Juniper JN0-349 Exam: Everything You Wanted to Ask
The JN0-349 exam is the official Juniper exam for Juniper Enterprise Routing and Switching, Specialist (JNCIS-ENT). Passing it earns you the JNCIS-ENT credential, which sits at the Specialist level. It is also connected to JNCIA-Junos (JN0-103), JNCIP-ENT (JNP-349), JNCIE-ENT, so what you learn carries over if you plan to pursue those paths as well. Employers treat the certification as verified proof of skill, which is why structured preparation with 2Pass4sure's practice questions pays off.
The JN0-349 exam contains 65 questions, and the time limit is 90 minutes. Translate that into a pacing plan before exam day: know roughly how long you can afford per item, flag anything that stalls you, and circle back at the end instead of burning minutes. Two or three full timed sessions in 2Pass4sure's test engine will teach you that rhythm far better than untimed reading ever will.
The passing score for the JN0-349 exam is 62%, and the official registration fee is USD $200. Remember that a failed attempt means paying that fee again in full for a retake, so treat self-assessment as part of the budget: run 2Pass4sure's practice questions under timed conditions and only book your seat once your scores sit comfortably above the passing bar.
JNCIA-Junos (JN0-103) recommended but not required Eligibility details can change, so before you register, confirm the current requirements on the official exam page: https://www.juniper.net/us/en/training/certification/.

The guarantee does not apply to attempts made within the first 3 days after purchase, to products downloaded without actually sitting the exam, or to free materials and expired orders, and the candidate name must match the payer's name.
