Since the package is already installed on the machine, I am of the opinion that yum upgrade will be used. then rpm -qa used for query. that is BD

Another ambiguous question. Select either (A or B) and D as the least worst options. A. 'yum install [packagename]' will not work to upgrade the package if the package is already installed. It just exits saying nothing to do package already installed, even if you've done a yum check-upgrade and can see an newer version of the package is available. You either need to supply the specific newer version number as a suffix to the package name or use the command 'yum install --best [packagename]' to update the package to whatever the latest version available is. B. 'yum upgrade' will upgrade all packages for which newer versions are available, which is not exactly was asked for. 'yum upgrade [packagename]' would accomplish what was asked by updating only the named package (and any of its dependencies). C. uninstalls (e=erase) the named package. Not correct. D. 'rpm -qa' displays ALL installed packages and their versions. It works but is messy. Instead 'rpm -q [packagename]' will display the version of the package requested and nothing more. E/F. apt-get is the wrong tool here.

Yeah, D is a mean-spirited answer. It should be `rpm -q <package name>` since that's how everyone and their dog checks if a RPM was installed. `rpm -qa` makes little to no sense if you have hundreds of RPMs installed. I was thinking it'd be `rpm -e <package name>` because I had no idea what -e did, it just looked more right to me than the nonsense that is using `rpm -qa` to check for a single RPM. If I had experienced this same question on the test without having experienced it here first, I would've gotten it wrong. Mean.

Selected Answer: AB

strange task "-update and install- the new package" A. yum install <package name> => valid because yum is used on RedHat and respect the task "install new package version" B. yum upgrade => valid because check if new package version is installed, if not upgrade it. C. rpm -e <package name> => is for RedHat-like but not valid because: -e means erase D. rpm -qa => is for RedHat-like but not valid because: -qa means query all. Display list ALL installed packages E. apt-get <package name> => not valid because is for Debian-like ( similar to rpm to manage .rpm but using .deb files) F. apt-get upgrade => not valid because is for Debian-like ( similar to rpm to manage .rpm but using .deb files)
