From the man yum output (man is what is what you should probably check out in the first place for any command before asking it there):
-q, --quiet Run without output. Note that you likely also want to use -y.
So in essence this option prevents yum from outputting anything to standard file descriptors (STDOUT, STDERR). In practice that means you won't see any output in console.
man also references -y option:
-y, --assumeyes Assume yes; assume that the answer to any question which would be asked is yes. Configuration Option: assumeyes
So -y option automatically answers yes to any console prompt that yum makes.
Together yum -qy would allow you to run yum without any output and manual confirmation which makes it quite handy for automation scripts.
It's used to run yum without output. It's typically used with -y
man yum?
