CompTIA N10-008 Online Questions & Answers

• Question 971:

  A workstation is configured with the following network details:

  

  Software on the workstation needs to send a query to the local subnet broadcast address. To which of the following addresses should the software be configured to send the query?

  A. 10.1.2.0
  B. 10.1.2.1
  C. 10.1.2.23
  D. 10.1.2.255
  E. 10.1.2.31
  E. 10.1.2.31

  ---

  Explanation/Reference:

  CIDR 27 is 1111 1111.1111 1111.1111 1111.1110 0000 2^5 = 32 hosts per subnet 1st address is network address, last address is broadcast address The user address is 10.1.2.23 which means he reside in the network of 10.1.2.0 to 10.1.2.31

  10.1.2.31 is the last address in that network thus the broadcast address

• Question 972:

  A network resource was accessed by an outsider as a result of a successful phishing campaign. Which of the following strategies should be employed to mitigate the effects of phishing?

  A. Multifactor authentication
  B. Single sign-on
  C. RADIUS
  D. VPN
  A. Multifactor authentication

  ---

  Explanation/Reference:

  Multifactor authentication is a security measure that requires users to provide multiple pieces of evidence before they can access a network resource. This could include requiring users to enter a username, password, and a code sent to the user's mobile phone before they are allowed access. This ensures that the user is who they say they are, reducing the risk of malicious actors gaining access to network resources as a result of a successful phishing campaign.

• Question 973:

  Which of the following ports is a secure protocol?

  A. 20
  B. 23
  C. 443
  D. 445
  C. 443

  2.

  The default gateway needs to be set to 172.28.85.94.

  3.

  The subnet mask needs to be 255.255.255.224.

  Which of the following addresses should the engineer apply to the device?

  A. 172.28.85.93
  B. 172.28.85.95
  C. 172.28.85.254
  D. 172.28.85.255

• Question 975:

  Which of the following layers is where TCP/IP port numbers identify which network application is receiving the packet and where it is applied?

  A. 3
  B. 4
  C. 5
  D. 6
  E. 7
  B. 4

• Question 976:

  Which of the following has the capability to centrally manage configuration, logging, and firmware versioning for distributed devices?

  A. WLAN controller
  B. Load balancer
  C. SIEM solution
  D. Syslog server
  A. WLAN controller

  ---

  Explanation/Reference:

  A WLAN controller is a device that manages and controls multiple wireless access points (WAPs) in a wireless LAN (WLAN). A WLAN controller has the capability to centrally manage configuration, logging, and firmware versioning for

  distributed WAPs. A WLAN controller can also provide load balancing, security, and quality of service (QoS) for the WLAN.

• Question 977:

  A user calls the help desk to report being unable to reach a file server. The technician logs in to the user's computer and verifies that pings fall to respond back when trying to reach the file server. Which of the following would BEST help the technician verify whether the file server is reachable?

  A. netstat
  B. ipconfig
  C. nslookup
  D. traceroute
  D. traceroute

  ---

  Explanation/Reference:

  Traceroute is a network diagnostic tool that allows you to trace the path that network packets take from one device to another. By running traceroute to the file server, the technician can see the sequence of devices and networks that the packets pass through on their way to the file server. This can help the technician to determine if there is a problem with the network connection between the user's computer and the file server, or if the issue is with the file server itself.

• Question 978:

  A malicious user is using special software 10 perform an on-path attack. Which of the following best practices should be configured to mitigate this threat?

  A. Dynamic ARP inspection
  B. Role-based access
  C. Control plane policing
  D. MAC filtering
  A. Dynamic ARP inspection

• Question 979:

  During a risk assessment which of the following should be considered when planning to mitigate high CPU utilization of a firewall?

  A. Recovery time objective
  B. Uninterruptible power supply
  C. NIC teaming
  D. Load balancing
  D. Load balancing

  ---

  Explanation/Reference:

  The recovery time objective (RTO) is the maximum tolerable length of time that a computer, system, network or application can be down after a failure or disaster occurs.

• Question 980:

  Users are moving back into an office that had been vacant for a while. Ten workstations are hooked up in the office, but one workstation cannot obtain a link with the switch. A network engineer checks the documentation and cable labeling, and everything is hooked up as expected. The engineer moves the connection to a different switchport. but a link still cannot be obtained. When the engineer puts a tone generator on the infrastructure cable, no tone is heard at the far end. Which of the following issues is the engineer MOST likely trying to find?

  A. A bad switchport
  B. A break in the cable
  C. A cable short
  D. Cable interference
  B. A break in the cable

  ---

  Explanation/Reference:

  Given the scenario where moving the connection to a different switch port did not resolve the issue and no tone is heard at the far end when using a tone generator on the infrastructure cable, the engineer is most likely trying to find a break in the cable. The absence of a tone signal at the far end indicates a discontinuity or complete break in the cable, which prevents the signal from traveling the entire length of the cable. This would also explain why the workstation cannot obtain a link with the switch, as the physical pathway for the network connection is interrupted.
