SALESFORCE-PD1 Practice Test 23 — 15 Questions

Question 1

When should a developer choose Flow Builder over an Apex Trigger for business automation?

Accepted Answer

When implementing straightforward record-triggered field updates declaratively.. Flow Builder is declarative and preferred for standard point-and-click record updates and screen interactions when complex custom code is unnecessary.

Answer

When performing complex callouts to external REST APIs.

Answer

When writing custom web service classes for external clients.

Answer

When processing millions of records nightly in batches.

Question 2

An asynchronous method needs to be invoked from a standard trigger to perform callouts to an external web service. Which annotation is required for this asynchronous method?

Accepted Answer

@future(callout=true). Future methods annotated with @future(callout=true) are used to perform asynchronous callouts from triggers.

Answer

@TestSetup

Answer

@InvocableMethod

Answer

@ReadOnly

Question 3

An Apex trigger executes during a bulk insert of 300 records. To adhere to best practices regarding governor limits and bulkification, how should SOQL queries be written?

Accepted Answer

Query once outside the loop using a collection of IDs from Trigger.new. Queries must be written using bulkified collections, querying once outside of loops using bind variables for all records in Trigger.new.

Answer

Query inside a for-loop iterating over Trigger.new

Answer

Query each record individually using Limits.getQueries() checks

Answer

Use an asynchronous future method for every individual record

Question 4

A developer has written a Lightning Web Component and Apex controller, and wants to deploy only these specific metadata components to a production org using Salesforce CLI without relying on change sets. Which command is appropriate?

Accepted Answer

sf project deploy start. sf project deploy start deploys source files from a local project directory to a target org.

Answer

sf apex run

Answer

sf org open

Answer

sf project convert mdapi

Question 5

Why should a developer ensure that test classes have at least 75% coverage for production deployment?

Accepted Answer

It is a requirement set by the Salesforce platform.. Salesforce enforces a minimum of 75% Apex code coverage for all production deployments, except for certain metadata types. This requirement ensures that a substantial portion of the code is tested before it reaches production, reducing the risk of runtime errors.

Answer

It makes the code run faster.

Answer

It prevents bugs entirely.

Answer

It automatically generates the test classes.

Question 6

When should a developer choose Flow Builder over Apex for implementing business automation logic?

Accepted Answer

When standard screen interactions, record modifications, and maintenance by administrators are prioritized.. Flow Builder is recommended for standard record transformations, screen prompts, and declarative logic because it is faster to build and maintain.

Answer

When implementing custom encryption algorithms.

Answer

When complex web service callouts with complex XML namespaces need to be parsed.

Answer

When processing millions of records asynchronously in background batches.

Question 7

A developer needs to pass data from a child Lightning Web Component to a parent Lightning Web Component up the component hierarchy. What is the standard mechanism to achieve this?

Accepted Answer

Dispatch a CustomEvent in the child and handle it in the parent's template using an event listener directive.. Child-to-parent communication in LWC is achieved by dispatching a custom event using CustomEvent and listening to it in the parent template.

Answer

Use the @api decorator in the child component to expose a public method that the parent can call directly.

Answer

Publish a message using the Lightning Message Service from the child and subscribe in the parent.

Answer

Mutate a shared global reactive property imported from a common utility JavaScript module.

Question 8

Which CSS methodology forms the foundation of the styling architecture in Salesforce Lightning Design System (SLDS)?

Accepted Answer

BEM (Block Element Modifier). Salesforce Lightning Design System (SLDS) is built on the BEM (Block Element Modifier) CSS naming methodology, which structures class names as block__element--modifier to create predictable, reusable, and scoped styles. SLDS class names such as slds-button, slds-button__icon, and slds-button_brand directly reflect BEM conventions. This methodology underpins SLDS's modularity and maintainability across components.

Answer

Bootstrap grid standards

Answer

OOCSS exclusively without modifiers

Answer

Tailwind utility prefixes

Question 9

A developer is writing a SOQL query to find accounts where the billing country starts with 'United'. Which operator should be used?

Accepted Answer

LIKE 'United%'. The LIKE operator is used in SOQL for wildcard matching, using '%' as the wildcard character.

Answer

MATCHES

Answer

STARTS_WITH

Answer

INCLUDES

Question 10

When using the Metadata API to deploy components, which XML file must be present to define the components included in the package?

Accepted Answer

package.xml. The package.xml file is the manifest that the Metadata API uses to declare which components are included in a deploy or retrieve operation. It lists metadata types and their members, and it must be present in the deployment package. Without it, the Metadata API has no declaration of what to deploy.

Answer

manifest.xml

Answer

deploy.xml

Answer

components.xml

Question 11

Which SOQL aggregate function should a developer use to count the exact number of rows returned by a query without retrieving the records into memory?

Accepted Answer

COUNT(). The COUNT() function returns the number of rows matching the query criteria efficiently as an integer.

Answer

TOTAL()

Answer

SUM()

Answer

SIZE()

Question 12

Where should a developer look in the Salesforce user interface to inspect detailed system debug logs generated during a specific transaction?

Accepted Answer

Setup > Custom Code > Debug Logs. Debug logs are accessed via Setup by navigating to Custom Code > Debug Logs or via the Developer Console.

Answer

Setup > Monitor > Logs

Answer

Setup > Environments > Logs

Answer

Setup > Process Automation > Debug Logs

Question 13

What is the maximum number of batch Apex jobs that can be queued or active concurrently in the Apex flex queue?

Accepted Answer

100. The Apex flex queue holds up to 100 batch jobs waiting to be processed.

Answer

50

Answer

5

Answer

500

Question 14

A developer needs to ensure that an Apex class respects organization-wide defaults, role hierarchies, and sharing rules when querying custom objects. Which keyword should be added to the class definition?

Accepted Answer

with sharing. The with sharing keyword enforces sharing rules of the current user, while without sharing runs in system mode.

Answer

enforce sharing

Answer

without sharing

Answer

inherited sharing

Question 15

Which approach is recommended to ensure test data is cleaned up?

Accepted Answer

The platform automatically rolls back data created in tests.. Salesforce automatically rolls back all data created during a test method (and during @testSetup) when the test completes, so no manual cleanup is required. This transactional isolation ensures tests do not pollute the org's data and do not need finally blocks or delete statements.

Answer

Use the Test.stopTest() method.

Answer

Delete the records manually in the finally block.

Answer

Use a @testSetup method for cleanup.
