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?
Answer : E
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 = 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.

Question 3
In a Samba configuration file, which of the following variables represents the domain of the current user?
Answer : A
In a Samba configuration file, variables can be used to represent dynamic values.
The %D variable represents the domain of the current user.
This variable can be used in various configuration directives to customize the behavior of Samba services based on the user's domain.
Which of the following statements about automount in a FreeIPA domain are true? (Choose two.)
Answer : C, D
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.
What service name must be added to a database entry in /etc/nsswitch.conf to include SSSD as a source of information? (Specify ONLY the service name without any parameters.)
Answer : A
Adding SSSD to /etc/nsswitch.conf:
To include SSSD (System Security Services Daemon) as a source of information in the /etc/nsswitch.conf file, the service name sss must be added. This is specified without any parameters. The sss service allows the system to retrieve information from various sources, such as LDAP, Kerberos, and others, as configured in SSSD.
