CompTIA N10-008 Online Questions & Answers

• Question 481:

  A technician needs to configure a routing protocol for an internet-facing edge router. Which of the following routing protocols will the technician MOST likely use?

  A. BGP
  B. RIPv2
  C. OSPF
  D. EIGRP
  A. BGP

  ---

  Explanation/Reference:

  Border Gateway Protocol (BGP) is used to Exchange routing information for the internet and is the protocol used between ISP which are different ASes. The protocol can connect together any internetwork of autonomous system using an arbitrary topology.

• Question 482:

  Which of the following should a network administrator configure when adding OT devices to an organization's architecture?

  A. Honeynet
  B. Data-at-rest encryption
  C. Time-based authentication
  D. Network segmentation
  D. Network segmentation

  ---

  Explanation/Reference:

  Network segmentation is the process of dividing a network into smaller subnets or segments, each with its own security policies and access controls. This can help isolate OT devices from IT devices, guest networks, and other potential

  threats, as well as improve network performance and efficiency. Network segmentation is a recommended security practice for OT environments, as it can limit the attack surface, contain the damage of a breach, and comply with regulatory

  standards.

• Question 483:

  A network technician receives a report from the server team that a server's network connection is not working correctly. The server team confirms the server is operating correctly except for the network connection. The technician checks the switchport connected to the server and reviews the following data;

  

  Which of the following should the network technician perform to correct the issue?

  A. Replace the Cat 5 patch cable with a Cat 6 cable
  B. Install a crossover cable between the server and the switch
  C. Reset the switchport configuration.
  D. Use NetFlow data from the switch to isolate the issue.
  E. Disable MDIX on the switchport and reboot the server.
  A. Replace the Cat 5 patch cable with a Cat 6 cable

  ---

  Explanation/Reference:

  "Bad cables, incorrect pinouts, or bent pins: Faulty cables (with electrical characteristics preventing successful transmission) or faulty connectors (which do not properly make connections) can prevent successful data transmission at Layer 1.

  A bad cable could simply be an incorrect category of cable being used for a specific purpose. For example, using a Cat 5 cable (instead of a Cat 6 or higher cable) to connect two 1000BASE-TX devices would result in data corruption. Bent pins in a connector or incorrect pinouts could also cause data to become corrupted."

• Question 484:

  Which of the following is most closely associated with attempting to actively prevent network intrusion?

  A. IDS
  B. Firewall
  C. IPS
  D. VPN
  C. IPS

• Question 485:

  Which of the following is the next step to take after successfully testing a root cause theory?

  A. Determine resolution steps.
  B. Duplicate the problem in a lab.
  C. Present the theory for approval.
  D. Implement the solution to the problem.
  A. Determine resolution steps.

  ---

  Explanation/Reference:

  Once a root cause theory has been tested and verified, the next step is to devise a plan for resolving the identified issue or problem. This involves determining the specific steps or actions necessary to implement a solution based on the validated theory. It precedes the actual implementation of the solution to address the problem effectively and prevent its recurrence.

• Question 486:

  Two new network switches located in different buildings are connected together with single-mode fiber. However, no link exists between the two switches. Which of the following steps should the technician perform FIRST to troubleshoot the issue?

  A. Reverse TX/RX on the fiber patch cord at one building.
  B. Replace the fiber patch cords in both buildings.
  C. Clean the fiber patch cord connectors in both buildings.
  D. Connect the fiber patch cord to an OTDR at one building.
  C. Clean the fiber patch cord connectors in both buildings.

  ---

  Explanation/Reference:

  The FIRST step the technician should perform to troubleshoot the issue is C. Clean the fiber patch cord connectors in both buildings.

  Dirty or contaminated fiber patch cord connectors can cause signal loss and poor network performance, and may even prevent a link from being established. Before trying any other troubleshooting steps, it is important to ensure that the fiber patch cord connectors are clean and free of debris.

• Question 487:

  After running a Cat 8 cable using passthrough plugs, an electrician notices that connected cables are experiencing a lot of cross talk. Which of the following troubleshooting steps should the electrician take first?

  A. Inspect the connectors for any wires that are touching or exposed.
  B. Restore default settings on the connected devices.
  C. Terminate the connections again.
  D. Check for radio frequency interference in the area.
  A. Inspect the connectors for any wires that are touching or exposed.

  ---

  Explanation/Reference:

  The electrician should first inspect the connectors for any wires that are touching or exposed. Cross talk issues can occur if there is improper termination, exposed wires, or if wires are not properly separated within the connectors. Checking the connectors for correct wiring and ensuring there is no physical contact between wires is a crucial step in troubleshooting cross talk in a network cable.

• Question 488:

  Which of the following transceiver types can support up to 40Gbps?

  A. SFP+
  B. QSFP+
  C. QSFP
  D. SFP
  B. QSFP+

  ---

  Explanation/Reference:

  QSFP+ (Quad Small Form-factor Pluggable Plus) is a type of transceiver that supports data transfer rates up to 40 Gbps. It is an upgraded version of the original QSFP transceiver, which supports up to 4 Gbps. SFP+ (Small Form-factor Pluggable Plus) is another type of transceiver that supports data transfer rates up to 10 Gbps. It is an upgraded version of the original SFP transceiver, which supports up to 1 Gbps.

• Question 489:

  A recent vulnerability was discovered in the code a company is running on its network devices. The vendor has released a security patch to address the vulnerability. To ensure an unaltered version of the patch is downloaded, which of the following should the network technician validate before installing the patch?

  A. Date the patch was created
  B. Version of the patch
  C. Hash values of the patch
  D. Change log for the patch
  C. Hash values of the patch
