- Q1
What is the primary role of a MAC address in a network?
To assign devices to different organizations
To uniquely identify each networking device or interface
To replace an IP address during data transfer
To serve as a temporary identifier for devices on a network
60s - Q2
Which of the following is true about IP addresses?
They are hardcoded into the device by the manufacturer.
They are temporary identifiers that are unique within a network.
They are permanent and cannot be changed.
They uniquely identify a device on any network globally.
60s - Q3
What does ARP (Address Resolution Protocol) do in a network?
Helps a device find the MAC address associated with an IP address.
Ensures secure encryption of data during transmission.
Converts IP addresses into human-readable names.
Broadcasts the physical location of devices in a network.
120s - Q4

30s - Q5
Why must devices on a network have unique MAC addresses?
To allow them to belong to multiple networks simultaneously.
To enable them to communicate securely over the internet.
To prevent duplication of IP addresses.
To ensure devices can be uniquely identified on the network.
120s - Q6
What is a key difference between a MAC address and an IP address?
A MAC address uses decimal notation, while an IP address uses hexadecimal notation.
A MAC address is temporary, while an IP address is permanent.
