Which three statements accurately describe a distance vector protocol? (choose three)

- Examples of this protocol include RIP and IGRP - This protocol determines the direction (vector) and distance (hop count) to any network in the internetwork - This process is also known as "routing by rumor"

Which three metrics are most commonly used by routing protocols to determine a network path?

- Hop count - Bandwidth - Delay

Which three statements accurately describes a lin-state routing protocol? (choose three)

- Link-state protocols respond quickly to network changes - Link-state protocols send periodic updates (link-state refreshes) at long time intervals, approximately once every 30 minutes - link-state routing protocols send periodic updates even if no network changes have ocurred

Which two types of ports do routers have? (choose two)

- Printer // NO - Console // YES - Network // YES - CD-ROM // NO - USB // NO

Which three of the following components are common to routers, switches, and, computers?

- RAM - CPU - Motherboard

Which three of the following statements about the path determination process are accurate? (Choose three)

- Routers evaluate the available paths do a destination - The routing process uses metrics and administrative distances when evaluating network paths - Dynamic routing occurs when information is learned using routing information that is obtained from routing protocols

which two statements best describe the functions of a router in a network? (choose two)

- Routers maintain their routing tables and ensure that other routers know of changes in the network - Routers use the routes in the routing table to determine where to forward packets

Which three of the following statements describe the function of routing tables?

- Routing tables provide an ordered list of known network address - Routing tables contain metrics that are used to determine the desirability of the route - Routing table associations tell a router that a particular destination is either directly connected to the router or that it can be reached via another router (the next-hop router) on the way to the final destination

Arrange steps of the routing process in the correct order

1.- The router receives a packet on one of its interfaces 2.- The router de-encapsulate the frame and uses the protocol information of the frame to determine that the network layer will pass to the IP process 3.- The router checks the destination address in the IP header. Either the packet is destined to the router itself or it needs to be forwarded. If the packet needs to be forwarded, the router searches its routing table to determine where to send the packet. 4.- If the destination network is on a directly attached network, the router will use the ARP process to obtain the MAC address of the next-hop router and forward the packet out the interface indicated in the routing table 5.- The outgoing interface process encapsulates the packet appropriately to the media and sends the packet onto the network segment.

199

2 to the fifth power is

2 multiplied by itself 5 times: 32

IP addresses are represented using:_______

32 bit binary numbers

Matching each routing table population method to its definition: This is an optional entry that is issued when no explicit path to a destination is found in the routing table. this entry can be manually inserted or be populated from a dynamic routing protocol

Default route

Matching each routing table population method to its definition: This entry comes from having interfaces attached to network segments. This is obviously the most certain; if the interface fails or is administratively shut down, the entry the entry for that network will be removed from the routing table

Directly connected network

Which of the following contains routing information that helps a router in determining the routing path?

Routing table

Matching each routing table population method to its definition: These routes are entered manually by a systems administrator directly into the configuration of a router

Static routing

All computers function ussing the :_______

binary system

Matching each routing table population method to its definition: These routes are learned by the router, and the information is responsive to changes in the network so that the router is constantly being updated

dynamic routing
