Universal Containers implemented a private sharing model for the Account object. A custom Account search tool was developed with Apex to help sales representatives find accounts that match multiple criteria they specify. Since its release, users of the tool report they can see Accounts they do not own. What should the developer use to enforce sharing permission for the currently logged-in user while using the custom search tool?  Use the schema describe calls to determine if the logged-in users has access to the Account object.  Use the without sharing keyword on the class declaration.  Use the UserInfo Apex class to filter all SOQL queries to returned records owned by the logged-in user.  Use the with sharing keyword on the class declaration. Use the with sharing keyword on the class declaration. The with sharing keyword ensures that the Apex code respects the object-level, field-level, and record-level sharing settings for the user who is running the Apex code. This means that the code will only return records that the user has access to, according to their Sharing Settings. You can find more information about the with sharing keyword in the official Salesforce documentation (https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_keywords_sharing.htm).Q37.

Q39. A developer Is Integrating with a legacy on-premise SQL database.What should the developer use to ensure the data being Integrated is matched to the right records in Salesforce?  Lookup field  External ID field  Formula field  External Object Q40. What is the value of the Trigger.old context variable in a before insert trigger?  A list of newly created sObjects without IDs  null  Undefined  An empty list of sObjects Q41.

Which three options should be used to build out the database layer for the application? Choose 3 answers  Roll-Up Summaries  Triggers  Relationships  Flow  Custom Objects and Fields Q42. A developer needs to include a Visualforce page in the detail section of a page layout for the Account object, but does not see the page as an available option in the Page Layout Editor.

Which technique should be implemented to avoid reaching the governor limit?  Use the System.Limits.getQueries() method to ensure the number of queries is less than 100.  Use the System.Limits.getlimitQueries() method to ensure the number of queries is less than 100.  Refector the code above to perform the SOQL query only if the Set of opportunityIds contains less 100 Ids.  Refactor the code above to perform only one SOQL query, filtering by the Set of opportunityIds. Q47. A developer created a trigger on the Account object and wants to test if the trigger is properly bulkified. The developer team decided that the trigger should be tested with 200 account records with unique names.What two things should be done to create the test data within the unit test with the least amount of code?Choose 2 answers  Use Test.loadData to populate data in your test methods.  Create a static resource containing test data.  Use the @isTest (isParallel=true) annotation in the test class.  Use the @isTest (seeAllData=true) annotation in the test class. To test the trigger with 200 account records with unique names using the least amount of code:Option A: Use Test.loadData to populate data in your test methods.Reference:“Test.loadData lets you populate test records by loading the contents of a CSV file into sObjects for use in test methods.”– Apex Developer Guide: Using Test.loadDataOption B: Create a static resource containing test data.“Create a static resource that contains the .csv file for the records you want to load.”– Apex Developer Guide: Loading Test Data from Static ResourcesWhy Other Options Are Incorrect:Option C: The @isTest(isParallel=true) annotation is used to run tests in parallel but does not help in creating test data.Option D: Using @isTest(seeAllData=true) allows access to existing org data, which is not recommended and does not help create unique test data with minimal code.Q48. Which statement should a developer avoid using inside procedural loops? (Choose 2)  System.debug(‘Amount of CPU time (in ms) used so far: ‘ + Limits.getCpuTime() );  List contacts = [SELECT Id, Salutation, FirstName, LastName, Email FROM Contact WHERE AccountId = :a.Id];  If(o.accountId == a.id)  Update contactList; Q49. Consider the following code snippet for a Visualforce page that is launched using a Custom Button on the Account detail page layout.When the Save button is pressed the developer must perform a complex validation that involves multiple objects and, upon success, redirect the user to another Visualforce page.What can the developer use to meet this business requirement?  Apex  trigger  Controller  extension Q50. A developer is debugging the following code to determinate why Accounts are not being created Account a = new Account(Name = ‘A’); Database.insert(a, false); How should the code be altered to help debug the issue?  Add a System.debug() statement before the insert method  Add a try/catch around the insert method  Set the second insert method parameter to TRUE  Collect the insert method return value a Saveresult variable  Loading … Salesforce DEX-450 exam covers a wide range of topics, including Apex classes and triggers, Visualforce pages and components, Lightning Components, data modeling, and testing.
