CompTIA N10-005 Online Questions & Answers

• Question 231:

  After a power failure, several users are unable to connect to network devices at the remote office. Which of the following is the MOST likely cause of the issue?

  A. Bad cable
  B. Missing route
  C. Duplicate IP address
  D. Switching loop
  B. Missing route

• Question 232:

  A technician is reviewing the following aggregated information on a server to determine the cause of a user's connection problem:

  

  Which of the following is the technician reviewing?

  A. Syslog server logs
  B. Application logs
  C. Network sniffer logs
  D. SNMPv2 queries
  A. Syslog server logs

  ---

  Syslog server logs are the logs that are saved on a system whenever an instance happens of the wireless device. Reviewing the logs can help him understand the behavior of the WAP as well as the client.

• Question 233:

  In a SOHO environment, placing a VoIP unit on the outside edge of a LAN router enhances which of the following network optimization methods?

  A. Load balancing
  B. Quality of service
  C. Fault tolerance
  D. Traffic shaping
  B. Quality of service

  ---

  In unified communication video, voice, data have only one end gateway so to give priority to avoid delay in voice and video we use Qos.

• Question 234:

  If a technician does not assign an IP address to a device, the DHCP server will assign the device a:

  A. static IP address.
  B. reservation.
  C. dynamic IP address.
  D. MAC address.
  C. dynamic IP address.

• Question 235:

  A SOHO company just installed new 802.11a wireless APs. All company laptops have gigabit LAN ports along with wireless-g cards.

  Which of the following is the issue with this setup?

  A. The laptops will have a max wireless speed of 300Mbps
  B. The wired network is likely not backwards compatible with the gigabit LAN ports on the laptops
  C. The wireless system will only function at a slow 11Mbps
  D. The laptops are only capable of functioning on 2.4GHz spectrum
  D. The laptops are only capable of functioning on 2.4GHz spectrum

• Question 236:

  The network administrator installed a new dipole antenna that extends 100 feet (30.48 meters) from the existing AP. All components are correct, functional, and installed properly. However, during validation, there is a very weak signal coming from the antenna.

  Which of the following is the MOST likely cause of the issue?

  A. The installation exceeds the link limitations
  B. The antenna is mounted for vertical polarization
  C. The dBi output of the antenna is too low
  D. The radio is too powerful for the installation
  A. The installation exceeds the link limitations

  Unlike isotropic antennas, dipole antennas are real antennas. Dipole antennas have a different radiation pattern compared to isotropic antennas. The dipole radiation pattern is 360 degrees in the horizontal plane and 75 degrees in the vertical plane (assuming the dipole antenna is standing vertically) and resembles a donut in shape. Because the beam is "slightly" concentrated, dipole antennas have a gain over isotropic antennas of 2.14 dB in the horizontal plane. Dipole antennas are said to have a gain of 2.14 dBi (in comparison to an isotropic antenna).

• Question 237:

  A network administrator tests a multimode fiber cable from end-to-end on a new link that is down and notices that the dB loss is -.09.

  Which of the following is the MOST likely cause?

  A. TXRX reversed
  B. dB loss too high
  C. dB loss too low
  D. Bad connectors
  A. TXRX reversed

  Some Ethernet switches support medium dependent interface crossover (MDIX),which allows a switch port to properly configure its leads as transmit (Tx) or receive (Rx) leads. You can interconnect such switches with a straight-through cable (as opposed to a crossover cable). However, if a network device does not support MDIX, it needs an appropriate cable (that is, a crossover cable ) to allow its Tx leads to connect to the Rx leads on a connected device, and vice versa. Therefore, care must be taken when selecting cable types interconnecting network components.

• Question 238:

  Users have reported choppy audio in phone conversations since the implementation of SIP phones on the network. Which of the following should be implemented to alleviate the delays?

  A. Caching
  B. VoIP
  C. QoS
  D. SMTP
  C. QoS

  ---

  By Qos we can prioritize the voice packets over data network.So delay and latency will get reduce.

• Question 239:

  Which of the following is used to limit the amount of bandwidth used on a link for different applications to improve overall performance?

  A. QoS
  B. Fault tolerance
  C. Load balancing
  D. Traffic shaping
  D. Traffic shaping

• Question 240:

  Which of the following routing protocols can be utilized as both an IGP and EGP?

  A. EIGRP
  B. RIP
  C. IGRP
  D. RIPv2
  A. EIGRP
