A Linux administrator found many containers in an exited state. Which of the following commands will allow the administrator to clean up the containers in an exited state?
Explanation:
The command docker rm $(docker ps -aq) will allow the administrator to clean up the containers in an exited state. The docker command is a tool for managing Docker containers on Linux systems.
Docker containers are isolated and lightweight environments that can run applications and services without affecting the host system. Docker uses images to create containers, which are files that contain the code, libraries, dependencies, and configuration of the applications and services.
The rm option removes one or more containers. The $(docker ps -aq) is a command substitution that executes the command inside the parentheses and replaces it with the output. The docker ps -aq command lists all the containers, including the ones in an exited state, and shows only their IDs.
The docker rm $(docker ps -aq) command will remove all the containers, including the ones in an exited state, by passing their IDs to the rm option. This will allow the administrator to clean up the containers in an exited state. This is the correct command to use to accomplish the task. The other options are incorrect because they either do not exist (docker rm --all or docker rm --state exited) or do not remove the containers (docker images prune *).

A systems administrator is enabling LUKS on a USB storage device with an ext4 filesystem format. The administrator runs dmesg and notices the following output:
Given this scenario, which of the following should the administrator perform to meet these requirements? (Select three).
Explanation:
To enable LUKS on a USB storage device with an ext4 filesystem format, the administrator needs to perform the following steps:
Unmount the device if it is mounted usingumount /dev/sdc(D)
Create a partition table on the device usingfdisk /dev/sdc(E)
Format the partition with LUKS encryption usingcryptsetup luksFormat /dev/sdc1(H)
Open the encrypted partition usingcryptsetup luksOpen /dev/sdc1 LUKS0001
Create an ext4 filesystem on the encrypted partition usingmkfs.ext4 /dev/mapper/LUKS0001
Mount the encrypted partition usingmount /dev/mapper/LUKS0001 /mntReference:

A Linux administrator needs to harden a system and guarantee that the Postfix service will not run, even after a restart or system upgrade. Which of the following commands allows the administrator to fulfill the requirement?
A Linux systems administrator is updating code. After completing the update, the administrator wants to publish the updated code without including the configuration files. Which of the following should the administrator use to accomplish this task?
A Linux system fails to start and delivers the following error message:
Which of the following commands can be used to address this issue?
Explanation:
The command fsck.ext4 /dev/sda1 can be used to address the issue. The issue is caused by a corrupted filesystem on the /dev/sda1 partition. The error message shows that the filesystem type is ext4 and the superblock is invalid. The command fsck.ext4 is a tool for checking and repairing ext4 filesystems. The command will scan the partition for errors and attempt to fix them. This command can resolve the issue and allow the system to start. The other options are incorrect because they either do not fix the filesystem (partprobe or fdisk) or destroy the data on the partition (mkfs.ext4).

A systems administrator needs to check if the service systemd-resolved.service is running without any errors. Which of the following commands will show this information?
Explanation:
The command systemctl status systemd-resolved.service will show the information about the service systemd-resolved.service. The systemctl command is a tool for managing system services and units. The status option displays the current status of a unit, such as active, inactive, or failed. The output also shows the unit description, loaded configuration, process ID, memory usage, and recent log messages. This command will show if the service systemd-resolved.service is running without any errors. This is the correct command to use to accomplish the task. The other options are incorrect because they either perform different actions (enable, mask, or show) or do not show the status of the service (systemctl show systemd-resolved.service only shows the properties of the service, not the status).

A Linux engineer set up two local DNS servers (10.10.10.10 and 10.10.10.20) and was testing email connectivity to the local mail server using the mail command on a local machine when the following error appeared:
The local machine DNS settings are:
Which of the following commands could the engineer use to query the DNS server to get mail server information?
Explanation:
The command dig @10.10.10.20 example.com mx will query the DNS server to get mail server information. The dig command is a tool for querying DNS servers and displaying the results. The @ option specifies the DNS server to query, in this case 10.10.10.20. The mx option specifies the type of record to query, in this case mail exchange (MX) records, which identify the mail servers for a domain. The domain name to query is example.com. This command will show the MX records for example.com from the DNS server 10.10.10.20. This is the correct command to use to accomplish the task. The other options are incorrect because they either use the wrong syntax (@example.com 10.10.10.20 instead of @10.10.10.20 example.com), the wrong type of record (a or ptr instead of mx), or the wrong domain name (example.com ns instead of example.com mx).
