Which statement is true for a device with a MAC address of B8-31-B5-80-41-4F?

AThe device OUI is B8-31-B5 and the device NIC serial number is 80-41-4F

BThe device OUI is B8-31 and the device NIC serial number is B5-80-41-4F

CThe device OUI is 80-41-4F and the device NIC serial number is B8-31-B5

DThe device OUI is B8-31-B5 and the device serial number is MD5 hash is 80-41-4F

Show Suggested Answer

Suggested Answer: A

A MAC address is divided into two parts: the Organizationally Unique Identifier (OUI) and the Network Interface Controller (NIC) serial number. The OUI is the first three octets of the MAC address and is unique to the manufacturer. The NIC serial number is the last three octets and is unique to the device itself. Therefore, for the MAC address B8-31-B5-80-41-4F, the OUI is B8-31-B5, and the NIC serial number is 80-41-4F.

Not sure about that, seems too simple.

Wait, is the NIC serial number really just the last part?

B8-31-B5 is the OUI for sure, no doubt!

The OUI is definitely B8-31-B5.

I feel like I might be mixing up the definitions here. Is the OUI always the first part? I need to double-check that.

This question seems similar to one we practiced where the OUI was clearly defined. I hope I got this right!

I'm not entirely sure, but I think the NIC serial number is the last three octets, which would be 80-41-4F.

I remember the OUI is the first three octets of the MAC address, so I think it's B8-31-B5.

I'm a little confused by the different options here. I know MAC addresses are structured in a specific way, but I'm not sure I fully understand how to parse this one and determine the right answer. I'll have to review my notes on MAC address formats before deciding.

Okay, I've got this. The MAC address is B8-31-B5-80-41-4F, so the OUI (Organizationally Unique Identifier) is B8-31-B5 and the device NIC serial number is 80-41-4F. Answer A is correct.

Hmm, I'm a bit unsure about this one. I know MAC addresses have a specific format, but I'm not totally confident in my ability to break this down and identify the OUI and serial number. I'll have to think it through step-by-step.

This looks like a straightforward question about MAC addresses. I'll need to carefully analyze the format and structure of the MAC address to determine the correct answer.

I'm not even going to bother with this question. I'm just going to stare at the MAC address and hope it magically tells me the answer. Maybe if I rub my eyes really hard, the solution will appear!

I think the answer is D because of the MD5 hash.

Ooh, Option D is trying to get sneaky with the MD5 hash, but that's not how MAC addresses are structured. Nice try, but I'm going with Option A.

Hah, Option C is just plain silly. The OUI can't be the last 3 bytes, that's not how MAC addresses work. Come on, people, let's use our brains here!

I'm pretty sure it's Option B. The OUI is the first 2 bytes, and the NIC serial number is the last 4 bytes. Easy peasy!

Option A is the correct answer. The OUI (Organizationally Unique Identifier) is the first 3 bytes of the MAC address, which in this case is B8-31-B5. The remaining 3 bytes represent the device's NIC serial number, which is 80-41-4F.
