CompTIA N10-008 Online Questions & Answers

• Question 821:

  An organization has a security requirement that all network connections can be traced back to a user. A network administrator needs to identify a solution to implement on the wireless network. Which of the following is the best solution?

  A. Implementing enterprise authentication
  B. Requiring the use of PSKs
  C. Configuring a captive portal for users
  D. Enforcing wired equivalent protection
  A. Implementing enterprise authentication

  ---

  Explanation/Reference:

  Enterprise authentication is a method of securing wireless networks that uses an external authentication server, such as RADIUS, to verify the identity of users and devices. Enterprise authentication can provide user traceability by logging the

  network connections and activities of each authenticated user. This can help the organization meet its security requirement and comply with any regulations or policies that mandate user accountability12.

• Question 822:

  A customer needs to distribute Ethernet to multiple computers in an office. The customer would like to use non-proprietary standards. Which of the following blocks does the technician need to install?

  A. 110
  B. 66
  C. Bix
  D. Krone
  A. 110

  ---

  Explanation/Reference:

  A 110 block is a type of punch-down block that is used to distribute Ethernet to multiple computers in an office. A punch-down block is a device that connects one group of wires to another group of wires by using a special tool that pushes the wires into slots on the block. A 110 block is a non-proprietary standard that supports up to Category 6 cabling and can be used for voice or data applications.

• Question 823:

  A technician is connecting multiple switches to create a large network for a new office. The switches are unmanaged Layer 2 switches with multiple connections between each pair. The network is experiencing an extreme amount of latency. Which of the following is MOST likely occurring?

  A. Ethernet collisions
  B. A DDoS attack
  C. A broadcast storm
  D. Routing loops
  C. A broadcast storm

  ---

  Explanation/Reference:

  Broadcast storm as the switches are unmanaged.

• Question 824:

  Which of the following is used to require network devices to authenticate before gaining access to a LAN?

  A. 802.1Q
  B. 802.1X
  C. 802.11ax
  D. 802.3af
  B. 802.1X

  ---

  Explanation/Reference:

  802.1X: IEEE 802.1X is a network access control standard that provides an authentication framework for controlling access to LANs or WLANs (Wireless Local Area Networks). It ensures that only authorized devices and users are granted access to the network. 802.1X is commonly used in Ethernet and Wi-Fi networks to enforce user-based authentication and security policies before allowing network access.

• Question 825:

  Which of the following is a characteristic of the application layer?

  A. It relies upon other layers for packet delivery.
  B. It checks independently for packet loss.
  C. It encrypts data in transit.
  D. It performs address translation.
  A. It relies upon other layers for packet delivery.

• Question 826:

  A network engineer performed a detailed network analysis. The engineer has decided to update the STP port cost in order to optimize the network. Which of the following processes should the engineer use to gain approval for the network optimization?

  A. Business continuity
  B. Disaster recovery
  C. Incident response
  D. Change management
  D. Change management

• Question 827:

  Which of the following best describes what an organization would use port address translation for?

  A. VLANs on the perimeter
  B. Public address on the perimeter router
  C. Non-routable address on the perimeter router
  D. Servers on the perimeter
  B. Public address on the perimeter router

  ---

  Explanation/Reference:

  The best answer is B. Public address on the perimeter router. Port address translation (PAT) is a function that allows multiple users within a private network to make use of a minimal number of IP addresses. Its basic function is to share a single IP public address between multiple clients who need to use the Internet publicly. It is an extension of network address translation (NAT)1. PAT works by creating dynamic NAT mapping, in which a global (public) IP address and a unique port number are selected. The router keeps a NAT table entry for every unique combination of the private IP address and port, with translation to the global address and a unique port number2. Therefore, an organization would use PAT for having a public address on the perimeter router, which can be shared by many hosts on the private network using different port numbers. This can reduce the bandwidth consumption and cost of the organization's internet connection, as well as provide some security benefits by hiding the internal network structure3. The other options are not correct because: VLANs on the perimeter are not related to PAT, as they are used to segment the network into logical groups based on different criteria, such as function, security, or performance4. Non-routable address on the perimeter router would not allow the organization to access the Internet or the cloud, as non-routable addresses are not valid on the public network and cannot be translated by PAT5. Servers on the perimeter are not a reason to use PAT, as servers usually have static IP addresses and do not need to share a public address with other hosts. Servers on the perimeter may use NAT, but not PAT, to map their private IP addresses to a public IP address2.

• Question 828:

  A network technician added a new workstation to the network and needs to make a custom, shielded cable that is 492ft (150m) with both ends wired to TIA/EIA-568A standards. The workstation is not establishing a link to the switchport. Which of the following is the cause of the issue?

  A. Cable shielding
  B. Attenuation
  C. Incorrect pinout
  D. Near-end crosstalk
