Which operational command is used to verify the overall status of an aggregate interface (ae0) and its member links?

show configuration interfaces ae0

A data center is deploying a new storage array that requires high bandwidth and redundancy to the core switches. The administrator decides to use a LAG. What is the primary benefit of using a LAG in this scenario?

It guarantees packet ordering across all links

It provides a single logical link with increased bandwidth and automatic failover

It eliminates the need for Spanning Tree Protocol

It reduces latency by using multiple paths simultaneously

An administrator has configured a LAG with LACP in active mode on both switches. The 'show lacp interfaces' command shows that the LACP state is 'Current' on all member links. What does this indicate?

LACP is disabled on the aggregate interface

LACP is still negotiating and the LAG is not yet operational

LACP has failed and the LAG is down

LACP has successfully negotiated and the LAG is operational

What happens to traffic when a member link of a LAG fails?

The switch sends a notification to the network administrator and stops forwarding

The entire LAG is shut down to prevent loops

Traffic is redistributed across the remaining member links

All traffic is dropped until the link is restored

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.
