What is the key redundancy feature of a LAG?

The logical link remains operational if at least one member link is up

It provides a backup switch that takes over if the primary switch fails

It ensures that no packets are lost during a member link failure

It automatically reroutes traffic to a different VLAN

Which Junos configuration stanza is used to create a LAG and assign member links?

set interfaces ge-0/0/0 ether-options ...

set interfaces vlan unit 0 family inet ...

set interfaces ae0 aggregated-ether-options ...

set interfaces lo0 unit 0 family inet ...

What is the role of the Link Aggregation Control Protocol (LACP) in a LAG?

It encrypts traffic sent over the aggregated links

It negotiates and maintains the membership of physical links in a LAG

It provides the load-balancing algorithm used to distribute traffic across member links

It assigns IP addresses to the aggregate interface

Which benefit does a LAG provide beyond increasing bandwidth?

It eliminates the need for Spanning Tree Protocol (STP) on all switches

It increases the maximum transmission unit (MTU) of the link

It provides redundancy by allowing traffic to continue flowing if one member link fails

It guarantees that all traffic is load-balanced evenly across all links

Which packet fields are commonly used in the hash calculation for Layer 3 load balancing across a LAG?

Source and destination IP addresses

Source and destination MAC addresses only

Link Aggregation Groups (LAG) JN0-281 Practice Questions (Page 3)

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.
