NEW QUESTION # 156
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.
Which step should the developer take to resolve the issue and properly test the exception?
Answer: C
NEW QUESTION # 157
Universal Containers (UC) uses a custom object called Vendor. The Vendor custom object has a master-detail relationship with the standard Account object.
Based on some internal discussions, the UC administrator tried to change the master-detail relationship to a lookup relationship, but was not able to do so.
What is a possible reason that this change was not permitted?
Answer: C
Explanation:
Master-detail relationships allow roll-up summary fields to aggregate data from child records. If a roll-up summary field exists on the Account object, the relationship cannot be changed to a lookup because lookup relationships do not support roll-up fields.
Why not other options?
A: Null values in the Vendor records do not prevent the change.
C: Custom fields can have their types changed as long as dependencies like roll-up fields are not present.
D: Organization-wide defaults do not affect the ability to change relationships.

NEW QUESTION # 158
What are three ways for a developer to execute tests in an org? Choose 3.
Answer: B,C,D
NEW QUESTION # 159
A developer is working on a project to import data from an external system into Salesforce. The data contains sensitive information that should not be visible to all users in Salesforce.
What should the developer do to ensure that the data is secure?
Answer: D
Explanation:
Answer D is correct. Salesforce security is layered. Record access is controlled by sharing, object permissions control CRUD, and field-level security controls field visibility and editability. Apex can run with or without sharing, but developers must explicitly enforce CRUD and field permissions when returning data to custom UI. Lightning Data Service and lightning-input-field handle much of this automatically. 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.
NEW QUESTION # 160
A developer writes a trigger on the Account object on the before update event that increments a count field. A workflow rule also increments the count field every time that an Account is created or updated. The field update in the workflow rule is configured to not re-evaluate workflow rules.
What is the value of the count field if an Account is inserted with an initial value of zero, assuming no other automation logic is implemented on the Account?
Answer: D
