IPv6 and EUI-64 Quiz

What is the main reason for the creation of IPv6 addressing?

• To improve network speed

• To reduce the size of IP addresses

• To increase the number of available addresses

• To enhance security features

Answer explanation

IPv6 addressing was created to increase the number of available addresses.

How many bits does an IPv6 address consist of?

• 128 bits

• 64 bits

• 32 bits

• 16 bits

Answer explanation

An IPv6 address consists of 128 bits, making it the correct choice.

What is the purpose of using double colons in IPv6 address compression?

• To separate the address into different groups

• To add more 0s

• To replace groups of 0s

• To remove leading 0s

Answer explanation

Double colons in IPv6 address compression are used to replace groups of 0s, reducing the address size and making it more concise.

What is the process of converting a MAC address to an EUI-64 address for IPv6?

• Adding 16 bits to the MAC address

• Flipping the seventh bit of the MAC address

• Removing the first 16 bits of the MAC address

• Doubling the MAC address

Answer explanation

The process of converting a MAC address to an EUI-64 address for IPv6 involves flipping the seventh bit of the MAC address. This ensures uniqueness and compatibility with IPv6 addressing.

What is the purpose of the OUI in a MAC address?

• To specify the IP address

• To identify the network interface controller

• To identify the manufacturer

• To indicate the network speed

Answer explanation

The purpose of the OUI in a MAC address is to identify the manufacturer.

What is the significance of adding 'ff:fe' in the middle of an EUI-64 address?

• To separate the OUI and the serial number

• To indicate the end of the address

• To extend the address to 64 bits

• To compress the address

Answer explanation

Adding 'ff:fe' in the middle of an EUI-64 address extends it to 64 bits, allowing for unique identification of devices.

What is the purpose of converting the seventh bit of the MAC address?

• To compress the address

• To specify the network speed

• To indicate a globally unique address

• To indicate a locally assigned address

Answer explanation

The purpose of converting the seventh bit of the MAC address is to indicate a locally assigned address.

What is the value of the hexadecimal character 'D' when converted using the chart?

• F

• E

• C

• B

Answer explanation

The hexadecimal character 'D' has a value of '13' in decimal. According to the chart, 'E' has a value of '14', which is the correct choice.

What is the result of converting the MAC address '8c' to an EUI-64 address?

• 8e2d:aa::4b:98a7

• 8e2d:aa:ff:fe:4b:98a7

• 8e2d:aa:ff:fe:4b:98a7

• 8e2d:aa:fffe:4b:98a7

Answer explanation

Converting the MAC address '8c' to an EUI-64 address results in '8e2d:aa:ff:fe:4b:98a7'. This is the correct choice as it follows the EUI-64 format.

What is the purpose of the EUI-64 address in IPv6?

• To identify the manufacturer

• To indicate the end of the address

• To specify the network speed

• To create a unique IPv6 address

Answer explanation

The purpose of the EUI-64 address in IPv6 is to create a unique IPv6 address.
