SALESFORCE-PD1 Practice Test 22 — 15 Questions

Question 1

A developer wrote a batch job that encounters unhandled exceptions on specific records. To ensure that processing of other records continues despite errors in a chunk, what parameter should be configured in the start method or execution?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Database.upsert with allOrNone set to false. Using Database.executeBatch with the default scope or handling exceptions within the execute method using try/catch ensures successful records are committed while failed ones can be logged.

Answer

Database.allowsCallouts

Answer

System.abortJob()

Answer

Database.rollback()

Question 2

A developer has a requirement to perform a callout to an external ERP system immediately when an Opportunity reaches Closed Won. The developer decides to use a future method from an after update trigger. What is a primary architectural limitation of this approach?

Accepted Answer

Future methods cannot accept sObject instances as parameters, requiring ID serialization/deserialization and additional SOQL queries.. Future methods cannot accept sObjects as arguments, requiring the trigger to pass primitive IDs, and they cannot guarantee exact execution order when multiple asynchronous requests fire.

Answer

Future methods cannot make callouts to external systems.

Answer

Future methods execute synchronously in the same database transaction.

Answer

Future methods are limited to 1 callout per transaction.

Question 3

A developer writes an Apex trigger that performs a DML operation on Account records. The Account has a Roll-Up Summary field calculated from child Contact records. What happens during the order of execution regarding roll-up summary field calculations?

Accepted Answer

Roll-up summary fields on the parent record are calculated after child DML and can trigger parent-level rules and triggers.. Roll-up summary fields are recalculated by Salesforce after DML operations on child records and before the transaction completes, triggering parent rules.

Answer

Roll-up summary fields are calculated before before-triggers fire.

Answer

Roll-up summaries are deferred until a nightly batch runs.

Answer

Roll-up summary calculations never trigger parent triggers.

Question 4

A developer needs to ensure that a specific Apex method runs asynchronously because it makes a callout to an external REST API from a standard user interface controller. Which annotation must be added to the method?

Accepted Answer

@future(callout=true). The @future(callout=true) annotation allows an Apex method to run asynchronously and enables it to perform HTTP callouts.

Answer

@ReadOnly

Answer

@InvocableMethod

Answer

@AuraEnabled(callout=true)

Question 5

Which trigger context variable should be used to check if a trigger is running in a before-insert context?

Accepted Answer

Trigger.isBefore && Trigger.isInsert. Trigger.isBefore and Trigger.isInsert are standard context variables.

Answer

Trigger.isBeforeInsert

Answer

Trigger.context == 'beforeInsert'

Answer

Trigger.beforeInsert

Question 6

What is the primary benefit of using a Flow over an Apex trigger for simple field updates?

Accepted Answer

Declarative configuration. Flows are declarative, easier to maintain, and require no code, making them faster to deploy.

Answer

Higher governor limits

Answer

Access to private methods

Answer

Better performance

Question 7

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 8

Which THREE items are included in a debug log?

Accepted Answer

System.debug statements.. Debug logs contain execution details for DML, SOQL, and custom user debug messages.

Answer

Browser cookies.

Answer

User password history.

Question 9

What is the primary benefit of using Flow Builder over Apex triggers when implementing simple field validations?

Accepted Answer

Flows can be managed and updated declaratively without code deployment.. Flow Builder allows administrators and developers to build validations declaratively without writing and maintaining code.

Answer

Flows bypass all system validation rules automatically.

Answer

Flows do not count against governor limits.

Answer

Flows execute faster than compiled Apex triggers.

Question 10

Which THREE actions can cause a governor limit exception during a poorly optimized trigger execution? (Choose three.)

Accepted Answer

Exceeding the maximum synchronous heap size of 6 MB by loading massive attachments into collections.. Queries in loops, too many DML statements, and excessive heap size allocation trigger governor limit exceptions.

Answer

Invoking a future method directly from a scheduled Apex class execute method.

Answer

Accessing Trigger.old in an insert trigger.

Question 11

A developer needs to execute lightweight asynchronous logic that is chainable and allows passing complex objects to the background job. Which asynchronous feature should the developer implement?

Accepted Answer

Queueable Apex. Queueable Apex supports complex member variables including sObjects and custom Apex types, and it can be chained. Future methods only support primitive types and collections of primitive types.

Answer

Schedulable Apex

Answer

Future methods

Answer

Batch Apex

Question 12

A developer needs to execute logic after a record is inserted into the database but before the database commits the transaction. Which trigger event is most appropriate?

Accepted Answer

after insert. The after insert trigger event executes after the record is saved to the database but before the final commit.

Answer

before insert

Answer

before update

Answer

after update

Question 13

A developer needs to access the old values of a record in an Apex trigger. Which collection provides this?

Accepted Answer

Trigger.old. Trigger.old contains the list of records before the update or deletion.

Answer

Trigger.oldMap

Answer

Trigger.map

Answer

Trigger.newMap

Answer

Trigger.new

Question 14

Which of the following describes the behavior of a static variable in Apex?

Accepted Answer

It persists for the duration of the transaction. Static variables are scoped to the transaction and persist across the entire trigger execution.

Answer

It is stored in the database

Answer

It is reset for each trigger event

Answer

It is shared across all users

Question 15

Which THREE of the following are valid uses for the Database.executeBatch method parameters?

Accepted Answer

Passing parameters to the constructor for configuration. The method allows setting the batch size, which is critical for performance tuning.

Answer

Enabling the debug log

Answer

Setting the execution priority
