Selected Answer: D When Rapid PVST+ is used, switch ports always enter the blocking state immediately after the boot process 1. The blocking state is the first of the five possible port states in the Rapid PVST+ protocol. In this state, the port does not forward frames but listens to BPDUs to determine the location of the root bridge and the best path to reach it 12. After a port enters the blocking state, it transitions to the listening state and then to the learning state before finally entering the forwarding state. When Rapid PVST+ (Per-VLAN Spanning Tree Plus) is used, switch ports go through a specific state immediately after the boot process. This state is known as the "discarding" state. So, the correct answer is: D. discarding

Selected Answer: C C. is the correct answer.

Discarding port state = RSTP(802.1W), not Rapid PVST+

Selected Answer: D When Rapid PVST+ is used, switch ports enter the: D. discarding This is the initial state in the Rapid Spanning Tree Protocol (RSTP), which is equivalent to the blocking state in traditional STP. In the discarding state, the port does not forward frames, does not learn MAC addresses, and waits for the RSTP algorithm to decide the eventual state of the port based on the network topology.

Explanation: In Rapid PVST+, which is an implementation of Rapid Spanning Tree Protocol (RSTP) for VLANs, switch ports pass through certain states while the network topology is being determined. The states are: Discarding: This is the port's starting state after the switch boots. In this state, the port does not forward frames, does not learn MAC addresses, and does not process incoming frames except for BPDU (Bridge Protocol Data Units) frames. Learning: In this state, the port begins learning MAC addresses but still does not forward frames. This helps populate the MAC address table. Forwarding: In this state, the port forwards frames and keeps learning MAC addresses. This is the operational state for a port that is part of the active topology.

When you enable Rapid PVST+, every port in the device, VLAN, and network goes through the blocking state and the transitory states of learning at power up.

When Rapid PVST+ (Per-VLAN Spanning Tree Plus) is used, the temporary state that switch ports always enter right after the boot process is the **"discarding"** state. During this state, the switch port is not forwarding frames, and it is listening to BPDU (Bridge Protocol Data Unit) messages to determine the topology of the network before moving to the forwarding state. So, the correct answer is: D. **discarding**

Selected Answer: D It´s discarding = D

Selected Answer: D D. discarding1. In this state, ports do not forward frames and are not learning MAC addresses. They listen to BPDU messages to determine the network topology before moving to the forwarding state.
