Principio del formulario Which statement is true regarding cisco’s RIP_JITTER variable? |
| It prevents the synchronization of routing updates by buffering the updates as they leave the router interfaces. |
| It prevents the synchronization of routing updates by subtracting a random length of time ranging from 0% to 15% of thespecified interval time from the next routing update interval. |
| It prevents the synchronization of routing updates by causing the router to skip every other scheduled update time. |
| It prevents the synchronization of routing updates by forcing the router to listen when its time for other updates on the lines before sending its update. |

3 | -------------------------------------------------
Principio del formulario What does theRIP holddown timer do? |
| ensures an invalid route has a metric of 15 |
| prevents a router from sending any updates after it has introduced a routing loop into the network |
| ensures every new route is valid before sending an update |
| instructs routers to ignore updates, for a specified time or event, about possible inaccessible routes |

Principio del formulario Which two statements are true regarding the function of the RIPv1 routing updates? (Choose two). |
| updates are broadcast only when there are changes to the topology |
| updates are broadcast at regular intervals |
| broadcast are sent to 0.0.0.0 |
| broadcasts are sent to 255.255.255.255 |
| updatescontain the entire network topology |
| only changes are included in the updates |

Principio del formulario

Refer to the exhibit. What path will packets from the 192.168.1.0/24 network travel to reach the 10.0.0.0/8 network if RIP is the active routing protocol? |
| The path will be router A ->router B -> router C -> router E. |
| The path will be router A -> router D -> router E. |
| Router A will load balance between the router A -> router D -> router E and router A -> router B -> router C -> router E paths. |
| Packets will alternate paths depending on the order they arrive at router A. |

6 |-------------------------------------------------
Principio del formulario Which two statements describe EIGRP? (Choose two.) |
| EIGRP can be used with Cisco and non-Cisco routers. |
| EIGRP sends triggered updates whenever there is a change in topology that influences the routing information. |
| EIGRP has an infinite metric of 16. |
| EIGRP sends a partial routing table update, which includes justroutes that have been changed. |
| EIGRP broadcasts its updates to all routers in the network. |

7 | -------------------------------------------------
Principio del formulario What is the purpose of the TTL field in the IP header? |
| used to mark routes as unreachable in updates sent to other routers |
| prevents regular update messages from reinstatinga route that may have gone bad |
| prevents a router from advertising a network through the interface from which the update came |
| limits the time or hops that a packet can traverse through the network before it should be discarded |
| defines a maximum metric value for each distance vector routing protocol by setting a maximum hop count |
