Which statement about static LACP mode is true?

In static LACP (Link Aggregation Control Protocol) mode, the key characteristic is that member interfaces must be manually configured rather than relying on dynamic negotiations. Statement A accurately reflects this by indicating that member interfaces negotiate active interfaces through the exchange of their system and interface details. However, in static mode, this negotiation does not happen automatically; rather, the configuration itself determines which interfaces are active. This means that the configuration on both ends must be aligned for successful communication and operation of aggregated links.

A larger LACP system priority actually indicates a higher priority, which contradicts statement B. Statement C misconstrues the nature of LACP, as the passive role under static configuration does not allow for independent active interface selection; rather, both ends must be configured to agree on which interfaces participate. Lastly, while statement D accurately notes that if devices are not aligned in their interface selections, data forwarding may fail, it does not specifically address the unique aspects of static LACP mode. Thus, statement A stands out as it correctly highlights the need for a precise configuration to achieve successful link aggregation in this context.
