CompTIA CompTIA Certifications N10-008 Questions & Answers

• Question 181:

  Which of the following would most likely be considered for an IDF installation in a secure facility?

  A. Full-size body scanners

  B. Iris scanner

  C. RFID badge readers

  D. Smart deadbolt

  Correct Answer: C

  An Intermediate Distribution Frame (IDF) in a secure facility typically houses networking equipment and connections. In this context, security measures are likely to involve access control to the networking infrastructure. RFID (Radio-Frequency Identification) badge readers are commonly used for secure access control in facilities. These readers can authenticate individuals based on RFID badges or cards, providing a secure means of access to network equipment.

  While options A (Full-size body scanners) and B (Iris scanner) are more associated with physical security measures for access to the facility, option D (Smart deadbolt) is related to securing physical doors and may not be directly tied to securing the network infrastructure in the IDF.

• Question 182:

  Which of the following are environmental factors that should be considered when installing equipment in a building? (Choose two.)

  A. Fire suppression system

  B. UPS location

  C. Humidity control

  D. Power load

  E. Floor construction type

  F. Proximity to nearest MDF

  Correct Answer: AC

  Fire suppression system: Ensures that the facility has adequate measures in place to suppress or extinguish fires in case of emergencies, protecting both equipment and personnel. Humidity control: Maintaining proper humidity levels is crucial for the optimal performance and longevity of electronic equipment. Excessive humidity can lead to condensation and potential damage.

• Question 183:

  Which of the following cloud deployment models involves servers that are hosted at a company's property and are only used by that company?

  A. Public

  B. Private

  C. Hybrid

  D. Community

  Correct Answer: B

  In the context of cloud computing deployment models:

  -

  Public: Resources are owned and operated by a third-party cloud service provider and are made available to the general public.

  -

  Private: Resources are used exclusively by a single organization. The servers can be hosted on-premises (as in the case of a private cloud) or by a third-party provider exclusively for that organization.

  -

  Hybrid: Involves a combination of both public and private cloud resources.

  -

  Community: Resources are shared by multiple organizations with similar concerns, needs, or missions.

• Question 184:

  A technician needs to find the MAC address of a connecting router. Which of the following commands should the technician use?

  A. arp

  B. traceroute

  C. nslookup

  D. ping

  Correct Answer: A

  The Address Resolution Protocol (ARP) is used to map a known IP address to a MAC address on a local network. If a technician needs to find the MAC address of a connecting router, they can use the ARP command.

• Question 185:

  A technician needs to set up a wireless connection that utilizes MIMO on non-overlapping channels. Which of the following would be the best choice?

  A. 802.11a

  B. 802.11b

  C. 802.11g

  D. 802.11n

  Correct Answer: D

  Multiple Input Multiple Output (MIMO) technology is most effectively utilized by the 802.11n wireless standard. MIMO involves the use of multiple antennas at both the transmitter and receiver to improve communication performance. It allows for increased data throughput and improved wireless coverage.

• Question 186:

  A network engineer designed and implemented a new office space with the following characteristics:

  

  One month after the office space was implemented, users began reporting dropped signals when entering another room and overall poor connections to the 5GHz network. Which of the following should the engineer do to best resolve the issue?

  A. Use non-overlapping channels.

  B. Reconfigure the network to support 2.4GHz

  C. Upgrade to WPA3.

  D. Change to directional antennas.

  Correct Answer: B

• Question 187:

  A network technician is troubleshooting internet connectivity issues with users in a subnet. From a host, the technician runs tcpdump and then attempts to navigate to a website using a web browser. The technician receives the following output:

  

  Afterward, the browser displays an error. Which of the following explains this issue?

  A. A routing loop is within the network.

  B. The host is configured with incorrect DNS settings.

  C. A broadcast storm is occurring on the subnet.

  D. The host is missing a route to the website.

  Correct Answer: D

• Question 188:

  A network engineer turned on logging to assist with troubleshooting a suspected configuration issue. Which of the following would provide the network engineer with the most informative log information?

  A. FATAL

  B. ERROR

  C. DEBUG

  D. WARN

  Correct Answer: C

  In logging levels, DEBUG provides the most detailed and informative information for troubleshooting. Different logging levels serve various purposes:

  -

  FATAL: Indicates a very severe error that will lead to a program's termination.

  -

  ERROR: Indicates a less severe error, but still a problem that requires attention.

  -

  WARN (Warning): Indicates a potential issue that does not necessarily cause an error but should be noted.

  -

  DEBUG: Provides detailed information about the program's operation for debugging purposes. DEBUG logs are typically used during troubleshooting to gain insights into the system's behavior.

  Therefore, if the network engineer is troubleshooting a suspected configuration issue, enabling DEBUG-level logging would provide the most detailed information for analysis.

• Question 189:

  Which of the following topologies requires me MOST connections when designing a network?

  A. Mesh

  B. Star

  C. Bus

  D. Ring

  Correct Answer: A

• Question 190:

  Which of the following fouling protocols is generally used by major ISPs for handing largescale internet traffic?

  A. RIP

  B. EIGRP

  C. OSPF

  D. BGP

  Correct Answer: D
