CompTIA N10-008 Online Questions & Answers

• Question 491:

  An engineer recently installed a new distribution switch and connected two servers provisioned with the following IPs: 192.168.17.20 and 192.168.17.30.

  The servers cannot connect to the internet, but they can reach themselves. The engineer observes that the distribution switch has the following setup:

  interface VLAN 100 IP address 192.168.17.5 255.255.255.0

  The engineer is able to reach the core router 192.168.17.1 from the distribution switch. Which of the following is the most likely cause of this issue?

  A. A routing loop has occurred.
  B. The subnet mask is incorrect.
  C. The servers are not configured with default gateway.
  D. There is an improper Layer 1 connection between the router and the ISP modem.
  C. The servers are not configured with default gateway.

  ---

  Explanation/Reference:

  The servers can communicate with each other but not the internet, indicating local network connectivity is fine. The distribution switch's VLAN and IP configuration are correct, and the engineer can reach the core router, suggesting the issue is not with the switch or the router. The most likely cause is that the servers do not have a default gateway configured, which is necessary for traffic to leave the local network and reach the internet.

• Question 492:

  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

• Question 493:

  A network administrator is installing a wireless network at a client's office. Which of the following IEEE 802.11 standards would be BEST to use for multiple simultaneous client access?

  A. CDMA
  B. CSMA/CD
  C. CSMA/CA
  D. GSM
  C. CSMA/CA

  ---

  Explanation/Reference:

  CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) would be the best to use for multiple simultaneous client access. CSMA/CA is the protocol used by the IEEE 802.11 standard for wireless networks. It allows multiple wireless clients to access the network simultaneously, by using carrier sensing to avoid collisions and reduce the chance of data corruption. This makes CSMA/CA ideal for wireless networks with many clients, as it provides efficient and reliable access for all clients.

• Question 494:

  A local service provider connected 20 schools in a large city with a fiber-optic switched network. Which of the following network types did the provider set up?

  A. LAN
  B. MAN
  C. CAN
  D. WAN
  B. MAN

  ---

  Explanation/Reference:

  MAN stands for Metropolitan Area Network, and it is a type of network that covers a large geographic area, such as a city or a county. MANs are often used to connect multiple LANs (Local Area Networks) within a region, such as schools,

  offices, or government buildings. MANs typically use high-speed and high-capacity transmission media, such as fiber-optic cables, to provide fast and reliable data communication. MANs can also provide access to WANs (Wide Area

  Networks), such as the Internet, or other services, such as cable TV or VoIP.

  The other options are not correct because they are not the type of network that covers a large city. They are:

  LAN. LAN stands for Local Area Network, and it is a type of network that covers a small geographic area, such as a home, an office, or a building. LANs are often used to connect multiple devices, such as computers, printers, or phones,

  within a single network. LANs typically use low-cost and low-capacity transmission media, such as twisted-pair cables, to provide data communication. LANs can also provide access to other networks, such as MANs or WANs, through routers

  or gateways.

  CAN. CAN stands for Campus Area Network, and it is a type of network that covers a moderate geographic area, such as a university, a hospital, or a military base. CANs are often used to connect multiple LANs within a campus, such as

  different departments, buildings, or facilities. CANs typically use medium-cost and medium-capacity transmission media, such as coaxial cables, to provide data communication. CANs can also provide access to other networks, such as MANs

  or WANs, through routers or gateways.

  WAN. WAN stands for Wide Area Network, and it is a type of network that covers a very large geographic area, such as a country, a continent, or the world. WANs are often used to connect multiple MANs or LANs across different regions,

  such as different cities, states, or countries. WANs typically use high-cost and high- capacity transmission media, such as satellite links, to provide data communication. WANs can also provide access to various services, such as the Internet,

  email, or VPN.

• Question 495:

  A technician is equipped with a tablet, a smartphone, and a laptop to troubleshoot a switch with the help of support over the phone. However, the technician is having issues interconnecting all these tools in troubleshooting the switch. Which of the following should the technician use to gain connectivity?

  A. PAN
  B. WAN
  C. LAN
  D. MAN
  A. PAN

  ---

  Explanation/Reference:

  A PAN stands for Personal Area Network and it is a type of network that connects devices within a small range, such as a few meters. A PAN can use wireless technologies such as Bluetooth or Wi-Fi to interconnect devices such as tablets,

  smartphones, and laptops. A technician can use a PAN to gain connectivity among these tools and troubleshoot the switch.

• Question 496:

  Which of the following topologies requires me MOST connections when designing a network?

  A. Mesh
  B. Star
  C. Bus
  D. Ring
  A. Mesh

• Question 497:

  A network administrator is concerned about a rainbow table being used to help access network resources. Which of the following must be addressed to reduce the likelihood of a rainbow table being effective?

  A. Password policy
  B. Remote access policy
  C. Acceptable use policy
  D. Data loss prevention policy
  A. Password policy

  ---

  Explanation/Reference:

  Rainbow tables are tables of reversed hashes used to crack password hashes. Computer systems requiring passwords typically store the passwords as a hash value of the user's password. When a computer user enters a password, the system hashes the password and compares it to the stored hash.

• Question 498:

  Which of the following is the physical topology for an Ethernet LAN?

  A. Bus
  B. Ring
  C. Mesh
  D. Star
  D. Star

  ---

  Explanation/Reference:

  In a Star topology, all devices on the LAN are connected to a central hub or switch. The hub or switch acts as a central point for data transmission and reception. Each device on the LAN has a dedicated connection to the hub or switch, and data is transmitted between devices through the hub or switch.

• Question 499:

  An IT technician needs to increase bandwidth to a server. The server has multiple gigabit ports. Which of the following can be used to accomplish this without replacing hardware?

  A. STP
  B. 802.1Q
  C. Duplex
  D. LACP
  D. LACP

  ---

  Explanation/Reference:

  LACP stands for Link Aggregation Control Protocol and is a protocol that allows multiple physical ports to be combined into a single logical port. This can increase bandwidth, redundancy, and load balancing for a server. LACP is part of the IEEE 802.3ad standard for link aggregation. STP stands for Spanning Tree Protocol and is a protocol that prevents loops in a network by blocking redundant links. 802.1Q is a standard for VLAN (Virtual Local Area Network) tagging, which allows multiple logical networks to share the same physical infrastructure. Duplex is a mode of communication that determines how data is transmitted and received on a link. Full duplex allows simultaneous transmission and reception, while half duplex allows only one direction at a time.
