CompTIA N10-008 Online Questions & Answers

• Question 831:

  Which of the following is true about an IP address if the first bit is a one and the second bit is a zero?

  A. The address is a Class A address.
  B. The address is a Class B address.
  C. The address is a Class C address.
  D. The address is a Class D address.
  B. The address is a Class B address.

• Question 832:

  A technician is investigating an issue with connectivity at customer's location. The technician confirms that users can access resources locally but not over the internet The technician theorizes that the local router has failed and investigates further. The technician's testing results show that the route is functional: however, users still are unable to reach resources on the internal.

  Which of the following describes what the technician should do NEXT?

  A. Document the lessons learned
  B. Escalate the issue
  C. identify the symptoms.
  D. Question users for additional information
  B. Escalate the issue

  ---

  Explanation/Reference:

  Among the options given, B is indeed the one conforming to CompTIA's methodology. C and D should have been done exhaustively in the first place. A comes last after a solution has been shown to work.

• Question 833:

  Which of the following topologies requites the MOST connections when designing a network?

  A. Mesh
  B. Star
  C. Bus
  D. Ring
  A. Mesh

• Question 834:

  A network administrator wants to reduce overhead and increase efficiency on a SAN. Which of the following can be configured to achieve these goals?

  A. Port aggregation
  B. Traffic shaping
  C. Jumbo frames
  D. Flow control
  C. Jumbo frames

  ---

  Explanation/Reference:

  In a Storage Area Network (SAN), large amounts of data are frequently transferred, which can result in overhead and decreased efficiency. Jumbo frames can be used to reduce overhead and increase efficiency by increasing the maximum transmission unit (MTU) size for a network. By increasing the MTU size, jumbo frames can reduce the overhead associated with transmitting large amounts of data, resulting in improved performance for large data transfers, such as those that occur in a SAN.

  Port aggregation (A) combines multiple physical links into a single logical link to increase the bandwidth of a network. Traffic shaping (B) is used to control the flow of data and prioritize certain types of network traffic. Flow control (D) is used to regulate the amount of data that can be transmitted on a network to prevent network congestion. While these technologies can also play a role in improving network efficiency, they are not directly related to reducing overhead in a SAN specifically.

• Question 835:

  A network technician is configuring a wireless access point and wants to only allow company-owned devices to associate with the network. The access point uses PSKs, and a network authentication system does not exist on the network. Which of the following should the technician implement?

  A. Captive portal
  B. Guest network isolation
  C. MAC filtering
  D. Geofencing
  C. MAC filtering

  ---

  Explanation/Reference:

  MAC filtering is a method of allowing only company-owned devices to associate with the network by using their MAC addresses as identifiers. A MAC address is a unique identifier assigned to each network interface card (NIC) by the manufacturer. MAC filtering can be configured on the wireless access point to allow or deny access based on the MAC address of the device. This way, only devices with known MAC addresses can connect to the network.

• Question 836:

  Which of the following is the LARGEST MTU for a standard Ethernet frame?

  A. 1452
  B. 1492
  C. 1500
  D. 2304
  C. 1500

• Question 837:

  A network administrator is trying to identify a device that is having issues connecting to a switchport. Which of the following would BEST help identify the issue?

  A. A syslog server
  B. Change management records
  C. A rack diagram
  D. The security log
  C. A rack diagram

• Question 838:

  Which of the following is the MOST economical way for Sandy, a technician, to implement 10- Gigabit Ethernet at a datacenter?

  A. 10GBaseLR
  B. 10GBaseSR
  C. 10GBaseX
  D. 10GBaseT
  D. 10GBaseT

• Question 839:

  A company has a large number of employees that need VPN access from home. Which of the following is the BEST solution for deploying and managing the remote access?

  A. Site-to-site VPN
  B. Network-based firewall
  C. SSL VPN
  D. Host-based firewall
  C. SSL VPN

• Question 840:

  Which of the following allows for an devices within a network to share a highly reliable time source?

  A. NTP
  B. SNMP
  C. SIP
  D. DNS
  A. NTP

  ---

  Explanation/Reference:

  Network Time Protocol (NTP) is a protocol used to maintain a highly accurate and reliable clock time on all devices within a network. NTP works by synchronizing the time of all the devices within a network to a single, highly accurate time source. This allows for the time of all the devices to be kept in sync with each other, ensuring a consistent and reliable time source for all devices within the network.
