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 11 practice questions to prepare you well beyond it.

A network engineer is analyzing a BPDU capture and sees the following fields: root bridge ID = 32768:00:11:22:33:44:55, root path cost = 19, bridge ID = 32768:00:11:22:33:44:66, port ID = 128.1. The switch that sent this BPDU is connected to the root bridge via a 100 Mbps link. What can the engineer conclude about the sender?

A network administrator notices that a switch is not receiving BPDUs from its root port as expected. The switch has been configured with a max age timer of 20 seconds and a hello timer of 2 seconds. How long will the switch wait before it considers the root bridge unreachable and begins recalculating the spanning tree?
