JNCIS-ENT JN0-352: Enterprise Routing Practice Tests

This course contains the use of artificial intelligence.

A working link does not always mean a working VLAN, adjacency or route. This course helps you turn enterprise-network observations into defensible Junos configuration and troubleshooting decisions for JNCIS-ENT JN0-352, using the official Junos OS 23.1 baseline.

You will work through 330 original questions in six tests. Cases ask you to interpret VLAN membership, spanning-tree roles, security bindings, routing-table context, protocol messages, path attributes, tunnel overhead and high-availability readiness. Every option has feedback, and each question includes an overall explanation and a focused review suggestion.

What is included

• Four focused tests with 50 questions each: switching and spanning tree; Layer 2 security and independent routing; OSPF and IS-IS; BGP, tunnels and high availability.
• Two mixed mock exams with 65 questions each and a 90-minute time limit, matching the publicly stated question count and duration.
• Configuration reasoning, operational evidence, route and metric comparisons, and failure scenarios that separate control-plane health from forwarding success.
• Explanations that show why near-miss alternatives fail under the stated conditions, with official documentation links for further study.

How to use the tests

1. Complete a focused test and explain your selected answer before opening the feedback.
2. Review the missed condition: table, interface, protocol level, policy direction, route eligibility or protection boundary.
3. Attempt a mixed mock in one sitting, then investigate mistakes by topic instead of only memorizing the selected option.

The four focused tests use self-defined 75-minute limits. All six tests use an 80% training target; it is not Juniper's official passing score. Juniper lists 65 multiple-choice questions and 90 minutes for this exam, but does not publish fixed domain weights or a fixed passing percentage on the current exam page. The mixed-test topic distribution is an independent study design.

These are original learning questions, not recalled or confidential exam items. Configuration examples support syntax and decision practice; this course does not provide a hosted Junos lab or claim that every example was executed on a device. Feature availability can depend on the platform and supported release.

This independent course is not affiliated with or endorsed by Juniper Networks or HPE Networking. Certification names and marks identify the study topic. No exam-pass guarantee is offered.
