The correct answer is C. ethernet oam ethernet oam max-rate 8 ethernet oam. Option C is correct because establishing Ethernet OAM on a link requires enabling it with ethernet oam and setting the max-rate (maximum OAMPDUs per second), not the min-rate - max-rate 8 controls the upper bound of OAM PDU transmission, which is the relevant rate parameter for…

Explanation
Option C is correct because establishing Ethernet OAM on a link requires enabling it with ethernet oam and setting the max-rate (maximum OAMPDUs per second), not the min-rate - max-rate 8 controls the upper bound of OAM PDU transmission, which is the relevant rate parameter for link monitoring. Critically, C omits mode passive, leaving OAM in its default active mode, which is required so the device can initiate OAM discovery; at least one peer must be active for the handshake to complete.
Why the distractors fail:
- A uses
min-rate(wrong parameter) and addsmode passive, both of which are incorrect - you can't initiate OAM discovery in passive mode. - B correctly uses
max-rate 8but addsmode passive, which prevents this device from initiating OAM; if both peers are passive, discovery never completes. - D uses
min-rateinstead ofmax-rateand is incomplete - it's missing the required OAM enable statement in proper form.
Memory tip: Think "MAX and ACTIVE" - Ethernet OAM uses max-rate (upper bound on PDUs sent), and needs at least one active peer to drive discovery. If you see min-rate or passive in a standalone config, it's a trap.
