NEW QUESTION # 127
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?

A. Use lazy loading and a transient List variable.
B. Implement pagination with a StandardSetController.
C. Use JavaScript remoting with SOQL Offset.
D. Implement pagination with an OffsetController.

Answer: B

Explanation:
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.

NEW QUESTION # 128
What should a developer use to obtain the Id and Name of all the Leads, Accounts, and Contacts that have the company name "Universal Containers?

A. FIND 'Universal Conteiners' IN CompenyName Fields RETURNING leadjid, name), sccount(ad, name}, conteact(id, name)
B. PIND 'Universal Centainers' IN Name Fields RETURNING lead(id, name), saceount(id, mame), contact (id, name)
C. SELECT lead(id, name), account (id, name}, contact(id, name) FROM Lead, Account, Contact WHERE Name = "Universal Containers'
D. SELECT Lead.id, Lead.Neme, Account,Id, Account.Neme, Contact.id, Contact.Neame FROM Lead, Account, Contact WHERE CompanyName = "Universal Containers*

Answer: A

Explanation:
Option A: This is the correct syntax for SOSL to retrieve data across multiple objects. It searches for
"Universal Containers" in theCompanyNamefields and returns the specified fields forLead,Account, andContact.
Other Options:
Option BandD: These are invalid SOQL statements since SOQL does not support multi-object queries.
Option C:Namefields are not relevant to the search term "CompanyName."
SOSL Syntax
