The things to say here are pretty much the same as the last topic. For listener, you can also use netca / netmgr (much faster approaches if the exam does not constraint). But you may also know how to do w/o GUI.
Consider yourself ready when you are able to easily create a static listener using manual edition in less than 1 minute.

Database Administration -> Net Services Reference
Database Administration -> Net Services Administrator's Guide (this one has an example link, very useful)
