CompTIA N10-008 Online Questions & Answers

• Question 701:

  A technician is deploying a low-density wireless network and is contending with multiple types of building materials. Which of the following wireless frequencies would allow for the LEAST signal attenuation?

  A. 2.4GHz
  B. 5GHz
  C. 850MHz
  D. 900MHZ
  A. 2.4GHz

  ---

  Explanation/Reference:

  2.4GHz is the wireless frequency that would allow for the least signal attenuation when deploying a low-density wireless network with multiple types of building materials. Signal attenuation is the loss of signal strength or quality as it travels through a medium or over a distance. Signal attenuation can be affected by various factors such as distance, interference, reflection, refraction, diffraction, scattering, or absorption. Generally, lower frequencies have less signal attenuation than higher frequencies because they can penetrate obstacles better and travel farther. Therefore, 2.4GHz would have less signal attenuation than 5GHz, 850MHz, or 900MHz.

• Question 702:

  A network administrator is investigating an issue with VoIP calls that are not establishing properly. After troubleshooting, the administrator is able to determine the SIP responses are not being received by the gateway. Which of the following did the administrator use to determine this information?

  A. netstat
  B. A spectrum analyzer
  C. tracert
  D. A packet analyzer
  D. A packet analyzer

• Question 703:

  During the security audit of a financial firm the Chief Executive Officer (CEO) questions why there are three employees who perform very distinct functions on the server. There is an administrator for creating users another for assigning the

  users lo groups and a third who is the only administrator to perform file rights assignment.

  Which of the following mitigation techniques is being applied'

  A. Privileged user accounts
  B. Role separation
  C. Container administration
  D. Job rotation
  B. Role separation

  ---

  Explanation/Reference:

  Role separation is a security principle that involves dividing the tasks and privileges for a specific business process among multiple users. This reduces the risk of fraud and errors, as no one user has complete control over the process. In the scenario, there are three employees who perform very distinct functions on the server, which is an example of role separation.

• Question 704:

  A public, wireless ISP mounts its access points on top of traffic signal poles. Fiber-optic cables are installed from a fiber switch through the ground and up the pole to a fiber-copper media converter, and then connected to the AP. In one location, the switchport is showing sporadic link loss to the attached AP. A similar link loss is not seen at the AP interface. The fiber-optic cable is moved to another unused switchport with a similar result.

  Which of the following steps should the assigned technician complete NEXT?

  A. Disable and enable the switchport.
  B. Clean the fiber-optic cable ends.
  C. Replace the media converter.
  D. Replace the copper patch cord.
  B. Clean the fiber-optic cable ends.

  ---

  Explanation/Reference:

  Fiber-optic cables are cables that use light signals to transmit data over long distances at high speeds. Fiber-optic cables are sensitive to dirt, dust, moisture, or other contaminants that can interfere with the light signals and cause link loss or signal degradation. To troubleshoot link loss issues with fiber-optic cables, one of the steps that should be completed next is to clean the fiber-optic cable ends with a lint-free cloth or a specialized cleaning tool. Cleaning the fiber-optic cable ends can remove any dirt or debris that may be blocking or reflecting the light signals and restore the link quality.

• Question 705:

  An IT organization needs to optimize speeds for global content distribution and wants to reduce latency in high-density user locations. Which of the following technologies BEST meets the organization's requirements?

  A. Load balancing
  B. Geofencing
  C. Public cloud
  D. Content delivery network
  E. Infrastructure as a service
  D. Content delivery network

  ---

  Explanation/Reference:

  "A CDN is a distributed network of servers that store cached copies of website content in multiple geographic locations around the world. When a user requests content, the CDN selects the server closest to the user's location to deliver the content. This results in faster delivery times and lower latency.

  Load balancing is a technique used to distribute traffic across multiple servers to improve performance and reliability. While load balancing can help optimize speeds, it does not address the issue of reducing latency in high-density user locations."

• Question 706:

  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
  A. arp

  ---

  Explanation/Reference:

  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 707:

  A network administrator is preparing new switches that will be deployed to support a network extension project. The lead network engineer has already provided documentation to ensure the switches are set up properly. Which of the following did the engineer most likely provide?

  A. Physical network diagram
  B. Site survey reports
  C. Baseline configurations
  D. Logical network diagram
  D. Logical network diagram

• Question 708:

  Which of the following can be used to decrease latency during periods of high utilization of a firewall?

  A. Hot site
  B. NIC teaming
  C. HA pair
  D. VRRP
  C. HA pair

  ---

  Explanation/Reference:

  An HA pair is a group of two firewalls that are configured to work together to provide high availability and failover protection. If one firewall becomes unavailable, the other firewall can take over and continue providing network services. This can help to decrease latency during periods of high utilization because the workload is distributed across two firewalls rather than being handled by a single device.

• Question 709:

  A network administrator wants all outgoing traffic to the internet to flow through a single device for web content inspection. Which of the following devices is the most appropriate?

  A. VPN headend
  B. Router
  C. Proxy server
  D. Load balancer
  C. Proxy server

• Question 710:

  Which of the following provides redundancy on a file server to ensure the server is still connected to a LAN even in the event of a port failure on a switch?

  A. NIC teaming
  B. Load balancer
  C. RAID array
  D. PDUs
  A. NIC teaming
