You are configuring a LAG on a Junos device. Which statement correctly describes the configuration of a LAG?

You must configure the LAG under the [edit chassis] hierarchy, and member interfaces are added using the set chassis lag command.

You must configure the LAG under the [edit interfaces] hierarchy, but member interfaces are automatically detected by the device.

You must assign the LAG a unique link aggregation group number and then add member interfaces to that group.

You must configure the LAG under the [edit protocols] hierarchy, and member interfaces are added using the set protocols lag command.

A network engineer is designing a redundant connection between two switches. The requirement is to have a primary link carry all traffic, and a backup link that is used only if the primary fails. The engineer also wants to ensure that the backup link is not used for any traffic under normal conditions. Which feature should be used?

Virtual Router Redundancy Protocol (VRRP)

Spanning Tree Protocol with a blocked port

What happens to traffic when the primary link in a redundant trunk group fails?

Traffic is dropped until the primary link is restored

Traffic is sent over the management interface

Traffic is rerouted to the backup link, which becomes active

Traffic is immediately load-balanced across all remaining links

Which statement correctly describes the operation of a redundant trunk group (RTG)?

All links in the RTG are active and carry traffic simultaneously

The backup link is used for load balancing when the primary link is congested

The primary link carries all traffic, and the backup link takes over when the primary fails

The RTG uses LACP to negotiate which link is primary

What is the purpose of a redundant trunk group (RTG) on a Junos device?

To provide a redundant path for routing protocols only

To combine multiple links into a single logical link for increased bandwidth

To load-balance traffic across multiple links using a hash algorithm

To provide link redundancy by designating one link as primary and another as backup

Part of the High Availability 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 1–1 from this objective — we provide 13 practice questions to prepare you well beyond it.
