Section 3 - Network Devices

Which network component connects a device to transmission media and allows the device to send and receive messages?

• Peripheral

• Protocol

• Network interface card

• Server

At which OSI model layer does a media converter operate?

• Layer 1

• Layer 2

• Layer 3

• Layer 4

Which of the following are true about the MAC address?

• 32-bit address

• 48-bit address

• 64-bit address

• represented with decimal numbers 0-255

• represented with hexadecimal numbers

Which of the following best describes how a switch functions?

• It connects multiple cable segments (or devices) and broadcasts frames to all of its ports.

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

• It connects multiple segments of different architectures. It translates frames and broadcasts them to all its ports.

• It connects multiple segments of different architectures. It translates frames and forwards them to the appropriate segment.

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

• Send the frame out ports two through eight.

• Send the frame out all eight ports.

• Drop the frame.

• Send the frame out the destination port.

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

• Network

• Session

• Physical

• Transport

• Data Link

You are the network administrator for a small organization. Recently, you contracted with an ISP to connect your organization's network to the internet to provide users with internet access. Since doing so, it has come to your attention that an intruder has invaded your network from the internet on three separate occasions. What type of network hardware should you implement to prevent this from happening again?

• Switch

• Firewall

• Router

• CSU/DSU

You have a server that has a 100BaseFX network interface card that you need to connect to a switch. The switch only has 100BaseTX switch ports. Which device should you use?

• Gateway

• Bridge

• Repeater

• Media converter

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

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

• When a frame enters a port, the destination IP address is copied from the frame header.

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

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

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

• Router

• Repeater

• Switch

• Hub

• Gateway
