NEW QUESTION # 170
A developer created a trigger on a custom object. This custom object also has some dependent pick lists.
According to the order of execution rules, which step happens first?
Answer: C
Explanation:
The first step in the Salesforce order of execution:
Option D: The original record is loaded from the database.
This is Step 1 in the order of execution.
Why Not Other Options:
Option A: Overwriting old values happens after loading the record.
Option B: JavaScript validation occurs on the client side before server processing.
Option C: System validation for field lengths happens after loading the record.
Reference:
Order of Execution:
"1. Loads the original record from the database or initializes the record for an upsert statement."

NEW QUESTION # 171
Managers at Universal Containers want to ensure that only decommissioned containers are able to be deleted in the system. To meet the business requirement a Salesforce developer adds "Decommissioned" as a picklist value for the Status _c custom field within the Container _c object.
Which two approaches could a developer use to enforce only Container records with a status of
"Decommissioned" can be deleted?
Choose 2 answers
Answer: B,C
Explanation:
* Apex Trigger (Option B):
* An Apex trigger can be written on theContainer__cobject to prevent deletion unless theStatus__cfield value is "Decommissioned".
* This allows custom logic to be executed during the deletion process.
:Apex Triggers Documentation
Validation Rule (Option D):
A validation rule is typically used to enforce conditions during record creation or update. However, it cannot directly restrict deletions.
To ensure deletion restriction, an Apex trigger is more effective.
Not Suitable:
Option A(Before record-triggered flow): Flows triggered "before delete" are not available.
Option C(After record-triggered flow): These occur after a record is deleted, so they cannot prevent the deletion process.
NEW QUESTION # 172
A developer created a trigger on the Account object and wants to test if the trigger is properly bulkified. The developer team decided that the trigger should be tested with
200 account records with unique names.
What two things should be done to create the test data within the unit test with the least amount of code?
Answer: B,D
Explanation:
Answers A, C are correct. Salesforce delivery depends on repeatable testing and controlled deployment. Apex tests create isolated data, validate behavior, and supply code coverage for production deployment. Salesforce CLI, scratch orgs, sandboxes, debug logs, trace flags, and Apex Jobs give developers the tooling needed to build, test, diagnose, and release changes across environments. 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, Salesforce CLI Developer Guide, Tooling API documentation, and Salesforce Help deployment guidance. 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.
