CompTIA N10-006 Online Questions & Answers

• Question 1131:

  Which of the following performance optimization techniques would be MOST beneficial for a network-wide VoIP setup? (Select TWO).

  A. Proxy server
  B. Traffic shaping
  C. Caching engines
  D. Load balancing
  E. Quality of service
  B. Traffic shaping
  E. Quality of service

  ---

  Traffic shaping retains excess packets in a queue and then schedules the excess for later transmission over increments of time. The result of traffic shaping is a smoothed packet output rate. QoS (Quality of Service) is a major issue in VOIP implementations. The issue is how to guarantee that packet traffic for a voice or other media connection will not be delayed or dropped due interference from other lower priority traffic. Things to consider are: Latency: Delay for packet delivery Jitter: Variations in delay of packet delivery Packet loss: Too much traffic in the network causes the network to drop packets Burstiness of Loss and Jitter: Loss and Discards (due to jitter) tend to occur in bursts

• Question 1132:

  Which of the following spreads out each of the individual wires of a UTP cable onto their own metal connector?

  A. BNC connection
  B. 110 block
  C. Plenum
  D. LC connector
  B. 110 block

• Question 1133:

  Which of the following 802.11 standards transmits the signals the GREATEST distance?

  A. a
  B. b
  C. g
  D. n
  D. n

  ---

  Explanation Explanation/Reference:802.11n uses multiple antennas to increase data rates.

• Question 1134:

  A network technician is setting up a wireless access point that would only allow a certain laptop to be able to access the WAP. By using ACL, which of the following would be filtered to ensure only the authorized laptop can access the WAP?

  A. NetBIOS name filtering
  B. IP address filtering
  C. MAC address filtering
  D. Computer name filtering
  C. MAC address filtering

  ---

  Explanation Explanation/Reference:MAC Filtering (or EUI filtering, or layer 2 address filtering) refers to a security access control method whereby the 48-bit address assigned to each network card is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the use of blacklists and whitelists. While the restriction of network access through the use of lists is straightforward, an individual person is not identified by a MAC address, rather a device only, so an authorized person will need to have a whitelist entry for each device that he or she would use to access the network.

• Question 1135:

  A network technician is connecting three temporary office trailers with a point-to-multipoint microwave radio solution in a wooded area.

  A. Latency
  B. Throttling
  C. Interference
  D. Split horizon
  C. Interference

• Question 1136:

  An administrator is able to list the interfaces on a switch after providing the community string "public". Which of the protocols is the administrator MOST likely using?

  A. Telnet
  B. RADIUS

  C. 802.11g
  D. 802.11n
