What technique can be used to improve route convergence in networks using RSTP?

• A. PortFast
• B. STP Tuning
• C. VLAN Tagging
• D. Link Aggregation

Answer: (A)

Using PortFast is an effective technique to improve route convergence in networks utilizing Rapid Spanning Tree Protocol (RSTP). PortFast allows a switch port to skip the listening and learning states that are part of the Spanning Tree Protocol (STP) process, thus transitioning directly to the forwarding state when a device is connected. This is particularly beneficial for ports that are connected to end devices like computers or printers, as it minimizes the time taken for these devices to communicate on the network after being powered on or connected. In scenarios where devices are frequently connected and disconnected, or in environments with a high degree of fluctuation in device connectivity, having PortFast enabled can significantly decrease the overall convergence time, leading to faster response times in the network and improved performance for applications that rely on quick and reliable communications. Other techniques, such as STP Tuning, involve adjusting the parameters of STP itself to optimize performance, but may not provide the immediate benefits that PortFast offers for specific edge device connectivity. VLAN Tagging is related to the management of VLANs within a network rather than directly impacting the convergence timing in RSTP. Link Aggregation can enhance bandwidth and redundancy between switches but does not specifically improve how quickly the network reconverges in response to topology
