Bridge Protocol Data Units (BPDUs) JN0-364 Practice Questions (Page 1)
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 14 practice questions to prepare you well beyond it.

A network engineer is troubleshooting a spanning-tree issue in a network with three Juniper switches: SW-A, SW-B, and SW-C. SW-A is the root bridge. SW-B is connected to SW-A via port ge-0/0/1 and to SW-C via port ge-0/0/2. SW-C is connected to SW-A via port ge-0/0/1 and to SW-B via port ge-0/0/2. All links are 1 Gbps. The engineer notices that SW-B's port ge-0/0/2 is in the blocking state, but SW-C's port ge-0/0/2 is in the forwarding state. The engineer wants to change the topology so that SW-B's port ge-0/0/2 becomes the designated port and forwards. Which configuration change would achieve this?
