If an autonomous AP maps two WLANs to two VLANs, which port type should connect the AP to the wired network?

A trunk port is required because it allows multiple VLANs to traverse a single physical link. Since the autonomous AP is mapping two WLANs to two distinct VLANs, the switch port connecting to the AP must be configured as a trunk to carry traffic for both VLANs. An access port is incorrect because it can only carry traffic for a single VLAN. LAG (Link Aggregation Group) and EtherChannel are technologies for bundling multiple physical links into a single logical link to increase bandwidth and provide redundancy, but they don't inherently define how VLANs are handled; the bundled links would still need to be configured as trunks to carry multiple VLANs.
