NEW QUESTION # 28
Which smbclient invocation displays a list of the available SMB shares on the remote Samba server FileSrv1?
- A. smbcontrol -L FileSrv1
- B. smbclient -L FileSrv1
- C. smbstatus -S FileSrv1
- D. smbmount -L FileSrv1
- E. smbshares --server 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 # 29
Which parameter within a share definition in the Samba configuration makes Samba only show files and directories on a file share which a user can access?
- A. display mode = 100
- B. valid files = read,write
- C. hide unreadable = yes
- D. browse mask = 000
- E. browseable = readable
Answer: C
Explanation:
hide unreadable: This smb.conf option ensures that only files and directories that the user has permissions to access are visible in the file share.
Functionality: When set to yes, files and directories that the user cannot read (due to permissions) will be hidden from their view.
Security and Usability: This helps in enhancing both security and usability by preventing users from seeing files they cannot access, reducing clutter and potential confusion.
Example Configuration:
[example_share] hide unreadable = yes

NEW QUESTION # 33
Which of the following smb.conf options turns a regular file share into a DFS share?
- A. addfs support = yes
- B. proxy share = yes
- C. msdfs root = yes
- D. follow symlinks = yes
- E. dfs forward = yes
Answer: C
Explanation:
DFS (Distributed File System): This allows for the organization of shared files on multiple servers in a distributed file system.
msdfs root = yes: This option in the Samba configuration file (smb.conf) enables a share to be a DFS root. This means the share can provide access to multiple other shares possibly located on different servers, creating a single point of access.
Functionality: When enabled, users accessing this DFS root can be redirected transparently to the actual location of the shared files, which might be spread across different servers.
Setup: To configure a DFS root, add msdfs root = yes to the specific share definition in smb.conf.

NEW QUESTION # 34
The [homes] section of smb.conf contains the parameter browseable = no. What are the resulting consequences? (Choose two.)
- A. When browsing the Samba server, there is no visible share called homes.
- B. When browsing the Samba server, users can open the homes share but they cannot see the content of their home directories.
- C. When browsing the Samba server, there is no visible share named after the current user.
- D. If the Samba server is part of an Active Director/ Domain, only users in the qroup Se3rowsingUsers can browse the homes share.
- E. The homes share can be directly accessed by specifically opening this share by its UNC path.
Answer: C,E
Explanation:
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.

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: D
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.

Which of the following commands terminates all running instances of the Samba daemon handling for SMB shares?
- A. smbcontrol smbd shutdown
- B. smbcontrol nmbd shutdown
- C. smbcontrol samba shutdown
- D. smbcontrol shutdown
- E. smbcontrol cifs stop
Answer: A
Explanation:
Samba is a suite of programs that allows SMB/CIFS clients to interact with file and print services on a Linux/UNIX server.
smbd is the Samba daemon responsible for handling SMB/CIFS requests.
The smbcontrol utility is used to send messages to running Samba daemons.
The correct way to terminate all running instances of the Samba daemon handling SMB shares is to send a shutdown message to smbd using the command smbcontrol smbd shutdown.
This command ensures that only the smbd processes, which are responsible for handling SMB shares, are terminated without affecting other Samba components like nmbd (NetBIOS name server daemon).
