Salesforce Platform Developer I (PDI) 認定 PDI 試験問題 (Q48-Q53):

質問 # 48
Universal Containers (UC) processes orders in Salesforce in a custom object, order_c.
They also allow sales reps to upload CSV files with thousands of orders at a time.
A developer is tasked with integrating orders placed in Salesforce with UC ' s enterprise resource planning (ERP) system.
After the status for an order_c is first set to ' Placed ' , the order information must be sent to a REST endpoint in the ERP system that can process one order at a time.
What should the developer implement to accomplish this?

A. Callout from a queueable class called from a trigger
B. Callout from a batchable class called from a scheduled job
C. Callout from an instantaneous method called from a trigger
D. Flow with a callout from an invocable method

正解：A

解説：
Answer A is correct. Salesforce enforces governor limits so code from many tenants can share platform resources safely. Synchronous Apex has strict limits for SOQL, DML, CPU, heap, and rows processed.
Asynchronous patterns such as Batch Apex, Queueable Apex, and future methods separate work into transactions and often provide different limit profiles, but they still require bulk-safe code. 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.

質問 # 49
Refer to the following code that runs in an Execute Anonymous block:

A. In an environment where the full result set is returned, what is a possible outcome of this code?
B. The transaction will succeed and the first ten thousand records will be committed to the database.
C. The total number of records processed as a result of DML statements will be exceeded.
D. The total number of DML statements will be exceeded.

正解：A

質問 # 50
Given the following trigger implementation:
trigger leadTrigger on Lead (before update){
final ID BUSINESS_RECORDTYPEID = '012500000009Qad';
for(Lead thisLead : Trigger.new){
if(thisLead.Company != null &&thisLead.RecordTypeId != BUSINESS_RECORDTYPEID){ thisLead.RecordTypeId = BUSINESS_RECORDTYPEID;
}
}
}
The developer receives deployment errors every time a deployment is attempted from Sandbox to Production.
What should thedeveloper do to ensure a successful deployment?

A. Ensure BUSINESS_RECORDTYPEID is retrieved using Schema.Describe calls.
B. Ensure a record type with an ID of BUSINESS_RECORDTYPEID exists on Production prior to deployment.
C. Ensure the deployment is validated by a System Admin user on Production.
D. Ensure BUSINESS_RECORDTYPEIDis pushed as part of the deployment components.

正解：B
