d.
To communicate via inter-networking, a device does not require a MAC address.

Solutions

Expert Solution

a.

Correct Answer: False

Explanation:

A NIC(Network Interface Card) is hardware that contains the MAC address that is used to connect with the internet.

An IP address is an identifier or label used to identify a machine on the internet or a particular network. Each of the devices on the internet must have a MAC address for identification. The NIC is not assigned a permanent IP address.

So, the given statement is false.

b.

Correct Answer: False

Explanation:

A NIC(Network Interface Card) is hardware that contains the MAC address that is used to connect with the internet. An IP address is assigned dynamically by DHCP and can change when you attach your computer to a different network but the MAC address is permanent.

So, the given statement is false.


c.

Correct Answer: True

Explanation:

An IP address is an identifier or label used to identify a machine on the internet or a particular network. Each of the devices on the internet must have an IP address for identification. An IP address is assigned dynamically by DHCP and can change when you attach your computer to a different network.

So, the given statement is true.


d.

Correct Answer: False

Explanation:

A NIC(Network Interface Card) is hardware that contains the MAC address that is used to connect with the internet.

Each of the devices on the internet must have a MAC address for identification.

To communicate via inter-networking, a device does require a MAC address, without MAC address the device can't communicate with the internet.

So, the given statement is false.

e.

Correct Answer: True

Explanation:

ARP protocol is used with IPv4 protocol and it helps to resolve the address of a specific computer or network device by mapping the address to the hardware address that is used by the data link protocol.

To communicate with a device on another subnetwork, a device uses Address Resolution Protocol (ARP) to get the MAC address of the destination device or receiver.

The RARP is used to get the IP address.

So, the given statement is true.
