A certain field used in the IP header is 4 binary bits.

a)What is the largest positive decimal number that can be represented by this field?

b)What is the smallest positive decimal number that can be represented by this field?

c)How many possible values can be represented by this field?

Every Ethernet frame contains padding bytes.

a. true b. false

What is the difference between a hub and a switch?

a.Nothing they are two names for the same thing

b.A hub sends all traffic to all connected hosts, but a switch decides where to send traffic based on MAC addresses

c.A switch is a multi-port hub

d.A switch sends all traffic to all connected hosts, but a hub decides where to send traffic based on MAC addresses

Which network card setting configures the interface to send and receive data at the same time?

a. Simplex b. Full-duplex c. Half-duplex d. Halfplex

In a full-duplex switched network, when can collisions occur?

a) A collision will occur when a host tries to send to the switch at the same time that the switch tries to send to the host

b) A collision will occur when two nodes send broadcast frames at the same time

c) A collision will occur when two hosts connected to the switch send frames at the same time

d) A collision will never occur

Identify whether each MAC address is valid or invalid. If invalid, give a reason.
