There was a time when people had not heard about the ANS-C00 mock quizzes online. People who were like me were wasting their time on the PDF sample questions or the dump sites. Some other did not practice at all and went straight away to attempt the Advanced Networking Specialty certification exam. I still remember the day when i first landed on vmexam.com. It was like a gift for me and i started jumping with joy. My kid thought that i have gone crazy. Today when my kid has grown up and is attempting the certification, he very well knows what to choose for practicing.
