A random approach won’t work here. Let’s break it down:
Step 1: Learn the Exam Structure
Before diving into your study materials, it’s crucial to understand how the JN0-105 exam is structured. Knowing what to expect allows you to align your preparation accordingly and manage your time effectively on exam day.
Exam Format
The JN0-105 exam consists entirely of multiple-choice questions. You may encounter both single-answer and multiple-answer formats, but you won’t see simulations or performance-based labs.

Time Limit
You’ll have 90 minutes to complete the exam. This requires efficient pacing, especially if you’re aiming to review your answers.
Passing Score
Juniper does not publicly disclose the exact passing score. However, most candidates estimate that scoring around 65% to 70% is necessary to pass. Aiming for 80% in your practice tests is advisable.
Language Availability
The exam is available in English and Japanese.
Exam Cost
The cost of the JN0-105 exam is typically USD 200. However, prices may vary depending on your region. You can verify current pricing and schedule your exam on the official Pearson VUE Juniper page.
Step 2: Study Using Official Materials
Authentic resources from Juniper and trusted platforms ensure you're learning what is truly relevant to the exam.
Juniper Learning Portal
Juniper provides self-paced online courses tailored for the JNCIA-Junos certification. These modules cover networking fundamentals, Junos OS basics, configuration, and troubleshooting.
Junos OS Documentation
Refer to the official Junos OS documentation available on Juniper’s website. This is especially helpful for understanding configuration examples, syntax, and real-world application of Junos features.

Step 4: Take JN0-105 Practice Tests
Practice tests are the most powerful preparation tool. They help you assess your readiness and simulate the pressure of a timed exam.
Why They Matter

- They enhance retention through repetition
Where to Find Quality Practice Tests

How Often Should You Take Them?
Begin with one full-length test to benchmark your current level. As you progress, take two to three practice tests per week. Continue until you consistently score 85 percent or higher.

Create a Revision Plan
