Salesforce Certified Platform Developer I Sample Questions (Q90-Q95):

NEW QUESTION # 90
A developer is alerted to an issue with a custom Apex trigger that is causing records to be duplicated.
What is the most appropriate debugging approach to troubleshoot the issue?

Answer: B

Explanation:
The Apex Interactive Debugger allows developers to step through code execution in real time, which is the most effective way to identify the root cause of the duplication issue.
Reference:Apex Debugging Tools
Incorrect Options:
A:Historical event logs are not specific enough for debugging triggers.
B:system.debugcan help but is less efficient than an interactive debugger.
D:Disabling the trigger disrupts the system and prevents further testing.


NEW QUESTION # 91
What are two characteristics related to formulas?
Choose 2 answers

Answer: A,D

Explanation:
Formulas are expressions that are used to calculate and display values based on the data in your records.
Formulas can be used in various contexts, such as formula fields, validation rules, workflow rules, and so on.
Some of the characteristics related to formulas are:
* Formulas are calculated at runtime and are not stored in the database. This means that every time a record is viewed or a report is run, the formula is evaluated based on the current data in the record. This ensures that the formula results are always up to date and accurate1.
* Formulas can reference values in related objects. This means that you can use formulas to access data from parent or child objects, or even from objects that are indirectly related via lookup or master-detail relationships. For example, you can use a formula field on the Opportunity object to display the account owner's name by referencing the Owner.Name field on the Account object2.
* Formulas cannot reference themselves. This means that you cannot use a formula field or variable as part of its own definition. For example, you cannot create a formula field called Total Amount that adds itself to another field. This would create a circular reference and cause an error3.
* Fields that are used in a formula field cannot be deleted or edited without editing the formula. This means that if you want to delete or change a field that is referenced by a formula field, you have to modify the formula field first to remove or update the reference. Otherwise, the formula field will become invalid and display an error.

NEW QUESTION # 92
What are two benefits of using declarative customizations over code? Choose 2 answers Choose 2 answers

Answer: A,B

Explanation:
Declarative customizations in Salesforce refer to point-and-click configurations made through the Salesforce UI, such as creating objects, fields, workflows, and processes.
Option C: Declarative customizations automatically update with each Salesforce release.
True.
Declarative features are managed by Salesforce and are automatically updated and enhanced with each new release.
Users benefit from new features without needing to modify existing configurations.
Declarative solutions are typically simpler and less complex than code-based customizations.
They are easier to manage and require less ongoing maintenance.
Changes can be made without the need for a developer.
Declarative customizations do not generate test classes.
Test classes are required for Apex code and need to be written by developers.
Option B: Declarative customizations cannot generate run-time errors.
False.
While declarative customizations reduce the likelihood of errors, they can still result in run-time errors if misconfigured.
For example, validation rules or process builders can cause errors if they conflict with other processes.
Conclusion:
The benefits of using declarative customizations over code are that they automatically update with each Salesforce release (Option C) and generally require less maintenance (Option D).
Reference:
Salesforce Release Updates
Option D: Declarative customizations generally require less maintenance.
True.
Declarative vs. Programmatic Customization
Why Other Options are Not Accurate:
Option A: Declarative customizations automatically generate test classes.
False.


NEW QUESTION # 93
An org tracks customer orders on an Order object and the items of an Order on the Line Item object. The Line Item object has a MasterDetail relationship to the order object. A developer has a requirement to calculate the order amount on an Order and the line amount on each Line item based on quantity and price.
What is the correct implementation?

Answer: D

Explanation:
The correct implementation is to implement the line amount as a numeric formula field and the order amount as a roll-up summary field. This is because formula fields can calculate values based on other fields, such as quantity and price, without requiring any code or process1. Roll-up summary fields can aggregate values from related records, such as the sum of line amounts for an order, without requiring any code or process2. This solution is the most declarative and efficient way to achieve the requirement.

* 2: Define Roll-Up Summary Fields
