The statements that are true regarding a daemon are:

A daemon will wait for some event to occur to trigger action on the part of the daemon.

A daemon process is launched by the system.

A daemon process is not associated with a terminal or a graphical environment.

A daemon is a background process that performs a specific service or task without user interaction. It usually starts at system boot and runs until the system shuts down. It does not have a controlling terminal or a graphical interface, and it often runs as root or a dedicated user. A daemon responds to events such as network requests, signals, timers, etc. Reference: https://documentation.suse.com/sles/15-SP3/html/SLES-all/sec-daemons.html

Answer : B

It is false that it is not possible to open more than one file in Vim without running a second instance. Vim supports multiple buffers, windows, and tabs that allow you to work with multiple files within one Vim session. You can use various commands and options to open, switch, split, close, and manipulate files in different ways.

Answer : B

The command that you would run to create an updated initial file system, if your server hardware requires additional drivers to be available for the kernel at boot up, is mkinitrd. This command will create or update the initrd file in /boot based on the current kernel and configuration files. The initrd file is an initial ramdisk image that contains the necessary drivers and tools to mount the root file system and start the boot process.

Answer : B

If you are setting up a SLES 15 server that will require very large data volumes and journaling capabilities, the best choice for your data volumes is XFS. XFS is a high-performance and scalable file system that supports large files and file systems, online defragmentation and resizing, metadata checksums, and other features. XFS also provides journaling capabilities that ensure data consistency and integrity in case of system crashes or power failures. XFS is the default file system for data partitions in SLES 15.

Answer : C

The command that will take a foreground process and suspend it, and then place it in the background as a stopped job is Ctrl+Z. This keyboard shortcut will send a SIGTSTP signal to the foreground process group, which will stop its execution and return control to the shell. The shell will then display the job number and status of the stopped process. To resume the process in the background, you can use the bg command with the job number or % sign.

Answer : F, G

The valid device types are character and block devices. Character devices are devices that transfer data byte by byte, such as keyboards, mice, terminals, etc. Block devices are devices that transfer data in fixed-size blocks, such as disks, CD-ROMs, etc. Pipe, null, redirect, udev, and network are not device types but rather concepts or components related to devices or device management.

Answer : D

The command that is used to ensure an ext3 file system is checked every 50 times it is mounted is tune2fs. The tune2fs command can be used to adjust various parameters of an ext2, ext3, or ext4 file system. The -c option can be used to set the maximum number of mounts between two file system checks. For example, tune2fs -c 50 /dev/sda1 will set the check interval to 50 mounts for /dev/sda1. Reference: https://documentation.suse.com/sles/15-SP3/html/SLES-all/sec-tune2fs.html
