  C. ping

  D. netstat

  Correct Answer: D

  netstat (network statistics) is a command-line tool that displays network connections for the Transmission Control Protocol (both incoming and outgoing), routing tables, and a number of network interface (network interface controller or

  software-defined network interface) and network protocol statistics.

• Question 62:

  This question requires that you evaluate the underlined text to determine if it is correct.

  A "secondary zone" is the first DNS zone to which all updates for the records that belong to that zone are written.

  Select the correct answer if the underlined text does not make the statement correct. Select 'No change is needed" if the underlined text makes the statement correct.

  A. Primary zone

  B. Stub zone

  C. Conditional forwarding zone

  D. No change is needed.

  Correct Answer: A

  When a zone that this DNS server hosts is a primary zone, the DNS server is the primary source for information about this zone, and it stores the master copy of zone data in a local file or in AD DS.

• Question 63:

  Which Microsoft network service can you use to establish a connection to a corporate LAN without any user action?

  A. VPN

  B. Remote Desktop

  C. DirectAccess

  D. Nap

  Correct Answer: C

  DirectAccess allows remote users to securely access internal network file shares, Web sites, and applications without connecting to a virtual private network (VPN). An internal network is also known as a private network or intranet. DirectAccess establishes bi-directional connectivity with an internal network every time a DirectAccess-enabled computer connects to the Internet, even before the user logs on. Users never have to think about connecting to the internal network and IT administrators can manage remote computers outside the office, even when the computers are not connected to the VPN.

• Question 64:

  What are two characteristics of fiber optic cable? (Choose two.)

  A. Conducts electricity

  B. Requires metal conduit

  C. Supports splicing

  D. Requires a polish for end connectors

  Correct Answer: CD

  C: A mechanical splice is a junction of two or more optical fibers that are aligned and held in place by a self-contained assembly (usually the size of a large carpenter's nail).[1] The fibers are not permanently joined, just precisely held together so that light can pass from one to another.

  D: Modern connectors typically use a "physical contact" polish on the fiber and ferrule end. This is a slightly convex surface with the apex of the curve accurately centered on the fiber, so that when the connectors are mated the fiber cores come into direct contact with one another.

  Note: Optical fiber connectors are used to join optical fibers where a connect/disconnect capability is required. Due to the polishing and tuning procedures that may be incorporated into optical connector manufacturing, connectors are generally assembled onto optical fiber in a supplier's manufacturing facility.

• Question 68:

  This question requires that you evaluate the underlined text to determine if it is correct.

  The four IEEE standards, 802.11a, b, g, and n, are collectively known as "mobile ad hoc" networks.

  IEEE 802.11 is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area network (WLAN) computer communication in the 2.4, 3.6, 5, and 60 GHz frequency bands. They are created and maintained by the IEEE LAN/MAN Standards Committee (IEEE 802). The base version of the standard was released in 1997, and has had subsequent amendments. The standard and amendments provide the basis for wireless network products using the Wi-Fi brand.
