The lsscsi command can list the SCSI devices on the system, along with their size and device name. The -s option shows the size of each device. The administrator can look for the device that has a size of 500G and note its device name.

An administrator accidentally installed the httpd RPM package along with several dependencies. Which of the following options is the best way for the administrator to revert the package

installation?

dnf clean all

rpm -e httpd

apt-get clean

yum history undo last

The yum history undo last command will undo the last transaction, which in this case is the installation of the httpd RPM package and its dependencies. This will remove the packages that were installed and restore the previous state of the system.

On RPM-based systems like Red Hat or CentOS, repository configuration is handled via yum or dnf. The main configuration file is /etc/yum.conf, while individual repository files are stored in /etc/yum.repos.d/. These files dictate where packages are fetched from.

The commandsetfacl -m g:finance:rw filewill permanently fix the access issue while limiting access to IT and finance department employees. Thesetfaclcommand is a tool for modifying the access control lists (ACLs) of files and directories on Linux systems. The ACLs are a mechanism that allows more fine-grained control over the permissions of files and directories than the traditional owner-group-others model. The-moption specifies the modification to the ACL. Theg:finance:rwmeans that the group named finance will have read and write permissions on the file. Thefileis the name of the file to modify, in this case /opt/work/file. The commandsetfacl -m g:finance:rw filewill add an entry to the ACL of the file that will grant read and write access to the finance group. This will fix the access issue and allow the finance employees to access the file. The command will also preserve the existing permissions of the file, which means that the IT employees will still have read and write access to the file. This will limit the access to IT and finance department employees and prevent unauthorized access from other users. This is the correct command to use to accomplish the task. The other options are incorrect because they either do not fix the access issue (chattr +i fileorchown it:finance file) or do not limit the access to IT and finance department employees (chmod 666 file).:CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 11: Managing File Permissions and Ownership, page 352.

The user1 password is expired. This can be inferred from the output of the chage -l user1 command, which shows the password expiration information for user1. The output shows that the password expired on 2020-10-01, and the account expired on 2020-10-08. This means that user1 cannot log in to the server unless the password and account are reactivated by the system administrator.

The other options are not correct based on the outputs above. User1 does not need to set a long password, because the output of the passwd -S user1 command shows that the password has a minimum length of 5 characters, which is met by user1's password. User1 is not in the incorrect group, because the output of the groups user1 command shows that user1 belongs to the app group, which is presumably the correct group for accessing the server. The user1 shell assignment is not incorrect, because the output of the grep user1 /etc/passwd command shows that user1 has /bin/bash as the default shell, which is a valid and common shell for Linux users.

The git checkout -b staging command creates a new branch called staging and switches to it. This is useful when you want to create a new branch locally and begin working on it. The -b flag is used to create the branch if it doesn't exist.
