CompTIA N10-008 Online Questions & Answers

• Question 371:

  A network administrator needs to provide remote clients with access to an internal web application. Which of the following methods provides the HIGHEST flexibility and compatibility while encrypting only the connection to the web application?

  A. Clientless VPN
  B. Virtual desktop
  C. Virtual network computing
  D. mGRE tunnel
  A. Clientless VPN

  ---

  Explanation/Reference:

  A clientless VPN (Virtual Private Network) provides the highest flexibility and compatibility for remote clients to access an internal web application because it allows remote users to connect to the internal network using a web browser, without the need to install any additional software or configurations on their device. This allows the remote users to access the web application securely over an encrypted connection, while also providing a high level of compatibility with different device types and operating systems.

• Question 372:

  An administrator is preparing an organization for a potential disaster. The administrator configures the network switches and turns off the equipment in a data center. Which of the following is this scenario an example of?

  A. Warm site
  B. Cold site
  C. Cloud site
  D. Hot site
  A. Warm site

• Question 373:

  A network administrator is looking for a solution to extend Layer 2 capabilities and replicate backups between sites. Which of the following is the best solution?

  A. Security Service Edge
  B. Data center interconnect
  C. Infrastructure as code
  D. Zero trust architecture
  B. Data center interconnect

  ---

  Explanation/Reference:

  Data center interconnect (DCI) is a solution that allows Layer 2 connectivity and data replication between geographically dispersed data centers. DCI can be implemented using various technologies, such as optical networks, MPLS, VPNs, or Ethernet. DCI can provide benefits such as improved disaster recovery, load balancing, resource pooling, and cloud services.

• Question 374:

  A network engineer is investigating reports of poor network performance. Upon reviewing a report, the engineer finds that jitter at the office is greater than 10ms on the only WAN connection available. Which of the following would be MOST affected by this statistic?

  A. A VoIP sales call with a customer
  B. An in-office video call with a coworker
  C. Routing table from the ISP
  D. Firewall CPU processing time
  A. A VoIP sales call with a customer

  ---

  Explanation/Reference:

  keyword WAN , since the voip call is with a customer, it is out of office using the WAN

• Question 375:

  Which of the following routing protocols uses an autonomous system number?

  A. IS-IS
  B. EIGRP
  C. OSPF
  D. BGP
  D. BGP

  ---

  Explanation/Reference:

  An autonomous system (AS) is a collection of IP networks and routers under the control of a single entity that presents a common routing policy to the internet. BGP (Border Gateway Protocol) is the routing protocol commonly used to exchange routing and reachability information between autonomous systems on the internet. BGP uses an autonomous system number (ASN) to uniquely identify each autonomous system.

• Question 376:

  A hydroelectric company wants to manage sensors at a dam remotely. The control station at this dam is several miles off the main road in a densely forested area. Which of the following should the company implement to connect remotely to the sensors?

  A. Cable broadband
  B. DSL Internet
  C. Cellular modem
  D. ISDN Internet
  C. Cellular modem

• Question 377:

  At the destination host, which of the following OSI model layers will discard a segment with a bad checksum in the UDP header?

  A. Network
  B. Data link
  C. Transport
  D. Session
  C. Transport

  ---

  Explanation/Reference:

  In the OSI model, the transport layer is responsible for providing end-to-end communication services to the upper layers. One of the key responsibilities of the transport layer is to ensure the integrity of data being transmitted.

  In the case of a UDP segment, the transport layer at the destination host will check the checksum in the UDP header. If the checksum is incorrect or invalid, the transport layer will discard the segment as it indicates that the data has been corrupted during transmission.

• Question 378:

  A company streams video to multiple devices across a campus. When this happens, several users report a degradation of network performance. Which of the following would MOST likely address this issue?

  A. Enable IGMP snooping on the switches.
  B. Implement another DHCP server.
  C. Reconfigure port tagging for the video traffic.
  D. Change the SSID of the APs
  A. Enable IGMP snooping on the switches.

  ---

  Explanation/Reference:

  IGMP snooping stands for Internet Group Management Protocol snooping. It is a feature commonly found in network switches that helps optimize multicast traffic distribution. In this scenario, when video streaming is causing a degradation of network performance, enabling IGMP snooping on the switches would be the most likely solution.

  Multicast traffic, such as video streams, can flood the network if not properly managed. IGMP snooping allows switches to intelligently forward multicast traffic only to the ports where interested receivers are located. By enabling IGMP snooping, the switches can efficiently deliver the video streams to the devices requesting them, reducing unnecessary network congestion and improving overall network performance.

  Therefore, enabling IGMP snooping on the switches is the most appropriate solution to address the reported degradation of network performance during video streaming.

• Question 379:

  A technician needs to map the path of a PC to the router. Which of the following tools should the technician use to accomplish this task?

  A. traceroute
  B. ping
  C. ifconfig
  D. netstat
  A. traceroute

• Question 380:

  A network technician is configuring a new web server at the company office. The network manager has instructed the technician to implement it in such a way so it is isolated from the local network and still able to be reached from an external network. Which of the following BEST describes where the technician should set up the new server?

  A. Private VLAN
  B. IDF
  C. DMZ
  D. Native VLAN
  C. DMZ
