  The following are the valid steps for securing routers and devices:

  Configure access list entries to prevent unauthorized connections and traffic routing.

  Use a complex password for a router's administrative console.

  Keep routers in locked rooms.

  Keep routers updated with the latest security patches.

  Use monitoring an equipment to protect routers and devices.

  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. 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 security patch is a program that eliminates a vulnerability exploited by hackers.

• Question 583:

  Which of the following are the distance-vector routing protocols? Each correct answer represents a complete solution. Choose all that apply.

  A. IS-IS
  B. OSPF
  C. IGRP
  D. RIP
  C. IGRP
  D. RIP

  ---

  Explanation/Reference:

  Following are the two distance-vector routing protocols: RIP: RIP is a dynamic routing protocol used in local and wide area networks. As such, it is classified as an interior gateway protocol (IGP). It uses the distance-vector routing algorithm. It employs the hop count as a routing metric. RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination. It implements the split horizon, route poisoning, and hold-down mechanisms to prevent incorrect routing information from being propagated. IGRP: Interior Gateway Routing Protocol (IGRP) is a Cisco proprietary distance vector Interior Gateway Protocol (IGP). It is used by Cisco routers to exchange routing data within an autonomous system (AS). This is a classful routing protocol and does not support variable length subnet masks (VLSM). IGRP supports multiple metrics for each route, including bandwidth, delay, load, MTU, and reliability. Answer options B and A are incorrect. OSPF and IS-IS are link state routing protocols.

• Question 587:

  Consider a scenario consisting of a tree network. The root Node N is connected to two man nodes N1 and N2. N1 is connected to N11 and N12. N2 is connected to N21 and N22. What will happen if any one of the main nodes fail?

  A. Failure of the main node affects all other child nodes at the same level irrespective of the main node.
  B. Does not cause any disturbance to the child nodes or its tranmission
  C. Failure of the main node will affect all related child nodes connected to the main node
  D. Affects the root node only
  C. Failure of the main node will affect all related child nodes connected to the main node

  A. Express card
  B. WAP
  C. WNIC
  D. Wireless repeater
  E. None
  B. WAP

  Explanation/Reference:

  A wireless access point (WAP) is a device that allows wireless communication devices to connect to a wireless network using Wi-Fi, Bluetooth, or related standards. The WAP usually connects to a wired network, and it can transmit data between wireless devices and wired devices on the network. Each access point can serve multiple users within a defined network area. As people move beyond the range of one access point, they are automatically handed over to the next one. A small WLAN requires a single access point. The number of access points in a network depends on the number of network users and the physical size of the network. Answer option C is incorrect. A wireless network interface card (WNIC) is a network card that connects to a radio-based computer network, unlike a regular network interface controller (NIC) that connects to a wire-based network such as token ring or ethernet. A WNIC, just like a NIC, works on the Layer 1 and Layer 2 of the OSI Model. A WNIC is an essential component for wireless desktop computer. This card uses an antenna to communicate through microwaves. A WNIC in a desktop computer is usually connected using the PCI bus. Answer option A is incorrect. ExpressCard, a new standard introduced by PCMCIA, is a thinner, faster, and lighter modular expansion for desktops and laptops. Users can add memory, wired or wireless communication cards, and security devices by inserting these modules into their computers. ExpressCard slots are designed to accommodate modules that use either Universal Serial Bus (USB) 2.0 or the PCI Express standard. ExpressCard modules are available in two sizes, i.e., 34 mm wide (ExpressCard/34) and 54 mm wide (ExpressCard/54). Both modules are 75 mm long and 5 mm high. An ExpressCard/34 module can be inserted in either a 54 mm slot or a 34 mm slot, but an ExpressCard/54 requires a Universal (54 mm) slot. However, an extender can be used with ExpressCard/34 slot to connect the ExpressCard/54 module from outside of the computer. Both the modules are identical in performance. They take full advantage of the features of the PCI Express or USB 2.0 interfaces. The only difference between them is that the ExpressCard/54 form-factor, due to its larger surface area, allows for greater thermal dissipation than does an ExpressCard/34. As the performance does not vary with module size, module developers usually prefer to fit their applications into the smaller ExpressCard/34 form factor. But some applications, such as SmartCard readers, and CompactFlash readers, require the extra width of an ExpressCard/54 module. Answer option D is incorrect. A wireless repeater is a networking device that works as a repeater between a wireless router and computers. It is used to connect a client to the network when the client is out of the service area of the access point. If the wireless repeater is configured properly, it extends the range of the wireless LAN network.
