Which of the following commands open NFSv4 ACLs in an editor? (Choose two.)
To open NFSv4 ACLs in an editor, the following commands can be used:
nfs4_setfacl -e: This command is used to set NFSv4 ACLs, and the -e option opens the ACLs in an editor for modification. The command usage is:
This opens the ACL editor where the user can modify the ACLs for the specified file.
nfs4_editfacl: This command is a more intuitive way to edit NFSv4 ACLs directly in an editor. It provides a user-friendly interface for managing ACLs.

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?
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 statements about automount in a FreeIPA domain are true? (Choose two.)
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_

In case the following parameters are set in a Samba file share configuration:
create mask = 711
force create mode = 750
What are the effective permissions of a file created with the permissions 777?
The effective permissions of a file created with the permissions 777 can be calculated considering the create mask and force create mode.
create mask = 711 implies that the permission bits are ANDed with 0711, i.e., only the owner can read, write, and execute.
force create mode = 750 implies that certain permission bits are always set, specifically 0750, i.e., read, write, and execute for the owner, and read and execute for the group.
The create mask reduces the permissions to 0711, and then force create mode adds the 0750 mask to the result.
Original permission: 777 AND with create mask (711): 711 OR with force create mode (750): 751
Thus, the effective permission is 751.
