The dpkg-____ command will ask configuration questions for a specified package, just as if the package were being installed for the first time.
Correct Answer:
dpkg-reconfigure
Explanation:
The dpkg-reconfigure command is used to reconfigure an already installed package. It asks configuration questions for the package, just as if the package were being installed for the first time. This can be useful if the user wants to change some settings or options for the package without reinstalling it. The dpkg- reconfigure command can also be used to fix a broken package configuration or to restore the default settings.

Which umask value will result in the default access permissions of 600 (rw-------) for files and 700 (rwx------) for directories? (Specify only the numerical umask value.)
Correct Answer:
0077, 077
Explanation:
The umask value that will result in the default access permissions of 600 (rw-------) for files and 700 (rwx------ ) for directories is 077. This is because the umask value is an octal number that represents the permissions that are not given to the files or directories. To calculate the umask value, we need to subtract the desired permissions from the maximum permissions, which are 666 for files and 777 for directories. For example, if we want the files to have the permissions 600 (rw-------), which means read and write for the owner and no permissions for the group and others, we need to subtract 600 from 666, which gives us 066. Similarly, if we want the directories to have the permissions 700 (rwx------), which means read, write, and execute for the owner and no permissions for the group and others, we need to subtract 700 from 777, which gives us 077.
The umask value is the minimum of these two values, which is 077. The first digit of the umask value is for the special permissions, such as setuid, setgid, and sticky bit, and it is usually set to 0. Therefore, the final umask value is 077.
