The command that will provide the correct information about whether files from the wget package have been altered since they were installed is rpm -V wget. This command will use the rpm utility to verify an installed RPM package by comparing information about the installed files with information from the RPM database. The verification process can check various attributes of each file, such as size, mode, owner, group, checksum, capabilities, and so on. If any discrepancies are found, rpm will report them using a single letter code for each attribute.

The other options are not correct commands for verifying an installed RPM package. The rpm -i wget command is invalid because -i is used to install a package from a file, not to verify an installed package. The rpm -qf wget command will query which package owns wget as a file name or path name, but it will not verify its attributes. The rpm -F wget command will freshen (upgrade) an already installed package with wget as a file name or path name, but it will not verify its attributes. References: rpm(8) - Linux manual page; Using RPM to Verify Installed Packages

The correct answer is A. chmod g+s /home/test

This command will set the setgid bit on the /home/test directory, which means that any file or subdirectory created in the directory will inherit the group ownership of the directory. This way, the group permissions on files created in the directory will be preserved. The chmod command is used to change the permissions of files and directories. The g+s option is used to set the setgid bit for the group.

The other options are incorrect because:

B. chgrp test /home/test

This command will change the group ownership of the /home/test directory to test, but it will not affect the group ownership of files created in the directory. The chgrp command is used to change the group of files and directories. The test /home/test arguments are used to specify the new group and the target directory.

C. chmod 777 /home/test

This command will give read, write, and execute permissions to everyone (owner, group, and others) on the /home/test directory, but it will not affect the group ownership or permissions of files created in the directory. The chmod command is used to change the permissions of files and directories. The 777 argument is an octal number that represents the permissions in binary form.

D. chown -hR test /home/test

This command will change the owner and group of the /home/test directory and all its contents recursively to test, but it will not preserve the original group permissions on files created in the directory. The chown command is used to change the owner and group of files and directories. The -hR option is used to affect symbolic links and operate on all files and directories recursively. The test /home/test arguments are used to specify the new owner and group and the target directory.

The docker exec ls command can be used to verify whether the built container has the app.go file in its root directory. This command will run the ls command inside the specified container and list the files and directories in its root directory. If the app.go file is present, it will be displayed in the output. The docker image inspect command will display information about an image, not a container, and it will not list the files inside the image. The docker container inspect command will display information about a container, not its files. The docker ps command is invalid, as ps does not accept a container name as an argument. References: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 16: Virtualization and Cloud Technologies, page 499.
