Task 503

What is the primary purpose of a MAC address in networking?

• Identifying a device's IP address on the network

• Identifying the physical hardware of a network device

• Providing a domain name to IP address translation

• Encrypting data packets for secure transmission

How many bits are in an IPv4 address?

• 32 bits

• 48 bits

• 64 bits

• 128 bits

Which of the following is an example of a valid IPv4 address?

• 192.168.1.1

• 00:1A:2B:3C:4D:5E

• FE80::0202:B3FF:FE1E:8329

• 192.168.300.1

MAC addresses are typically represented in which format?

• Octal

Which layer of the OSI model uses MAC addresses for communication?

• Application

• Network

• Data Link

• Physical

How many bits are in a MAC address?

• 32

• 48

• 64

• 128

What is the main difference between a MAC address and an IP address?

• MAC addresses are temporary, while IP addresses are permanent

• MAC addresses identify hardware, while IP addresses identify network locations

• MAC addresses are 32-bit, while IP addresses are built into the hardware
