• Question 414:

  The network interface layer of the TCP/IP model corresponds with which of the following layers of the OSI model? (Select TWO).

  A. Transport layer
  B. Network layer
  C. Session layer
  D. Physical layer
  E. Presentation layer
  F. Data link layer
  D. Physical layer
  F. Data link layer

  ---

  The lowest layer of the OSI Reference Model is the physical layer, which is responsible for the "nitty gritty" details of transmitting information from one place to another on a network. The layer just above the physical layer is the data link layer, called the network interface layer or just the link layer in the TCP/IP architectural model. Its primary job is to implement networks at the local level, and to interface between the hardware-oriented physical layer, and the more abstract, software-oriented functions of the network layer and those above it.

• Question 415:

  A technician has been dispatched to investigate connectivity problems of a recently renovated office. The technician has found that the cubicles were wired so that the network cables were run inside the conduit with the electrical cabling. Which of the following would MOST likely resolve the connectivity issue?

  A. Power-cycle the computers and switches to re-establish the network connection.
  B. Re-run the network cabling through the ceiling alongside the lights to prevent interference.
  C. Test the wiring in the network jacks for faults using a cable verifier.
  D. Re-run the network cabling so that they are 12 inches or more away from the electrical lines.
  D. Re-run the network cabling so that they are 12 inches or more away from the electrical lines.

  The electric cables create electric field around them and can interrupt in internet connectivity as well. It is quite possible that this is the cause which is creating the connectivity issue.

• Question 419:

  Which of the following network protocols is used to resolve FQDNs to IP addresses?

  A. DNS
  B. FTP
  C. DHCP
  D. APIPA
  A. DNS

  ---

  An Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4.

• Question 420:

  While preparing to replace an old CAT3 cable with a CAT6 cable to implement VoIP, a facilities employee mistakenly disconnects the entire patch panel, including valid wiring to live workstations. Which of the following should an administrator use in order to connect those ports FIRST?

  A. Toner
  B. Multimeter
  C. Reflectometer
  D. Cable tester
  A. Toner
