Salesforce Platform Developer I (PDI) 認定 PDI 試験問題 (Q184-Q189):

質問 # 184
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?

A. < lightning-input-currency value= " Salary__c " > < /lightning-input-currency >
B. < lightning-input type= " number " value= " Salary__c " formatter= " currency " > < /lightning-input >
C. < lightning-formatted-number value= " Salary__c " format-style= " Currency " > < /lightning-formatted- number >
D. < lightning-input-field field-name= " Salary__c " > < /lightning-input-field >

正解：D

解説：
Answer C is correct. The Salesforce Platform favors metadata-driven design where possible and Apex or custom UI when requirements exceed declarative capability. Correct design means selecting the lowest- maintenance platform feature that satisfies security, data integrity, scalability, and user experience requirements while remaining compatible with Salesforce's multi-tenant runtime model. 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: Lightning Web Components Developer Guide, Lightning Component Reference, Aura Components Developer Guide, and Visualforce Developer 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. This matters on the Salesforce platform because the same logic can run from the user interface, API operations, imports, and background automation.

質問 # 185
Which two characteristics are true for Aura component events? Choose 2 answers

A. By default, containers can handle events thrown by components they contain.
B. Depending on the current propagation phase, calling event. Stoppropagation () may not stop the event propagation.
C. If a container component needs to handle a component event, add a includeFacets" true" attribute to its handler.
D. The event propagates to every owner in the containment hierarchy.

正解：B、D

質問 # 186
A developer must perform a complex SQL query that joins two objects in a Lightning component.
How can the Lightning component execute the query?

A. Invoke an Apex class with the method annotated as @AuraEnabled to perform thequery.
B. Use the Salesforce Streaming API to perform the SQL query.
C. Write the query in a custom Lightning web component wrapper and invoke from theLightning component.
D. Create a flow to execute the query and invoke from the Lightning component.

正解：A

解説：
Answer B is correct. Lightning Web Components use modern web standards with Salesforce-specific modules, decorators, base components, and Lightning Data Service integration. Parent components pass data down through public properties or public methods, while children communicate upward with custom events.
Apex methods imported from @salesforce/apex must be annotated correctly and wired methods must be cacheable. 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: Lightning Web Components Developer Guide, Lightning Component Reference, Aura Components Developer Guide, and Visualforce Developer 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.

質問 # 187
A Next Best Action strategy uses an Enhance element that invokes an Apex method to determine a discount level for a Contact, based on a number of factors.
What is the correct definition of the Apex method?

正解：C

質問 # 188
A developer completed modifications feature that is comprised of two elements:
* Apex trigger
* Trigger handler Apex class
What are two factors that the developer must take into account to properly deploy them to the production environment?
Choose 2 answers

A. At least one line of code must be executed for the Apex trigger.
B. Apex classes must have at least 75% code coverage org-wide.
C. All methods in the test classes must use @istest.
D. Test methods must be declared with the testMethod keyword.

正解：A、B

解説：
* 75% Code Coverage (A):To deploy Apex code to production, Salesforce requires at least 75% of the code to be covered by tests across the organization.
Reference:Apex Testing Framework
Trigger Coverage (C):Apex triggers must have at least one line of code covered by test execution to deploy.
Reference:Testing Apex Triggers
Incorrect Options:
B:Although@isTestis recommended, it is not mandatory for all methods.
D:ThetestMethodkeyword is outdated and replaced by@isTest.
