Gosh! There are so many reasons to like them

I am happy that i decided to give Riverbed Certified Solutions Professional - Network Performance Management certification exam or else i would not have known about Edusum. This is a site that every person appearing for Network Performance Management (NPM) should know. It is helpful not only before but also after giving the exam. It made me aware of topics that helped me at my workplace too. My score in the exam was 91%.
