質問 # 113
A developer is creating a page that allows users to create multiple Opportunities. The developer is asked to verify the current user's default Opportunity record type, and set certain default values based on the record type before inserting the record.
How can the developer find the current user's default record type?

A. Use Opportunity.SObjectType.gethescribe () .getRaecordlypaInsos () to get a list of record types, and iterate through them until 2sDefaultRecordTypeMapping () is true.
B. Query the Profile where the ID equals uzexInfo.getProfilelD () and then use the profile.Cpportunity.gesDefaultRecordTyp= () method.
C. Use the Schema.userInfo.Cpportunity.getlefaultRecordIype () method.
D. Create the opportunity and check the opportunity. recordTyp=, which will have the record ID of the current user's default record type, before inserting.

正解：A

解説：
To find the current user's default record type for Opportunity, the developer can use the DescribeSObjectResult and RecordTypeInfo classes.
Option A: Use Opportunity.SObjectType.getDescribe().getRecordTypeInfos() to get a list of record types, and iterate through them until isDefaultRecordTypeMapping() is true.
Correct Approach.
// Get describe result for Opportunity
Schema.DescribeSObjectResult oppDescribe = Opportunity.SObjectType.getDescribe();
// Get list of RecordTypeInfo
List<Schema.RecordTypeInfo> recordTypeInfos = oppDescribe.getRecordTypeInfos();
// Iterate through RecordTypeInfo to find the default one
Id defaultRecordTypeId;
for (Schema.RecordTypeInfo rtInfo : recordTypeInfos) {
if (rtInfo.isAvailable() && rtInfo.isDefaultRecordTypeMapping()) {
defaultRecordTypeId = rtInfo.getRecordTypeId();
break;
}
}
Reference:
Options Not Applicable:
Option B and C: Methods mentioned do not exist in the API.
Option D: Create the Opportunity and check the Opportunity.RecordTypeId before inserting.
The RecordTypeId is not automatically populated before inserting.
Conclusion:
To find the current user's default Opportunity record type, the developer should use Option A.

(Full question statement)
Which statement generates a list ofLeadsandContactsthat have a field containing the phrase "ACME"?

A. List<SObject> searchList = [FIND '*ACME*' IN FIELDS RETURNING Contact, Lead];
B. List<List<SObject>> searchList = [FIND '*ACME*' IN ALL FIELDS RETURNING Contact, Lead];
C. List<List<SObject>> searchList = [SELECT Name, Id FROM Contact, Lead WHERE Name LIKE '% ACME%'];
D. List<SObject> searchList = [find 'acme' in all fields returning Contact, Lead];

正解：B

解説：
C (Correct):This is the correctSOSL (Salesforce Object Search Language)syntax. It performs a full-text search across multiple objects and fields.
The format FIND '*ACME*' IN ALL FIELDS RETURNING Contact, Lead is thestandard and correctapproach for cross-object keyword searches.
Incorrect options:
A:Incorrect syntax; needs ALL FIELDS or NAME FIELDS, and proper result typing.
B:SOQL does not support searching across multiple objects in a single query.
D:Incorrect casing and structure; missing proper list handling.
Reference:Apex Developer Guide - SOSL Syntax
This relates toDeveloper Fundamentals (23%), specificallySOSL vs. SOQL use cases and syntax.

質問 # 121
Universal Container(UC) wants to lower its shipping cost while making the shipping process more efficient.
The Distribution Officer advises UC to implement global addresses to allow multiple Accounts to share a default pickup address. The Developer is tasked to create the supporting object and relationship for this business requirement and uses the Setup Menu to create a custom object called "Global Address". Which field should the developer ad to create the most efficient model that supports the business need?

A. Add a Master-Detail field on the Account object to the Global Address object
B. Add a Lookup field on the Global Address object to the Account object
C. Add a Master-Detail field on the Global Address object to the Account object.
D. Add a Lookup field on the Account object to the Global Address object.

正解：D

解説：
A lookup field creates a relationship that links one object to another object. The relationship field allows users to click a lookup icon to select a value from a popup list. The other object is the source of the values in the list1. In this case, the developer should add a lookup field on the Account object to the Global Address object, so that multiple Accounts can share the same Global Address as their default pickup address. This way, the Global Address object can store the common address information for different Accounts, and the Account object can reference the Global Address object via the lookup field. A master-detail field creates a parent-child relationship between two objects, where the master object controls certain behaviors of the detail object. The detail object inherits the sharing and security settings of its master object2. In this case, a master-detail field is not suitable, because the Global Address object should not be dependent on the Account object, or vice versa.
The Global Address object should be able to exist independently of the Account object, and the Account object should be able to have multiple Global Address records associated with it. References:

質問 # 124
Consider the following code snippet:
As part of the deployment cycle, a developer creates the following test class:
When the test class runs, the assertion fails.
Which change should the developer implement in the Apex test method to ensure the test method executes successfully?

A. Query the Administrator use into memory and enclose lines 15 and 16 within the system,runAs (use); method.
B. Add @Istest% seeAllDataTrue; to line 12 and enclose lines 15 and 16 within Test .set(Test); and test ste-ptest();.
C. Add System, runAs (Use; to line 14 and enclose line 15 within Test, startTest); and Test ().
D. Query the Standard User into memory and enclose lines 15 and 16 within the system ,runAs; method.

正解：D

解説：
The test class is failing because the records are being inserted with the default user context, which may not have the necessary sharing or profile permissions. Wrapping the insert operations within aSystem.runAsblock using aStandard Userensures the operations are executed with the correct context, simulating real-world behavior.
Reference:Testing with System.runAs

質問 # 125
When the code executes, a DML exception is thrown.
How should a developer modify the code to ensure exceptions are handled gracefully?

A. Remove null items from the list of Accounts.
B. Implement the upset DML statement.
C. Implement Change Data Capture.
D. Implement a try/catch block for the DML.

正解：D

解説：
Why a try/catch block is required:
In Salesforce, DML operations such as insert, update, delete, and upsert can throw exceptions due to issues like validation rule violations, field constraints, or sharing rule restrictions.
Using a try/catch block ensures that these exceptions are caught and handled gracefully, preventing the entire transaction from failing.
How to modify the code:
The update statement in the code can be wrapped in a try/catch block to catch and handle any exceptions that occur. For example:
apex
Copy code
public static void insertAccounts(List<Account> theseAccounts) {
try {
for (Account thisAccount : theseAccounts) {
if (thisAccount.website == null) {
thisAccount.website = 'https://www.demo.com';
}
}
update theseAccounts;
} catch (DmlException e) {
System.debug('DML Exception: ' + e.getMessage());
}
}
Why not the other options?
A . Implement the upsert DML statement:
upsert is used to either insert or update records based on an external ID or primary key. It does not inherently handle exceptions.
B . Implement Change Data Capture:
Change Data Capture (CDC) is used for tracking changes to data in real time and is unrelated to handling DML exceptions.
D . Remove null items from the list of Accounts:
While cleaning the input data is a good practice, it does not address the need for exception handling during DML operations.

D. Use a change set to deploy the Apex code and Lightning Components.

正解：D

解説：
Why Change Sets?

Why Not Other Options?
A: The Force.com IDE is deprecated.
B: The Ant Migration Tool is more suitable for complex deployments but not necessary for standard Sandbox- to-Production migration.
D: Salesforce CLI is effective for deployment but requires scripting expertise, making Change Sets easier for most users.
