CompTIA N10-005 Online Questions & Answers

• Question 61:

  Users are reporting that external web pages load slowly. The network administrator determines that the Internet connection is saturated. Which of the following is BEST used to decrease the impact of web surfing?

  A. Caching
  B. Load balancing
  C. Port filtering
  D. Traffic analyzer
  A. Caching

  ---

  In computer science, a cache is a component that transparently stores data so that future requests for that data can be served faster. The data that is stored within a cache might be values that have been computed earlier or duplicates of original values that are stored elsewhere. If requested data is contained in the cache (cache hit), this request can be served by simply reading the cache, which is comparatively faster.

• Question 62:

  The components of a NIC function at which of the following layers of the OSI model? (Select TWO).

  A. Layer 1
  B. Layer 2
  C. Layer 3
  D. Layer 4
  E. Layer 5
  A. Layer 1
  B. Layer 2

• Question 63:

  Which of the following TCP/IP model layers does the OSI model Presentation layer map to?

  A. Transport
  B. Internet
  C. Application
  D. Network Interface
  C. Application

  ---

  The Application layer provides applications the ability to access the services of the other layers and defines the protocols that applications use to exchange data. There are many Application layer protocols and new protocols are always being developed.

• Question 64:

  An administrator needs to install a WAP in a location where there is no electrical wiring. Which of the following should the administrator use to complete a successful installation?

  A. Coaxial
  B. Wireless bridge
  C. PoE
  D. Multimode fiber
  C. PoE

  ---

  PoE provides both data and power connections in one cable, so equipment doesn't require a separate cable for each need.

• Question 65:

  A user is unable to open up websites on the Internet from a browser. The administrator determines that the workstation can ping its local gateway, but not the remote web server. At which of the following layers of the OSI model does the problem MOST likely exist?

  A. Data link
  B. Network
  C. Session
  D. Physical
  B. Network

• Question 66:

  Which of the following copper cable types should be chosen to run gigabit speeds through a dropped ceiling that returns airflow?

  A. Non-Plenum CAT5
  B. Non-Plenum CAT5e
  C. Plenum CAT5
  D. Plenum CAT5e
  D. Plenum CAT5e

  ---

  Cat 5e is a twisted pair cable for carrying signals. This type of cable is used in structured cabling for computer networks such as Ethernet. The cable standard provides performance of up to 100 MHz and is suitable for 10BASE-T, 100BASETX (Fast Ethernet), and 1000BASE-T (Gigabit Ethernet).

• Question 67:

  When a packet that is entering a switch port is encapsulated, which of the following is the switch performing?

  A. 802.1q
  B. Collision avoidance
  C. Port mirroring
  D. STP
  A. 802.1q

  ---

  Encapsulation is the term associated with 802.1q which is enabled by default on many devices.

• Question 68:

  Which of the following network performance optimization methods allows for frequently accessed sites to be housed locally, thereby reducing bandwidth requirements?

  A. Load balancing
  B. Traffic policing
  C. Caching engines
  D. Traffic shaping
  C. Caching engines

• Question 69:

  A technician is sorting patch cables into four bins labeled coaxial, crossover, straight-through, and fiber. The technician has a cable with RJ-45 ends. The wires at one end of the cable start with an orange-white wire, while the wires at the other end of the cable start with a green wire.

  Into which of the following bins should this cable be placed?

  A. Crossover
  B. Fiber
  C. Straight-through
  D. Coaxial
  A. Crossover

• Question 70:

  An administrator has added QoS settings to the LAN switches prioritizing RTP.

  Which of the following systems is the Administrator MOST concerned with in this scenario?

  A. Phone communications
  B. Web site downloads
  C. Streaming video clients
  D. Client bittorrent abilities
  A. Phone communications
