CompTIA N10-008 Online Practice Questions and Exam Preparation

CompTIA N10-008 Online Questions & Answers

• Question 671:

  Which of the following is used to prioritize Internet usage per application and per user on the network?

  A. Bandwidth management
  B. Load balance routing
  C. Border Gateway Protocol
  D. Administrative distance
  A. Bandwidth management

  ---

  Explanation/Reference:

  Bandwidth management is the process of measuring and controlling the communications (traffic, packets) on a network link, to avoid filling the link to capacity or overfilling the link, which would result in network congestion and poor performance of the network.

• Question 672:

  An engineer notices some late collisions on a half-duplex link. The engineer verifies that the devices on both ends of the connection are configured for half duplex. Which of the following is the MOST likely cause of this issue?

  A. The link is improperly terminated
  B. One of the devices is misconfigured
  C. The cable length is excessive
  D. One of the devices has a hardware issue
  C. The cable length is excessive

  ---

  Explanation/Reference:

  In half-duplex mode, when two devices send data at the same time, a collision occurs, and both devices must wait for a random period before retransmitting the data. If the cable length is excessive, it may take longer for the collision signal to reach the far end of the cable, causing late collisions. To resolve the issue, the engineer should reduce the cable length or switch to full-duplex mode.

• Question 673:

  A network engineer is designing a new secure wireless network. The engineer has been given the following requirements:

  1 Must not use plaintext passwords

  2 Must be certificate based

  3. Must be vendor neutral

  Which of the following methods should the engineer select?

  A. TWP-RC4
  B. CCMP-AES
  C. EAP-TLS
  D. WPA2
  C. EAP-TLS

  ---

  Explanation/Reference:

  EAP-TLS is the method that should be selected to meet the requirements for designing a new secure wireless network. EAP-TLS (Extensible Authentication Protocol - Transport Layer Security) is an authentication protocol that uses X.509 digital certificates for both clients and servers. It provides strong security and mutual authentication by using TLS encryption and public key cryptography. It does not use plaintext passwords or shared secrets that can be compromised or guessed. It is also an open standard that is vendor neutral and supported by most wireless devices1.

• Question 674:

  A small company decided to use a single virtual appliance lo filter spam as well as a reverse proxy to filter traffic to its internal web server. Which of the following did the company MOST likely deploy?

  A. IPS
  B. Firewall
  C. SIEM
  D. UTM
  E. Content filler
  E. Content filler

• Question 675:

  A technician is writing documentation regarding a company's server farm. The technician needs to confirm the server name for all Linux servers. Which of the following commands should the technician run?

  A. ipconfig
  B. nslookup
  C. arp
  D. route
  B. nslookup

  ---

  Explanation/Reference:

  Nslookup (stands for "Name Server Lookup") is a useful command for getting information from the DNS server. It is a network administration tool for querying the Domain Name System (DNS) to obtain domain name or IP address mapping or any other specific DNS record. It is also used to troubleshoot DNS-related problems.

• Question 676:

  A technician is installing a cable modem in a SOHO. Which of the following cable types will the technician MOST likely use to connect a modem to the ISP?

  A. Coaxial
  B. Single-mode fiber
  C. Cat 6e
  D. Multimode fiber
  A. Coaxial

  ---

  Explanation/Reference:

  Coaxial cables are commonly used in cable television and broadband cable Internet installations. They are typically used to connect the cable modem to the wall outlet or the cable modem termination system (CMTS) provided by the ISP.

• Question 677:

  An IT technician is working on a support ticket regarding an unreachable website. The technician has utilized the ping command to the website, but the site is still unreachable. Which of the following tools should the technician use NEXT?

  A. ipconfig
  B. tracert
  C. arp
  D. netstat
  B. tracert

  ---

  Explanation/Reference:

  Use Traceroute or MTR: Traceroute (Windows) or MTR (Linux/macOS) can provide more detailed information about the network path between your computer and the web server. This can help identify where the connection is failing.

• Question 678:

  A technician is consolidating a topology with multiple SSIDs into one unique SSID deployment. Which of the following features will be possible after this new configuration?

  A. Seamless roaming
  B. Basic service set
  C. WPA
  D. MU-MIMO
  A. Seamless roaming
  B. Basic service set
  D. MU-MIMO

• Question 679:

  A network administrator is implementing OSPF on all of a company's network devices. Which of the following will MOST likely replace all the company's hubs?

  A. A Layer 3 switch
  B. A proxy server
  C. A NGFW
  D. A WLAN controller
  A. A Layer 3 switch

  ---

  Explanation/Reference:

  A layer 3 switch is a type of network switch that can perform routing functions in addition to the basic switching functions of a layer 2 switch. OSPF (Open Shortest Path First) is a routing protocol used for distributing routing information within a single autonomous system (AS) and improving the routing efficiency and reliability within a network.

• Question 680:

  Which of the following should be used to associate an IPv6 address with a domain name?

  A. AAAA
  B. A
  C. SOA
  D. TXT
  A. AAAA
