  Explanation/Reference:

  A router is a device that routes data packets between computers in different networks. It is used to connect multiple networks, and it determines the path to be taken by each data packet to its destination computer. A router maintains a routing table of the available routes and their conditions. By using this information, along with distance and cost algorithms, the router determines the best path to be taken by the data packets to the destination computer. A router can connect dissimilar networks, such as Ethernet, FDDI, and Token Ring, and route data packets among them. Routers operate at the network layer (layer 3) of the Open Systems Interconnection (OSI) model. A gateway is a network point that acts as an entrance to another network. On the Internet, a node or stopping point can be either a gateway node or a host (end-point) node. Both the computers of Internet users and the computers that serve pages to users are host nodes. The computers that control traffic within a company's network or at a local Internet service provider (ISP) are gateway nodes. In the network for an enterprise, a computer server acting as a gateway node is often also acting as a proxy server and a firewall server. A gateway is often associated with both a router, which knows where to direct a given packet of data that arrives at the gateway, and a switch, which furnishes the actual path in and out of the gateway for a given packet. Most of the gateways operate at the application layer, but can operate at the network or session layer of the OSI model. Answer option C is incorrect. A repeater operates only at the physical layer of the OSI model. Answer option B is incorrect. A bridge operates at the data link layer of the OSI model.

• Question 246:

  Which of the following protocols is used to share information between routers to transport IP Multicast packets among networks?

  A. RSVP
  B. DVMRP
  C. RPC
  D. LWAPP
  B. DVMRP

  ---

  Explanation/Reference:

  The Distance Vector Multicast Routing Protocol (DVMRP) is used to share information between routers to transport IP Multicast packets among networks. It uses a reverse path-flooding technique and is used as the basis for the Internet's multicast backbone (MBONE). In particular, DVMRP is notorious for poor network scaling, resulting from reflooding, particularly with versions that do not implement pruning. DVMRP's flat unicast routing mechanism also affects its capability to scale. Answer option A is incorrect. The Resource Reservation Protocol (RSVP) is a Transport layer protocol designed to reserve resources across a network for an integrated services Internet. RSVP does not transport application data but is rather an Internet control protocol, like ICMP, IGMP, or routing protocols. RSVP provides receiver-initiated setup of resource reservations for multicast or unicast data flows with scaling and robustness. RSVP can be used by either hosts or routers to request or deliver specific levels of quality of service (QoS) for application data streams. RSVP defines how applications place reservations and how they can leave the reserved resources once the need for them has ended. RSVP operation will generally result in resources being reserved in each node along a path. Answer option C is incorrect. A remote procedure call (RPC) hides the details of the network by using the common procedure call mechanism familiar to every programmer. Like any ordinary procedure, RPC is also synchronous and parameters are passed to it. A process of the client calls a function on a remote server and remains suspended until it gets back the results. Answer option D is incorrect. LWAPP (Lightweight Access Point Protocol) is a protocol used to control multiple Wi-Fi wireless access points at once. This can reduce the amount of time spent on configuring, monitoring, or troubleshooting a large network. This also allows network administrators to closely analyze the network.

• Question 247:

  What is the location of honeypot on a network?

  A. Honeyfarm
  B. Honeynet
  C. Hub
  D. DMZ
  D. DMZ

• Question 248:

  Elden is working as a network administrator at an IT company.

  A. Hybrid virtualization
  B. Hardware-assisted virtualization
  C. Full virtualization
  D. Para virtualization
  B. Hardware-assisted virtualization
