SALESFORCE-PD1 Process Automation And Logic Practice Test 8 — 15 Questions

Question 1

During the execution of a trigger, an unhandled exception occurs in an after update trigger. What happens to the database transaction?

Accepted Answer

The entire transaction is rolled back, and no changes are saved to the database.. An unhandled exception in any trigger causes the entire database transaction to roll back entirely.

Answer

Only the records that caused the exception are rolled back; successful records are committed.

Answer

The transaction pauses until the exception is manually resolved by an admin.

Answer

The records are saved, and an email is sent to the system administrator without rolling back.

Question 2

Which interface enables an Apex class to be invoked from a Flow using the InvocableAction framework?

Accepted Answer

None, it uses the @InvocableMethod annotation.. Methods annotated with @InvocableMethod allow Apex to be called from declarative flows.

Answer

Database.Batchable

Answer

Schedulable

Answer

Queueable

Question 3

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 4

A developer needs to write a unit test for a Queueable Apex class. How should the developer verify that the Queueable job executed successfully?

Accepted Answer

Enclose the execution within Test.startTest() and Test.stopTest(), then query for the resulting record changes.. Queueable jobs executed inside Test.startTest() and Test.stopTest() run synchronously upon reaching stopTest(), allowing assertions to be checked immediately after.

Answer

Use System.assertAsync() to poll the job status table.

Answer

Query the AsyncApexJob table without Test.stopTest().

Answer

Call the queueable execute method directly in a try-catch block.

Question 5

Which governor limit applies to the total CPU time in a single synchronous Apex transaction?

Accepted Answer

10,000 milliseconds. The synchronous CPU time limit is 10,000 milliseconds (10 seconds).

Answer

60,000 milliseconds

Answer

5,000 milliseconds

Answer

120,000 milliseconds

Question 6

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 7

A developer needs to write a Batch Apex class that processes records and ensures atomicity per batch chunk. Which TWO statements are true regarding Database.Batchable execution and error handling? (Choose TWO.)

Accepted Answer

Using Database.DMLOptions or Database.insert(list, false) enables partial processing of records within a chunk without failing the entire batch.. Using Database.insert(records, false) allows partial success within a batch chunk, and state can be maintained across chunks if Database.Stateful is used.

Answer

Batch Apex chunks automatically roll back entirely if a single record fails, regardless of DML settings.

Answer

Batch Apex jobs cannot be monitored programmatically via Apex code.

Answer

The finish method executes before all execute chunks have completed.

Question 8

Which TWO best practices should a developer follow when writing bulkified Apex triggers? (Choose TWO.)

Accepted Answer

Perform DML statements and SOQL queries outside of loops by utilizing collections.. Bulkified triggers must operate on collections (Trigger.new) and avoid SOQL/DML inside loops.

Answer

Hardcode record IDs in trigger logic to route specific test accounts.

Answer

Use synchronous callouts directly inside before insert triggers.

Answer

Place SOQL queries inside loops to ensure every record gets fresh data.

Question 9

A developer is analyzing the Salesforce order of execution for a record update. Which TWO events occur AFTER custom validation rules are evaluated? (Choose TWO.)

Accepted Answer

Execution of Assignment Rules and Escalation Rules.. Options C and E are correct because in the Salesforce order of execution, custom validation rules run after before triggers and system validation, and then the process continues to assignment rules and escalation rules (C) for cases/leads, followed later by after-save logic such as record-triggered after flows and Apex after triggers (E). Option A is incorrect because before triggers execute before custom validation rules, not after. Option B is incorrect because it is the reference point itself—custom validation rules are evaluated, so they do not occur after themselves. Option D is incorrect because initial system validation, including required field checks, occurs before custom validation rules are evaluated.

Answer

Execution of Before Triggers.

Answer

Execution of custom validation rules

Answer

Execution of initial system validation (such as required field checks).

Question 10

A developer is choosing between Future methods and Queueable Apex. Which TWO characteristics are unique to Queueable Apex? (Choose TWO.)

Accepted Answer

Queueable Apex returns an AsyncApexJob ID that can be used to monitor job progress.. Queueable Apex supports complex objects and job chaining, unlike future methods.

Answer

Queueable Apex methods can be called synchronously from inside formula fields.

Answer

Queueable Apex does not support asynchronous job chaining.

Answer

Queueable Apex restricts external HTTP callouts entirely.

Question 11

A developer is designing an asynchronous architecture using Batch Apex. Which THREE considerations must be kept in mind regarding Batch Apex behavior? (Choose THREE.)

Accepted Answer

Up to 5 batch jobs can be in execution concurrently for a single organization.. Batch apex jobs are queued in the Flex queue, can execute up to 5 concurrent jobs, and can maintain state using Stateful.

Answer

The maximum batch size query locator limit is 200 records maximum.

Answer

Batch Apex automatically executes synchronously if triggered from a Visualforce controller.

Question 12

A developer needs to schedule an Apex class to run weekly. Which THREE elements are required to implement Schedulable Apex? (Choose THREE.)

Accepted Answer

The public class must implement the Schedulable interface.. Option C is correct because Schedulable Apex requires the class to implement the Schedulable interface, which is the contract that makes the class eligible for scheduling. Option D is correct because the scheduled job must be registered with System.schedule(), passing a job name and a valid Cron expression that defines the weekly recurrence. Option E is correct because the Schedulable interface mandates an execute method with the signature global or public void execute(SchedulableContext sc), which is the entry point invoked when the scheduled job fires. Option A is incorrect because extending the Controller class is unrelated to scheduling and is used for Visualforce controllers, not Schedulable Apex. Option B is incorrect because implementing Database.Batchable<SObject> is required for Batch Apex, not for Schedulable Apex, although a class can implement both interfaces if needed.

Answer

The class must extend the Controller class.

Answer

The class must implement Database.Batchable<SObject>.

Question 13

When comparing Flow Builder decision points and Apex trigger logic, which THREE statements are valid design considerations? (Choose THREE.)

Accepted Answer

Apex triggers provide superior control for complex exception handling and multi-object transaction orchestration.. Flows are declarative, easier to maintain, and execute within governor limits, whereas Apex handles complex integrations and high-volume data manipulations.

Answer

Apex triggers are executed after all Flow Builder automations have completed.

Answer

Flow Builder cannot invoke Apex actions.

Question 14

A developer is troubleshooting a transaction that exceeds governor limits due to SOQL queries. Which THREE techniques help prevent hitting SOQL query limits in Apex? (Choose THREE.)

Accepted Answer

Using maps and collections to store query results and perform in-memory lookups instead of querying inside loops.. Avoiding queries in loops, using aggregate queries, and caching results in maps/collections help avoid SOQL query limit issues.

Answer

Executing SOQL queries inside a for loop iterating over all child records.

Answer

Calling Database.query() for every single record processed in a trigger.

Question 15

A developer needs to execute logic before a record is inserted into the Database to validate field values and prevent invalid records from saving. Which trigger event should the developer use?

Accepted Answer

before insert. Before insert triggers are used to perform validation, update field values, and prevent records from saving by using the addError() method on the records.

Answer

after update

Answer

after insert

Answer

before update
