NEW QUESTION # 17
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. 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.
- D. Printing jobs are always submitted to Samba in raw postscript.
- E. Print jobs are submitted as vector files, including font files, which are rendered and printed by Samba.
Answer: A
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.

NEW QUESTION # 21
A Samba 4 server provides DNS information regarding an Active Directory Domain. All other DNS information is provided by an additional DNS server. Which of the following solutions ensures that the clients of the Samba server can look up all DNS records including those from the domain?
- A. The search domain of all clients is set to the Active Directory domain name. All clients query only the additional DNS server and not a domain controller.
- B. All clients are configured to send DNS queries to the additional DNS server only. The Samba server's smb.conf contains the option wins dns proxy = yes to provide all domain-related naming information via the NetBIOS name service independently from DNS.
- C. The additional DNS server is configured in the option dns forwarder in smb.conf. All clients query the Samba server for any DNS information.
- D. Both the Samba server and the additional DNS server are configured on the clients. This ensures that the Samba server is listed first in each client's resolv.conf.
- E. The additional DNS server is configured in the file /etc/resolv.conf on the Samba server and the option dns forwarder = yes is set in smb.conf.
Answer: C
Explanation:
dns forwarder: This smb.conf option specifies the DNS server to which queries should be forwarded if they cannot be resolved locally by the Samba server.
Configuration:
Add dns forwarder = <additional_DNS_server_IP> to smb.conf on the Samba server.
Ensure all clients are configured to query the Samba server for DNS information.
Process:
Clients send all DNS queries to the Samba server.
If the Samba server cannot resolve a query locally, it forwards the request to the additional DNS server.
Benefit: This ensures that all DNS records, including those from the Active Directory domain and other DNS information, can be resolved by the clients.

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: E
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 smb.conf options turns a regular file share into a DFS share?
- A. proxy share = yes
- B. msdfs root = yes
- C. dfs forward = yes
- D. addfs support = yes
- E. follow symlinks = yes
Answer: B
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.

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.%I
- D. log file = /var/log/samba/log.%m
- E. log file = /var/log/samba/log.%r
Answer: D
Explanation:
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.

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