CompTIA N10-008 Online Questions & Answers

• Question 421:

  A technician is investigating a misconfiguration on a Layer 3 switch. When the technician logs in and runs a command, the following data is shown:

  

  Which of the following commands generated this output?

  A. show route
  B. show config
  C. show interface
  D. tcpdump
  E. netstat -s
  A. show route

  ---

  Explanation/Reference:

  The command that generated this output is "show route".

  The output shows the routing table entries for the switch, with the network address, next hop IP address, and outgoing interface for each route. This information is used by the switch to determine the best path for forwarding packets to their destination.

• Question 422:

  A network engineer needs to enable device monitoring using authentication and encryption. Which of the following protocols offers this option?

  A. ESP
  B. SNMPv3
  C. NetFIow
  D. SSLv3
  B. SNMPv3

  ---

  Explanation/Reference:

  SNMPv3 is a protocol that offers device monitoring using authentication and encryption. SNMP stands for Simple Network Management Protocol, and it is a standard way of collecting and organizing information about network devices, such as routers, switches, servers, printers, and so on. SNMPv3 is the latest version of SNMP, and it provides enhanced security features, such as data integrity, data origin authentication, data confidentiality, and access control. SNMPv3 can use different algorithms to encrypt and authenticate the communication between the network management system and the network devices12.

• Question 423:

  Lisa, a technician, is tasked to monitor various analog POTS lines for voice activity. Which of the following hardware tools would be used?

  A. Butt set
  B. Toner probe
  C. Wire mapper
  D. Cable certifier
  A. Butt set

• Question 424:

  A network technician travels to a remote office to set up a new SOHO for the company. Wireless networking should be used at the remote office. The network technician sets up all the related wireless network equipment, and the last step is to connect the users' devices to the company network. To complete this step, which of the following should be used to secure the remote network location?

  A. Host-based firewalls
  B. WPA2/WPA
  C. Open access
  D. Port filtering
  B. WPA2/WPA

• Question 425:

  Which of the following provides redundancy on a file server to ensure the server is still connected to a LAN even in the event of a port failure on a switch?

  A. NIC teaming
  B. Load balancer
  C. RAID array
  D. PDUs
  A. NIC teaming

  ---

  Explanation/Reference:

  NIC teaming (also known as network interface card teaming or link aggregation) is a technique that allows multiple network interface cards (NICs) to be combined into a single logical interface. By using NIC teaming, the file server can be connected to the network through multiple physical connections, providing redundancy and increasing bandwidth.

  If one of the NICs or ports fails, the remaining NICs can continue to handle network traffic, ensuring that the file server remains connected to the LAN. This helps to improve network reliability and availability, and reduces the risk of downtime.

• Question 426:

  A PC user who is on a local network reports very slow speeds when accessing files on the network server. The user's PC Is connecting, but file downloads are very slow when compared to other users' download speeds. The PC's NIC should be capable of Gigabit Ethernet. Which of the following will MOST likely fix the issue?

  A. Releasing and renewing the PC's IP address
  B. Replacing the patch cable
  C. Reseating the NIC inside the PC
  D. Flushing the DNS cache
  B. Replacing the patch cable

  ---

  Explanation/Reference:

  A slow download speed can be caused by a faulty patch cable, which is the cable used to connect the user's PC to the network server. If the patch cable is damaged, the connection will be slower than expected, resulting in slow download speeds. Replacing the patch cable is the most likely solution to this issue, as it will provide a new, reliable connection that should allow for faster download speeds.

• Question 427:

  Which of the following connector types would Sandy, a network technician, use to connect a serial cable?

  A. RJ-11
  B. BNC
  C. LC
  D. DB-9
  D. DB-9

• Question 428:

  A company rents out a large event space and includes wireless internet access for each tenant. Tenants reserve a two-hour window from the company each week, which includes a tenant-specific SSID. However, all users share the company's network hardware.

  The network support team is receiving complaints from tenants that some users are unable to connect to the wireless network. Upon investigation, the support team discovers a pattern indicating that after a tenant with a particularly large attendance ends its sessions, tenants throughout the day are unable to connect.

  The following settings are common to all network configurations: Which of the following actions would MOST likely reduce this Issue? (Select TWO).

  

  A. Change to WPA encryption
  B. Change the DNS server to 10.1.10.1.
  C. Change the default gateway to 10.0.0.1.
  D. Change the DHCP scope end to 10.1.10.250
  E. Disable AP isolation
  F. Change the subnet mask lo 255.255.255.192.
  G. Reduce the DHCP lease time to four hours.
  D. Change the DHCP scope end to 10.1.10.250
  G. Reduce the DHCP lease time to four hours.

• Question 429:

  A network administrator wants to ensure devices on the network are not susceptible to published exploits. Which of the following will the administrator MOST likely conduct?

  A. A port scan
  B. A vulnerability scan
  C. A packet analysis
  D. A network log review
  B. A vulnerability scan

  A. Media converter
  B. F-type connector
  C. Small form-factor pluggable
  D. Punchdown block
  A. Media converter
