NEW QUESTION # 24
Which of the following names identify services within a SSSD configuration file? (Choose three.)

• A. nss
• B. sudo
• C. ssh
• D. smb
• E. kerberos

Answer: A,B,E

Explanation:
In the SSSD (System Security Services Daemon) configuration file, various services can be defined to handle different types of access and authentication. The services listed in the SSSD configuration file under the [sssd] section can include:
kerberos: This service allows SSSD to handle Kerberos authentication.
nss (Name Service Switch): This service provides name resolution and manages user and group information.
sudo: This service enables SSSD to provide sudo rules based on the identity provider.
These services are specified in the services attribute of the [sssd] section of the sssd.conf file.
Example:
[sssd] services = nss, pam, sudo domains = LDAP [nss] filter_users = root filter_groups = root [sudo] sudo_provider = ldap Reference:

NEW QUESTION # 25
The [homes] section of smb.conf contains the parameter browseable = no. What are the resulting consequences? (Choose two.)

• A. When browsing the Samba server, users can open the homes share but they cannot see the content of their home directories.
• B. The homes share can be directly accessed by specifically opening this share by its UNC path.
• C. When browsing the Samba server, there is no visible share called homes.
• D. When browsing the Samba server, there is no visible share named after the current user.
• E. If the Samba server is part of an Active Director/ Domain, only users in the qroup Se3rowsingUsers can browse the homes share.

Answer: B,D

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.

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.

NEW QUESTION # 27
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.

Which command line option instructs smbclient to authenticate using an existing Kerberos token? (Specify ONLY the option name without any values or parameters.)

Answer:

Explanation:
k
Explanation:
The smbclient command is used to access shared resources on a server running the SMB/CIFS protocol. To authenticate using an existing Kerberos token, the -k option is used. This instructs smbclient to use Kerberos for authentication, assuming that the user already has a valid Kerberos ticket (usually obtained via the kinit command).
Example:
smbclient //server/share -k

NEW QUESTION # 32
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.

NEW QUESTION # 33
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.

Explanation:
Purpose of the Command: testparm is used to check the Samba configuration file (smb.conf) for syntax errors.
Command
Running testparm will read the smb.conf file, parse it, and display any syntax errors or warnings. This helps ensure that the configuration is valid before restarting the Samba service.
Usage Example:
Simply execute testparm in the terminal, and it will automatically check the default configuration file.
