Microsoft Microsoft Certifications 98-366 Questions & Answers

• Question 91:

  Which two of the following are connectivity options for wide area networks (WANs)? (Choose two.)

  A. Token ring

  B. Ethernet

  C. Dial-up

  D. Leased line

  Correct Answer: CD

  Token ring and Ethernet are used in LANs.

• Question 92:

  A private network that allows members of an organization to exchange data is an:

  A. Extranet

  B. Ethernet

  C. Intranet

  D. Internet

  Correct Answer: C

  An intranet is a computer network that uses Internet Protocol technology to share information, operational systems, or computing services within an organization. This term is used in contrast to extranet, a network between organizations, and instead refers to a network within an organization.

• Question 93:

  In which physical network topology is each computer connected to a central point?

  A. Star

  B. Mesh

  C. Ring

  D. Bus

  Correct Answer: A

  In local area networks with a star topology, each network host is connected to a central hub with a point-to-point connection.

• Question 94:

  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.

  Correct Answer: A

  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 95:

  The function of a router is to:

  A. Provide IP subnet masks for hosts.

  B. Forward traffic to other networks.

  C. Broadcast routing tables to clients.

  D. Store tables for name resolution.

  Correct Answer: B

  A router is a device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP's network. Routers are located at gateways, the places where two or more networks connect.

• Question 96:

  To directly connect the Ethernet network interface cards (NICs) of two computers, you should use a: A. Crossover cable

  B. Straight cable

  C. Rollover cable

  D. Coaxial cable

  Correct Answer: A

  An Ethernet crossover cable is a type of Ethernet cable used to connect computing devices together directly. Normal straight through cables were used to connect from a host network interface controller (a computer or similar device) to a network switch, hub or router.

• Question 97:

  One reason to replace an unmanaged switch with a managed switch is to:

  A. Manage the routing tables.

  B. Support multiple VLANS.

  C. Reduce collision domains.

  D. Route between networks,

  Correct Answer: B

  A multilayer switch (MLS) is a computer networking device that switches on OSI layer 2 like an ordinary network switch and provides extra functions on higher OSI layers.

  The major difference between the packet switching operation of a router and that of a Layer 3 switch is the physical implementation. In general-purpose routers, packet switching takes place using software that runs on a microprocessor, whereas a Layer 3 switch performs this using dedicated application-specific integrated circuit (ASIC) hardware.

• Question 98:

  In addition to switching, multilayer switches also:

  A. Provide Layer 3 routing functions.

  B. Interface with CAT3, CATS, CAT5e, and fiber optics.

  C. Support 10 MB, 100 MB, and 1 GB local area network (LAN) ports.

  D. Operate by using only Layer 1 and 2 protocols.

  Correct Answer: A

• Question 99:

  You need to divide a network into three subnets.

  Which device should you use?

  A. Hub

  B. Bridge

  C. Router

  D. Segmenter

  Correct Answer: C

  You can use a router to divide your network into subnets.

• Question 100:

  The type of connector used on a 100BaseT Ethernet cable is:

  A. RJ-11

  B. RJ-45.

  C. TNC.

  D. BNC.

  Correct Answer: B
