The CRT-450日本語 exam is the official Salesforce exam for Salesforce Certified Platform Developer I (CRT-450日本語版). Passing it earns you the Salesforce Certified Platform Developer I credential, which sits at the Professional level. It is also connected to Salesforce Certified Platform App Builder, Salesforce Certified Platform Developer II, 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 CRT-450日本語 exam contains 60 questions, and the time limit is 105 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 CRT-450日本語 exam is 68%, and the official registration fee is 200 USD. 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.
