What happens to traffic in an ESI LAG when one of the member links fails?

All traffic is dropped until the link is restored

The entire LAG is shut down to prevent loops

Traffic is rerouted through a different EVPN instance

Traffic is redistributed across the remaining member links

Which protocol is commonly used in redundant campus networks to prevent loops while allowing redundant links?

Link Aggregation Control Protocol (LACP)

Open Shortest Path First (OSPF)

Virtual Router Redundancy Protocol (VRRP)

A campus network has two access switches connected to two distribution switches. The access switches are configured with two uplinks each, one to each distribution switch. The network team wants to use all four uplinks for traffic while ensuring that a single link or switch failure does not cause a loop. Which approach should they implement?

Configure a Spanning Tree Protocol (STP) instance and let it block redundant links to prevent loops.

Configure a Link Aggregation Group (LAG) on each access switch, bundling both uplinks to the same distribution switch.

Enable Rapid Spanning Tree Protocol (RSTP) and set the root bridge to one of the distribution switches.

Configure MC-LAG on the distribution switches and a LAG on each access switch, with each LAG containing one link to each distribution switch.

What is the primary purpose of node redundancy in a device-level high availability design?

To increase the number of ports available on a single device

To reduce the latency of network traffic

To ensure that if one node fails, another node can take over its functions

To encrypt all traffic between network devices

What is a best practice for designing redundant campus networks?

Use link aggregation to combine multiple links between switches for redundancy and bandwidth

Place all servers on the same access switch

Use a single core switch to simplify management

Disable Spanning Tree Protocol to improve performance

Redundancy and High Availability JN0-1103 Practice Questions (Page 3)

Part of the Network Management and Reliability domain, which makes up ~12% 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 1–2 from this objective — we provide 38 practice questions to prepare you well beyond it.
