Netwoking courses are short in duration. It is always best to look at what is hot. Look up the job announcements on three Web sites in areas of Netwoking and note the key skills / certifications they are looking for. If you have adequate qualifications, apply, or you know what course to do. The skill fad changes over night. And one will end up in a goose chase. By the time you catch one, the tech is too old. So where do you go from here.

Look at the technical skill enhancement requirements in your own company. And perhaps learn at their cost and also contribute there on. The problem with internal netwoking people is that while their strengths get recognized, the weaknesses too. The key people if they keep having network problems, their impressions are poor. So, give that extra bit of care and also do routine and regular checks so that every thing is up and running. In todays scenario, do not look for job changes.

Your counsel.
