Selected Answer: A
Since the switch does not support Spanning Tree Protocol (STP) but the technician still wants redundant connections, link aggregation (also known as EtherChannel or LACP) is the proper solution. It combines multiple physical links into one logical link, providing both redundancy and increased bandwidth without creating loops — thereby avoiding the need for STP.
