A network has three switches connected in a loop to provide redundancy. The administrator notices that broadcast frames are looping endlessly. What protocol should be enabled to prevent this?

Rapid Spanning Tree Protocol (RSTP) is not needed; just disable one of the links.

Link Aggregation Control Protocol (LACP)

An administrator wants to combine four 1 Gbps links between two switches into a single logical link. What is the primary benefit of this configuration?

Increased bandwidth and redundancy

Which statement correctly differentiates an access port from a trunk port?

Access ports support 802.1Q tagging; trunk ports do not

Access ports carry tagged frames for multiple VLANs; trunk ports carry untagged frames for one VLAN

Access ports are used for inter-switch links; trunk ports are used for end devices

Access ports carry untagged frames for one VLAN; trunk ports carry tagged frames for multiple VLANs

A network has multiple switches with redundant links. The administrator wants to ensure that STP converges quickly when a link fails. Which STP variant should be used?

Multiple Spanning Tree Protocol (MSTP)

Classic Spanning Tree Protocol (STP)

Rapid Spanning Tree Protocol (RSTP)

Ethernet Switching and Bridging Concepts JN0-281 Practice Questions (Page 3)

Part of the Layer 2 Switching and VLANs domain, which makes up ~21% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–13 in this domain), expect 1–2 from this objective — we provide 29 practice questions to prepare you well beyond it.
