For example, on Kubuntu, I run:

apt-cache policy open-vm-tools-desktop

and it returns:

open-vm-tools-desktop:
  Installed: (none)
  Candidate: 2:9.4.6-1770165-8ubuntu1

Thank you. Both worked exactly as you described. The rpm -q returned immediate results, as if it was running locally. The dnf info seemed to take much longer, as if it was checking the repositories.

I also was able to use Apper. On Fedora 22 KDE Spin, Apper reports that open-vm-tools-desktop is 9.10.0-4.fc22.

The rpm command uses the local database - it's used to query, install, erase, update local individual packages. The DNF (used to be yum - from Fedora 22 we've transitioned to dnf) command uses the external repository as well as the local. dnf can show you both what's on your system and what's available. It's also what you use to install new packages with, to find dependencies etc.
