Salesforce Platform Developer I (PDI) Sample Questions (Q171-Q176):

NEW QUESTION # 173
A developer wrote a unit test to confirm that a custom exception works properly in a custom controller, but the test failed due to an exception being thrown. What step should the developer take to resolve the issue and properly test the exception?

Answer: D


NEW QUESTION # 174
Which two actions may cause triggers to fire?

Answer: A,D

Explanation:
Answers A, D are correct. Apex triggers run as part of the Salesforce save transaction and must be designed around the order of execution, valid context variables, recursion risk, and bulk processing. Correct trigger design keeps logic in handlers, avoids SOQL and DML inside record loops, uses addError() when validation must block the transaction, and expects declarative automation to participate in the same transaction. The other options either use the wrong platform feature, apply at the wrong layer, or ignore a key Salesforce constraint. For Platform Developer I, the important point is not just syntax; it is choosing the feature that aligns with transaction behavior, security enforcement, maintainability, and supported metadata capabilities.
Reference focus: Salesforce Apex Developer Guide, SOQL and SOSL Reference, Flow Builder Help, and Apex Reference Guide. This distinction is important in production orgs because small design mistakes can create deployment failures, runtime exceptions, data-quality defects, or user-visible security gaps once automation is executed in bulk or from multiple entry points.
