Which of the following technologies implements inter-device link aggregation, and can be used to build an active-active system to provide traffic load balancing and backup protection?
M-LAG (Multi-Chassis Link Aggregation Group)is a technology that allowslink aggregation across two physical devices, enabling:
Active-active system deployment
Traffic load balancing
Backup protection without relying on stacking
UnlikeEth-Trunk, which aggregates links on the same device,M-LAGextends this functionality across multiple devices.
LLDPis a discovery protocol andStackrefers to virtual device technology, not specifically inter-device link aggregation.
