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!

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! -
