CompTIA N10-008 Online Questions & Answers

• Question 211:

  A user reports a weak signal when walking 20ft (61 m) away from the WAP in one direction, but a strong signal when walking 20ft in the opposite direction

  The technician has reviewed the configuration and confirmed the channel type is correct

  There is no jitter or latency on the connection.

  Which of the following would be the MOST likely cause of the issue?

  A. Antenna type
  B. Power levels
  C. Frequency
  D. Encryption type
  A. Antenna type

  ---

  Explanation/Reference:

  The antenna type affects the signal strength and coverage of a WAP. Different types of antennas have different radiation patterns and gain, which determine how far and wide the signal can reach. If the user experiences a weak signal in one direction but a strong signal in the opposite direction, it could mean that the antenna type is not suitable for the desired coverage area. The technician should consider changing the antenna type to one that has a more balanced or directional radiation pattern.

• Question 212:

  Which of the following is used to provide networking capability for VMs at Layer 2 of the OSI model?

  A. VPN
  B. VRRP
  C. vSwitch
  D. VIP
  C. vSwitch

  ---

  Explanation/Reference:

  A vSwitch (virtual switch) is a software-based switch that provides networking capability for VMs (virtual machines) at Layer 2 of the OSI model. It connects the VMs to each other or to external networks using virtual NICs (network interface cards). A VPN (virtual private network) is a technology that creates a secure tunnel over a public network for remote access or site-to-site connectivity. VRRP (Virtual Router Redundancy Protocol) is a protocol that provides high availability for routers by creating a virtual router with multiple physical routers. A VIP (virtual IP) is an IP address that can be shared by multiple servers or devices for load balancing or failover purposes.

• Question 213:

  Network traffic is being compromised by DNS poisoning every time a company's router is connected to the internet. The network team detects a non-authorized DNS server being assigned to the network clients and remediates the incident by setting a trusted DNS server, but the issue occurs again after internet exposure. Which of the following best practices should be implemented on the router?

  A. Change the device's default password.
  B. Disable router advertisement guard.
  C. Activate control plane policing.
  D. Disable unneeded network services.
  A. Change the device's default password.

• Question 214:

  Which of the following BEST describes hosting several businesses on the same physical infrastructure?

  A. Hybrid
  B. Elasticity
  C. laaS
  D. Multitenancy
  D. Multitenancy

  ---

  Explanation/Reference:

  Multitenancy, which is when several different cloud customers are accessing the same computing resources, such as when several different companies are storing data on the same physical server. https://www.cloudflare.com/learning/cloud/what-is-multitenancy

• Question 215:

  An organization with one core and five distribution switches is transitioning from a star to a full-mesh topology. Which of the following is the number of additional network connections needed?

  A. 5
  B. 7
  C. 10
  D. 15
  C. 10

  ---

  Explanation/Reference:

  10 additional network connections are needed to transition from a star to a full-mesh topology. A star topology is a network topology where each device is connected to a central device, such as a switch or a hub. A full-mesh topology is a network topology where each device is directly connected to every other device. The number of connections needed for a full-mesh topology can be calculated by the formula n(n-1)/2, where n is the number of devices. In this case, there are six devices (one core and five distribution switches), so the number of connections needed for a full-mesh topology is 6(6-1)/2 = 15. Since there are already five connections in the star topology (one from each distribution switch to the core switch), the number of additional connections needed is 15 - 5 = 10.

• Question 216:

  A network administrator is designing a new network for a company that has frequent power spikes. The company wants to ensure that employees can keep working and the server will remain operational. Which of the following is the best solution for the administrator to recommend?

  A. Generator
  B. Cold site
  C. Redundant power supplies
  D. Uninterruptible power supply
  D. Uninterruptible power supply

  ---

  Explanation/Reference:

  To protect against power spikes and ensure continuity of operations during power outages, a UPS (Uninterruptible Power Supply) is the best solution. A UPS provides a temporary power source during electrical failures, allowing systems to shut down gracefully or continue operating for a short duration until power is restored or a generator takes over.

  While a generator (option A) is a solution for longer-term power outages, a UPS is typically used for short-term disruptions and provides immediate protection against power spikes and brief outages.

• Question 217:

  Which of the following use cases would justify the deployment of an mGRE hub-and-spoke topology?

  A. An increase in network securing using encryption and packet encapsulation
  B. A network expansion caused by an increase in the number of branch locations to the headquarters
  C. A mandatory requirement to increase the deployment of an SDWAN network.
  D. An improvement in network efficiency by increasing the useful packet payload.
  B. A network expansion caused by an increase in the number of branch locations to the headquarters

  ---

  Explanation/Reference:

  A network expansion caused by an increase in the number of branch locations to the headquarters

• Question 218:

  There are two managed legacy switches running that cannot be replaced or upgraded. These switches do not support cryptographic functions, but they are password protected. Which of the following should a network administrator configure to BEST prevent unauthorized access?

  A. Enable a management access list
  B. Disable access to unnecessary services.
  C. Configure a stronger password for access
  D. Disable access to remote management
  E. Use an out-of-band access method.
  A. Enable a management access list

  ---

  Explanation/Reference:

  Using an out-of-band access method is the best way to prevent unauthorized access to the legacy switches that do not support cryptographic functions. Out-of-band access is a method of accessing a network device through a dedicated channel that is separate from the main network traffic. Out-of-band access can use physical connections such as serial console ports or dial-up modems, or logical connections such as VPNs or firewalls. Out-of-band access provides more security and reliability than in-band access, which uses the same network as the data traffic and may be vulnerable to attacks or failures.

• Question 219:

  A malicious user sent double-tagged frames on an 802.1Q-enabled port and immediately gained access to additional network resources. Which of the following attacks did the malicious user successfully execute?

  A. Evil twin
  B. Man-in-the-middle
  C. DNS poisoning
  D. VLAN hopping
  D. VLAN hopping

• Question 220:

  A network engineer is configuring new switches. Some of the trunk ports are in a blocking state. Which of the following should the network engineer reconfigure?

  A. STP
  B. Port mirroring
  C. Flow control
  D. LACP
  A. STP

  ---

  Explanation/Reference:

  STP (Spanning Tree Protocol) is a protocol that prevents loops in a network by placing some of the switch ports in different states, such as blocking, listening, learning, forwarding, or disabled. A port in the blocking state does not forward frames or participate in frame forwarding. A network engineer can reconfigure STP to change the port states and avoid blocking ports that are needed for trunking.
