Microsoft 98-366 Online Questions & Answers

• Question 131:

  What happens when an 802.11b node starts broadcasting within the range of an 802.llg access point?

  A. The access point will transmit, but the node will be unable to receive.
  B. A connection will be established.
  C. Both the node and the access point will be unable to transmit.
  D. The node will transmit, but the access point will be unable to receive.
  B. A connection will be established.

  ---

  802.11g hardware is fully backward compatible with 802.11b hardware.

• Question 132:

  Which of these cable types transmits data the greatest distance?

  A. Multi-mode fiber
  B. Single-mode fiber
  C. Cat5e
  D. Cat6
  B. Single-mode fiber

  ---

  When working with distances up to 2 km, use multimode optical-fiber cable.

  Like multi-mode optical fibers, single mode fibers do exhibit modal dispersion resulting from multiple spatial modes but with narrower modal dispersion. Single mode fibers are therefore better at retaining the fidelity of each light pulse over

  longer distances than multi-mode fibers.

  Incorrect:

  Cat5e and Cat6 max cable length is 100 metres.

• Question 133:

  What is an example of a network device that associates a network address with a port?

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

  ---

  A router is a Layer 3 gateway device, meaning that it connects two or more networks and that the router operates at the network layer of the OSI model.

  Incorrect:

  not switch: Any switch that provides this 'basic' functionality, operates at the 2nd OSI layer also known as the Datalink Layer. not hub: A network hub, or a repeater, is a simple network device that does not manage any of the traffic coming

  through it. Any packet entering a port is flooded out or "repeated" on every other port, except for the port of entry.

• Question 134:

  The protocol that maps IP addresses to a Media Access Control (MAC) address is:

  A. Internet Message Access Protocol (IMAP).
  B. Dynamic Host Configuration Protocol (DHCP).
  C. Routing Information Protocol (RIP).
  D. User Datagram Protocol (UDP).
  E. Address Resolution Protocol (ARP).
  E. Address Resolution Protocol (ARP).

  ---

  Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address (MAC address) that is recognized in the local network.

• Question 135:

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

  The 802.11n wireless standard specifies a maximum data rate of 54 Mbps.

  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. 10 Mbps
  B. 11-128 Mbps
  C. 300-600 Mbps
  D. No change is needed
  C. 300-600 Mbps

• Question 136:

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

  "WEP" wireless encryption is the most susceptible to interception and decryption.

  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. WPA-AES
  B. WPA2
  C. WPA-PSK
  D. No change is needed
  D. No change is needed

  ---

  Several weaknesses have been discovered using WEP encryption that allows an attacker using readily available software to crack the key within minutes.

• Question 137:

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

  The "NTP" value in a resource record indicates a length of time that other DNS servers use to determine how long to cache information for a record before expiring and discarding it.

  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. TTL
  B. GPS
  C. SOA RR
  D. No change is needed
  A. TTL

  ---

  Time to live (TTL) is what dictates how long it will be until your computer refreshes its DNS related information.

• Question 138:

  HOTSPOT

  Network client computers running Windows 8.1 and Windows 10 are configured to receive IPv4 addresses through DHCP. The DHCP server fails. For each of the following statements, select Yes if the statement is true. Otherwise, select No.

• Question 139:

  If a router cannot determine the next hop for a packet, the router will:

  A. Forward the packet to the default route.
  B. Send the packet back to the packet's source.
  C. Broadcast the packet.
  D. Store the packet in the memory buffer.
  A. Forward the packet to the default route.

  ---

  If there is no next hop, the packets are not policy routed.

  A default route of a computer that is participating in computer networking is the packet forwarding rule (route) taking effect when no other route can be determined for a given Internet Protocol (IP) destination address.

• Question 140:

  HOTSPOT
