Having that I could not find any reviews or structured opinions about these certifications I found myself eager to start a topic about this subject.
My background: 4.5 years in ISP support environment (where these certifications strongly apply)
JN0-690:
Junos Troubleshooting in the NOC (JTNOC)
- What I did for this course:
Did not attend / check material
Went straight to the exam (check why on JN0-692)
I enjoyed the structure of the exam, the questions were clear and concise however I felt disappointed by its depth. Bearing in mind that you are required to have a P level for the support track initiation, this exam looks like sending you back half-way between A and S levels. If evaluation goes from one that is simply not used to troubleshooting techniques (e.g.. Someone not pursuing the E level / not in support environments) the contents are more than appropriate.
JN0-692:
Advanced Junos Service Provider Troubleshooting (AJSPT)
- What I did for this course:
Was fortunate enough to have this training taught by the contents' developer during a live training. Apart from being someone with a huge support background, you can actually see his personality allover the book. This experience lead me to skip the JTNOC contents with no hesitation. The depth of the material is definitely appropriate. The labs are comprehensive enough to lead you to required rapid resolution techniques and task break down.
Applied normal study techniques to provided books and recommended resources.
The exam was a joyful challenge. I felt hard to coop with the required average times per question due to the fact that some exhibits were very extensive and screen resolution impacts your experience. The depth of these questions is exactly what you are expected to know if the study from recommended material is taken seriously. Very positive marks for both contents and question types.
JN0-694:
Advanced Junos Enterprise Routing Troubleshooting (AJERT)
Advanced Junos Enterprise Switching Troubleshooting (AJEXT)
- What I did for this course:
Bought the materials from online store and applied normal study techniques to theory. Did not had the chance to experiment the live training but I cannot be left to think that it would be very useful to practice these materials. I was able to visualize mentioned examples since and only since I recently did the ENT bootcamp. I strongly suggest that you get to do the labs if you buy these training materials.
The exam was different from JN0-692. Having the past experience I sat the exam bearing in mind to rush on short length type of questions in order to get more attention to long exhibits. The depth of the questions was more than appropriate. They are very straight to the point and could not ask for more. Felt this exam to be more relaxed but comprehensive and broader to bear all study topics.
Looking back at these three exams I cannot recommend them enough to anyone that either wishes to get her/himself certified in proper JUNOS troubleshooting techniques.
Furthermore I would also like to emphasize that the contents are definitely appropriate to get yourself motivated and definitely more experienced towards the E level for these tracks, if that is your final goal.
I would like to recommend Juniper Certification team to try to motivate / inform people to apply towards the JN0-690 exam after completing the S level and not only after the P level is achieved.
Look forward to hear your experiences.
Cheers!
