What protocol or technology allows data to transmit over redundant switch links?
- EtherChannel
- DTP
- STP
- VTP
Explanation: EtherChannel is a link aggregation technology that groups multiple physical Ethernet links into a single logical link, allowing data to transmit over redundant paths simultaneously without being blocked by the Spanning Tree Protocol (STP). While STP prevents loops by disabling redundant paths, EtherChannel allows those physical links to remain active and functional by making them appear as a single connection to the network.
