Salesforce CRT-450 - Salesforce Certified Platform Developer 1 (SP25)

The code snippet in question creates and inserts an account namedMyAccountand then initializes a loop to add additional accounts.

The loop runs fromx = 1and continues adding accounts untilx < 10.

Since the conditionx++is post-increment, the loop runs exactly 10 times, creating and adding 10 new accounts to thenewAccountslist.

At the end, theinsertDML statement persists these 10 new accounts, along with the already existing account (MyAccount).

Total accounts in the org:

Existing accounts = 5

New accounts added = 10

Total = 15

Why Usefinal?

Thefinalkeyword ensures that a variable's value can only be assigned once.

Option B: Assigning the value in the constructor is valid as it allows for flexibility when creating class instances.

Option C: Assigning the value directly when declaring the variable is also valid for constants.

Why Not Other Options?

A: Static variables can have their values reassigned unless marked as final.

D: Static variables cannot be assigned within a class constructor.

Roll-Up Summary Field:

Since the relationship between Order and Order Line Item is aMaster-Detail, a Roll-Up Summary field can be used on the Order object.

The MAX function in a Roll-Up Summary field calculates the latest date (the maximum value) among all the availability dates on the Order Line Items.

Why MAX Roll-Up Summary Field Works:

The latest availability date among the Order Line Items will determine when the entire Order can be shipped.

Why Not Other Options?

AandB: There is no such formula called "LATEST" or "CEILING" applicable to date fields.

C: A COUNT Roll-Up Summary is irrelevant for calculating dates.

The Lightning Out library allows a Lightning Web Component to be embedded in a Visualforce page. This approach is the most suitable to make the LWC accessible in Salesforce Classic.

The Apex Interactive Debugger allows developers to step through code execution in real time, which is the most effective way to identify the root cause of the duplication issue.

In the provided code snippet, the classmyClassdoes not specify a sharing declaration (with sharingorwithout sharing). In Salesforce, when a class does not explicitly declare its sharing context, it defaults towithout sharing. This means sharing rules are not enforced.

Why Use Static Resources andTest.loadData?

C: Static resources allow you to define reusable test data (e.g., in a CSV file).

D:Test.loadDatasimplifies loading bulk test data into test classes from static resources.

Why Not Other Options?

A: Using@isTest(seeAllData=true)violates test isolation principles and is discouraged.

B:@isTest(isParallel=true)is used for parallel execution, not for creating test data.

Option B: To update a junction object, the user needsRead/Writeaccess to the primary relationship object.

Option C: The user must also haveRead/Writeaccess on the junction object itself.

Junction Objects Documentation

This method allows the developer to retrieve all available record types and identify the default record type for the current user by checking theisDefaultRecordTypeMapping()attribute.

Example:

Schema.DescribeSObjectResult describeResult = Opportunity.sObjectType.getDescribe();

for (Schema.RecordTypeInfo recordType : describeResult.getRecordTypeInfos()) {

if (recordType.isDefaultRecordTypeMapping()) {

System.debug('Default Record Type: ' + recordType.getName());

}

}

Scratch orgs are temporary, source-driven Salesforce environments used for development and testing. They allow developers to:

Work on independent features without interfering with each other's configurations.

Utilize a source-driven development model for CI/CD pipelines.
