question
It connects multiple cable segments (or devices), and forwards frames to the appropriate segment. Switches have multiple ports and can connect multiple segments or devices. The switch forwards frames to the appropriate port. They function similarly to a hub, except instead of sending packets to all ports, switches send packets only to the destination computer's port.
answer
Which of the following best describes how a switch functions?
question
Repeater Hub A hub and a repeater send signals out all other ports. These devices do not examine the frame or the packet contents. A switch or a bridge use the MAC address in a frame for forwarding decisions. A router uses the IP address in a packet for forwarding decisions.
answer
Which of the following hardware devices regenerates a signal out all connected ports without examining the frame or packet contents? (Select two)
question
When a frame enters a port, the source MAC address is copied from the frame header. Bridges and switches learn addresses by copying the MAC address of the source device and placing it into the MAC address table. The port number which the frame entered is also recorded in the table and associated with the source MAC address. The switch or the bridge cannot record the destination MAC address because it does not know the port that is used to reach the destination device. Bridges and switches operate at Layer 2 and do not use IP addresses (which exist at Layer 3).
answer
How do switches and bridges learn where the devices are located on a network?
question
Send the frame out port 2-8. Because the switch does not know the port that is used to reach the destination device, it will send the frame out all ports except for the port on which the frame was received. After the switch learns the port that is used to reach the destination device, it will send the frame out only that port.
answer
An 8-port switch receives a frame on port number 1. The frame is addressed to an unknown device. What will the switch do?
question
Hub A hub does not create multiple segments on the network. A segment is a portion of the network that has a different media, collision domains, or broadcast domains. A hub simply connects devices using the same media type. All devices are members of the same collision and broadcast domains. On a switch, each switch port is in a separate collision domain. With a router or a firewall, each connected network is a different broadcast domain.
answer
Which of the following devices does not segment the network?

Question
What is the right structure for an essay
Answer
A paragraph is a related group of sentences that develops one main idea. Each paragraph in the body of the essay should contain:
  • a topic sentence that states the main or controlling idea
  • supporting sentences to explain and develop the point you’re making
  • evidence from your reading or an example from the subject area that supports your point
  • analysis of the implication/significance/impact of the evidence finished off with a critical conclusion you have drawn from the evidence.
