• Question 152:

  Which IEEE 802.11 Wi-Fi networking standard requires dual antennas so it can run in all of its supported frequencies?

  A. 802.11a
  B. 802.11b
  C. 802.11g
  D. 802.11n
  D. 802.11n

  ---

  IEEE 802.11n-2009, commonly shortened to 802.11n, is a wireless networking standard that uses multiple antennas to increase data rates.

• Question 153:

  What is an example of a Layer 3 device that connects multiple computers and networks?

  A. Packet
  B. Repeater
  C. Switch
  D. Router
  D. Router

  ---

  A router is a layer 3 device, although some newer switches also perform layer 3 functions.

• Question 154:

  One purpose of a perimeter network is to:

  A. Make resources available to the intranet.
  B. Link campus area networks (CANs).
  C. Link local area networks (LANs).
  D. Make resources available to the Internet.
  D. Make resources available to the Internet.

  ---

  In computer security, a DMZ or demilitarized zone (sometimes referred to as a perimeter network) is a physical or logical subnetwork that contains and exposes an organization's external-facing services to a larger and untrusted network, usually the Internet. The purpose of a DMZ is to add an additional layer of security to an organization's local area network (LAN); an external network node only has direct access to equipment in the DMZ, rather than any other part of the network.

• Question 155:

  Which of the following services masks internal IP addresses from outside the network?

  A. DHCP
  B. WINS
  C. NAT
  D. DNS
  C. NAT

  ---

  The majority of NATs map multiple private hosts to one publicly exposed IP address. In a typical configuration, a local network uses one of the designated "private" IP address subnets (RFC 1918). A router on that network has a private address in that address space. The router is also connected to the Internet with a "public" address assigned by an Internet service provider.

• Question 156:

  A network device that associates a Media Access Control (MAC) address with a port is a:

  A. DSL modem
  B. Hub
  C. Router
  D. Switch
  D. Switch

  ---

  A switch begins learning the local MAC addresses as soon as it is connected to other devices or to a network. This learning capability makes switches easy to use on a network.

  The switch learning process works like this:

  1.As a PC or other networked device sends a frame to another device through the switch, the switch captures the source MAC address of the frame and the interface that received it.

  2.The switch confirms or adds the MAC address and the port to the lookup table.

• Question 157:

  To protect a network when it is connected to the Internet, you should use a:

  A. Bridge
  B. Firewall
  C. Switch
  D. Router
  B. Firewall

  ---

  A firewall is software or hardware that checks information coming from the Internet or a network, and then either blocks it or allows it to pass through to your computer, depending on your firewall settings.

• Question 158:

  The query protocol used to locate resources on a network is:

  A. User Datagram Protocol (UDP).
  B. Lightweight Directory Access Protocol (LDAP)
  C. Tracert
  D. Telnet.
  B. Lightweight Directory Access Protocol (LDAP)

  ---

  The Lightweight Directory Access Protocol (LDAP) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. Directory services play an important role in developing intranet and Internet applications by allowing the sharing of information about users, systems, networks, services, and applications throughout the network.

• Question 159:

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

  The protocol that maps IP addresses to a Media Access Control (MAC) address is Domain Name Systems (DNS).

  Review the underlined text. If it makes the statement correct, select "No change is needed." If the statement is incorrect, select the answer choice that makes the statement correct.

  A. Address Resolution Protocol (ARP)
  B. Dynamic Host Configuration Protocol (DHCP)
  C. Routing Information Protocol (RIP)
  D. No change is needed
  A. Address Resolution Protocol (ARP)

• Question 160:

  Two companies want to share data by using the Internet. Which type of network provides the solution?

  A. Ethernet
  B. Intranet
  C. Extranet
  D. Perimeter
  C. Extranet

  ---

  An extranet is a computer network that allows controlled access from outside of an organization's intranet. Extranets are used for specific use cases including business-to-business (B2B).
