Question 554

An ARP request is broadcasted and sends the following request:

"Who is 192.168.1.200? Tell 192.168.1.55"

At which of the following layers of the OSI model does this request operate?

    Correct Answer: B

    An ARP (Address Resolution Protocol) request operates at the Data Link layer of the OSI model. ARP is used to map an IP address, which operates at the Network layer, to a MAC address, which operates at the Data Link layer. Therefore, the ARP request 'Who is 192.168.1.200? Tell 192.168.1.55' is functioning at the Data Link layer.

Discussion
b0ugi3Option: B

ARP happens at layer 2, where switches operate

UDoIT2021Option: B

Address Resolution Protocol (ARP) is a layer 2 protocol used to map MAC addresses to IP addresses.

Petter07Option: D

Should be a "D": Network. ARP operates at layer 3

freeman016Option: B

An ARP (Address Resolution Protocol) request operates at the Data Link layer of the OSI model. ARP is used to map an IP address (which operates at the Network layer) to a MAC address (which operates at the Data Link layer). The ARP request "Who is 192.168.1.200? Tell 192.168.1.55" is used to find the MAC address corresponding to the IP address 192.168.1.200. Therefore, the correct answer is: B. Data link

SecPlus2022Option: B

ARP works between Layers 2 and 3. The MAC address exists on Layer 2, the data link layer. The IP address exists on Layer 3, the network layer. Based on the context of this question, the given answer is correct.
