What is one benefit of a switched LAN?
A.
It enables the LAN to forward non-IP traffic.
B.
It ensures that all hosts can reach each other by flooding all traffic to all ports.
C.
It limits memory use by eliminating the need for a bridging table.
D.
It limits the collision domain.
The answer should be D.It limits the collision domain.
Pl correct if i am wrong
+1 Muttal
The correct answer IS D!

The answer that as of this comment marked correct is “c”. INCORRECT
Switched LAN has to have a bridge table, without a bridge table it WOULDNT be a SWITCH it would be a HUB (thus it would have to flood the traffic out all ports, instead of associating a port with a layer 2 mac address). This explanation also illustrates how answer B is wrong.
Answer A is nonsensical
I also confuse this question.

Benefits of LAN Switches (Layer 2 Services)
An individual Layer 2 switch might offer some or all of the following benefits:
+ Bandwidth-LAN switches provide excellent performance for individual users by allocating dedicated bandwidth to each switch port (for example, each network segment). This technique is known as microsegmenting.
+ VLANs-LAN switches can group individual ports into logical switched workgroups called VLANs, thereby restricting the broadcast domain to designated VLAN member ports. VLANs are also known as switched domains and autonomous switching domains. Communication between VLANs requires a router.
+ Automated packet recognition and translation-Cisco’s unique Automatic Packet Recognition and Translation (APaRT) technology recognizes and converts a variety of Ethernet protocol formats into industry-standard CDDI/FDDI formats. With no changes needed in either client or server end stations the Catalyst solution can provide an easy migration to 100-Mbps server access while preserving the user’s investment in existing shared 10Base-T LANs.
I have the same idea.
