CCNA4 Chapter 9 Exam (v5.03) Answer 2016

  1. A user in a large office calls technical support to complain that a PC has suddenly lost connectivity to the network. The technician asks the caller to talk to nearby users to see if other machines are affected. The caller reports that several immediate neighbors in the same department have a similar problem and that they cannot ping each other. Those who are seated in other departments have connectivity. What should the technician check as the first step in troubleshooting the issue?

    • the power outlet to the PC that is used by the caller
    • the trunks between switches in the wiring closet
    • the status of the departmental workgroup switch in the wiring closet
    • the cable that connects the PC of the caller to the network jack
    • the cable connection between a PC and a network outlet that is used by a neighbor
  2. Which statement describes the physical topology for a 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.
  3.  

  4. When should a network performance baseline be measured?

    • during normal work hours of an organization
    • immediately after the main network devices restarted
    • after normal work hours to reduce possible interruptions
    • when a denial of service attack to the network is detected and blocked
  5. What is a purpose of establishing a network baseline?

    • It provides a statistical average for network performance.
    • It manages the performance of network devices.
    • It creates a point of reference for future network evaluations.
    • It checks the security configuration of network devices.
  6. In which step of gathering symptoms does the network engineer determine if the problem is at the core, distribution, or access layer of the network?

    • Document the symptoms.
    • Determine the symptoms.
    • Gather information.
    • Determine ownership.
    • Narrow the scope.
  7. 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?
    • When did you first notice your email problem?
  8.  

  9. A team of engineers has identified a solution to a significant network problem. The proposed solution is likely to affect critical network infrastructure components. What should the team follow while implementing the solution to avoid interfering with other processes and infrastructure?

    • change-control procedures
    • one of the layered troubleshooting approaches
    • knowledge base guidelines
    • syslog messages and reports
  10. After which step in the network troubleshooting process would one of the layered troubleshooting methods be used?

    • documenting symptoms
    • determining ownership
    • narrowing the scope
    • gathering symptoms from suspect devices
  11. 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
  12. Which troubleshooting method begins by examining cable connections and wiring issues?

    • top-down
    • bottom-up
    • substitution
    • divide-and-conquer
  13.  

  14. Which number represents the most severe level of syslog logging?

    • 0
    • 1
    • 7
    • 10
    • 100
  15. A company is setting up a web site with SSL technology to protect the authentication credentials required to access the web site. A network engineer needs to verify that the setup is correct and that the authentication is indeed encrypted. Which tool should be used?

    • fault-management tool
    • protocol analyzer
    • baselining tool
    • cable analyzer
  16. Which two specialized troubleshooting tools can monitor the amount of traffic that passes through a switch? (Choose two.)

    • TDR
    • digital multimeter
    • NAM
    • portable network analyzer
    • DTX cable analyzer
  17. Which type of tool would an administrator use to capture packets that are going to and from a particular device?

    • NMS tool
    • knowledge base
    • baselining tool
    • protocol analyzer
  18.  

  19. An administrator is troubleshooting an Internet connectivity problem on a router. The output of the show interfaces gigabitethernet 0/0 command reveals higher than normal framing errors on the interface that connects to the Internet. At what layer of the OSI model is the problem likely occurring?

    • Layer 1
    • Layer 2
    • Layer 3
    • Layer 4
    • Layer 7
  20. Users report that the new web site http://www.company1.biz cannot be accessed. The helpdesk technician checks and verifies that the web site can be accessed with http://www.company1.biz:90. Which layer in the TCP/IP model is involved in troubleshooting this issue?

    • application
    • transport
    • internet
    • network access
  21. A user reports that after an OS patch of the networking subsystem has been applied to a workstation, it performs very slowly when connecting to network resources. A network technician tests the link with a cable analyzer and notices that the workstation sends an excessive number of frames smaller than 64 bytes and also other meaningless frames. What is the possible cause of the problem?

    • cabling faults
    • corrupted NIC driver
    • Ethernet signal attenuation
    • corrupted application installation
  22. The newly configured ASBR that connects a company to the Internet has a default route configured and has the default-information originate command entered. Devices connected through this router can access the Internet. The problem is that no other OSPF routers have a default route in the routing table and no other users throughout the organization can access the Internet. What could be the problem?

    • The ASBR does not have OSPF configured.
    • The ASBR does not have an OSPF neighbor.
    • The other routers are not configured to accept LSA type 4s.
    • The ASBR should use the exit_interface argument instead of next-hop on the default route.
  23. A group of Windows PCs in a new subnet has been added to an Ethernet network. When testing the connectivity, a technician finds that these PCs can access local network resources but not the Internet resources. To troubleshoot the problem, the technician wants to initially confirm the IP address and DNS configurations on the PCs, and also verify connectivity to the local router. Which three Windows CLI commands and utilities will provide the necessary information? (Choose three.)

    • arp -a
    • ipconfig
    • nslookup
    • ping
    • telnet
    • tracert
    • netsh interface ipv6 show neighbor
  24. A networked PC is having trouble accessing the Internet, but can print to a local printer and ping other computers in the area. Other computers on the same network are not having any issues. What is the problem?

    • The PC has a missing or incorrect default gateway.
    • The default gateway router does not have a default route.
    • The switch port to which the PC connects has an incorrect VLAN configured.
    • The link between the switch to which the PC connects and the default gateway router is down.
  25. An internal corporate server can be accessed by internal PCs, but not by external Internet users that should have access. What could be the issue?

    • Static NAT has not been configured properly or at all.
    • The server does not have a private IP address assigned.
    • The default gateway router for the server does not have a default route.
