                                      Everything Candidates Ask About the Plat-Dev-301 Exam

                                      The Salesforce Certified Platform Developer II - Multiple Choice exam (exam code Plat-Dev-301) is the official Salesforce exam that leads to the Salesforce Certified Platform Developer II certification, sitting at the Professional level of the Salesforce certification track. It is also connected with Salesforce Certified Platform Developer I. If this is the credential you are working toward, the 204 practice questions at Actual4Cert map directly to its objectives.

                                      The Salesforce Certified Platform Developer II - Multiple Choice exam includes 60 questions, and you have 105 minutes to complete them. Divide the time limit by the question count and you get a tight average pace per item, so train yourself to flag time-consuming questions and return to them later instead of getting stuck. Before test day, run at least one full timed session in the Actual4Cert test engine under the same limits — the clock should never surprise you.

                                      The passing score for Salesforce Certified Platform Developer II - Multiple Choice is 65%, and the official registration fee is $200 USD. A failed attempt means paying that fee in full again, so your preparation budget deserves the same attention as your study plan. A practical rule: book your exam date only after you can finish a Actual4Cert practice test comfortably above the passing score more than once.

                                      According to Salesforce, candidates should meet the following before registering: Recommended prerequisite: Salesforce Certified Platform Developer I and practical experience building Salesforce applications with Apex and Lightning Platform..
