QUESTION NO: 85
You are configuring a fiber connection between two Cisco Catalyst 3750 switches on which UDLD is disabled. You connect both the transmit and receive connectors on one end of the cable to port 1/0/9 on SwitchA. However, you accidentally connect the transmit connector from SwitchA to the receive connector on port 1/0/7 on SwitchB and the receive connector from SwitchA to the transmit connector on port 1/0/8 on SwitchB. Which of the following statements are true? (Select 2 choices.)
A. Issuing the show cdp neighbors command on SwitchA and SwitchB will indicate that none of the ports are connected.
B. Issuing the show cdp neighbors command on SwitchB will indicate that port 1/0/7 on SwitchB is connected to port 1/0/9 on SwitchA.
C. Issuing the show cdp neighbors command on SwitchA will indicate that port 1/0/9 on SwitchA is connected to port 1/0/7 on SwitchB.
D. Issuing the show cdp neighbors command on SwitchB will indicate that port 1/0/8 on SwitchB is connected to port 1/0/9 on SwitchA.
E. Issuing the show cdp neighbors command on SwitchA will indicate that port 1/0/9 on SwitchA is connected to port 1/0/8 on SwitchB.
