Get Certified: Proven Methods to Pass the Salesforce CRT-450 Exam

When using the @InvocableMethod annotation in Apex, there are specific considerations to keep in mind:

Option A: Only one method using the @InvocableMethod annotation can be defined per Apex class.

True.

Explanation:

An Apex class can contain only one method annotated with @InvocableMethod.

This ensures that when the class is invoked from a flow or process, there is no ambiguity about which method to execute.

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.

Explanation:

// Get describe result for Opportunity

Schema.DescribeSObjectResult oppDescribe = Opportunity.SObjectType.getDescribe();

// Get list of RecordTypeInfo

List 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;

}

}

To test the trigger with 200 account records with unique names using the least amount of code:

Option A: Use Test.loadData to populate data in your test methods.

Explanation: Test.loadData allows you to load test data from a static resource (CSV file) into your test method. This approach minimizes code since you don't have to write code to create each record.

To override the Account's standard Edit button in Lightning Experience:

Option A: Lightning component

Explanation: In Lightning Experience, you can override standard buttons with Lightning components by implementing the appropriate interface.

Implementation:

The Lightning component must implement lightning:actionOverride interface.

<aura:component implements="lightning:actionOverride, force:hasRecordId" access="global">

</aura:component>

Scenario:

Universal Containers (UC) wants to allow multiple Accounts to share a default pickup address.

They have created a custom object called Global Address.

Requirement:

Create an efficient model to link multiple Accounts to a single Global Address.

Solution:

To associate multiple Accounts with a single Global Address, we need to create a lookup relationship from Account to Global Address.

Option D: Add a lookup field on the Account object to the Global Address object.

Correct Approach.

Explanation:

Adding a Lookup Field on the Account object that references the Global Address object allows multiple Accounts to reference the same Global Address.

This setup models a many-to-one relationship:

Many Accounts can have the same Global Address as their pickup address.

Benefits:

Data Normalization: Reduces data redundancy by storing the address once.

Ease of Maintenance: Updating the Global Address updates it for all associated Accounts.

When designing a new application on the Salesforce platform that needs to support multiple tenants effectively (i.e., multiple customers or users), the developer should consider the Model-View-Controller (MVC) framework.

Option B: Model-View-Controller (MVC)

Correct Design Framework.

Explanation:

MVC is a software architectural pattern for implementing user interfaces.

Model: Represents the data and business logic.

View: Represents the presentation layer.

Controller: Handles user input and interactions.

Salesforce's platform follows the MVC pattern, which helps in separating concerns, ensuring scalability, and maintainability.

Option C: Developer Sandbox

Correct Answer.

Explanation:

Developer Sandboxes are intended for coding and testing by a single developer.

They copy all application and configuration information from production, ensuring the same metadata.

Each developer can work in their own isolated environment.

Declarative customizations in Salesforce refer to point-and-click configurations made through the Salesforce UI, such as creating objects, fields, workflows, and processes.

Option C: Declarative customizations automatically update with each Salesforce release.

True.

Explanation:

Declarative features are managed by Salesforce and are automatically updated and enhanced with each new release.

Users benefit from new features without needing to modify existing configurations.

When updating a record of a junction object in Salesforce (an object used to create a many-to-many relationship), you must have the appropriate permissions.

Required Permissions:

Read/Write access on the junction object: To update the junction object record itself.

Read/Write access on both master (parent) records: Because the junction object is in two master-detail relationships, and its security settings are controlled by the parent records.

Given the options:

Option A: Read/Write access on the primary relationship

Option B: Read/Write access on the secondary relationship

These options correspond to having Read/Write access on both parent objects.

Supporting References:

Master-Detail Relationships:

Permissions Inheritance: The detail (junction) record inherits sharing and security settings from the master (parent) records.

Updating Records: To update a detail record, users must have Read/Write access to both the detail record and its parent records.
