Passed the CCNA Data Center DCICN 640-911 exam few days ago with 980/1000. There wasn’t anything new for the 640-911 exam itself, but you need to read and understand all the exam questions’ meaning for at least three times, or you will choose the wrong answers. I practiced PassLeader 640-911 dumps (http://www.passleader.com/640-911.html) for two times before taking, which saved me much time in the real test and finally passed exam! Good!

About 5 different new questions, main: 1 Call Home (two essential parameters to configure, I selected email and phone), 1 Cisco ISSU (what is needed to enable ISSU, I selected dual supervisior) … Some questions the answers were changed but nothing that made it difficult ..
