• A network administrator views the output from the <code class="args"><em>show ip route</em></code> command. A network that is advertised by both RIP and IGRP appears in the routing table flagged as an IGRP route. Why is the RIP route to this network not used in the routing table?

  গ

  RIP has a higher metric value for that route.

  ঘ

• You type <code class="args"><em>debug ip rip</em></code> on your router console and see that 172.16.10.0 is being advertised to you with a metric of 16. What does this mean?
  ক

  The route is 16 hops away.

  খ

  The route has a delay of 16 microseconds.

  গ

  ক

  Information about a route should not be sent back in the direction from which the original update came.

  খ

  It splits the traffic when you have a large bus (horizon) physical network.

  গ

  It holds the regular updates from broadcasting to a downed link.

  ঘ

  It prevents regular update messages from reinstating a route that has gone down.

• To prevent Service Advertisements (SAPs) from flooding a network, Cisco routers do not forward them. How are services advertised to other networks?
  ক

  Each router builds its own SAP table and forwards that every 60 seconds

  খ

  Each router assigns a service number and broadcasts that

  গ

  SAPs aren’t necessary with Cisco routers

  ঘ

  Cisco routers filter out all SAPs
• By default, Cisco routers forward GNS SAPs to remote networks.
  ক

  False

  খ

  True
• You want to enable both arpa and snap encapsulation on one router interface. How do you do this?
  ক

  The interface can handle multiple encapsulation types with no extra configuration

  খ

  Assign two network numbers, one for each encapsulation type

  গ

  Enable Novell-ether to run multiple encapsulation types

  ঘ

  Both arpa and snap are enabled by default so you don’t have to configure anything
• What does the “IPX maximum-paths 2” command accomplish?
  ক

  It enables load sharing on 2 paths if the paths are equal metric paths

  খ

  It sets up routing to go to network 2

  গ

  It is the default for Cisco IPX load sharing

  ঘ

  It enables load sharing on 2 paths if the paths are unequal metric paths
• As a system administrator, you need to set up one Ethernet interface on the Cisco router to allow for both sap and Novell-ether encapsulations. Which set of commands will accomplish this?
