LUll I let utvU TO LiveUSIVIA/CD control IUYY to access to (). We also studied the format of Ethernet LAN f. bus or logical bus data from NIC to NIC. Two issues involving Ethernet networks require special configuratio first issue is performance. As networks grow and traffic increases ac Ethernet performance tends to degrade. Performance is typically in hubs with . The added intelligence of a switch boosts over switches performance by isolating traffic to its own workgroup. Another issue is broadcast containment. In many networks, broadca provided by devices that reside above the Data Link Layer, such as today are based on switches, which inherently do not provide broad containment. VLANs provide broadcast containment at the Datal simplifying the process of assigning users to workgroups. Module Review 1. Why is a jamming message sent out over an Ethernet a Warn other stations that a collision has been detected . ietration

Explanation / Answer

)Answer is a:

To warn other statations that a collision has been detected.

Explanation:The jam signal is not a frame. It's not even data. It's purpose is to simply dump a continuous stream of "1"s onto the wire so that any other device transmitting will have a collision.

2)Answer is c(IEEE 802.3)

3)Answer is c

Explanation:

The main difference between Version II and IEEE frames is that the Type field in Version II has been replaced with a 2-byte Length field in the IEEE formats

4)Answer is c(Gigabit Ethernet)

5)Aswer is a(100 m)

Explanation:

UTP cable does not have a maximum length.

However, the protocol that runs over UTP has a maximum length for performance and technical reasons.

6)Answer is d:

7)Answer is b:

8)Answer is b and c

Explanation:

Preserving the 802.3/Ethernet frame and size formats at the MAC interface:

and It is anticipated that PoE Support for 10GBASE-T will be considered by this group as a possible objective.

9)Answer is c:

Explanation:

Switches have increased available network bandwidth.

10)Answer is d:

11)Answer is b:

Explanation:

Performance is increased by reducing broadcast traffic.

12)Aswer is True
