Which statement accurately describes a key difference between RSTP and legacy STP?

RSTP requires all switches to be configured with the same bridge priority to operate correctly

RSTP uses timers to determine when a port transitions to forwarding, while legacy STP uses handshakes between switches

RSTP introduces new port roles (alternate and backup) and merges the blocking and listening states into a single discarding state

RSTP is only supported on Juniper devices, while legacy STP is a Cisco proprietary protocol

A network administrator notices that a switch port is stuck in the discarding state and never transitions to forwarding. What is the most likely cause?

The port is in learning state and will transition to forwarding after the forward delay timer expires

The port is configured as an edge port and is waiting for a BPDU to arrive

The port is an alternate or backup port that is intentionally blocking to prevent a loop

The switch has a lower bridge priority than the root bridge, causing all ports to block

What is the purpose of configuring an interface as an edge port in RSTP?

To allow the port to transition to forwarding immediately without waiting for the RSTP handshake

To enable the port to send and receive BPDUs on a shared link

To increase the bridge priority of the switch to make it more likely to become the root bridge

To force the port to become the designated port on the segment

What is the primary purpose of Rapid Spanning Tree Protocol (RSTP) in an Ethernet network?

To provide authentication and encryption for management traffic between switches

To segment a large broadcast domain into smaller broadcast domains

To provide redundancy by allowing multiple active paths between switches while preventing Layer 2 loops

To increase the bandwidth of a single link by aggregating multiple physical links into one logical link

A network administrator needs to verify that a specific interface on a Juniper switch is configured as an edge port. Which command should the administrator use?

Part of the Spanning Tree domain, which makes up ~11% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–7 in this domain), expect 1–1 from this objective — we provide 18 practice questions to prepare you well beyond it.
