CompTIA CompTIA Certifications N10-008 Questions & Answers

• Question 461:

  An ISP configured an internet connection to provide 20Mbps, but actual data rates are occurring at 10Mbps and causing a significant delay in data transmission. Which of the following specifications should the ISP check?

  A. Throughput

  B. Latency

  C. Bandwidth

  D. Jitter

  Correct Answer: A

• Question 462:

  A technician is investigating a misconfiguration on a Layer 3 switch. When the technician logs in and runs a command, the following data is shown:

  

  Which of the following commands generated this output?

  A. show route

  B. show config

  C. show interface

  D. tcpdump

  E. netstat -s

  Correct Answer: A

  The command that generated this output is "show route".

  The output shows the routing table entries for the switch, with the network address, next hop IP address, and outgoing interface for each route. This information is used by the switch to determine the best path for forwarding packets to their destination.

• Question 463:

  An IT technician is working on a support ticket regarding an unreachable website. The technician has utilized the ping command to the website, but the site is still unreachable. Which of the following tools should the technician use NEXT?

  A. ipconfig

  B. tracert

  C. arp

  D. netstat

  Correct Answer: B

  Use Traceroute or MTR: Traceroute (Windows) or MTR (Linux/macOS) can provide more detailed information about the network path between your computer and the web server. This can help identify where the connection is failing.

• Question 464:

  Which of the following default ports is MOST likely used to send availability and environmental messages about specific devices across the network?

  A. 23

  B. 53

  C. 389

  D. 514

  E. 3306

  Correct Answer: D

• Question 465:

  A network architect is developing documentation for an upcoming IPv4/IPv6 dual-stack implementation. The architect wants to shorten the following IPv6 address: ef82:0000:0000:0000:0000:1ab1:1234:1bc2. Which of the following is the MOST appropriate shortened version?

  A. ef82:0:1ab1:1234:1bc2

  B. ef82:0::1ab1:1234:1bc2

  C. ef82:0:0:0:0:1ab1:1234:1bc2

  D. ef82::1ab1:1234:1bc2

  Correct Answer: D

  The most appropriate shortened version of the given IPv6 address is ef82:0::1ab1:1234:1bc2. This version uses the "::" notation to replace the consecutive groups of zeros, which helps simplify the address while still accurately representing the original address.

• Question 466:

  A newly installed multifunction copier needs to be set up so scanned documents can be emailed to recipients. Which of the following ports from the copier's IP address should be allowed?

  A. 22

  B. 25

  C. 53

  D. 80

  Correct Answer: B

  Port 25 is the port number that is commonly used for Simple Mail Transfer Protocol (SMTP), which is a protocol that allows sending and receiving email messages over a network1. Port 25 from the copier's IP address should be allowed so

  that scanned documents can be emailed to recipients.

  Port 22 is the port number that is commonly used for Secure Shell (SSH), which is a protocol that allows secure and encrypted remote access and control of a device over a network1. Port 22 from the copier's IP address is not necessary for

  emailing scanned documents.

  Port 53 is the port number that is commonly used for Domain Name System (DNS), which is a protocol that allows resolving domain names to IP addresses and vice versa on a network1. Port 53 from the copier's IP address is not necessary

  for emailing scanned documents.

  Port 80 is the port number that is commonly used for Hypertext Transfer Protocol (HTTP), which is a protocol that allows transferring web pages and other resources over a network1. Port 80 from the copier's IP address is not necessary for

  emailing scanned documents.

• Question 467:

  Which of the following has the capability to centrally manage configuration, logging, and firmware versioning for distributed devices?

  A. WLAN controller

  B. Load balancer

  C. SIEM solution

  D. Syslog server

  Correct Answer: A

  A WLAN controller is a device that manages and controls multiple wireless access points (WAPs) in a wireless LAN (WLAN). A WLAN controller has the capability to centrally manage configuration, logging, and firmware versioning for

  distributed WAPs. A WLAN controller can also provide load balancing, security, and quality of service (QoS) for the WLAN.

• Question 468:

  Which of the following is the MOST effective security control to keep a company's physical perimeter protected against intrusions leveraged by social-engineering techniques?

  A. Employee training

  B. Biometric lockers

  C. Access control vestibule

  D. Motion detection

  Correct Answer: A

• Question 469:

  A PC and a network connectivity, and a help desk technician is attempting to resolve the issue. The technician plans to run a constant ping command from a Windows workstation while testing various possible reasons for the connectivity issue. Which of the following should the technician use?

  A. ping -w

  B. ping -i

  C. ping -s

  D. ping -t

  Correct Answer: D

  The ping -t command is used in the Windows command prompt (CMD) to continuously ping a target IP address or domain name until the command is manually stopped by the user. The -t option essentially creates an ongoing loop of ping requests, providing a real-time display of round-trip times and potential packet loss. This can be useful for monitoring network stability and diagnosing intermittent connectivity issues over an extended period.

• Question 470:

  An AP uses a 98ft (30m) Cat 6 cable to connect to an access switch. The cable is wired through a duct close to a three-phase motor installation. Anytime the three-phase is turned on, all users connected to the switch experience high latency on the network. Which of the following is MOST likely the cause of the issue?

  A. Interference

  B. Attenuation

  C. Open circuit

  D. Short circuit

  Correct Answer: A

  Interference is a phenomenon that occurs when unwanted signals or noise affect the transmission or reception of data signals on a network. Interference can cause network issues such as high latency, low throughput, packet loss, or errors. Interference can be caused by various sources, such as electromagnetic fields, radio waves, power lines, or electrical devices. In this scenario, the three-phase motor installation is a source of interference that affects the Cat 6 cable that connects the AP to the access switch. The cable is wired through a duct close to the motor installation, which exposes it to the electromagnetic fields generated by the motor. Anytime the motor is turned on, the interference causes high latency for all users connected to the switch.
