最新的 Salesforce Developer Plat-Dev-301 免費考試真題 (Q143-Q148):

問題 #143
Given a list of Opportunity records named opportunityList, which code snippet is best for querying all Contacts of the Opportunity's Account?
A)

B)

C)

D)

A. Option C
B. Option A
C. Option D
D. Option B

答案：B

問題 #144
A developer notices the execution of all the test methods in a class takes a long time to run, due to the initial setup of all the test data that is needed to perform the tests. What should the developer do to speed up test execution?

A. Define a method that creates test data and annotate with @createData.
B. Define a method that creates test data and annotate with @testSetup.
C. Ensure proper usage of test data factory in all test methods.
D. Reduce the amount of test methods in the class.

答案：B

解題說明：
Using the @testSetup annotation to define a method that creates test data before the tests run can significantly speed up test execution by reducing the setup time for each test method in the class. This method runs once before any test method in the class and can be used by all test methods.

問題 #145
Which two best practices should the developer implement to optimize this code? Choose 2 answers

A. Use a collection for the DML statement.
B. Remove the DML statement.
C. Query the Driving-Structure_C records outside of the loop
D. Change the trigger context to after update, after insert

答案：A,C

解題說明：
To optimize the code in question, it's important to follow best practices that reduce the number of SOQL queries and DML statements within loops, as these can quickly consume governor limits and lead to inefficiencies. Option C is correct because using a collection to hold records and performing a single DML operation outside of loops reduces the number of DML operations, which is a best practice for bulkifying code in Salesforce. Option D is also correct because querying records outside of a loop prevents hitting SOQL governor limits and makes the code more efficient. Options A and B are not correct in the context provided, as there isn't enough information to determine if changing the trigger context is necessary, and removing the DML statement altogether may not be feasible if the logic requires data to be persisted.

問題 #146
A developer has a test class that creates test data before making a mock callout but now receives a 'You have uncommitted work pending. Please commit or rollback before calling out' error.
Which step should be taken to resolve the error?

A. Ensure the records are inserted before the Test.startTess() statement and the mock callout occurs after the Test. Startest().
B. Ensure both the insertion and mock callout occur after the Test.startTest().
C. Ensure both the Insertion and mock callout occur after the I==L. stoptest_().
D. Ensure the records are Inserted before the Tezt.startTest() statement and the mock callout occurs within a method annotated with @testSetup.

答案：A

解題說明：
When working with Apex tests that involve callouts, it's important to avoid the 'uncommitted work pending' error. This error typically occurs because DML operations (like inserts) are pending when a callout is attempted. Salesforce requires that all callouts are made before any DML operations in a transaction. To avoid this, the pattern is to insert the records before calling Test.startTest(), and then make the callout after this call. Test.startTest() marks the point where your actual test begins, and it resets the governor limits. By making the callout after this point, it ensures that the DML operations are committed and you are within a new execution context regarding governor limits.

問題 #147
Exhibit:

The test method above tests in Apex trigger that the developer knows will make a lot of queries when a lot of Accounts are simultaneously updated to be customers. The test method fails at the Line 20 because of too many SOQL queries. What is the correct way to fix this?

A. Replace most of the Apex Trigger with Process Builder processes to reduce the number of queries in the trigger
B. Add Test.startTest() before and Test.stopTest() after both Line 7 of the code and Line 20 of the code
C. Change the DataFactory class to create fewer Accounts so that the number of queries in the trigger is reduced
D. Add Test.startTest() before Line 18 of the code and add Test.stopTest() after line 18 of the code

答案：D
