Since this is third-party YUM repository, certain system administrator may prefer to disable it by default and only install certain package from it when necessary.
$ cat /etc/yum.repos.d/epel* | grep enabled
enabled=0
enabled=0
enabled=0
enabled=1
enabled=0
enabled=0
$ sed -i 's/enabled=1/enabled=0/g' /etc/yum.repos.d/epel*
$ cat /etc/yum.repos.d/epel* | grep enabled
enabled=0
enabled=0

If you've installed any packages from this Yum repository. You should clear all the downloaded cache RPM packages..
$ yum clean all
Unfortunately, to perform any yum commands against this repository, we've to explicitly state the repository for every command. Some examples.
$ yum search --enablerepo=epel ansible
$ yum list --enablerepo=epel | grep epel | grep ansible
$ yum install --enablerepo=epel ansible
Indeed a bit hassle to type all these commands. You can create an alias to reduce the needless typing.
$ alias yumepel="yum --enablerepo='epel'"
$ yumepel search ansible
