CompTIA N10-008 Online Questions & Answers

• Question 261:

  A customer has requested Ethernet cabling for a new office building. A technician is dispatched to perform a site survey and does not note any special considerations for the installation. Which of the following cable types will the technician MOST likely recommend for this installation?

  A. Metallic sheathed
  B. Fiber optic
  C. Unshielded twisted pair
  D. Coaxial
  C. Unshielded twisted pair

• Question 262:

  A technician troubleshoots user reports about high latency while trying to access some of the web servers. Which of the following would be the best way for the technician to identify the issue?

  A. Use NetFlow on an edge device to view all traffic data.
  B. Use nslookup and dig to Identify issues.
  C. Use ping, nmap, and traceroute.
  D. Use Wireshark and tcpdump on users' devices to log all data.
  C. Use ping, nmap, and traceroute.

  Explanation/Reference:

  To troubleshoot high latency issues when accessing web servers, a technician should use tools like ping, nmap, and traceroute. Ping can verify the reachability of a server and measure round-trip time. Nmap can scan for open ports and

  detect services running on the server. Traceroute can identify the path traffic takes to reach the server and pinpoint where delays occur.

• Question 263:

  A network manager wants to view network traffic for devices connected to a switch. A network engineer connects an appliance to a free port on the switch and needs to configure the switch port connected to the appliance. Which of the following is the best option for the engineer to enable?

  A. Trunking
  B. Port mirroring
  C. Full duplex
  D. SNMP
  B. Port mirroring

  ---

  Explanation/Reference:

  Port mirroring is a feature that allows a switch to copy the traffic from one or more ports to another port, where a network analyzer or a monitoring device can capture and analyze the traffic. Port mirroring is useful for troubleshooting and security purposes, as it allows the network engineer to see the traffic that is passing through the switch without affecting the normal operation of the network.

• Question 264:

  A technician is troubleshooting an incident regarding a fiber that is connecting two buildings. The technician suspects a break may have occurred midway along the route. Which of the following tools should the technician use to verify the point where the break might be located?

  A. Loopback adapter
  B. OTDR
  C. Cable tester
  D. New SFPs
  B. OTDR

• Question 265:

  Which of the following would MOST likely utilize PoE?

  A. A camera
  B. A printer
  C. A hub
  D. A modem
  A. A camera

  ---

  Explanation/Reference:

  The device that would MOST likely utilize PoE is a camera1. A camera is an example of a powered device (PD) that can receive both data and power from a single Ethernet cable connected to a power sourcing equipment (PSE), such as a switch or an injector. PoE cameras are commonly used for security and surveillance purposes, as they can reduce the cost and complexity of installation and maintenance. PoE cameras can support various features, such as motion detection, night vision, pan-tilt-zoom (PTZ), and remote control

• Question 266:

  A technician is setting up a new router, configuring ports, and allowing access to the Internet. However, none of the users connected to this new router are able to connect to the Internet. Which of the following does the technician need to configure?

  A. Tunneling
  B. Multicast routing
  C. Network address translation
  D. Router advertisement
  C. Network address translation

  ---

  Explanation/Reference:

  Network address translation (NAT): This is required to translate the private IP addresses of the devices connected to the router to a public IP address that can be used to communicate with the internet. Without NAT, devices on the private network would not be able to communicate with the internet.

• Question 267:

  A Chief Information Officer (CIO) is reviewing a proposal to provide access security for the IT department's restricted area. Which of the following is a preventive measure that should be implemented?

  A. Motion detection
  B. Cameras
  C. Biometric lock
  D. Asset tags
  C. Biometric lock

• Question 268:

  An attacker is using an unknown vulnerability that allows malicious actors to utilize the print spooler to gain system privileges on a computer. Which of the following is this scenario an example of?

  A. Honeypot
  B. Zero-day attack
  C. Internal threat
  D. External threat
  B. Zero-day attack

• Question 269:

  A large number of PCs are obtaining an APIPA IP address, and a number of new computers were added to the network. Which of the following is MOST likely causing the PCs to obtain an APIPA address?

  A. Rogue DHCP server
  B. Network collision
  C. Incorrect DNS settings
  D. DHCP scope exhaustion
  D. DHCP scope exhaustion

  ---

  Explanation/Reference:

  B and C are irrelevant to the topic.

  A rogue DHCP server would be handing out addresses from outside to APIPA range, which would most likely cause IP Conflict, which is when 2 or more devices on the same network shares the same IP Address.

  D is correct because when you run out of Addresses to hand out, the DHCP can't do anything and so APIPA takes over and hands out an random address from within the APIPA range.

• Question 270:

  An IT technician successfully connects to the corporate wireless network at a hank. While performing some tests, the technician observes that the physical address of the DHCp server has changed even though the network connection has not been lost. Which of the following would BEST explain this change?

  A. Server upgrade
  B. Duplicate IP address
  C. Scope exhaustion
  D. Rogue server
  D. Rogue server

  ---

  Explanation/Reference:

  A rogue server is a DHCP server on a network that is not under the administrative control of the network staff1. It may provide incorrect IP addresses or other network configuration information to devices on the network, causing them to lose connectivity or be vulnerable to attacks2. The physical address of the DHCP server may change if a rogue server takes over the role of assigning IP addresses to devices on the network. This can be detected by monitoring DHCP traffic or using tools such as RogueChecker2.
