CompTIA N10-008 Online Questions & Answers

• Question 921:

  A network administrator Is looking at switch features and is unsure whether to purchase a model with PoE. Which of the following devices that commonly utilize PoE should the administrator consider? (Select TWO)

  A. VoIP phones
  B. Cameras
  C. Printers
  D. Cable modems
  E. Laptops
  F. UPSs
  A. VoIP phones
  B. Cameras

  ---

  Explanation/Reference:

  Power over Ethernet (PoE) is a technology that allows network-connected devices to receive power over the same Ethernet cables that are used for data transfer. PoE is commonly used to power devices such as VoIP phones and cameras, making it an ideal choice for network administrators looking for a cost-effective solution. PoE is not typically used for other devices such as printers, cable modems, laptops, and UPSs.

• Question 922:

  A technician is troubleshooting a user's connectivity issues and finds that the computer's IP address was changed to 169.254.0.1.

  Which of the following is the most likely reason?

  A. Two or more computers have the same IP address in the ARP table.
  B. The computer automatically set this address because the DHCP was not available.
  C. The computer was set up to perform as an NTP server.
  D. The computer is on a VPN and is the first to obtain a different IP address in that network.
  B. The computer automatically set this address because the DHCP was not available.

  ---

  Explanation/Reference:

  IP addresses beginning with 169.254. are called link-local addresses or APIPA (Automatic Private IP Addressing)1. They are assigned by the computer itself when it cannot reach a DHCP server to obtain a valid IP address from the network2. This can happen for several reasons, such as a faulty router, a misconfigured network, or a disconnected cable3. To troubleshoot this issue, the technician should check the network settings, the router configuration, and the physical connection of the computer. The technician should also try to renew the IP address by using the command ipconfig /renew in Windows or dhclient in Linux. If the problem persists, the technician may need to contact the network administrator or the ISP for further assistance.

• Question 923:

  Which of the following attacks MOST likely utilizes a botnet to disrupt traffic?

  A. DDoS
  B. Deauthentication
  C. Social engineering
  D. Ransomware
  E. DNS poisoning
  A. DDoS

• Question 924:

  A network administrator is checking to see if anything has changed. Which of the following steps of the troubleshooting methodology is involved?

  A. Identify the problem.
  B. Test the theory.
  C. Establish a theory.
  D. Document findings.
  B. Test the theory.

  ---

  Explanation/Reference:

  According to the CompTIA troubleshooting methodology1, testing the theory is the step where the network administrator verifies if the problem is caused by a specific factor or change. This step involves checking the system logs, running diagnostic tools, or performing other tests to confirm or eliminate the possible cause.

• Question 925:

  A company has multiple offices around the world. The computer rooms in some office locations are too warm Dedicated sensors are in each room, but the process of checking each sensor takes a long time. Which of the following options can the company put In place to automate temperature readings with internal resources?

  A. Implement NetFlow.
  B. Hire a programmer to write a script to perform the checks
  C. Utilize ping to measure the response.
  D. Use SNMP with an existing collector server
  D. Use SNMP with an existing collector server

  ---

  Explanation/Reference:

  SNMP (Simple Network Management Protocol) is a protocol that allows network devices to communicate with a management server. By using SNMP, the company can set up an SNMP agent on each sensor, which will report its temperature readings to an existing collector server. This will enable the company to monitor the temperatures of all their sensors in real-time without the need for manual checks. Additionally, SNMP's scalability means that even if the company adds more rooms or sensors, the existing system can be easily expanded to accommodate them.

• Question 926:

  A company joins a bank's financial network and establishes a connection to the clearinghouse servers in the range 192 168.124.0/27. An IT technician then realizes the range exists within the VM pool at the data center. Which of the following is the BEST way for the technician to connect to the bank's servers?

  A. NAT
  B. PAT
  C. CIDR
  D. SLAAC
  A. NAT

• Question 927:

  A company's web server is hosted at a local ISP. This is an example of:

  A. colocation
  B. an on-premises data center.
  C. a branch office.
  D. a cloud provider.
  A. colocation

  ---

  Explanation/Reference:

  Colocation refers to the practice of housing privately-owned servers and networking equipment in a third-party data center facility. In this scenario, the company's web server is hosted at a local ISP, which means that the server is physically located at the ISP's data center facility and is not on-premises at the company's own facility. The company likely rents rack space, power, cooling, and network connectivity from the ISP to house their server.

  On-premises data center refers to a company-owned facility that houses its own servers and networking equipment. A branch office is a remote location of a company, typically with its own set of IT resources. A cloud provider refers to a third-party company that provides cloud computing services, which typically involve hosting applications and data in the provider's data center facilities.

• Question 928:

  Which of the following is a benefit of the spine-and-leaf network topology?

  A. Increased network security
  B. Stable network latency
  C. Simplified network management
  D. Eliminated need for inter-VLAN routing
  B. Stable network latency

  ---

  Explanation/Reference:

  The spine and leaf topology has a number of advantages:

  1.

  Each server is only ever a single hop from the backbone, making network latency more predictable.

  2.

  There are multiple redundant paths between a leaf switch and the backbone, allowing for load balancing and failover.

  3.

  As there are no direct connections between spine switches in the backbone or between leaf switches, the network is loop free and does not need to run spanning tree. Instead, each leaf switch runs a protocol called Equal Cost Multipathing (ECMP) to distribute traffic between the links to the spine switches.

• Question 929:

  A network technician 13 troubleshooting a specific port on a switch. Which of the following commands should the technician use to see the port configuration?

  A. show route
  B. show Interface
  C. show arp
  D. show port
  B. show Interface

  ---

  Explanation/Reference:

  To see the configuration of a specific port on a switch, the network technician should use the "show interface" command. This command provides detailed information about the interface, including the current configuration, status, and statistics for the interface.

• Question 930:

  Which of the following IEEE standards explains the characteristics of how PoE should operate in a switched network?

  A. 802. 11ac
  B. 802. 1q
  C. 802. 1 X
  D. 802. 3af
  D. 802. 3af
