Which value can you modify to configure a specific interface as the preferred forwarding interface?
Click on the arrows to vote for the correct answerA. B. C. D.
To configure a specific interface as the preferred forwarding interface, you would modify the port priority. The correct answer is B.
The concept of a preferred forwarding interface is associated with the Spanning Tree Protocol (STP) used in Ethernet networks to prevent loops. When multiple paths exist between switches in a network, STP determines the best path to forward frames based on a set of criteria, including port priority.
Port priority is a configurable value assigned to each interface on a switch, and it determines the priority of that interface when STP is calculating the best path for forwarding frames. A lower port priority value means that the interface is more preferred for forwarding frames.
To configure a specific interface as the preferred forwarding interface, you would assign a lower port priority value to that interface than to the other interfaces in the same STP instance. This will cause STP to prefer that interface as the forwarding interface for frames.
The other answer options are not correct:
The interface number is a unique identifier assigned to each interface, and it does not affect STP forwarding decisions.
The VLAN priority is a value assigned to each VLAN for Quality of Service (QoS) purposes, and it does not affect STP forwarding decisions.
The hello time is a timer used in the STP protocol to detect changes in the network topology, and it does not determine the preferred forwarding interface.
