Explanation:
In Rapid PVST+, which is an implementation of Rapid Spanning Tree Protocol (RSTP) for VLANs, switch ports go through specific states during the process of determining the network topology. The states are:
Discarding: This is the initial state of the port after the switch boots up. In this state, the port does not forward frames, learn MAC addresses, or process incoming frames except for BPDU (Bridge Protocol Data Units) frames.
Learning: In this state, the port starts to learn MAC addresses but still does not forward frames. This helps build the MAC address table.
Forwarding: In this state, the port forwards frames and continues to learn MAC addresses. This is the operational state for a port that is part of the active topology.
it´s D
In Rapid PVST+, the first state that a switch port enters after the boot process is the "discarding" state.
During this state, the port doesn´t forward frames but listens to BPDUs to determine the network topology.
After the discarding state, the port transitions through the listening and learning states before reaching the forwarding state, where it actively forwards frames.
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, it does not learn MAC addresses, and it waits for the RSTP algorithm to determine the eventual state of the port based on the network topology.
D. discarding1. In this state, the ports do not forward frames and are not learning MAC addresses. They are listening to BPDU messages to determine the network topology before transitioning to the forwarding state.
When Rapid PVST+ (Per-VLAN Spanning Tree Plus) is used, the temporary state that switch ports always enter immediately 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 transitioning to the forwarding state.
So, the correct answer is:
D. **discarding**
"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. If properly configured, each Layer 2 LAN port stabilizes to the forwarding or blocking state. "

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
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.
