Question 7
You are a called upon to troubleshoot connectivity problems to a network device on a production floor. You have used ping and traceroute to verify that you cannot connect to the device from the management network. The network is 209.165.202.128/27 and the device has been given the IP address 209.165.202.158 and mask 255.255.255.224. You have verified that you can reach the device with your computer connected to the same switch as the device. What could be the cause of this problem?
- A. The device is set to the wrong subnet mask.
- B. The device is set to the wrong IP address.
- C. The device has no IP default gateway.
- D. The device is connected to a switchport in the wrong VLAN.
Answer : C

- C. The bridge priority is lower than the default value for spanning tree.
- D. All interfaces that are shown are on shared media.
- E. All designated ports are in a forwarding state.
- F. This switch must be the root bridge for all VLANs on this switch.
Answer : ACE
