What layer is a PC NIC?
![DerekAustin26](https://us.v-cdn.net/6030959/uploads/defaultavatar/nE1RZK93BLG3K.jpg)
in CCNA & CCENT
Everywhere I look it says it operates at both layers..
When I take practice exams they usually only want 1 answer..
So which is it??? The answer seems ambiguous and tricky!

A physical nic would be layer 1. However it follows the ethernet standard which is defined at layer 1 and layer 2. -

So how would a question with the answer of physical nic be worded? And how would a question with the answer of Layer 2 be worded? -

If they are asking about MAC addresses, then you can choose L2. If they are talking about NIC cabling in some way, it's L1. -

If they're asking about frames, then it's layer 2:mike: Cisco Certifications -- Collect the Entire Set! -

technically, the transceiver portion of the NIC operates at layer 1, it's what actually puts the bits on the wire and pulls them off. The rest of the NIC operates at layer 2
