Question 4
What advantage does a packet-switched network have over a circuit-switched network? Selected Answer: (^) c. It allows better sharing of resources
Question 5
__________ is the major problem of distance vector routing algorithms. Count to infinity
Question 6
The order of the protocol stack in the Internet reference model (from top to bottom) is: Answers
application
transport
network
link
physical
Question 7
A computer with an IP address of 172.16.25.8/24 is willing to send a packet to 172.16.25.52/24. Where will the computer send the data packet?
Question 8
Which of the following are properties of circuit switching? Choose two alternatives. NOTE Selected Answers: resource reservation: resources are reserved all along the end-to-end path. dedicated resources: no sharing
Question 9
Which layers in the Internet protocol stack does a router process? list these layers. Correct Answer: Switches process network, link and physical layers (layers 1 through 3).
Question 10
Chose the correct answer. Forwarding is [a]. Routing is [b]. Answers: Chose the correct answer. Forwarding is a router local action. Routing is a network wide action. All Answer Choices performed/executed by switches only a network wide action the action of initializing the router a router local action
Question 11
Compare and contrast Static routing and Dynamic routing algorithms ** Dynamic routing algorithms change the routing paths as the network traffic loads or topology change. While dynamic algorithms are more responsive to network changes, they are also more susceptible to problems such as routing loops and oscillation in routes. Dynamic routing is usually used for large networks, hierarchical networks and possibility of dynamic changes in network topology.
