Frequently Asked Questions
What is the current JNCIA-Junos exam code in 2026?
Juniper announced a JNCIA-Junos exam update on March 2, 2026. As of March 11, 2026, JN0-105 is still the active exam through April 5, 2026, and JN0-106 becomes active on April 6, 2026. The objectives remain centered on Junos OS fundamentals, CLI operation, configuration, monitoring, routing, and routing policy.
How many questions are on the JNCIA-Junos exam, and how long do you get?
Juniper lists the JNCIA-Junos exam as 65 multiple-choice questions with a 90-minute time limit. The exam is delivered in English through Pearson VUE. Plan your pacing around about 80 seconds per question, leaving a few minutes at the end for review.
What is the JNCIA-Junos passing score?
Juniper does not publicly publish a numeric passing score for JNCIA-Junos. Instead, candidates receive immediate pass or fail status after the exam. That means your study goal should be broad coverage of all seven objective domains rather than trying to reverse-engineer a target percentage.
Does Juniper publish official domain percentage weightings?
No. Juniper publicly publishes the JNCIA-Junos objective domains and detailed subtopics, but it does not publicly publish official percentage weights for those domains. The study emphasis shown on this page is an estimate based on objective breadth and hands-on importance, not an official Juniper weighting.
What topics matter most for JNCIA-Junos prep?
The highest-leverage topics are CLI workflow, candidate versus active configuration, rollback and rescue operations, user and system setup, interface basics, monitoring commands, routing tables and route preference, static routing, and routing policy or firewall filter logic. Candidates who already know general networking often lose points on Junos-specific operational behavior rather than on IPv4 or subnetting.
How long should I study for JNCIA-Junos?
Most candidates with general networking experience can prepare in about 40 to 70 hours over 3 to 6 weeks. If Junos is your first network operating system, budget extra time for CLI navigation, configuration hierarchy, commit workflow, rollback behavior, and routing policy syntax. Repeated practice with realistic command output matters more than memorizing isolated facts.
