var/log/samba/log.%M
- C. log file = /var/log/samba/log.%m
- D. log file = /var/log/samba/log.%r
- E. log file = /var/log/samba/log.%I
正解：C
解説：
Individual Log Files:
A . log file = /var/log/samba/log.%m: To generate an individual log file for each machine connecting to a Samba server, the %m variable is used in the log file path. This variable represents the machine name of the connecting client. Thus, the configuration line log file = /var/log/samba/log.%m creates a unique log file for each client machine.

質問 # 27
Which of the following statements is true about raw printing with Samba?
- A. Printing jobs are rendered on the client and passed on to the printer by Samba.
- B. Samba converts printer-specific jobs to raw data to make them printable on an arbitrary printer.
- C. Print jobs are submitted as vector files, including font files, which are rendered and printed by Samba.
- D. Printing jobs are always submitted to Samba in raw postscript.
- E. 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.
正解：A
解説：
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.

正解：C、D
解説：
The samba-tool group add command is used to add a new group to the Samba Active Directory. This command has several parameters to customize the group creation process. Two of the available parameters are --sid and --group-type.
--sid:
The --sid parameter allows you to specify a Security Identifier (SID) for the new group.

質問 # 30
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. 0
- B. 066
- C. 1
- D. 027
- E. 2
正解：C
解説：
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.
Reference:
Samba smb.conf man page - create mask
