Routing Protocols 2

Which of the following routing protocols is used by routers on the internet for learning and sharing routes? Select one: a. IS-IS b. OSPF c. BGP d. EIGRP e. RIP

BGP

Select one: a. Calculates the total cost to get to a particular network ID and compare that cost to the total cost of all the other routes to get to that same network ID. b. Floods the network with advertisements to all neighbor routers per area in an attempt to converge the network with new route information. c. Recognizes assignment of different autonomous systems and automatically summarizes at network class boundaries. d. Used on a computer network for automating routing decisions and configuration

Calculates the total cost to get to a particular network ID and compare that cost to the total cost of all the other routes to get to that same network ID.

What does Distance Vector Protocols do in dynamic routing? Select one: a. Recognizes assignment of different autonomous systems and automatically summarizes at network class boundaries. b. Floods the network with advertisements to all neighbor routers per area in an attempt to converge the network with new route information. c. Calculates the total cost to get to a particular network ID and compare that cost to the total cost of all the other routes to get to that same network ID. d. Used on a computer network for automating routing decisions and configuration

Calculates the total cost to get to a particular network ID and compare that cost to the total cost of all the other routes to get to that same network ID.

What does Routing Information Protocol (RIP) do? Select one: a. Routes traffic within an Autonomous System (AS) b. Uses paths, rules, and policies instead of a metric for making routing decisions. c. Distance vector used within an autonomous system. Uses hop count as the metric. d. Routes traffic between Autonomous Systems (AS)

Distance vector used within an autonomous system. Uses hop count as the metric.

Routers must use the same type of connection for all routes, such as Ethernet to Ethernet or ATM to ATM. Select one: True False

False

Under which of the following circumstances might you implement BGP on your company network and share routes with Internet routers? Select one: a. If the network is connected to the Internet using public addressing. b. If the network has over 15 hops. c. If the network is connected to the Internet using multiple ISPs. d. If the network has over 15 areas and uses IPv6.

If the network is connected to the Internet using multiple ISPs.

What are two big advantages to using OSPF over RIP? (Select two.) Select one or more: a. OSPF is a modern protocol that does not have legacy problems. b. OSPF runs on all routers, big and small. c. OSPF sends only routing table changes, reducing network traffic. d. OSPF chooses routes based on link speed, not hop count

OSPF chooses routes based on link speed, not hop count , OSPF sends only routing table changes, reducing network traffic.

What is the main difference between RIP and RIPv2? Select one: a. RIP use the hop count for the metric, while RIPv2 uses a relative link cost. b. RIP has a limit of 15 hops, while RIPv2 increases the hop count limit. c. RIP is a distance vector protocol, while RIPv2 is a link state protocol. d. RIP is a classful protocol, while RIPv2 is a classless protocol.

RIP is a classful protocol, while RIPv2 is a classless protocol.

What does Interior Gateway Routing Protocol (IGRP) do in dynamic routing? Select one: a. Used on a computer network for automating routing decisions and configuration b. Floods the network with advertisements to all neighbor routers per area in an attempt to converge the network with new route information. c. Calculates the total cost to get to a particular network ID and compare that cost to the total cost of all the other routes to get to that same network ID. d. Recognizes assignment of different autonomous systems and automatically summarizes at network class boundaries.

Recognizes assignment of different autonomous systems and automatically summarizes at network class boundaries.

Which of the following tasks do routers perform? (Select two.) Select one or more: a. Route data based on logical network addresses. b. Multiplex signals onto the same transmission media. c. Identify devices through hardware addresses. d. Control access to the transmission media. e. Maintain information about paths through an internetwork.

Routes traffic within an Autonomous System (AS)

What information does the next hop entry in a routing table identify? Select one: a. The last router in the path to the destination network. b. A backup router that is used to forward packets addressed to unknown networks. c. The number of routers that the packet must go through to reach the destination network. d. The first router in the path to the destination network.

a. Routes traffic between Autonomous Systems (AS)

What does Enhanced Interior Gateway Routing Protocol (EIGRP) do? Select one: a. Routes traffic between Autonomous Systems (AS) b. Routes traffic within an Autonomous System (AS) c. Hybrid for routing within an AS. Uses a composite number for the metric that indicates bandwidth and delay . The higher the bandwidth, the lower the metric. d. Distance vector used within an autonomous system. Uses hop count as the metric.
