An engineer must create data-link redundancy for the company Cisco Wireless LAN Controller. The engineer has decided to configure LAG-based redundancy instead of port-based redundancy. Which three…

In a LAG configuration all dynamic interfaces are mapped to a single aggregated bundle, so as long as at least one physical member port remains active, all interface traffic continues to flow without manual intervention.

Having multiple untagged dynamic interfaces assigned to the same port is a characteristic of port-based redundancy on the WLC, not of LAG, which consolidates all interfaces into one aggregated bundle.

Connecting redundant interfaces to two separate non-stacked switches is a feature of port-based redundancy; LAG requires all member ports to terminate on the same switch or switch stack.

The WLC LAG implementation uses symmetric session-based hashing, which guarantees that response packets always egress on the same physical port on which the corresponding inbound traffic was received.

While all LAG member ports are active, the WLC's symmetric hashing algorithm does not guarantee even traffic distribution across all links, making full utilization of all link bandwidth an unreliable distinguishing advantage of LAG.

LAG operates by logically grouping physical switch ports into an aggregated link group, and this port-grouping capability is the foundational mechanism from which the other LAG behaviors derive.
