A network engineer notices that a LAG between two Juniper switches is not passing traffic. The 'show lacp interfaces' command shows that the LACP state is 'Detached' on all member links. What is the most likely cause?

The hash algorithm is misconfigured

The LAG is configured with too few member links

The peer switch is not configured with LACP

The member links are administratively down

A data center has a LAG with two member links between a switch and a server. The server NIC teaming is configured for 'LACP' but the switch is configured for a static LAG. What is the most likely outcome?

The switch will automatically enable LACP

The LAG will form and work correctly

The LAG will form but only one link will be active

The LAG will not form because the server expects LACP negotiation

How does LACP initially establish a LAG between two switches?

By exchanging LACPDUs to agree on which links are part of the LAG

By using the Spanning Tree Protocol to determine the active links

By sending a broadcast message to all switches in the network

By configuring the same IP address on both ends

An administrator has configured a 4-member LAG between two switches. Monitoring shows that one member link carries 80% of the traffic while the other three are underutilized. The traffic consists of many large file transfers between a few servers. What is the most likely cause of this imbalance?

The member links are configured with different speeds

The LAG is configured with a static (non-LACP) mode

LACP is not enabled on the member links

The hash algorithm is not distributing traffic evenly because the traffic has few flows

Part of the High Availability 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 1–3 from this objective — we provide 25 practice questions to prepare you well beyond it.
