Salesforce Platform Developer I (PDI) Sample Questions (Q173-Q178):

NEW QUESTION # 173
A developer is asked to prevent anyone other than a user with Sales Manager profile from changing the Opportunity Status to Closed Lost if the lost reason is blank.
Which automation allows the developer to satisfy this requirement in the most efficient manner?

A. An Apex trigger on the Opportunity object
B. An approval process on the Opportunity object
C. An error condition formula on a validation rule on Opportunity
D. A record trigger flow on the Opportunity object

Answer: C

Explanation:
* Why Validation Rule?
* Validation rules are efficient for enforcing field-level conditions without requiring Apex or Flow.
* A formula can check if the user's profile is not "Sales Manager" and if the Lost Reason field is blank when Status is set to "Closed Lost".
* Why Not Other Options?
* A: Triggers are more complex and unnecessary for this simple validation.
* C: Record-triggered flows are less efficient for field validations compared to validation rules.
* D: Approval processes do not handle this type of field-level restriction.
* Validation Rule Documentation: https://help.salesforce.com/s/articleView?id=sf.

NEW QUESTION # 174
A developer must create a Lightning component that allows users to input Contact record information to create a Contact record, including a Salary c custom field.
What should the developer use, along with a lightning-record-edit-form, so that Salary__c field functions as a currency input and is only viewable and editable by users that have the correct field level permissions on Salary _c?

Answer: D

NEW QUESTION # 175
Universal Containers recently transitioned from Classic to Lightning Experience.
One of its business processes requires certain values from the Opportunity object to be sent via an HTTP REST callout to its external order management system when the user presses a custom button on the Opportunity detail page. Example values are as follows:
* Name
* Amount
* Account
Which two methods should the developer implement to fulfill the business requirement?

A. Create an after update trigger on the Opportunity object that calls a helper methodusing @Future (callout=true) to perform the HTTP REST callout.
B. Create a Remote Action on the Opportunity object that executes an Apex immediateaction to perform the HTTP REST callout whenever the Opportunity is updated.
C. Create a Lightning component quick action that performs the HTTP REST callout, anduse a Lightning Action to expose the component on the Opportunity detail page.
D. Create a custom Visualforce quick action that performs the HTTP REST callout, anduse a Visualforce quick action to expose the component on the Opportunity detail page.

Answer: C,D

Explanation:
Answers A and C are correct. After moving from Salesforce Classic to Lightning Experience, JavaScript-style custom buttons are not the preferred pattern. A Visualforce quick action can expose a Visualforce page that invokes Apex to perform the HTTP REST callout, and a Lightning component quick action can provide the same user-initiated behavior with a Lightning-native interface. Both preserve the requirement that the user presses an action on the Opportunity page before data is sent to the external order-management system. An after-update trigger is not equivalent because it runs whenever the record is updated, not specifically when the user chooses the custom button behavior. A Remote Action tied to an immediate action on update also changes the event model and can send data at the wrong time. Reference focus: Salesforce Lightning Experience alternatives for JavaScript buttons, Quick Actions, Apex callouts, and Lightning component actions. This matters on the Salesforce platform because the same logic can run from the user interface, API operations, imports, and background automation.

NEW QUESTION # 176
A developer needs to implement a custom SOAP Web Service that is used by an external Web Application. The developer chooses to include helper methods that are not used by the Web Application in the implementation of the Web Service Class.
Which code segment shows the correct declaration of the class and methods?

A. webservice class webserviceclass { private static Boolean betweenhead() {/ implementation / } webservice static String updateheader() { / implementation / } }
B. webservice class webserviceclass { private static Boolean betweenhead() {/ implementation / } global static String updateheader() { / implementation / } }
C. global class webserviceclass { private static Boolean betweenhead() { /*implementation / } global string updateheader() { / implementation / } }
D. global class webserviceclass { private static Boolean betweenhead() { / implementation*/ }

Answer: A

Explanation:
Answer C is correct. Apex integration code must use the platform-supported annotations and asynchronous patterns for the integration direction. Apex REST exposes classes through @RestResource and HTTP method annotations. SOAP web services use webservice static methods. Outbound callouts from triggers must be moved to asynchronous code or launched from user-initiated controller/component logic. 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.

C. Configure the user interface and enable both inline editing and enhanced lists.
