    Passed the JN0-661 (JNCIP-SP) exam recently! Got 65 multiple-choice questions, few new questions, which are not available here!

    Pay close attention to the objective of BGP, many questions on it!

    And, learning the Layer 2/3 VPNs, Class of Service (CoS) and IS-IS deeply and carefully!!!

    At last, I recommend you to learn the NEWEST & VALID PassLeader JN0-661 dumps here:
