CompTIA CompTIA Certifications N10-008 Questions & Answers

• Question 1001:

  A technician is connecting DSL for a new customer. After installing and connecting the on-premises equipment, the technician verifies DSL synchronization. When connecting to a workstation, however, the link LEDs on the workstation and modem do not light up. Which of the following should the technician perform during troubleshooting?

  A. Identify the switching loops between the modem and the workstation.

  B. Check for asymmetrical routing on the modem.

  C. Look for a rogue DHCP server on the network.

  D. Replace the cable connecting the modem and the workstation.

  Correct Answer: D

  If the link LEDs on the workstation and modem do not light up when connecting to a workstation, it could indicate a problem with the cable connecting them. The cable could be damaged, defective, or incompatible with the devices. A technician should replace the cable with a known good one and check if the link LEDs light up. If not, the problem could be with the network interface cards (NICs) on the workstation or modem. References: https://www.comptia.org/blog/whatis-link-light

• Question 1002:

  An IT technician suspects a break in one of the uplinks that provides connectivity to the core switch. Which of the following command-line tools should the technician use to determine where the incident is occurring?

  A. nslookup

  B. show config

  C. netstat

  D. show interface

  E. show counters

  Correct Answer: D

  show interface is a command-line tool that displays information about the status, configuration, and statistics of an interface on a network device. A technician can use show interface to determine where the incident is occurring in a network by checking the uplink status, speed, duplex mode, errors, collisions, and other parameters of each interface.

• Question 1003:

  A company requires a disaster recovery site to have equipment ready to go in the event of a disaster at its main datacenter. The company does not have the budget to mirror all the live data to the disaster recovery site. Which of the following concepts should the company select?

  A. Cold site

  B. Hot site

  C. Warm site

  D. Cloud site

  Correct Answer: C

  A warm site is a type of disaster recovery site that has equipment ready to go in the event of a disaster at the main datacenter, but does not have live data or applications. A warm site requires some time and effort to restore the data and services from backups, but it is less expensive than a hot site that has live data and applications. A cold site is a disaster recovery site that has no equipment or data, and requires a lot of time and money to set up after a disaster. A cloud site is a disaster recovery site that uses cloud computing resources to provide data and services, but it may have issues with bandwidth, latency, security, and cost.

• Question 1004:

  A technician has started a major network project to upgrade to a higher throughput standard. The technician will need to install new patch panels and breakout boxes to support this inlrastructure. Which of the following layers of the OSI model is the technician addressing at this stage of the upgrade?

  A. Physical

  B. Transport

  C. Network

  D. Data link

  Correct Answer: A

• Question 1005:

  Which of the following attacks encrypts user data and requires a proper backup implementation to recover?

  A. DDoS

  B. Phishing

  C. Ransomware

  D. MAC spoofing

  Correct Answer: C

  Ransomware is a type of malware that encrypts user data and demands a ransom for its decryption. Ransomware can prevent users from accessing their files and applications, and cause data loss or corruption. A proper backup implementation is essential to recover from a ransomware attack, as it can help restore the encrypted data without paying the ransom or relying on the attackers' decryption key.

• Question 1006:

  A network administrator wants to analyze attacks directed toward the company's network. Which of the following must the network administrator implement to assist in this goal?

  A. A honeypot

  B. Network segmentation

  C. Antivirus

  D. A screened subnet

  Correct Answer: A

  A honeypot is a decoy system that is intentionally left vulnerable or exposed to attract attackers and divert them from the real targets. A honeypot can also be used to collect information about the attackers' techniques and motives. A network administrator can implement a honeypot to analyze attacks directed toward the company's network, as a honeypot can help identify the source, target, method, and impact of an attack, as well as provide recommendations for remediation.

• Question 1007:

  A network administrator needs to keep track of the locations of installed network equipment. Which of the following would be the BEST method to accomplish this task?

  A. Tamper detection

  B. Asset tags

  C. Video surveillance

  D. Motion detection

  Correct Answer: B

• Question 1008:

  The security department is looking to install a new IP-based camera. Plugging the camera into the available Ethernet jack does not power on the camera. Upon further investigation, the cable tests fine, and it does provide power to a VoIP

  phone.

  Which of the following is MOST likely causing the issue?

  A. The brown pair UTP has a short.

  B. The camera requires 802. 3at power

  C. The camera requires Cat 7 cabling.

  D. The switchport has PoE disabled.

  Correct Answer: C

• Question 1009:

  A technician is implementing a new wireless network to serve guests at a local office. The network needs to provide Internet access but disallow associated stations from communicating with each other. Which of the following would BEST accomplish this requirement?

  A. Wireless client isolation

  B. Port security

  C. Device geofencing

  D. DHCP snooping

  Correct Answer: A

  Wireless client isolation is a feature on wireless routers that limits the connectivity between wireless devices connected to the same network. It prevents them from accessing resources on other wireless or wired devices, as a security measure to reduce attacks and threats. This feature can be useful for guest and BYOD SSIDs, but it can also be disabled on the router's settings.
