Question

Suppose you need a port aggregation protocol to aggregate the bandwidth on the connection between a wireless access controller $($WLC$)$ and the wired production switch that provides redundancy overriding the default spanning$-$tree operation of shutting down one of the links.

What port aggregation protocol will you configure to create a one$-$ to$-$one connection between the WLC and the production switch?

The port aggregation protocol $($PAgP$)$

The rapid spanning$-$tree protocol $($RSTP$)$

The link control aggregation protocol $($LCAP$)$

The link aggregation protocol $802\mathrm{.}3$ad
