PDI Exam Dumps - Salesforce Developers Questions and Answers

Execution Flow:

Thedo-whileloop executes the body of the loop before evaluating the condition.

Initialx = 0.

Inside the loop:x = 1(reassignment) and then incremented to2.

The conditionx < 1is false after the first iteration, so the loop exits.

Debug Output:System.debug(x)logs2.

Scratch orgs are temporary, source-driven Salesforce environments used for development and testing. They allow developers to:

Work on independent features without interfering with each other's configurations.

Utilize a source-driven development model for CI/CD pipelines.

Since theCaseandDefect__cobjects have aPrivateorganization-wide default (OWD), their records must be explicitly shared for a user to gain access to the relatedCase_Defect__crecord. Sharing both parent records ensures that the user can access the junction object and the associated parent objects.

Using aforloop allows iterating through the list, and aniforif-elsecondition inside can evaluate theLastModifiedDatefor each account to determine its status.

Anonymous Apex allows developers to execute ad hoc code snippets without creating a permanent class or trigger. It is useful for tasks like bulk data manipulation or testing.

B. Deleting 15,000 inactive Accounts:

Anonymous Apex can perform ad hoc bulk operations to clean up data after a deployment.

Example:

Use Cases:List inactiveAccounts = [SELECT Id FROM Account WHERE IsActive__c = false LIMIT 15000];

delete inactiveAccounts;

C. Running a batch Apex class:

Anonymous Apex can execute batch jobs for data processing.

Example:

apex

Copy code

Database.executeBatch(new UpdateContactBatch());

A. Schedule an Apex class to run periodically: This requires a scheduled job, not Anonymous Apex.

D. Add unit test code coverage: Unit tests must be written in test classes and cannot be added using Anonymous Apex.

Option B: To update a junction object, the user needsRead/Writeaccess to the primary relationship object.

Option C: The user must also haveRead/Writeaccess on the junction object itself.

To override the Edit button in both Salesforce Classic and Lightning Experience:

Use aVisualforce pagefor Salesforce Classic.

Use aLightning componentfor Lightning Experience by configuring the Lightning override.

Option A contains code that improperly handles user input, which may lead to a security vulnerability such as SOQL injection. To avoid this, always use bind variables when constructing queries.

To create and manage scratch orgs in Salesforce DX, the Dev Hub must be enabled in your Salesforce production or Developer Edition org. Dev Hub acts as the central hub for managing scratch orgs.

TheBoolean isOKvariable is declared but not initialized, meaning its value isnullby default in Apex.

The code evaluates theif-elseconditions in sequence:

Condition 1:isOK == false && theString == 'Hello'

isOKisnull, so this evaluates tofalse.

Condition 2:isOK == true && theString == 'Hello'

Again,isOKisnull, so this evaluates tofalse.

Condition 3:isOK != null && theString == 'Hello'

isOKisnull, soisOK != nullevaluates tofalse.

Else block: None of the above conditions are true, so the code enters theelseblock and setsx = 4.
