Juniper Enterprise Routing and Switching, Specialist (JNCIS-ENT) Exam FAQ: What Candidates Ask Most
What is the Juniper JN0-348 exam?
The JN0-348 exam is the official Juniper Networks exam behind the JNCIS-ENT certification, validating the skills measured by the Juniper Enterprise Routing and Switching, Specialist (JNCIS-ENT) credential. It sits at the Specialist level of the Juniper Networks certification program. It also connects to Juniper Networks Certified Internet Specialist - Enterprise Routing and Switching (JNCIS-ENT), Juniper Networks Certified Associate - Junos (JNCIA-Junos), so the knowledge you build here carries over to those tracks as well.
How many questions are on the JN0-348 exam, and how much time do I get?
The JN0-348 exam contains 65 questions to be completed within 90 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the Getcertkey test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.
