MODULE 12 Network Troubleshooting

1. Which statement describes the physical topology for a LAN?

• 
  

• • It depicts the addressing scheme that is employed in the LAN.

  
  

• • It describes whether the LAN is a broadcast or token-passing network.

  
  

• • It defines how hosts and network devices connect to the LAN.

  
  

• • It shows the order in which hosts access the network.

  
  

2. A network engineer is troubleshooting a network problem where users cannot access the FTP server at the same IP address where a website can be successfully accessed. Which troubleshooting method would be the best to apply in this case?

• 
  

• • comparing IP settings on user workstations

  
  

• • top-down

  
  

• • bottom-up

  
  

• • divide-and-conquer

  
  

3. A computer technician performed a number of actions to correct a problem. Some actions did not solve the problem, but eventually a solution was found. What should be documented?

• 
  

• • everything that was done to try to solve the problem

  
  

• • only the solution, because this solved the problem

  
  

• • a description of the problem and solution

  
  

• • only the failed attempts, so that future technicians will know what not to try

  
  

4. A network engineer is troubleshooting a network problem and can successfully ping between two devices. However, Telnet between the same two devices does not work. Which OSI layers should the administrator investigate next?

• 
  

• • all of the layers

  
  

• • from the network layer to the application layer

  
  

• • from the network layer to the physical layer

  
  

• • only the network layer

  
  

5. While designing changes to a data center because of a new IoE implementation, a network administrator has the job of diagramming the new physical topology of the area. What should be included in the physical topology diagram?

• 
  

• • technical specifications of firewalls

  
  

• • the service level agreement from the ISP

  
  

• • cable locations and lengths between servers and switches

  
  

• • the IP addressing scheme for all workstations in the company

  
  

6. A network technician is troubleshooting an email connection problem. Which question to the end-user will provide clear information to better define the problem?

• 
  

• • What kind of equipment are you using to send emails?

  
  

• • How big are the emails you tried to send?

  
  

• • Is your email working now?

  
  

• • When did you first notice your email problem?

  
  

7. Which troubleshooting tool can be used to pinpoint the distance to a break in a network cable?

• 
  

• • network analyzer

  
  

• • network analysis module

  
  

• • cable tester

  
  

• • digital multimeter

  
  

8. Which troubleshooting software is an example of a network management system tool?

• 
  

• • LANsurveyor

  
  

• • CyberGauge

  
  

• • WhatsUp Gold

  
  

• • Wireshark

• What is the purpose of establishing a network baseline?

• • to document and analyze the network traffic

  
  

• • to help monitor and troubleshoot network performance

  
  

• • to provide an inventory of network devices

  
  

• • to verify the configuration of routers and switches on the network

  
  

10. After which step in the network troubleshooting process would one of the layered troubleshooting methods be used?

• 
  

• • determining ownership

  
  

• • narrowing the scope

  
  

• • documenting symptoms

  
  

• • gathering symptoms from suspect devices
