PDI Exam Dumps - Salesforce Developers Questions and Answers

Best practices in Apex development for triggers and service layers include:

Avoiding DML operations and queries in loops.

Handling bulk processing efficiently.

Option A ensures compliance by performing all updates at the end, reducing the risk of hitting governor limits.

An External ID field is used to match data in Salesforce with data from external systems (like an on-premise SQL database). It allows for easy upserts and data integration without relying on Salesforce IDs.

Why not other options?

A: External objects are used for real-time integration with external systems but do not address data matching directly.

C: Formula fields are calculated fields and cannot be used for data matching.

D: Lookup fields are used for creating relationships between objects within Salesforce, not for matching external data.

A validation rule can ensure that the Lead Source field is populated before the Lead is converted. This prevents users from proceeding unless the required data is entered.

Why not other options?

A: Triggers are programmatic, whereas a declarative solution like validation rules is simpler and more efficient.

B: Lead Conversion field mapping maps fields between Lead and Account/Contact but cannot enforce field requirements.

C: A formula field is read-only and cannot enforce user input.

The correct implementation of the CheckPaymentProcessor class must adhere to the PaymentProcessor interface. To accomplish this:

Use the implements keyword to signify that the CheckPaymentProcessor class is implementing the PaymentProcessor interface.

Define the pay method in the CheckPaymentProcessor class, as it is required by the PaymentProcessor interface.

The pay method must match the method signature defined in the PaymentProcessor interface (void pay(Decimal amount)).

Explanation of Option D:

It uses implements PaymentProcessor to correctly indicate that the class adheres to the interface.

The pay method is properly implemented with the required method signature and includes a placeholder for functional code.

Other Options:

Option A: The pay method is not implemented correctly (no method body).

Option B: Incorrect use of extends instead of implements (interfaces are implemented, not extended).

Option C: Same issue as Option B, with a slight variation in formatting.

Developer Sandboxes are ideal for individual developers. They provide the same configuration as production and allow developers to work independently.

Full Sandbox: Used for staging or testing environments, not suitable for individual developer work.

Developer Edition: Not connected to the production org and lacks sandbox functionality.

Partner Developer Edition: Used by ISVs for AppExchange development, not suitable for internal teams.

Why External ID?

The Order Number is used to identify records uniquely, both in Salesforce and in external systems.

Marking it as an External ID ensures it can be matched or referenced during data imports and integrations.

Why Unique?

Setting the field as Unique ensures that duplicate values are not allowed for the Order Number.

Why Not Other Options?

A. Indirect Lookup: Used for external object relationships, which is not applicable here.

B. Direct Lookup: Not relevant for unique field identification.

D. Lookup: Used for creating relationships, not for identifying unique fields.

C. Update the PrimaryId__c field definition to mark it as an External Id:

Marking PrimaryId__c as an External Id allows Salesforce to use this field to match records during the data import process, streamlining the process of mapping CSV rows to existing Candidate__c records.

External Id fields are indexed and can be used in tools like Data Loader, Data Import Wizard, or API-based upserts to ensure that records are matched correctly based on the value of the external ID field.

In this case, since PrimaryId__c is unique, marking it as an external ID eliminates the need for custom triggers or flows.

Why this is the best solution?

This technique leverages built-in Salesforce capabilities (no need for custom code or automation).

It ensures accurate record matching and is the standard approach for data enrichment tasks involving unique identifiers.

Why not the other options?

A. Upload the CSV into a custom object related to Candidate__c:

This approach unnecessarily introduces another object, adding complexity. The goal is to update existing Candidate__c records, not store the data in a separate object.

B. Create a before insert trigger to correctly map the records:

Using triggers for this purpose is overengineering. Salesforce already provides tools like upsert for this exact use case. Writing a trigger would require additional effort and could introduce unintended errors or performance issues.

D. Create a before save flow to correctly map the records:

While flows are powerful, they are not the optimal solution for this use case. Data mapping is better handled using an external ID during import to ensure proper matching and updates.

To embed a Lightning component in a Visualforce page, the following are required:

A: is necessary to include the Lightning framework on the Visualforce page.

C: $Lightning.use() initializes the Lightning app and is essential for using Lightning components.

Why not other options?

B: $Lightning.createComponent is used for creating a specific Lightning component but is not enough on its own.

D: includes SLDS (Styling) but is unrelated to embedding Lightning components.

E: This is not a valid syntax.

Flow Builder:

Flow Builder can evaluate record criteria using a Decision element and then send an outbound message using the "Action" element.

Allows automation without Apex.

Approval Process:

Approval Processes can evaluate criteria and trigger outbound messages as one of the associated actions.

Why Not Other Options?

C. Entitlement Process: Focuses on managing entitlements, not triggering outbound messages.

D. Next Best Action: Used for recommendations and guided actions, not for triggering outbound messages.

When an Account record is created, the following happens:

Before insert trigger increments the count field once.

After insert record-triggered flow executes and increments the count again.

When the record is subsequently updated:

Before update trigger increments the count again.

After update record-triggered flow increments it once more.

Thus, the final value of the count field = 4.
