In RSTP, a backup port can replace a faulty root port.
In RSTP, a backup port can replace a faulty root port.
In RSTP (Rapid Spanning Tree Protocol), a backup port provides redundancy for a designated port (not the root port) within the same collision domain. An alternate port, on the other hand, provides redundancy for the root port by offering an alternate path to the root bridge. Therefore, a backup port cannot replace a faulty root port; an alternate port would serve that purpose.
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. An alternate port acts as a backup of the root port and provides an alternate path from the designated bridge to the root bridge. https://support.huawei.com/enterprise/es/doc/EDOC1100117012/2bd0e592/rstp-port-roles-and-port-states
B, false for this. Back up for root port should be alternate port
must be false
The should be B
ANSWER IS FALSE
