CompTIA N10-008 Online Questions & Answers

• Question 181:

  Which of the following BEST describes a network appliance that warns of unapproved devices that are accessing the network?

  A. Firewall
  B. AP
  C. Proxy server
  D. IDS
  D. IDS

  ---

  Explanation/Reference:

  -

  IDS stands for Intrusion Detection System. It is a type of security software designed to detect unauthorised access to, or attacks on, a computer network. IDS works by monitoring network traffic and looking for signs of malicious activity, such as suspicious network packets, unusual traffic patterns, or attempts to exploit vulnerabilities in the network or in specific systems.

  -

  The goal of IDS is to provide early warning of potential security threats and to help prevent attacks before they can cause damage.

• Question 182:

  A user is required to log in to a main web application, which then grants the user access to all other programs needed to complete job-related tasks. Which of the following authentication methods does this setup describe?

  A. SSO
  B. RADIUS
  C. TACACS+
  D. Multifactor authentication
  E. 802.1X
  A. SSO

  ---

  Explanation/Reference:

  The scenario you've described, where a user logs in to a main web application that grants access to other programs needed for job-related tasks, is typically implemented using a Single Sign-On (SSO) solution.

  Single Sign-On (SSO) allows a user to authenticate once with a central identity provider (such as the main web application) and then gain access to multiple other applications without needing to provide separate credentials for each application. This streamlines the authentication process, enhances user experience, and improves security by centralizing user authentication and access control.

• Question 183:

  A network administrator receives a call about a network printer that is not working for a workstation. The network administrator verifies the printer is turned on. Given the following information:

  Router's gateway IP: 10.0.0.1/25 Device: Printer

  

  Device: Workstation

  

  Which of the following should the administrator change to remediate this issue? (Choose two.)

  A. The subnet on the router
  B. The IP address on the printer
  C. The subnet on the printer
  D. The IP address on the router
  E. The subnet on the workstation
  F. The IP address on the workstation
  B. The IP address on the printer
  E. The subnet on the workstation

• Question 184:

  Which of the following would be BEST to use to detect a MAC spoofing attack?

  A. Internet Control Message Protocol
  B. Reverse Address Resolution Protocol
  C. Dynamic Host Configuration Protocol
  D. Internet Message Access Protocol
  B. Reverse Address Resolution Protocol

  ---

  Explanation/Reference:

  Reverse Address Resolution Protocol . Can be used to ask what a machine's IP address is based on it's MAC address. If the adress has been spoofed it will obviously show a different IP than the one it is expecting to see

• Question 185:

  A network technician is attempting to resolve an issue for two users. The users unplugged and moved their laptops to a different cubicle to work together. The NIC LED Is lit on both laptops, but the users are not able to access the network resources. Which of the following is MOST likely preventing access?

  A. Port security
  B. Auto-MDIX
  C. BDPU guard
  D. DHCP snooping
  A. Port security

• Question 186:

  Which of the following is the IEEE link cost for a Fast Ethernet interface in STP calculations?

  A. 2
  B. 4
  C. 19
  D. 100
  C. 19

  ---

  Explanation/Reference:

  Link Speed Cost Value 10 Gbps 2 1 Gbps 4 100 Mbps 19 10 Mbps 100

• Question 187:

  A network administrator wants to implement an authentication process for temporary access to an organization's network. Which of the following technologies would facilitate this process?

  A. Captive portal
  B. Enterprise authentication
  C. Ad hoc network
  D. WPA3
  A. Captive portal

  ---

  Explanation/Reference:

  A captive portal is a technology that facilitates the authentication process for temporary access to a network. It is commonly used in public Wi-Fi hotspots, hotels, airports, and other environments where temporary network access is provided. When users connect to the network, they are redirected to a captive portal page where they must authenticate or agree to terms and conditions before gaining access to the internet or other network resources.

• Question 188:

  The network engineer receives a new router to use for WAN connectivity. Which of the following best describes the layer the network engineer should connect the new router to?

  A. Core
  B. Leaf
  C. Distribution
  D. Access
  C. Distribution

  ---

  Explanation/Reference:

  The distribution layer is the layer that connects the access layer to the core layer in a hierarchical network design. The distribution layer is responsible for routing, filtering, and policy enforcement between the LAN and the WAN. A router is a layer 3 device that can perform these functions and connect to different WAN technologies.

• Question 189:

  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.
  C. The camera requires Cat 7 cabling.

• Question 190:

  During the troubleshooting of an E1 line, the point-to-point link on the core router was accidentally unplugged and left unconnected for several hours. However, the network management team was not notified. Which of the following could have been configured to allow early detection and possible resolution of the issue?

  A. Traps
  B. MIB
  C. OID
  D. Baselines
  A. Traps

  ---

  Explanation/Reference:

  Traps are unsolicited messages sent by network devices to a network management system (NMS) when an event or a change in status occurs. Traps can help notify the network management team of any issues or problems on the network, such as a link failure or a device reboot. Traps can also trigger actions or alerts on the NMS, such as sending an email or logging the event. MIB stands for Management Information Base and is a database of information that can be accessed and managed by an NMS using SNMP (Simple Network Management Protocol). OID stands for Object Identifier and is a unique name that identifies a specific variable in the MIB. Baselines are measurements of normal network performance and behavior that can be used for comparison and analysis.
