What is the primary purpose of load balancing in Junos routing?

To distribute traffic across multiple equal-cost paths to improve utilization and redundancy

To increase the reliability of the routing protocol by sending more hellos

To reduce the number of routes in the routing table

To ensure that all traffic uses the path with the lowest metric

Which benefit does load balancing provide in a Junos network?

It improves network resilience by providing alternate paths

It reduces the CPU load on the routing engine

It eliminates the need for routing protocols

It guarantees that all packets arrive in order

You have configured per-flow load balancing across three equal-cost paths. You notice that traffic is not evenly distributed; one path carries significantly more traffic than the others. Which factor is most likely contributing to the imbalance?

The router is using per-packet load balancing

The next-hops have different metrics

The hash algorithm uses only the destination IP address

You are configuring load balancing on a Junos router. You have two equal-cost paths to a destination. You want to use per-flow load balancing. Which of the following configuration statements are required? (Select all that apply.)

set routing-options static route 0.0.0.0/0 next-hop 1.1.1.1

set policy-options policy-statement LB then load-balance per-flow

set routing-options forwarding-table export LB

set interfaces ge-0/0/0 unit 0 family inet address 192.0.2.1/30

A financial trading firm runs latency-sensitive TCP applications between two data centers. They have two equal-cost paths and want to use both links without causing TCP performance degradation from out-of-order packets. Which load-balancing approach should you implement?

Filter-based forwarding with per-packet

Load Balancing JN0-352 Practice Questions (Page 2)

Part of the Protocol Independent Routing domain, which makes up ~10% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–6 in this domain), expect 1–1 from this objective — we provide 14 practice questions to prepare you well beyond it.
