In RSTP, a backup port can replace a faulty root port.
In RSTP, a backup port can replace a faulty root port.
In Rapid Spanning Tree Protocol (RSTP), a backup port does not replace a faulty root port. In RSTP, an alternate port is used to replace a faulty root port, providing an alternate path from the bridge to the root bridge. A backup port, on the other hand, is used to provide a redundant path to the same network segment and does not replace the root port.
La respuesta es la B An alternate port acts as a backup of the root port and provides an alternate path from the designated bridge to the root bridge. A backup port acts as a backup of the designated port and provides a backup path from the root bridge to the related network segment.
A. True In Rapid Spanning Tree Protocol (RSTP), a backup port can indeed replace a faulty root port. RSTP introduces the concept of Alternate and Backup ports. An Alternate port is designated to replace a failed designated port, and a Backup port is designated to replace a failed root port. This feature helps in rapid convergence by quickly transitioning to an alternative path if a primary path fails.
