The JN0-348 exam is the official Juniper exam behind Juniper Enterprise Routing and Switching, Specialist (JNCIS-ENT) — passing it earns you the JNCIS-ENT (Enterprise Routing and Switching, Specialist) certification, a credential positioned at the Specialist level. It is built for candidates who want to validate the skills measured by Juniper Enterprise Routing and Switching, Specialist (JNCIS-ENT). Depending on your track, the exam is also linked to the JNCIA-Junos, JNCIP-ENT and JNCIE-ENT certifications, so one pass can move you toward more than one Juniper credential.

The JN0-348 exam presents 65 questions to be completed within 90 minutes. That pace leaves little room for second-guessing: read each question carefully on the first pass, flag the ones you want to revisit, and keep moving instead of stalling on a single item. Before exam day, run at least one full timed session in the TestSimulate desktop or online test engine with a comparable question load — a steady rhythm under the clock is a trainable skill, and it is often what separates a pass from a near miss.

To pass the JN0-348 exam you need Variable scaled score (typically ~65-70%), and the official registration fee is $200 USD. Keep in mind that a failed attempt means paying that fee again in full — retakes are not discounted. Given the cost, self-test before you book: if you can score comfortably above the passing mark on two or three consecutive timed TestSimulate practice tests, your budget is far better spent on the exam itself than on a retake.

Recommended prerequisite: JNCIA-Junos certification (JN0-104 or equivalent knowledge) Because Juniper revises its certification programs from time to time, treat this as a starting point rather than the final word. Confirm the current eligibility requirements on the official Juniper exam page before you register.
