Network Hardware Lesson 2

What is the purpose of a MAC address?

• Identify the network card manufacturer
• Send data between hardware on a network
• Encrypt data packets
• Provide a dynamic IP address

How is a MAC address structured?

• 32-bit address divided by hyphens
• 48-bit address divided by colons or hyphens
• 128-bit address divided by colons
• 64-bit address divided by periods

What types of devices use MAC addresses?

• Ethernet, Wi-Fi, and Bluetooth devices
• Wi-Fi and Cellular devices only
• Bluetooth devices only
• Ethernet devices only

How are IPv4 addresses represented?

• As four hexadecimal numbers
• As four binary numbers
• As four octal numbers
• As four denary numbers separated by full stops

What is the main problem with 32-bit IP addresses?

• They provide too much security
• They are too complex to configure
• There aren't enough of them
• They are too slow

What is the total number of unique IP addresses available with IPv4?

• About 2.3 billion
• About 4.3 billion
• About 340 trillion
• About 340 trillion trillion trillion

How many unique devices can IPv6 potentially address?

• 4.3 billion
• 340 million
• 340 trillion trillion trillion
• 232 devices

What is the size of an IPv6 address?

• 32-bit
• 64-bit
• 128-bit
• 256-bit

Which of the following is true about MAC addresses?

• They can be changed easily
• They are assigned by the ISP
• Each network hardware device has a unique MAC address
• They are the same as IP addresses

What distinguishes IPv4 and IPv6?

• IPv4 uses colons; IPv6 uses full stops
• IPv4 addresses are longer
• IPv6 offers improved security
• IPv4 is more recent
