Question No: 101 – (Topic 4)

Two weeks after installation, a network technician is now unable to log onto any of the newly installed company switches. The technician suspects that a malicious user may have changed the switches#39; settings before they were installed in secure areas. Which of the following is the MOST likely way in which the malicious user gained access to the switches?

  1. Via SSH using the RADIUS shared secret

  2. Via HTTP using the default username and password

  3. Via console using the administrator#39;s password

  4. Via SNMP using the default RO community

Answer: B Explanation:

A new network switch is accessed via HTTP to perform the initial configuration. The username and password used is a factory default.

Question No: 102 CORRECT TEXT – (Topic 4)

Question No: 103 – (Topic 4)

A PC technician has installed a new network printer that was preconfigured with the correct static IP address, subnet mask, and default gateway. The printer was installed with a new cable and appears to have link activity, but the printer will not respond to any network communication attempts. Which of the following is MOST likely the cause of the problem?

  1. Damaged cable

  2. Duplex mismatch

  3. Incorrect VLAN assignment

  4. Speed mismatch

Answer: C Explanation:

If a port is accidentally assigned to the wrong VLAN in a switch, it’s as if that client was magicallytransported to another place in the network. This would explain the inability to communication with the printer, as it is on a different VLAN.

Question No: 104 – (Topic 4)

A network technician is using a network monitoring system and notices that every device on a particular segment has lost connectivity. Which of the following should the network technician do NEXT?

  1. Establish a theory of probable cause.

  2. Document actions and findings.

  3. Determine next steps to solvethe problem.

  4. Determine if anything has changed.

    Answer: D Explanation:

    The technician has already identified the symptom: Loss of connectivity on a specific network segment. The next step in identifying the problem is to “Determine if anything haschanged”.

    Common troubleshooting steps and procedures:

    1. Identify the problem. Information gathering. Identify symptoms. Question users.

      Determine if anything has changed.

    2. Establish a theory of probable cause. Question the obvious.

    3. Test the theoryto determine cause:

      When the theory is confirmed, determine the next steps to resolve the problem. If theory is not confirmed, re-establish a new theory or escalate.

    4. Establish a plan of action to resolve the problem and identify potential effects.

    5. Implement the solution or escalate as necessary.

    6. Verify full system functionality and if applicable implement preventive measures.

    7. Document findings, actions, and outcomes.

      Question No: 105 – (Topic 4)

      A network technician has detected duplicate IP addresses on the network. After testing the behavior of rogue DHCP servers, the technician believes that the issue is related to an unauthorized home router. Which of the following should the technician do NEXT in the troubleshooting methodology?

      1. Document the findings and action taken.

      2. Establish a plan to locate the rogue DHCP server.

      3. Remove the rogue DHCP server from the network.

      4. Identify the root cause of the problem.

        Answer: B Explanation:

        By testing the behavior of rogue DHCP servers and determining that the issue is related to an unauthorized home router, thetechnician has completed the third step in the 7-step troubleshooting process. The next step is to establish a plan of action to resolve the problem and identify potential effects. Establishing a plan to locate the rogue DHCP server meets the requirementsof this step.

        1. Identify the problem. Information gathering.

          Identify symptoms. Question users.

          Determine if anything has changed.

        2. Establish a theory of probable cause. Question the obvious.

        3. Test the theory to determine cause:

          When the theory isconfirmed, determine the next steps to resolve the problem. If theory is not confirmed, re-establish a new theory or escalate.

        4. Establish a plan of action to resolve the problem and identify potential effects.

        5. Implement the solution or escalate as necessary.

        6. Verify full system functionality and if applicable implement preventive measures.

        7. Document findings, actions, and outcomes.

          Question No: 106 – (Topic 4)

          A technician is troubleshooting a wired device on the network. The technician notices that the link light on the NIC does not illuminate. After testing the device on a different RJ-45 port, the device connects successfully. Which of the following is causing this issue?

          1. EMI

          2. RFI

          3. Cross-talk

          4. Bad wiring

Answer: D Explanation:

The question states that the device worked on a different port. This indicates that the wiring is faulty.

Question No: 107 – (Topic 4)

A network technician has been assigned to install an additional router on a wireless network. The router has a different SSID and frequency. All users on the new access point and the main network can ping each other and utilize the network printer, but all users on the new router cannot get to the Internet. Which of the following is the MOST likely cause of this issue?

  1. The gateway is misconfigured on the new router.

  2. The subnet mask is incorrect on the new router.

  3. The gateway is misconfigured on the edge router.

  4. The SSID is incorrect on the new router.

Answer: A Explanation:

A missing or incorrect default gateway parameter limits communication to the local segment.

The question states: “All users on the new access point and the main network can ping each other and utilize the network printer, but all users on the new router cannot get to the Internet”.

Question No: 108 – (Topic 4)

A network technician is troubleshooting a problem at a remote site. It has been determined that the connection from router A to router B is down. The technician at the remote site re- terminates the CAT5 cable that connects the two routers as a straight through cable. The cable is then tested and is plugged into the correct interface. Which of the following would be the result of this action?

  1. The normal amount of errors and the connection problem has been resolved.

  2. The interface status will indicate that the port is administratively down.

  3. The traffic will flow,but with excessive errors.

  4. The interface status will show line protocol down.

Answer: D Explanation:

Devices of different types are connected with a straight through cable (patch cable). In this case, it is used to connect two devices of the same type. It is for this reason that the interface will display the line protocol down status.

Question No: 109 – (Topic 4)

While troubleshooting a connectivity issue, a network technician determines the IP address of a number of workstations is 169.254.0.0/16 and the workstations cannot access the Internet. Which of the following should the technician check to resolve the problem?

  1. Default gateway address

  2. Misconfigured DNS

  3. DHCP server

  4. NIC failure

Answer: C Explanation:

If a DHCP server fails, the workstations are assigned an address from the 169.254.0.0 address range by Automatic Private IP Addressing (APIPA). APIPA also configures a suitable subnet mask, but it doesn’t configure the system with a default gateway address. This allows communication on the local network, but not externally.

Question No: 110 – (Topic 4)

A user connects to a wireless network at the office and is able to access unfamiliar SMB shares and printers. Which of the following has happened to the user?

  1. The user is connected using the wrong channel.

  2. The user is connected to the wrong SSID.

  3. The user is experiencing an EMI issue.

  4. The user is connected to the wrong RADIUS server.

Answer: B

Explanation:

The user is connecting to an SSID assignedto a different subnet. Therefore, the user has access to SMB shares and printers that are not recognizable.
