CompTIA N10-006 Online Questions & Answers

• Question 461:

  A network administrator has been tasked to deploy a new WAP in the lobby where there is no power outlet. Which of the following options would allow the network administrator to ensure the WAP is deployed correctly?

  A. QoS
  B. Install 802.11n WAP
  C. PoE
  D. Parabolic antenna
  C. PoE

  ---

  Explanation Explanation/Reference:Power over Ethernet or PoE describes any of several standardized or ad-hoc systems which pass electrical power along with data on Ethernet cabling. This allows a single cable to provide both data connection and electrical power to devices such as wireless access points or IP cameras.

• Question 462:

  A user reports that several spots within the company's office have intermittent connectivity issues with the newly installed wireless network. There are several WAPs located around the office to provide a strong signal wherever the users are. Which of the following is the MOST likely cause of the problem?

  A. Incompatible network card
  B. Channel overlap
  C. Latency
  D. WEP encryption
  B. Channel overlap

  ---

  Explanation Explanation/Reference:To reduce interference between wireless APs, ensure that wireless APs with overlapping signals use unique channel frequencies. The 802.11b standard reserves 14 frequency channels for use with wireless APs.

• Question 463:

  An IT manager is looking for a solution that can easily trace back suspicious Internet browsing to particular users at a company. Which of the following can BEST provide this functionality?

  A. Layer 3 managed switch
  B. VPN concentrator
  C. Load balancer
  D. Content filter
  D. Content filter

• Question 464:

  A public website using round robin DNS is an example of:

  A. load balancing
  B. QoS
  C. Caching engines
  D. Traffic shaping
  A. load balancing

• Question 465:

  A network administrator is troubleshooting an issue with unstable wireless connections in a residence hall. Students on the first and second floors are reporting the hall's SSID is not visible in the evenings. The network administrator has verified the wireless system is operating normally. Which of the following is the MOST likely cause for the problem reported by students?

  A. Internet router maintenance is scheduled.
  B. An ARP attack is underway.
  C. The SSID is set to hidden.
  D. A jammer is being used.
  A. Internet router maintenance is scheduled.

• Question 466:

  An attack used to find unencrypted information in network traffic is called:

  A. WEP cracking
  B. packet sniffing
  C. ping sweep
  D. social engineering
  B. packet sniffing

• Question 467:

  A network engineer needs to set up a topology that will not fail if there is an outage on a single piece of the topology. However, the computers need to wait to talk on the network to avoid congestions. Which of the following topologies would the engineer implement?

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

  ---

  Token Ring networks are quite rare today. Token Ring networks use the ring topology. Despite being called a Ring topology, the ring is logical and the physical network structure often forms a `star' topology with all computers on the network connecting to a central multistation access unit (MAU). The MAU implements the logical ring by transmitting signals to each node in turn and waiting for the node to send them back before it transmits to the next node. Therefore, although the cables are physically connected in a star, the data path takes the form of a ring. If any computer or network cable fails in a token ring network, the remainder of the network remains functional. The MAU has the intelligence to isolate the failed segment. To ensure that the computers need to wait to talk on the network to avoid congestions, a Token Ring network uses a `token'. The token continually passes around the network until a computer needs to send data. The computer then takes the token and transmits the data beforereleasing the token. Only a computer in possession of the token can transmit data onto the network.

• Question 468:

  Joe, a network technician, is tasked with setting up a new wireless network in an office for office laptops and desktops only. The surrounding offices already have many wireless networks. Joe discovered that over 30 wireless networks were showing up as he completed a wireless survey of the office. Every single one of the networks that Joe was able to see while conducting the wireless survey were 802.11b/g networks. Which of the following should Joe consider before purchasing/ installing the new wireless access points?

  A. Move the WAP so that it is close to the interior walls.
  B. Determine which wireless channels and bands to use to mitigate as much interference as possible.
  C. Turn the SSID broadcasts off to decrease interference.
  D. Determine if the business should relocate to a building with a lot less surrounding wireless networks.
  B. Determine which wireless channels and bands to use to mitigate as much interference as possible.

• Question 469:

  When a switch has multiple paths to reach the root bridge, into which of the following states is the port with the LEAST desirable path placed by the spanning tree protocol?

  A. Forwarding
  B. Bonding
  C. Blocking
  D. Listening
  C. Blocking

• Question 470:

  A user reports intermittent network connectivity from their desktop PC. A technician determines the cause to be a bad wall jack and fixes the jack. Which of the following should the technician do NEXT?

  A. Test the theory
  B. Question the user
  C. Document the outcome
  D. Verify functionality
  D. Verify functionality
