What Are Two Potential Network Problems That Can Result From Arp Operation? (Choose Two.)

Address Resolution Protocol

In the OSI model, the ARP (address resolution protocol) is the essential component. The logical address and the MAC address are used for the communication between the computers and the ARO work is to translate or encrypt the logical address to a physical address (MAC).it determines the hardware address of the device.

It has operations and a question arises for its operations in the elective paper: What are two potential network problems that can result from ARP operation? In this topic, we have mentioned the ARP and it’s working along with its operations. The answers to the question are also given in this article. That’s why stay connected to the end!

ARP and Its working

ARP is one of the essential protocols during the data transmission, it helps in the determination of the MAC Address for the IP address at hand. ARP converts the 32-bit IP address to the physical address 48-bits. During the device connected with the local network, ARP is used.

Working:

Suppose the device wants a communication then what does the ARP does? The devices then unfold the header at the Protocol data unit or frames of the data link layer and move them to the network layer. The ARP comes at this point of the transmission.

At this point, the ID of the packets goes or verification with the IP address ID of the destination packet and in case of the match the response to the MAC address of the destination was given or the packet went to the gateway and transfer packet to the connected device in the network and verifies their ID of network. The process remains to continue until the second last reach to the destination where the verification happens and ARP will respond to the destination physical address.

There are the four terms that are used in the ARP and they are given below:

ARP Cache:

The ARP transfer the physical address to its source for future use in case a sudden response is demanded and it is in the ARP table.

ARP Cache timeout:

It is the maximum time of the solved ARP store in the MAC table.

ARP request:

It is used to determine whether the packet reaches the destination physical address or not and it happens by broadcasting it on the network and validate it. Things to know for the validation are given below:

• Check the sender’s MAC address.
• Check the logical address of the sending device.
• The physical address of the source is FF: FF: FF: FF: FF: FF or else.
• The logical address of the recipient.

ARP reply:

When the packet reaches the destination MAC address then the response is given to determine it and then the process of the communication began.

What are two potential network problems that can result from ARP operation? (Choose two.)

1. Static ARP configured manually.
2. On big networks with less bandwidth, multiple ARP transmissions can cause data communication delays
3. . Network attackers could exploit physical and logical address mappings in ARP messages in order to intercept network traffic.
4. Greater ARP requests make the MAC address table overflow.

Answer: the option B AND C are the correct ones the ARP request on a broad level cause the temporary delay in the communication and the hacker also manipulate the physical and logical address by interfering  the network traffic. The overflow occurs in the ARO table, not in the MAC table.
