| | Refer to the exhibit. A new HR server has just been physically |
| | installed and configured in the data center by a vendor. The |
| | vendor certified that the server has passed all internal quality |
| | checks. The application console of the server indicates that the |
| | application has loaded and is functioning normally. However, in |
| | the initial client testing, the HR department workers report |
| | that the application is completely non-functional. The server is |
| | also unable to get to the Internet to perform updates. Which |
| | troubleshooting efforts are appropriate for these symptoms? |
| | |
| | The lack of Internet connectivity indicates a likely problem in |
| | the lower layers. Begin with physical connectivity on the server |
| | and proceed with a bottom-up methodology. |
| | |
| 12 | Narrow the scope of the investigation by ensuring that no other |
| | general connectivity problems exist between the affected clients |
| | and other company resources. Use a divide-and-conquer approach |
| | by checking the functionality of the intervening switches, |
| | beginning with the physical layer. |
| | |
| | Because an external vendor installed the server increases the |
| | odds of an installation error. Use a top-down methodology by |
| | having the vendor reinstall and check each application, and then |
| | follow the layers down through the physical layer. |
| | |
| | Isolate the problem area by obtaining and installing a protocol |
| | analyzer on the server. Coordinate with the test users to |
| | capture application traffic. Have the vendor analyze the |
| | captured traffic to determine the problem. |

| | Refer to the exhibit. The SSH connections between the remote user |
| | and the server are failing. The correct configuration of NAT has |
| | been verified. What is the most likely cause of the problem? |
| | |
| | SSH is unable to pass through NAT. |
| 13 | |
| | There are incorrect access control list entries. |
| | |
| | The access list has the incorrect port number for SSH. |
| | |
| | The ip helper command is required on S0/0/0 to allow inbound |
| | connections. |
