A network administrator is configuring RSTP on a switch that connects to a router. The router is a single device, and the administrator wants to ensure that the port transitions to forwarding immediately when the link comes up. Which configuration is required?

Configure the port as a shared link.

Set the port to a lower port cost.

A network administrator is troubleshooting a topology change in an RSTP network. The administrator notices that a switch is generating topology change notifications (TCNs) frequently, causing unnecessary reconvergence. Which configuration is most likely causing this issue?

Edge mode is enabled on ports connecting to end devices.

The switch has a lower bridge priority than the root bridge.

The switch has a higher port cost on its uplink.

Edge mode is disabled on ports connecting to end devices.

What is the primary reason RSTP converges faster than traditional STP?

RSTP uses an explicit handshake and port roles to transition ports quickly

RSTP does not require a root bridge election

RSTP uses a shorter hello timer

RSTP uses a shorter forward delay timer

A service provider is upgrading its network from traditional STP to RSTP to improve convergence times. The network has redundant links between core switches and access switches. Which improvement does RSTP provide over STP during a link failure?

RSTP reduces the forwarding delay from 15 seconds to 4 seconds.

RSTP eliminates the need for a root bridge by using a distributed algorithm.

RSTP requires all switches to be configured with the same bridge priority to converge faster.

RSTP uses alternate ports to transition to forwarding immediately without waiting for timers.

Part of the Spanning-Tree Protocols domain, which makes up ~8% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~3–5 in this domain), expect 1–1 from this objective — we provide 16 practice questions to prepare you well beyond it.
