Which of the following hardware devices regenerates a signal out all connected ports without examining the frame or packet contents? (Select two.)

1. Hub 2. Repeater

Which of the following devices operate at OSI model Layer 2? (Select two.)

1. Network interface card (NIC) 2. Switch

A switch is associated with which OSI model layer?

Data Link

Your company purchases a new bridge that filters packets based on the MAC address of the destination computer. On which layer of the OSI model is this device functioning?

Data Link

Which of the following devices does not segment the network?

Hub

Which of the following devices operates at the OSI model Layer 1?

Hub

Which of the following best describes a switch functions?

It connects multiple cable segments (or devices) and forwards frames to the appropriate segment.

At which of the following OSI layers does a router operate?

Layer 3

At which OSI layer does a router operate to forward network messages?

Network

At which layer of the OSI model do hubs operate?

Physical

An eight-port switch receives a from on port number 1. The frame is addressed to an unknown device. What will the switch do?

Send the frame out ports two through eight.

Which of the following devices operates at the OSI model Layer 2?

Switch

How do switches and bridges learn where devices are located on a network?

When a frame enters a port, the source MAC address is copied from the frame header.
