Hmm, let me think... Ah, got it! The 802.1ag loopback is a non-intrusive ping, while the 802.3ah one actually loops the customer data. B and C are the winners!

I agree, the 802.1ag loopback is just a ping, not intrusive like the 802.3ah one.

B and C are the way to go. The 802.1ag loopback is a ping-like test, while the 802.3ah one is an intrusive loop of the actual traffic.
