CompTIA N10-008 Online Questions & Answers

• Question 541:

  A user recently made changes to a PC that caused it to be unable to access websites by both FQDN and IP Local resources, such as the file server remain accessible. Which of the following settings did the user MOST likely misconfigure?

  A. Static IP
  B. Default gateway
  C. DNS entries
  D. Local host file
  B. Default gateway

  ---

  Explanation/Reference:

  The default gateway is the setting that the user most likely misconfigured on the PC that caused it to be unable to access websites by both FQDN and IP. The default gateway is a device, usually a router or a firewall, that connects a local network to other networks such as the Internet. It acts as an intermediary between devices on different networks and forwards packets based on their destination IP addresses. If the default gateway is not configured correctly on a PC, it will not be able to communicate with devices outside its local network, such as web servers or DNS servers.

• Question 542:

  Which of the following policies outlines the software and hardware requirements for using personally owned devices to conduct business?

  A. DLP
  B. AUP
  C. BYOD
  D. NDA
  C. BYOD

  ---

  Explanation/Reference:

  The policy that outlines the software and hardware requirements for using personally owned devices to conduct business is BYOD (Bring Your Own Device). BYOD is a practice that allows employees to use their own devices, such as laptops, tablets, or smartphones, to access corporate resources and applications. BYOD can offer benefits such as increased productivity, flexibility, and satisfaction for employees, as well as reduced costs for employers. However, BYOD also poses challenges and risks, such as security, compatibility, and support issues. Therefore, a BYOD policy is needed to define the rules and expectations for using personal devices in a business environment. A BYOD policy typically covers topics such as device eligibility, security requirements, acceptable use, data ownership, privacy, and liability.

• Question 543:

  A technician monitors a switch interface and notices it is not forwarding frames on a trunked port. However, the cable and interfaces are in working order. Which of the following is MOST likely the cause of the issue?

  A. STP policy
  B. Flow control
  C. 802.1Q configuration
  D. Frame size
  C. 802.1Q configuration

• Question 544:

  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
  C. DEBUG

  ---

  Explanation/Reference:

  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 545:

  A user reports that the internet seems slow on a workstation, but no other users have reported any issues. The server team confirms the servers are functioning normally. A technician suspects something specific to the user's computer is overutilizing bandwidth. Which of the following commands should the technician use to further investigate the issue?

  A. nmap
  B. tcpdump
  C. netstat
  D. nslookup
  C. netstat

• Question 546:

  Which of the following concepts would MOST likely be used to identify individual pieces of hardware throughout their life cycle?

  A. Geofencing
  B. Smart locker
  C. Chain of custody
  D. Asset tagging
  D. Asset tagging

• Question 547:

  Which of the following layers of the OSI model is responsible for end-to-end encryption?

  A. Presentation
  B. Application
  C. Session
  D. Transport
  A. Presentation

  ---

  Explanation/Reference:

  The Presentation layer of the OSI model is primarily responsible for formatting, encrypting, and compressing data in a way that the Application layer can understand. Encryption, as a part of data formatting, is often implemented in this layer to ensure end-to-end secure communication between applications.

  While encryption can also be implemented at other layers of the OSI model, such as the Application layer (for application-specific encryption) and the Transport layer (for transport-level encryption such as SSL/TLS), the Presentation layer specifically deals with the syntax and semantics of the data to be exchanged and is where data encryption/decryption often takes place, allowing for secure communication between applications.

• Question 548:

  A company is implementing a secure remote access solution for multiple employees. Which of the following should the company use?

  A. Remote desktop connection
  B. Virtual desktop
  C. Site-to-site VPN
  D. Client-to-site VPN
  D. Client-to-site VPN

• Question 549:

  A network administrator installed a WAP to extend the network. However, the company wants to contain the signal so it does not extend beyond the company's parking structure. Which of the following solutions would work BEST?

  A. Create MAC filtering.
  B. Change the channel.
  C. Change the encryption.
  D. Install a directional antenna.
  D. Install a directional antenna.
