SALESFORCE-PD1 Practice Test 25 — 15 Questions

Question 1

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.)

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

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 2

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 3

Which trigger context variable should a developer use to access the map of old record versions prior to the update operation?

Accepted Answer

Trigger.oldMap. Trigger.oldMap provides a map of IDs to the old versions of the SObject records for update and delete triggers.

Answer

Trigger.old

Answer

Trigger.newMap

Answer

Trigger.new

Question 4

In the Salesforce Order of Execution, when are validation rules evaluated relative to Apex triggers?

Accepted Answer

After Before triggers fire and before the record is saved to the database. Validation rules are executed after the 'Before' triggers fire and before the record is saved to the database.

Answer

Before any Before triggers fire

Answer

Concurrently with After triggers

Answer

After the record is committed to the database and After triggers complete

Question 5

Which trigger context variable returns a map of IDs to the new versions of the sObject records?

Accepted Answer

Trigger.newMap. Trigger.newMap contains the map of IDs to the new versions of the sObject records, available only in update, undelete, and after insert contexts.

Answer

Trigger.old

Answer

Trigger.new

Answer

Trigger.oldMap

Question 6

Which tool is best suited for migrating metadata between two related Salesforce Orgs using a UI-based approach?

Accepted Answer

Change Sets.. Change Sets are designed for moving metadata between linked Salesforce Orgs.

Answer

Force.com IDE.

Answer

Salesforce CLI.

Answer

Metadata API.

Question 7

Which TWO of the following are valid ways to trigger an Apex test run?

Accepted Answer

Apex Test Execution page in Setup.. Tests can be run from the Developer Console and from the Apex Test Execution page.

Answer

From the User record.

Answer

By editing an Apex class.

Answer

From a Workflow Rule.

Question 8

An Apex trigger needs to update fields on the same record that is currently being inserted in a Before Insert trigger context. How should the developer implement this update?

Accepted Answer

Assign values directly to the fields on the records in Trigger.new.. In a before insert trigger, records are already in memory and have not yet been saved to the database. Developers can modify fields directly on the Trigger.new records without calling an explicit DML operation.

Answer

Use an immediate DML statement update Trigger.new; inside the trigger.

Answer

Instantiate a separate list of the same records and call database.insert().

Answer

Utilize an after insert trigger to perform an update DML operation.

Question 9

A developer is troubleshooting an Apex trigger recursion issue where an update operation triggers itself infinitely. Which THREE strategies can the developer use to safely prevent this recursion? Choose 3 options.

Accepted Answer

Utilize Custom Settings or Custom Metadata to provide a global toggle to turn off triggers dynamically.. Trigger recursion can be prevented using static boolean flags in a helper class, utilizing trigger context maps to check if specific fields actually changed, or leveraging custom metadata/settings to disable triggers dynamically.

Answer

Call Limits.getQueries() at the start of every trigger to abort if limits are near.

Answer

Wrap all DML statements in a try-catch block that catches recursion exceptions.

Question 10

In the order of execution, when do record-triggered flows that are configured to run 'before' the record is saved execute?

Accepted Answer

After the before-save Apex triggers. Record-triggered flows configured to run before the record is saved execute after the before-save triggers.

Answer

After the after-save Apex triggers

Answer

Before the before-save Apex triggers

Answer

After the commit to the database

Question 11

Which type of Apex class is best suited for performing complex calculations on large data sets that must run overnight?

Accepted Answer

Batch Apex. Batch Apex is specifically designed for processing large data sets in chunks over time.

Answer

Future method

Answer

Queueable Apex

Answer

Controller extension

Question 12

A developer needs to update a related record. If using Apex, what is the best practice to avoid hitting governor limits?

Accepted Answer

Collect records in a list and perform a single DML statement. Bulkify the code to perform operations on collections rather than individual records.

Answer

Use a future method for each update

Answer

Use a for loop to update records one by one

Answer

Perform DML inside the loop

Question 13

Which THREE criteria are best suited for choosing an Apex Trigger over a Flow?

Accepted Answer

Requirement for high-performance, low-latency execution. Complex bulk logic, heavy computational requirements, and performance-critical operations are best handled in Apex.

Answer

Simple field updates on the same record

Answer

Sending a simple email alert

Question 14

What is the primary purpose of the Salesforce CLI in a CI/CD pipeline?

Accepted Answer

To automate metadata deployment and package management.. The Salesforce CLI is the fundamental tool for programmatically interacting with Salesforce Orgs in automation.

Answer

To provide a visual interface for Change Sets.

Answer

To run unit tests manually.

Answer

To debug Apex in a GUI.

Question 15

Which TWO of the following are valid ways to specify which tests to run in the Salesforce CLI?

Accepted Answer

sfdx force:apex:test:run -c. The CLI allows running specific classes or classes within a namespace.

Answer

sfdx force:apex:test:run -s

Answer

sfdx force:apex:test:run -f

Answer

sfdx force:apex:test:run -u
