CompTIA N10-008 Online Questions & Answers

• Question 271:

  After a firewall replacement, some alarms and metrics related to network availability stopped updating on a monitoring system relying on SNMP. Which of the following should the network administrator do FIRST?

  A. Modify the device's MIB on the monitoring system.
  B. Configure syslog to send events to the monitoring system.
  C. Use port mirroring to redirect traffic to the monitoring system.
  D. Deploy SMB to transfer data to the monitoring system.
  A. Modify the device's MIB on the monitoring system.

  ---

  Explanation/Reference:

  In this scenario, the network administrator should first modify the device's Management Information Base (MIB) on the monitoring system. A MIB is a database used by SNMP to manage and monitor devices in a network. After replacing the firewall, the SNMP MIB on the monitoring system might not be updated to reflect the changes made on the new device, and this might cause some alarms and metrics related to network availability to stop updating.

  By modifying the device's MIB on the monitoring system, the administrator can ensure that the monitoring system can communicate properly with the new firewall and receive updated information on network availability. Configuring syslog, using port mirroring, or deploying SMB are all methods of transferring data to the monitoring system but they do not address the root cause of the problem, which is the lack of updated MIB on the monitoring system.

• Question 272:

  A network technician is troubleshooting a connection to a local server and has verified that the RDP service is running on the server. After running a command, the technician receives the following output:

  

  Which of the following MOST likely describes the issue?

  A. A host-based firewall on the server is blocking the connection.
  B. Too many collisions are occurring on the network segment.
  C. A DoS attack is occurring locally.
  D. A routing loop is in the network.
  A. A host-based firewall on the server is blocking the connection.

• Question 273:

  Which of the following is associated with the session layer of the OSI model?

  A. Data representation
  B. Packets
  C. Sockets
  D. Frames
  C. Sockets

• Question 274:

  A network administrator needs to connect two network closets that are 492ft (150m) away from each other. Which of the following cable types should the administrator install between the closets?

  A. Single-mode fiber
  B. Coaxial
  C. DAC
  D. STP
  A. Single-mode fiber

• Question 275:

  Which of the following is required for hosts to receive DHCP addresses from a server that is located on a different subnet?

  A. DHCP scope
  B. DHCP snooping
  C. DHCP reservations
  D. DHCP relay
  D. DHCP relay

  ---

  Explanation/Reference:

  A DHCP relay is a network device that forwards DHCP requests from clients on one subnet to a DHCP server on another subnet. This allows the DHCP server to assign IP addresses and other network configuration parameters to clients across different subnets. A DHCP scope is a range of IP addresses that a DHCP server can assign to clients. A DHCP snooping is a security feature that filters and validates DHCP messages on a switch. A DHCP reservation is a way to assign a specific IP address to a specific client based on its MAC address. References: Part 2 of the current page talks about DHCP relay and its functions. You can also find more information about DHCP relay on [this page].

• Question 276:

  A network technician is investigating a trouble ticket for a user who does not have network connectivity. All patch cables between the wall jacks and computers in the building were upgraded over the weekend from Cat 5 to Cat 6. The newly installed cable is crimped with a TIA/EIA 568A on one end and a TIA/EIA 568B on the other end.

  Which of the following should the technician do to MOST likely fix the issue?

  A. Ensure the switchport has PoE enabled.
  B. Crimp the cable as a straight-through cable.
  C. Ensure the switchport has STP enabled.
  D. Crimp the cable as a rollover cable.
  B. Crimp the cable as a straight-through cable.

  ---

  Explanation/Reference:

  A straight-through cable is a type of twisted pair cable that has the same wiring standard (TIA/EIA 568A or 568B) on both ends. This is the most common type of cable used for connecting devices of different types, such as a computer and a switch. A cable that has different wiring standards on each end (TIA/EIA 568A on one end and 568B on the other) is called a crossover cable, which is used for connecting devices of the same type, such as two computers or two switches. Therefore, the technician should crimp the cable as a straight-through cable to fix the issue.

• Question 277:

  A non-employee was able to enter a server room. Which of the following could have prevented this from happening?

  A. A security camera
  B. A biometric reader
  C. OTP key fob
  D. Employee training
  B. A biometric reader

• Question 278:

  A network administrator needs to set up a file server to allow user access. The organization uses DHCP to assign IP addresses. Which of the following is the best solution for the administrator to set up?

  A. A separate scope for the file server using a /32 subnet
  B. A reservation for the server based on the MAC address
  C. A static IP address within the DHCP IP range
  D. A SLAAC for the server
  B. A reservation for the server based on the MAC address

  ---

  Explanation/Reference:

  Assigning a DHCP reservation for the server based on its MAC address ensures that the file server will consistently receive the same IP address every time it connects to the network. This approach provides the advantages of DHCP (automatic assignment of IP addresses) while also guaranteeing a specific and consistent IP address for the file server, making it easy for users to access it reliably.

• Question 279:

  Users at a company will require more bandwidth on their wireless laptops because of a migration to the cloud. The company's current infrastructure contains four 802.11n access points, which are creating a bottleneck. Hardware upgrades are not an option. Which of the following configurations will provide a solution?

  A. Increasing RSSI
  B. MIMO
  C. Channel bonding D. Reconfiguring SSID
  C. Channel bonding D. Reconfiguring SSID

• Question 280:

  A. tcpdump
  B. show config
  C. hostname
  D. show route
  E. netstate
  F. show ip arp
