MULTIPLE SELECT QUESTION

Which statement is true about broadcast and collision domains?
Adding a router to a network will increase the size of the collision domain.
The size of the collision domain can be reduced by adding hubs to a network.
Adding a switch to a network will increase the size of the broadcast domain.
The more interfaces a router has the larger the resulting broadcast domain.

What is one function of a Layer 2 switch?
duplicates the electrical signal of each frame to every port
learns the port assigned to a host by examining the destination MAC address
forwards data based on logical addressing

What is the significant difference between a hub and a Layer 2 LAN switch?
A hub divides collision domains, and a switch divides broadcast domains.
A switch creates many smaller collision domains, and a hub increases the size of a single collision domain.
Each port of a hub is a collision domain, and each port of a switch is a broadcast domain.
A hub forwards frames, and a switch forwards only packets.
