NEW QUESTION # 52
Which two are phases in the Aura application event propagation framework? Choose 2 answers
- A. Bubble
- B. Default
- C. Control
- D. Emit
Answer: A,B
Explanation:
The Aura application event propagation framework supports three phases for the propagation of application events: capture, bubble, and default. The capture and bubble phases are similar to DOM handling patterns and provide an opportunity for interested components to interact with an event and potentially control the behavior for subsequent handlers. The default phase preserves the framework's original handling behavior and can be useful for handling application events that affect components in different sub-trees of your app. The emit and control phases are not part of the Aura application event propagation framework.

NEW QUESTION # 53
A developer is migrating a Visualforce page into a Lightning web component.
The Visualforce page shows information about a single record. The developer decides to use Lightning Data Service to access record data.
Which security consideration should the developer be aware of?
- A. The with sharing keyword must be used to enforce sharing rules.
- B. Lightning Data Service handles sharing rules and field-level security.
- C. The isAccessible ( ) method must be used for field-level access checks
- D. Lightning Data Service ignores field-level security.
Answer: B
Explanation:
Lightning Data Service is the preferred (and easiest) way to work with Salesforce data. With Lightning Data Service, developers use JavaScript to connect components to Salesforce data1. Lightning Data Service also provides security by making server calls to secure User Interface API endpoints2. Lightning Data Service respects the sharing rules and field-level security of the current user, so developers do not need to write any additional code to enforce them3. The other options are either incorrect or irrelevant for Lightning Data Service. References:

NEW QUESTION # 55
The sales management team at Universal Container requires that the Lead Source field of the Lead record be populated when a.. converted.
What should be done to ensure that a user populates the Lead Source field prior to converting a Lead?
- A. Use a formula field.
- B. Use a validation rule.
- C. Create an after trigger on Lead.
- D. Use Lead Conversation field mapping.
Answer: B
Explanation:
The Lead Source field is a standard picklist field that indicates the source of the lead, such as web, phone inquiry, partner referral, and others1. The Lead Source field is related to the contact, account, and opportunity Source fields, and the value can be inherited from one field to the next as a lead progresses through the funnel2. To ensure that a user populates the Lead Source field prior to converting a lead, the best option is to use a validation rule. A validation rule is a formula that evaluates the data in one or more fields and returns a value of true or false3. Validation rules verify that the data a user enters in a record meets the standards you specify before the user can save the record3. By creating a validation rule on the Lead object that checks if the Lead Source field is blank, you can prevent the user from converting the lead without filling in the Lead Source field. You can also display a custom error message to inform the user of the requirement3. For example, the validation rule formula could be:
ISBLANK(LeadSource)
And the error message could be:
Please enter a value for Lead Source before converting the lead.
Using a formula field, Lead Conversion field mapping, or an after trigger on Lead are not effective ways to ensure that the user populates the Lead Source field prior to converting a lead. A formula field is a read-only field that derives its value from a formula expression you define. It cannot be edited by the user and cannot enforce data entry. Lead Conversion field mapping is a way to specify how fields in the lead record are transferred to the fields in the contact, account, and opportunity records during lead conversion. It cannot prevent the user from converting the lead without entering the Lead Source field. An after trigger on Lead is a piece of Apex code that executes after a lead record is inserted, updated, deleted, or undeleted. It cannot validate the data entered by the user before the lead conversion occurs.

NEW QUESTION # 56
Universal Hiring uses Salesforce to capture job applications. A salesforce administrator created two custom objects; Job__c acting as the maste object, Job _Application__c acting as the detail.
Within the Job ___c object, a custom multi-select picklist, preferred Locations __c, contains a list of approved states for the position. Each Job_Application__c record relates to a Contact within the system through a master-detail relationship.
Recruiters have requested the ability to view whether the Contact's Mailing State value matches 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 if changes occur to the Contact's Mailing State.
What is the recommended tool a developer should use to meet the business requirement?
- A. Apex trigger
- B. Formula field
- C. Record-triggered flow
- D. Roll-up summary field
Answer: C
Explanation:
A record-triggered flow is a type of flow that runs when a record is created or updated1. It can perform actions such as updating fields, creating records, sending emails, and calling Apex classes2. A record-triggered flow is the recommended tool for this scenario because it can compare the Contact's Mailing State with the Job's Preferred Locations, and update a custom field on the Job Application object accordingly. It can also handle changes to the Contact's Mailing State and keep the Job Application field in sync3. References:
