Ccna Section One: Internetworking Models Questions

Front 1

What is a broadcast domain?

Back 1

A broadcast domain is the set of hosts and network devices that will receive all broadcasts sent on a network segment.

Front 2

Using CSMA/CD, a node does what before sending traffic?

Back 2

Using Carrier Sense Multiple Access with Collision Detection, the
node will first listen to the wire before sending traffic.

Front 3

If two nodes send a packet at the same time and they collide, what
happens next?

Back 3

The nodes wait a random amount of time and then retransmit.

Front 4

What’s the main difference between how switches and routers handle
broadcasts?

Back 4

Switches will forward broadcasts, but routers won’t.

Front 5

Of hubs, switches, repeaters, and bridges, which devices are typically
used to break up a collision domain?

Back 5

Switches and bridges break up collision domains.

Front 6

What device regenerates an electrical signal, allowing it to travel
further than it could on its own?

Back 6

A repeater.

Front 7

Of hubs, routers, switches, repeaters, and bridges, which is typically
used to break up a broadcast domain?

Back 7

Routers break up broadcast domains.

Front 8

What is the uppermost layer of the OSI model?

Back 8

The Application layer.

Front 9

Name four main purposes of the Application layer.

Back 9

The Application layer ensures the remote partner is available; that the
needed resources for this communication are available; and that both
sides of the communication agree on data integrity procedures.
Authentication also occurs at this layer.

Front 10

Name three main purposes of the Presentation layer.

Back 10

Operating system compatibility, proper data encapsulation for
network transmission, and data formatting.

Front 11

What layer handles the building and teardown of the connection
between the two end points?

Back 11

The Session layer handles building and tearing down the connection.
