質問 # 57
Universal Containers has an Apex trigger on Account that creates an Account Plan record when an Account is marked as a Customer. Recently a workflow rule was added so that whenever an Account is marked as a Customer, a 'Customer Since' date field is updated with today's date.
Since the addition of the workflow rule, two Account Plan records are created whenever the Account is marked as a Customer.
What might cause this to happen?

• A. The Apex trigger does not use a static variable to ensure it only fires once.
• B. The workflow rule is configured to evaluate when a record is created and every time it is edited.
• C. The Apex trigger is not bulk safe and calls insert inside of a for loop.
• D. The workflow rule field update is marked as 'Re-evaluate Workflow Rules After Field Change."

正解：A

質問 # 58
A developer has a Visualforce page that automatically assigns ewnership of an Account to a queue upon save. The page appears to correctly assign ownership, but an assertion validating the correct ownership fails.

• B. The test class does not use the seeallData=true= annotation.
• C. The test class does not use the Bulk API for loading test data.
• D. The test class does not implement the Queueable interface.

正解：A

質問 # 59
A developer has working business logic code, but sees the following error in the test class:
You have uncommitted work pending. Please commit
or rollback before calling out.
What is a possible solution?

• A. Use mast. T=RunningTes={} before making the callout to bypass it in test execution,
• B. Rewrite the business logic and test classes with @Testvisible set on the callout.
• C. Call support for help with the target endpoint, as It is likely an external code error.
• D. Set seeAllData to true the top of the test class, since the code does not fall in practice.

正解：A

解説：
The solution to the error is to use Test.setMock() before making the callout to bypass it in test execution. The Test.setMock() method allows the developer to specify a mock response for an HTTP callout or a web service callout, and avoid sending a real request to an external service. This way, the developer can test the callout logic without actually making the callout, and avoid the error of having uncommitted work pending. The developer should create a class that implements the HttpCalloutMock interface or the WebServiceMock interface, and define the mock response in the respond() method. Then, the developer should use the Test.setMock() method to pass the mock class and the mock response as parameters, before calling the method that makes the callout. Calling support for help with the target endpoint, as it is likely an external code error, will not help, as the error is not caused by the external service, but by the test execution. Setting seeAllData to true at the top of the test class, since the code does not follow best practice, will not help, as it will only allow the test to access the org data, but it will not bypass the callout. Rewriting the business logic and test classes with @testVisible set on the callout will not help, as it will only make the callout accessible to the test class, but it will not bypass the callout.

質問 # 67
A developer created the following test method:

The developer org has five accounts where the name starts with "Test". The developer executes this test in the Developer Console.
After the test code runs, which statement is true?

• A. There will be no accounts where the name starts with "Test".
• B. The test will fail.
• C. There will be five accounts where the name starts with "Test".
• D. There will be six accounts where the name starts with "Test".

正解：C

解説：
Based on the test method code, the statement that is true after the test code runs is that there will be five accounts where the name starts with "Test". This is because the test method is running in API version 24.0 or later, which means that it can't access pre-existing org data by default, and can only access data that it creates. Therefore, the first query that retrieves the accounts where the name starts with "Test" will return an empty list, as there are no such accounts in the test context. The test method then inserts a new account with the name "Test1", which will be the only account that the test method can access. The second query that retrieves the accounts where the name starts with "Test" will return a list with one account, which is the account that was just inserted. The test method then asserts that the size of the list is equal to 1, which will pass. The test will not fail, as there is no assertion error or exception. There will not be no accounts where the name starts with "Test", as there is one account that was inserted by the test method. There will not be six accounts where the name starts with "Test", as the test method can't access the five accounts that exist in the org data.

質問 # 74
Universal Containers uses Big Objects to store almost a billion customer transactions called customer_Transaction_ b.
These are the fields on customer Transaction b:

The following fields have been identified as Index Fields for the Customexr_Transaction__b object: Account__g, Program__c, and Transaction Date_ co.
Which SOQL query is valid on the customer_Transaction_b Big Object?

• A.
• B.

正解：B

解説：
Option A is the valid SOQL query on the customer_Transaction_b Big Object. Option A uses the index fields of the Big Object, which are Account__c, Program__c, and Transaction_Date__c, to filter the records. The query also uses the = operator to match the exact values of the index fields, which is required for Big Object queries. The query also uses the SELECT Id, Account__c, Program__c, Transaction_Date__c clause to return only the index fields of the Big Object, which is more efficient than returning all the fields. The query also uses the LIMIT 1000 clause to limit the number of records returned to 1000, which is the maximum limit for Big Object queries. Reference: [SOQL for Big Objects], [Big Object Indexes]
