Maybe this data will help. Big Thanx to Tim for compilin this data.
What he has done for us is collected all the job posts for 'network administration' on WORKOPOLIS over a 30 day period. Then he has listed the number of times employers have listed various keywords as part of job requirements.

Of course this data is not exhaustive. Plus, if you are going to be starting as a Systems Support specialist then you want to consider doing your own research for a different job profile like `System Technician`to see what is important for the jOb requirements. Please share your research with me so that we can let the others know too.
:) Happy Holidays
