                                      Your Salesforce Certified Platform Developer II - Multiple Choice Questions, Answered

                                      Salesforce Certified Platform Developer II - Multiple Choice is an official Salesforce exam, registered under the code Plat-Dev-301. A passing score earns you the Salesforce Certified Platform Developer II certification, positioned at the Professional level. The credential also connects to Salesforce Certified Platform Developer I, so it can anchor a broader certification path. Because Salesforce designs its exams around real job tasks, holding this certification signals practical skill rather than memorized theory.

                                      Candidates face 60 questions inside a 105 minutes window on the Salesforce Certified Platform Developer II - Multiple Choice exam. That ratio leaves little slack, which is why pacing deserves as much practice as the content itself. Learn to budget your minutes, park stubborn questions instead of wrestling them, and rehearse under a real clock: a few timed runs in the Exams4sures test engine will make the official time limit feel routine rather than threatening.

                                      The passing bar for Salesforce Certified Platform Developer II - Multiple Choice is set at 65%, and registering for the exam officially costs $200 USD. There is no reduced price for a second try: fail, and you pay $200 USD in full again. That makes honest self-testing the cheapest insurance available, so hold off on booking until your Exams4sures practice scores sit clearly above the passing line, attempt after attempt.

                                      Recommended prerequisite: Salesforce Certified Platform Developer I and practical experience building Salesforce applications with Apex and Lightning Platform.

                                      Salesforce Certified Platform Developer II - Multiple Choice Sample Questions:

                                      A developer is debugging an Apex-based order creation process that has a requirement to have three savepoints, SP1, SP2, and 5P3 {created in order), before the final execution of the process.
                                      During the final execution process, the developer has a routine to roll back to SP1 for a given condition. Once the condition is fixed, the code then calls 2 roll back to SP3 to continue with final execution. However, when the roll back to SP3 is called, a Funtime error occurs.
                                      Why does the developer receive a runtime error?

                                      • A. SP3 became invalid when SP1 was rolled back.
                                      • B. The developer used too many savepoints in one trigger session.
                                      • C. The developer should have called SF2 before calling SP3.
                                      • D. The developer has too many DML statements between the savepoints.

                                      A developer notices the execution of all the test methods in a class takes a long time to run, due to the initial setup of all the test data that is needed to perform the tests. What should the developer do to speed up test execution?
