SAMPLE QUESTIONS
Question # 1
A company decides to implement a new process where every time an Opportunity iscreated, a follow up Task should be created and assigned to the Opportunity Owner.What is the most efficient way for a developer to implement this?
A. Auto-launched flow on Task B. Apex trigger on Task C. Task actions D. Record-trigger flow on Opportunity
Answer: D Explanation:A record-trigger flow on Opportunity is the most efficient way for a developer to implementthis requirement, because it allows the developer to automate the creation and assignmentof a Task without writing any code. A record-trigger flow can be configured to run when arecord is created, updated, or deleted, and it can access and update related records usingflow elements1. A record-trigger flow on Opportunity can also use the $Record globalvariable to access the Opportunity Owner and assign the Task to them2.An auto-launched flow on Task is not an efficient way to implement this requirement,because it requires the developer to manually invoke the flow from another process, suchas a trigger or a button3. An auto-launched flow on Task cannot access the Opportunityrecord or its Owner without a lookup element, which adds complexity and reducesperformance.An Apex trigger on Task is not an efficient way to implement this requirement, because itrequires the developer to write and maintain code, which is more prone to errors andharder to debug than a flow. An Apex trigger on Task also cannot access the Opportunityrecord or its Owner without a SOQL query, which consumes governor limits and increasesthe risk of hitting the 101 SOQL limit.A Task action is not an efficient way to implement this requirement, because it requires the user to manually create and assign the Task from the Opportunity record page. A Taskaction does not automate the process, and it relies on the user to remember and follow thebusiness rule.

Question # 2
A developer creates a custom exception as shown below:public class ParityException extends Exception {}What are two ways the developer can fire the exception in Apex?Choose 2 answers
A. new ParityException();: B. throw new ParityException("parity does not match"); C. new ParityException('parity does not match'); D. throw new ParityException();
Answer: B,D Explanation: To use a custom exception, you can create an instance of the custom exception class anduse the throw keyword to throw the exception. You can also optionally provide a customerror message or a chained exception cause as arguments to the custom exceptionconstructor. The syntax for throwing a custom exception is:throw new CustomException(optional_message, optional_cause);Therefore, the options B and D are valid ways to fire the custom exception in Apex. Theoptions A and C are invalid because they only create an instance of the custom exceptionclass, but do not throw it. Also, the option C uses single quotes instead of double quotes forthe error message, which is not allowed in Apex. References: You can find moreinformation about custom exceptions in the Apex Developer Guide and the Apex ReferenceGuide on Salesforce’s official website. You can also read this blog post for a tutorial oncreating and using custom exceptions.
Question # 3
Universal Containers has a Visualforce page that displays a table of every Container__cbeing rented by a given Account. Recently thispage is failing with a view state limit because some of the customers rent over 10,000containers.What should a developer change about the Visualforce page to help with the page loaderrors?
A. Use JavaScript remotlng with SOQL Offset. B. Implement pagination with a StandardSetController. C. Implement pagination with an OffaetController. D. Use lazy loading and a transient List variable.
Answer: B Explanation:The view state limit is the maximum size of the serialized version of the page state that canbe transferred between the server and the client. The view state includes the components,field values, and controller state of the page. To reduce the view state size, a developercan use a StandardSetController, which allows the developer to create pagination for a setof records without having to manually manage the query and the results. AStandardSetController can handle up to 10,000 records, and only the records that aredisplayed on the current page are included in the view state. This way, the developer canavoid querying and storing all the records in a list variable, which would increase the viewstate size and potentially cause errors.

Question # 4
As part of new feature development, a developer is asked to build a responsive applicationcapable of responding to touch events, that will be executed on stateful clients.Which two technologies are built on a framework that fully supports the businessrequirement? Choose 2 answers
A. Aura Components B. Vlsualforce Components C. Lightning Web Components D. Visualforce Pages
Answer: A,C Explanation:Aura Components and Lightning Web Components are two technologies that are built on aframework that fully supports the business requirement of building a responsive applicationcapable of responding to touch events, that will be executed on stateful clients. Bothtechnologies are part of the Lightning Component Framework, which is a modern UIframework for developing dynamic web apps for mobile and desktop devices. TheLightning Component Framework uses standard web technologies, such as HTML, CSS,JavaScript, and Web Components, to create reusable and interoperable components thatcan adapt to different screen sizes, devices, and orientations. The framework also providesfeatures such as data binding, event handling, state management, and server-sideintegration, to enable developers to create rich and interactive user interfaces.Aura Components are the original technology for creating Lightning components. They usea custom XML-based markup language, Aura, to define the component structure andbehavior. Aura Components can respond to touch events using the ui:input component,which provides a generic input element that can handle different input types, such as text,number, date, checkbox, radio, toggle, and email. The ui:input component also supportstouch gestures, such as swipe, tap, and pinch, by using the ontouchstart, ontouchend,ontouchmove, and ontouchcancel attributes. Aura Components are stateful, meaning thatthey maintain their state on the client-side and communicate with the server only whennecessary. This reduces the network traffic and improves the performance and userexperience.Lightning Web Components are the newer technology for creating Lightning components.They use standard HTML, CSS, and JavaScript to define the component structure andbehavior. Lightning Web Components can respond to touch events using the standardHTML input element, which provides a native input element that can handle different inputtypes, such as text, number, date, checkbox, radio, toggle, and email. The input elementalso supports touch gestures, such as swipe, tap, and pinch, by using the standard touchevent listeners, such as touchstart, touchend, touchmove, and touchcancel. Lightning WebComponents are also stateful, meaning that they maintain their state on the client-side andcommunicate with the server only when necessary. This reduces the network traffic and improves the performance and user experience.Visualforce Components and Visualforce Pages are two technologies that are not built on aframework that fully supports the business requirement of building a responsive applicationcapable of responding to touch events, that will be executed on stateful clients. VisualforceComponents are reusable UI elements that can be used in Visualforce Pages. VisualforcePages are web pages that can display and interact with Salesforce data and logic.Visualforce Components and Pages use a custom XML-based markup language,Visualforce, to define the UI elements and behavior. Visualforce Components and Pagescan be made responsive by using the Salesforce Lightning Design System (SLDS), whichis a collection of design guidelines, components, and resources that enable developers tocreate consistent and beautiful user interfaces across devices. However, VisualforceComponents and Pages do not have native support for touch events, and require customJavaScript code to handle them. Visualforce Components and Pages are also stateless,meaning that they do not maintain their state on the client-side and communicate with theserver on every request. This increases the network traffic and affects the performance anduser experience.References:Lightning Component FrameworkAura Components Developer GuideLightning Web Components Developer GuideVisualforce Developer GuideSalesforce Lightning Design System
Question # 5
Universal Hiring uses Salesforce to capture job applications. A salesforce administratorcreated two custom objects; Job__c acting as the maste object, Job _Application__c actingas the detail.Within the Job ___c object, a custom multi-select picklist, preferred Locations __c, containsa list of approved states for the position. EachJob_Application__c record relates to a Contact within the system through a master-detailrelationship.Recruiters have requested the ability to view whether the Contact's Mailing State valuematches a value selected on the Preferred_Locations__c field,within the Job_Application__c record. Recruiters would like this value to be kept in sync ifchanges occur to the Contact's Mailing State.What is the recommended tool a developer should use to meet the business requirement
A. Roll-up summary field B. Apex trigger C. Formula field D. Record-triggered flow
Answer: D Explanation:A record-triggered flow is a type of flow that runs when a record is created or updated1. Itcan perform actions such as updating fields, creating records, sending emails, and callingApex classes2. A record-triggered flow is the recommended tool for this scenario becauseit can compare the Contact’s Mailing State with the Job’s Preferred Locations, and updatea custom field on the Job Application object accordingly. It can also handle changes to theContact’s Mailing State and keep the Job Application field in sync3.

Question # 6
What can be easily developed using the Lightning Component framework?
A. Customized JavaScript buttons B. Salesforce Classic user Interface pages C. Lightning Pages D. Salesforce integrations
Answer: C
Question # 7
Which two characteristics are true for Lightning Web Component custom events?Choose 2 answers
A. Data may be passed In the payload of a custom event using a wire decoratedproperties. B. By default a custom event only propagates to its immediate container and to itsimmediate child component. C. By default a custom event only propagates to it's immediate container. D. Data may be passed in the payload of a custom event using a property called detail.
Answer: C,D Explanation: The correct answer is C and D because they are the characteristics ofLightning Web Component custom events as described in the Salesforce documentation1.A custom event is an event that a component fires to communicate data to othercomponents. By default, a custom event only propagates to its immediate container, whichis the component that created it or the component that hosts the component that created it.To propagate the event beyond the immediate container, the component that fires theevent must set the composed property of the event to true. A custom event can pass datato other components in the payload using a property called detail, which can be anyJavaScript object. The other options are incorrect because they are not true for LightningWeb Component custom events. Option A is incorrect because a wire decorated propertyis a property that is automatically updated with data from a Salesforce org or an Apexmethod. It is not related to custom events. Option B is incorrect because a custom eventdoes not propagate to its immediate child component by default, unless the child component is the one that fires the event or the event is composed.

Question # 8
A developer is designing a new application on the Salesforce platform and wants to ensureit can support multiple tenants effectively.Which design framework should the developer consider to ensure scalability andmaintainability?
A. Flux (view, action, dispatcher, and store) B. Waterfall Model C. Agile Development D. Model-View-Controller (MVC)
Answer: D Explanation:The correct answer is D because the Model-View-Controller (MVC) design framework is abest practice for developing scalable and maintainable applications on the Salesforceplatform. The MVC framework separates the application logic into three layers: the model,which represents the data and business logic; the view, which displays the user interfaceand user interactions; and the controller, which mediates the communication between themodel and the view. By using the MVC framework, developers can modularize their code,reuse components, and avoid tight coupling between layers. The other options areincorrect because they are not design frameworks, but rather development methodologiesor architectures. Flux is an architecture for building user interfaces with React, a JavaScriptlibrary. Waterfall and Agile are methodologies for managing software development projects,with different approaches to planning, testing, and delivering software.

Question # 9
Universal Containers wants to automatically assign new cases to the appropriate supportrepresentative based on the case origin. They have created a custom field on the Caseobject to store the support representative name.What is the best solution to assign the case to the appropriate support representative?
A. Use a trigger an the Case object. B. Use a formula field on the case object. C. Use a validation rule on the Case object. D. Use an Assignment Flow element.
Answer: D Explanation: An Assignment Flow element is a logic element that allows you to set valuesin variables, collection variables, record variables, record collection variables, and globalvariables1. You can use an Assignment Flow element to assign the support representativename to the custom field on the Case object based on the case origin. This way, you canautomate the case assignment process without writing any code or using any formula. Atrigger, a formula field, and a validation rule are not the best solutions for this scenario, asthey either require code, are not dynamic, or do not change the field value.

Question # 10
What are two considerations for deploying from a sandbox to production?Choose 2 answers
A. Should deploy during business hours to ensure feedback can be Quickly addressed B. All triggers must have at least one line of test coverage. C. At least 75% of Aptx code must be covered by unit tests. D. Unit tests must have calls to the System.assert method.
Answer: C,D Explanation: The correct answers are C and D because they are the minimumrequirements for deploying Apex code from a sandbox to production. According to theSalesforce documentation1, “To deploy Apex or package it for the AppExchange, at least75% of your Apex code must be covered by unit tests, and all of those tests must completesuccessfully.” Additionally, “Every test method must use the System.assert methods toverify that the expected behavior occurs.” The other options are incorrect because they arenot mandatory for deployment, but rather best practices or recommendations. Deployingduring business hours may not be feasible or desirable for some organizations, dependingon their availability and change management processes. Having at least one line of test coverage for each trigger is not enough to ensure code quality and functionality, and maynot meet the 75% code coverage requirement.
