NEW QUESTION # 30
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. Printing jobs are always submitted to Samba in raw postscript.
- 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. 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 # 32
Which of the following lines is missing in the given [printers] share definition?
- A. print admin = Administrator, root, @lpadmin
- B. load printers = yes
- C. printable = yes
- D. printcap name = cups
- E. print script = /usr/bin/lp -d %P %s
Answer: C
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.

NEW QUESTION # 35
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 additional DNS server is configured in the option dns forwarder in smb.conf. All clients query the Samba server for any DNS information.
- B. 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.
- C. 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.
- D. 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.
- E. 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.
Answer: A
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.

NEW QUESTION # 37
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. follow symlinks = yes
- D. msdfs root = yes
- E. dfs forward = yes
Answer: D
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.
Reference:
Samba DFS Configuration

Which of the following statements about automount in a FreeIPA domain are true? (Choose two.)
- A. In a FreeIPA domain, mount points for automount are always directories.
- B. The command ipa automount up mounts all file systems handled by automount on a FreeIPA client.
- C. In a FreeIPA domain, automount can only mount NFS shares from FreeIPA servers.
- D. The base configuration file for automount is /etc/auto.master.
- E. In a FreeIPA domain, automount requires SSSD to be installed on each client.
Answer: D,E
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:
