STP Advanced Features and Variants

Question 1

What is the primary benefit of using Rapid Spanning Tree Protocol (RSTP) over the traditional Spanning Tree Protocol (STP)?

Accepted Answer

It provides faster convergence

Answer

It supports multiple VLANs

Answer

It allows for more complex network topologies

Answer

It reduces the need for switch redundancy

Question 2

What is the function of BPDU Guard in STP?

Accepted Answer

To prevent BPDUs from being sent on edge ports

Answer

To protect against STP BPDUs being sent by unauthorized devices

Answer

To automatically configure STP parameters on a switch

Answer

To increase the speed of STP convergence

Question 3

What does the concept of "Bridge Assurance" in STP aim to accomplish?

Accepted Answer

To ensure that BPDUs are periodically sent on all ports to detect network changes

Answer

To ensure that all network bridges are compliant with STP standards

Answer

To prevent switches from becoming isolated due to network failures

Answer

To keep the STP configuration consistent across all switches

Question 4

In Multiple Spanning Tree Protocol (MSTP), what is the primary advantage of mapping VLANs to MST instances?

Accepted Answer

It reduces the number of STP instances needed, improving scalability

Answer

It improves network security by encrypting VLAN traffic

Answer

It allows each VLAN to use a separate STP topology

Answer

It enables faster convergence times for all VLANs

Question 5

What is the purpose of "Loop Guard" in STP?

Accepted Answer

To prevent alternate and backup ports from becoming designated ports due to network topology changes

Answer

To detect and prevent unauthorized devices from joining the network

Answer

To protect against accidental changes in the STP configuration

Answer

To enhance the speed of STP operations by adjusting timers
