SALESFORCE-PD1 Practice Test 9 — 10 Questions

Question 1

A developer is writing a unit test and needs to assert that a specific custom exception was thrown during invalid input processing. Which pattern should the developer use?

Accepted Answer

Wrap the target code in a try block, add Assert.fail('Expected exception') after the target code, and catch the exception.. Using try-catch blocks with System.assert or Assert.fail inside the try block ensures that if the exception is not thrown, the test fails.

Answer

Use Test.expectException() before calling the method.

Answer

Check Limits.getScriptStatements() after the method call.

Answer

Use System.assert(false, e.getMessage()) inside the catch block.

Question 2

Which THREE statements are true regarding asynchronous Apex governor limits and execution behavior? (Choose three.)

Accepted Answer

Asynchronous Apex jobs execute in their own separate transaction with independent governor limits.. Asynchronous jobs have higher limits (heap, CPU time), run in separate transactions, and can be monitored via AsyncApexJob.

Answer

Future methods can be chained indefinitely without any depth limitations.

Answer

Batch Apex jobs cannot make external web service callouts.

Question 3

Which TWO of the following are valid ways to execute Apex unit tests in Salesforce?

Accepted Answer

Developer Console. Tests can be run via the Developer Console or the Apex Test Execution page in Setup.

Answer

Object Manager settings

Answer

User Management settings

Answer

Change Sets menu

Question 4

Which feature allows administrators to invoke an Apex method from a Flow?

Accepted Answer

@InvocableMethod. The @InvocableMethod annotation exposes Apex methods to flows and process builder.

Answer

@RemoteAction

Answer

@future

Answer

@AuraEnabled

Question 5

A developer creates an Apex trigger that updates related Contact records whenever an Account record is updated. The trigger performs a DML operation on the Contacts. During testing, updating an Account causes the trigger to fire infinitely and throw a System.LimitException: Maximum trigger depth exceeded. Which design pattern should the developer implement to prevent this recursion?

Accepted Answer

Use a static boolean flag in a helper class to ensure the trigger block executes only once per transaction.. Using a static boolean flag in a helper class is the standard Salesforce pattern to prevent recursive trigger execution by tracking whether the trigger logic has already run in the current transaction.

Answer

Use a Database.setSavepoint() before the DML operation to rollback if recursion occurs.

Answer

Convert the trigger logic into a Queueable Apex job to defer execution to a separate transaction.

Answer

Check Trigger.isExecuting to determine if the trigger is running in a recursive context.

Question 6

Which TWO features are characteristic of Flow Builder compared to Apex triggers? (Choose two.)

Accepted Answer

Flows provide a visual canvas for building automation logic without writing code.. Flow Builder is declarative, provides visual debugging, and allows point-and-click creation.

Answer

Flows execute entirely on client-side browsers.

Answer

Flows require compilation into bytecode and deployment via metadata APIs or developer toolchains.

Answer

Flows cannot interact with custom objects or custom fields.

Question 7

During the Salesforce save order of execution, when are before triggers executed relative to custom validation rules?

Accepted Answer

Before triggers execute before custom validation rules.. Before triggers execute before custom validation rules are evaluated, allowing developers to modify field values before validation checks run.

Answer

Before triggers execute after custom validation rules.

Answer

Before triggers execute after the record is committed to the database.

Answer

Before triggers execute concurrently with custom validation rules.

Question 8

A developer is analyzing a debug log and notices that it is truncated because it exceeded the maximum file size limit. Which action should the developer take to capture only the relevant Apex code execution details without exceeding the limit?

Accepted Answer

Adjust the Trace Flag log levels to reduce verbosity for unnecessary categories like Database and Workflow.. Refining log categories and levels ensures only necessary debug statements are recorded, preventing truncation.

Answer

Increase the maximum log file size in company profile settings.

Answer

Disable all validation rules in the org temporarily.

Answer

Switch the debug log perspective to 'Development Harvester'.

Question 9

Which governor limit applies specifically to the total number of asynchronous Apex executions (such as future methods and queueable jobs) enqueued in a 24-hour period for an Enterprise Edition org?

Accepted Answer

10,000 or 2.5 times the number of user licenses, whichever is greater. The asynchronous Apex execution limit restricts the total number of future calls, queueable jobs, and scheduled jobs that can be enqueued per 24 hours.

Answer

100 SOQL queries per transaction

Answer

6MB heap size limit

Answer

50 DML statements per transaction

Question 10

A developer has an Apex trigger that fires on Account update. Inside the trigger, it calls a future method to update related Contact records. During testing with 150 Account records modified simultaneously, the developer receives a System.LimitException: Too many future calls. What is the cause of this exception?

Accepted Answer

The trigger exceeded the maximum limit of 50 future method calls per Apex transaction.. Future methods cannot be called from within other asynchronous contexts or inside triggers when the trigger processes more records than the future call limit allows per transaction (e.g. max 50 future calls per transaction).

Answer

The total daily asynchronous limit was reached.

Answer

Future methods cannot be invoked from inside an Apex trigger context.

Answer

The future method tried to execute a SOQL query exceeding the limit.
