Hello, I went for the CCNA and 200-120 during the test I had asked a laboratory Network Device Security topic. When I wanted to begin to answer the question and test software allow to write orders stuck. Next I pulled it and gave me other questions not answered the question in the subject laboratory-ACL caused the failure. He also called the attention of the invigilator who was with us on the test. He could not help me and asked me to send you a referral about the issue and continue the test. I was getting ready to test a long time learned properly and I also knew the answer. I ask all to Shawn request to take the test again. Waiting for a response as soon as possible and hopefully positive response.
