The DEX-450日本語 exam is the official Salesforce exam behind the Salesforce Developer certification, validating the skills measured by the Salesforce Programmatic Development using Apex and Visualforce in Lightning Experience Exam (DEX-450日本語版) credential. It sits at the Platform Developer I level of the Salesforce certification program. It also connects to Platform Developer II (PDII), Salesforce Certified Administrator, so the knowledge you build here carries over to those tracks as well.

The DEX-450日本語 exam contains 60 questions to be completed within 120 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 PremiumVCEDump 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.

The passing score for the DEX-450日本語 exam is 68%, and the official registration fee is $200 USD. Retakes are not discounted — every new attempt means paying the full fee again — so it pays to measure yourself before you book. Work through the 202 practice questions on PremiumVCEDump, sit a timed practice test, and schedule your exam only when your scores are consistently comfortable. That simple habit is the cheapest exam strategy there is.

No formal prerequisites, but recommended: 1-2 years Apex development experience, completion of Salesforce Developer Beginner and Intermediate Trailhead modules Requirements can change when Salesforce revises its certification program, so confirm the current eligibility rules on the official exam page before you register.
