My JNCIE journey from written JNCIS-SP JN0-664 to Lab preparations 

JNCIE l Cover

Hi, how are you guys doing? I am your trainer from inner Mongolia, and today I shall share my recent experience with the JNCIE-Service provider. My name is James Chiu. I’m a JNCIE service provider, a JNCIE for enterprise environments, and a CCIE. Today I want to talk about how to study for the JNCIE.

What is a JNCIE?

JNCIE is an acronym that means “Juniper Network Certified Internet Expert” basically, it’s a top-level certification that is the highest level of accreditation in public networks or a networking professional. So, in all expert level tracks, there’s always a certification hierarchy like beginner level is associates, specialist professional, and expert. Everybody wants to get to expert because it’s the most sought-after top-tier certification. So, there’s a hierarchy in juniper networks, the expert level is the JNCIE, and that means that you’re able to configure network troubleshooting,

A network manager’s network right is building a network from scratch. When you pass the exam, they give you a special certificate, so you’re among the few people with that special and unique number.

Comparison between JNCIE & other written Exams:

A JNCIE is an expert-level certification like the CCIE. JNCIE is it’s a CCIE level exam certification and also a Nokia service rather than an ex-architect certification level as well. Hence, the JNCI is different from other written examinations. The difference between a JNCIE and other written examinations is that the other examinations are MCQ questions, while the JNCIE is a lab exam.

The juniper hierarchy has a JNCIA, which is an associate-level exam. It is entry-level, like Cisco’s CCNA, and Juniper has a JNCIS specialist level. They also have a JNCIP, which is all written exams. So, for the written exams, you go to an exam centre and answer multiple choice questions correctly, so those are the written level exams, but the JNCIE is different- it’s the practical lab exam. For this sort of lab exam, I went to California to sit for the exam. I am configuring a lab topology and building a network; you’re doing it fully hands-on.

The JNCIE exam is the highest level of certification in Juniper’s certification program and requires a lab-based exam where candidates must configure and troubleshoot complex networks using Juniper’s technologies. It is considered an expert-level certification and requires a JNCIP certification as a prerequisite.

All Juniper exams are valid for three years, except for JNCIE exams which are useful for two years. After the validity period, candidates must recertify to maintain their certification status.

How to Prepare for the JNCIS-SP Exam: Study Plan


If you plan to take the JNCIS-SP exam, having a solid study plan can make all the difference in passing or studying for the expert-level exam. You can use different approaches to prepare, but boot camps and self-study are the most popular.

Option 1: Boot Camp

The fastestway to prepare for the JNCIS-SP exam is by taking a boot camp. This technique is a unique online or instructor-led training offered by different vendors in different ways. At 591Lab, for example, the JNCIE-SP boot camp techniques are an up-to-date, real lab mock examination that will give you an idea of what the actual exam could look like.

During the one-week hardcore training, an instructor will teach you everything you need to know, and they’ll give you labs to practice. After the boot camp, you’ll have a lab session to practice with trainers. This process is a great way to consolidate your knowledge and prepare for the exam day.

However, boot camps are expensive, so it depends on your budget. If you’re lucky enough to have your company sponsor your boot camp at 591LAB or any other vendor, that’s awesome. But if you’re paying for it yourself, be prepared to spend much money.

Option 2: Self-Study

Another approach is self-study. This method depends on your pace and how fast you are. It can be advantageous if you’re disciplined and stick to a schedule. However, it can also have some disadvantages. Without a structure, you may get distracted or lose focus.

The Juniper self-study bundle is an excellent resource for those who prefer to study independently. It’s like a workbook that teaches you everything about getting a JNCIE. The workbook covers all the protocols and sections you need to know for the exam. It also includes a lab section to practice your learning in a real-world scenario.

The self-study bundle has 12 lab sessions, a great way to ensure you’re fully prepared for the exam. It gives you a question, a topology, and a task, so you can practice applying the solutions to different scenarios.


In conclusion, becoming a JNCIE (Juniper Networks Certified Internet Expert) is challenging and rewarding. Starting with the written JNCIS-SP JN0-664 exam and progressing to lab preparations requires a lot of dedication, hard work, and commitment.

The written exam tests your theoretical knowledge of Juniper Networks technologies. In contrast, the lab exam requires you to demonstrate your practical skills and ability to configure and troubleshoot complex network scenarios.

Staying focused, setting achievable goals, and continuously improving your skills and knowledge are essential throughout the journey. It’s also crucial to seek support and guidance from experienced professionals, join study groups and forums, and utilize resources such as practice labs and study materials.

Becoming a JNCIE is a testament to your expertise in Juniper Networks technologies and opens up a world of opportunities and recognition within the industry. So, stay committed and persevere in your journey toward becoming a JNCIE, and the rewards will be worth the effort.
