An ant migration tool deployment with a destructivechanges XML file and an empty package .xml file

QUESTION 29
A custom picklist field, Pool Preference , exists on a custom object. The picklist contains the following options: ‘Vegan’, ‘Kosher’, ‘No Preference’. The developer must ensure a value is populated every time a record is created or updated.
What is the optimal way to ensure a value is selected every time a record is saved?

Set “Use the first value in the list as the default value” to True.

Write an Apex trigger to ensure a value is selected,

Mark the field as Required on the object’s page layout.

Mark the field as Required on the field definition.

Marking the field as required on the field definition ensures that the field is always populated during record creation or update. This enforces the rule at the database level.
Other Options:
Option A: Setting a default value ensures a value is present initially but does not enforce a value during updates.
Option B: Writing a trigger is less efficient and adds unnecessary complexity.
Option C: Marking the field as required on the page layout is UI-specific and does not enforce the rule during API or code-based operations.
Field Level Requirements

QUESTION 30
Which statement generates a list of Leads and Contacts that have a field with the phrase ‘ACME’?

QUESTION 31
Universal Containers has a support process that allows users to request support from its engineering team using a custom object, Engineering Support c.
Users should be able to associate multiple Engineering Support __c records to a single Opportunity record.
Additionally, aggregate information
about the Engineering Support _c records should be shown on the Opportunity record.
Which relationship field should be implemented to support these requirements?

Lookup field from Opportunity to Engineering _support__c

Master-detail field from Engineering Support__c to Opportunity

Master-detail field from Opportunity to Engineering Support__c

Lookup field from Engineering Support __c to Opportunity

A master-detail relationship fromEngineering_Support__ctoOpportunityallows multiple childEngineering_Support__crecords to be associated with a single parentOpportunity. It also enables roll-up summary fields to aggregate data from the child records onto the parentOpportunity.
Reference:Master-Detail Relationships
Incorrect Options:
A & D:Lookup relationships do not support roll-up summary fields.
C:Master-detail cannot go in the opposite direction (Opportunity to Engineering_Support__c) for this use case.

QUESTION 32
A company would like to send an offer letter to a candidate, have the candidate sign it electronically, and then send the letter back.What can a developer do to accomplish this?

Create a visual workflow that will capture the candidate’s signature electronically

Develop a Process Builder that will send the offer letter and allow the candidate to sign it electronically.

Install a managed package that will allow the candidate to sign documents electronically

Create an assignment rule that will assign the offer letter to the candidate

QUESTION 33
Universal Containers needs to create a custom user interface component that allows users to enter information about their accounts. The component should be able to validate the user input before saving the information to the database.
What is the best technology to create this component?

Lightning Web Components

Visualforce

Flow

VUE JavaScript framework

To create a custom user interface component that allows users to enter information about their accounts and validate user input before saving, the best technology is:
Option A: Lightning Web Components
Lightning Web Components (LWC):
LWC is a modern UI framework built on web standards, providing efficient performance and a rich set of base components.
Input Validation:
LWCs support client-side validation using standard HTML5 validation and custom validation logic.
Developers can use JavaScript to validate user input before saving data to the database.
User Experience:
LWCs provide a responsive and interactive user experience, which is essential for data entry components.
Reference:
“Use Lightning Web Components to build enterprise-grade apps that deliver unprecedented levels of performance and productivity.”
– Lightning Web Components Developer Guide
Why Other Options Are Less Suitable:
Option B: Visualforce
Visualforce is an older framework and may not provide the modern user experience and performance of LWC.
Option C: Flow
While Flows can be used for guided user interactions, they are less flexible for complex custom validations and custom UI components.
Option D: VUE JavaScript framework
Vue.js is not natively supported within Salesforce for building UI components. Using external frameworks would require additional integrations and may not be supported.
Conclusion:
Lightning Web Components offer the best technology for creating custom UI components with client-side validation in Salesforce.

QUESTION 34
Universal Containers has a Visualforce page that displays a table of every Container___c being rented by a given Account. Recently this page is failing with a view state limit because some of the customers rent over 10,000 containers.
What should a developer change about the Visualforce page to help with the page load errors?

Implement pagination with an OffsetController.

Use JavaScript remoting with SOQL Offset.

Implement pagination with a StandardSetController.

Use lazy loading and a transient List variable.

To address the view state limit error caused by loading over 10,000 records in a Visualforce page, the developer should implement pagination with a StandardSetController.
StandardSetController: This controller allows developers to easily paginate large sets of records in Visualforce pages.
“A StandardSetController object contains a reference to a list of records with pagination support, similar to the display in a list view.”
– Apex Developer Guide: StandardSetController Class
Benefits:
Efficient Data Handling: It retrieves only a subset of records at a time, reducing the amount of data held in view state.
Built-in Pagination: Provides methods to navigate through pages of records (next, previous, etc.).
View State Limit: Visualforce pages have a view state limit of 170KB. Loading all records at once exceeds this limit.
“To optimize your Visualforce pages, minimize your use of view state. The view state of a Visualforce page is limited to 170KB.”
– Visualforce Developer Guide: View State in Visualforce Pages
Why Not Other Options:
A . Implement pagination with an OffsetController: There’s no standard OffsetController in Visualforce. Implementing custom pagination with offsets is less efficient and can be complex.
B . Use JavaScript remoting with SOQL Offset: While JavaScript remoting can reduce view state size, using SOQL OFFSET is not efficient for large offsets (over 2,000 records).
“When using OFFSET with a large number of records, performance degrades significantly.”
– SOQL and SOSL Reference: OFFSET Clause
D . Use lazy loading and a transient List variable: Lazy loading can help, but it doesn’t solve the issue of handling large datasets efficiently. Transient variables reduce view state but do not manage data retrieval or pagination.
Conclusion: Implementing pagination with a StandardSetController is the recommended solution to handle large datasets efficiently in Visualforce pages and prevent view state limit errors.

QUESTION 35
Universal Containers hires a developer to build a custom search page to help users find the Accounts they want. Users will be able to search on Name, Description, and a custom comments field.
Which consideration should the developer be aware of when deciding between SOQL and SOSL?
Choose 2 answers

SOSL is faster for text searches.

SOQL is able to return more records

SOQL Is faster for text searches.

SOSL is able to return more records.

* SOSL:
* Designed for full-text searches, making it faster for unstructured or broad text searches across multiple objects.
* Ideal for searching multiple fields simultaneously.
* SOQL:
* Optimized for structured queries where you need more control over filtering and relationships.
* Can return up to 50,000 records in a single query, while SOSL returns only 2,000.
* C and D are incorrect because SOSL is faster for text searches, not SOQL.
* SOQL vs. SOSL: https://developer.salesforce.com/docs/atlas.en-us.soql_sosl.meta/soql_sosl

if(thisLead.Company != null &&thisLead.RecordTypeId != BUSINESS_RECORDTYPEID){ thisLead.RecordTypeId = BUSINESS_RECORDTYPEID;
}
}
}
