Which two characteristics apply to Layer 2 switches? (Choose two.)
A.
Increases the number of collision domains
B.
Decreases the number of collision domains
C.
Implements VLAN
D.
Decreases the number of broadcast domains
E.
Uses the IP address to make decisions for forwarding data packets
Explanation:
Layer 2 switches offer a number of benefits to hubs, such as the use of VLANs and each switch
port is in its own separate collision domain, thus eliminating collisions on the segment.
A collision domain is a section of a network connected by a shared medium or through repeaters where data packets can collide with one another when being sent, particularly when using early versions of Ethernet. A network collision occurs when more than one device attempts to send a packet on a network segment at the same time.
Only one device in the collision domain may transmit at any one time, and the other devices in the domain listen to the network in order to avoid data collisions.
A virtual LAN (VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer (OSI layer 2). LAN is an abbreviation of local area network. To subdivide a network into virtual LANs, one configures a network switch or router.
