CompTIA CompTIA Certifications N10-008 Questions & Answers

• Question 841:

  After a critical power issue, the network team was not receiving UPS status notifications. The network team would like to be alerted on these status changes. Which of the following would be BEST to use tor these notifications?

  A. Traps

  B. MB

  C. NetFlow

  D. Syslog

  Correct Answer: A

  Traps are a type of notification used in network management that allow a network device to send an alert to a network management system (NMS) when certain events occur, such as a change in status or a critical error. Traps are typically

  used to alert the network team to issues that require immediate attention, such as the power issue described in the scenario.

  MIB (Management Information Base) is a database of information used for managing and monitoring network devices. It is not typically used for sending notifications about status changes or other events.

  NetFlow is a protocol used for collecting and exporting information about the flow of network traffic. It is not typically used for sending notifications about status changes or other events.

  Syslog is a protocol used for sending system log messages over a network to a central logging server. It is not typically used for sending notifications about status changes or other events.

• Question 842:

  A network administrator is reviewing the network device logs on a syslog server. The messages are normal but the stamps on the messages are incorrect. Which of the following actions should the administrator take to ensure the log message time stamps are correct?

  A. Change the NTP settings on the network device

  B. Change the time on the syslog server

  C. Update the network device firmware

  D. Adjust the timeout settings on the syslog server

  E. Adjust the SSH settings on the network device.

  Correct Answer: A

  NTP (Network Time Protocol) is used to synchronize the time on network devices. If the time stamps on the syslog server are incorrect, it is likely that the NTP settings on the network device are incorrect. By updating the NTP settings on the network device, the time stamps on the syslog server will be corrected.

• Question 843:

  Network connectivity in an extensive forest reserve was achieved using fiber optics. A network fault was detected, and now the repair team needs to check the integrity of the fiber cable. Which of me following actions can reduce repair time?

  A. Using a tone generator and wire map to determine the fault location

  B. Using a multimeter to locate the fault point

  C. Using an OTDR In one end of the optic cable to get the liber length information

  D. Using a spectrum analyzer and comparing the current wavelength with a working baseline

  Correct Answer: C

  Using an OTDR (Optical Time Domain Reflectometer) is the most effective way to reduce repair time when trying to locate a fault in a fiber optic cable. The OTDR sends a pulse of light down the fiber optic cable and measures the time it takes for the light to be reflected back. By analyzing the reflections, the OTDR can determine the location of any faults or breaks in the cable. This allows the repair team to quickly and accurately locate the fault point, which can significantly reduce the time needed for repairs.

• Question 844:

  Due to a surge in business, a company is onboarding an unusually high number of salespeople. The salespeople are assigned desktops that are wired to the network. The last few salespeople to be onboarded are able to access corporate materials on the network but not sales-specific resources. Which of the following is MOST likely the cause?

  A. The switch was configured with port security.

  B. Newly added machines are running into DHCP conflicts.

  C. The IPS was not configured to recognize the new users.

  D. Recently added users were assigned to the wrong VLAN

  Correct Answer: D

  In this scenario, the salespeople are assigned desktops that are wired to the network. The fact that the salespeople can access corporate materials on the network suggests that their desktops are able to communicate with the network. However, they cannot access sales-specific resources, which could be an indication that they have been assigned to the wrong VLAN.

  VLANs are used to segment a network into smaller logical pieces, which helps to improve security and network performance. VLANs are often used to group devices by function, department, or location. When a new group of users, such as the salespeople in this scenario, is added to a network, they need to be assigned to the appropriate VLAN to access resources that are specific to their role.

  If the recently added users were assigned to the wrong VLAN, they would not be able to access resources that are specific to their role. In this case, it is likely that the desktops were configured to use the wrong VLAN, which is preventing the salespeople from accessing sales-specific resources.

• Question 845:

  Which of the following is the MOST cost-effective alternative that provides proper cabling and supports gigabit Ethernet devices?

  A. Twisted cable with a minimum Cat 5e certification

  B. Multimode fiber with an SC connector

  C. Twinaxial cabling using an F-type connector

  D. Cable termination using TIA/EIA-568-B

  Correct Answer: A

  twisted cable with a minimum Cat 5e certification is the MOST cost-effective alternative that provides proper cabling and supports gigabit Ethernet devices.

• Question 846:

  An employee working in a warehouse facility is experiencing interruptions in mobile applications while walking around the facility. According to a recent site survey, the WLAN comprises autonomous APs that are directly connected to the internet, providing adequate signal coverage. Which of the following is the BEST solution to improve network stability?

  A. Implement client roaming using an extended service deployment employing a wireless controller.

  B. Remove omnidirectional antennas and adopt a directional bridge.

  C. Ensure all APs of the warehouse support MIMO and Wi-Fi 4.

  D. Verify that the level of EIRP power settings is set to the maximum permitted by regulations.

  Correct Answer: A

  Client roaming refers to the ability of a wireless device to seamlessly connect to a different access point (AP) as the user moves around the facility. This can help to improve network stability and reduce interruptions in mobile applications. An extended service deployment is a type of wireless network configuration that uses multiple APs to cover a large area, such as a warehouse facility. By using a wireless controller to manage the APs, the network can be better optimized for client roaming, which can improve network stability.

  "Roaming With multiple WAPs in an ESS, clients will connect to whichever WAP has the strongest signal. As clients move through the space covered by the broadcast area, they will change WAP connections seamlessly, a process called roaming."

• Question 847:

  Which of the following OSI model layers is where a technician would view UDP information?

  A. Physical

  B. Data link

  C. Network

  D. Transport

  Correct Answer: D

  Transport. The transport layer, specifically the User Datagram Protocol (UDP) is responsible for end-to-end communication and data transfer between applications on different devices. It's in this layer where a technician would view UDP information.

• Question 848:

  A technician is configuring a wireless network and needs to ensure users agree to an AUP before connecting. Which of the following should be implemented to achieve this goal?

  A. Captive portal

  B. Geofencing

  C. Wireless client isolation

  D. Role-based access

  Correct Answer: A

  A captive portal is a web page that is displayed to users before they are able to access the internet or other network resources. It is commonly used to require users to agree to an Acceptable Use Policy (AUP) before they are able to connect to a wireless network.

• Question 849:

  A technician installed an 8-port switch in a user's office. The user needs to add a second computer in the office, so the technician connects both PCs to the switch and connects the switch to the wall jack.
