NEW QUESTION # 51
Assuming that name is a String obtained by an < apex:inputText > tag on a Visualforce page, which two SOQL queries performed are safe from SOQL injection?

A. String query = ' % ' + name + ' % ' ;List < Account > results = [SELECT Id FROM Account WHERE Name LIKE :query];
B. String query = ' SELECT Id FROM Account WHERE Name LIKE ' % ' +String.escapeSingleQuotes (name) + ' % ' ' ;List < Account > results = Database.query(query);
C. String query = ' SELECT Id FROM Account WHERE Name LIKE ' % ' + name.noQuotes()+ ' % ' ' ; List < Account > results = Database.query(query);
D. String query = ' SELECT Id FROM Account WHERE Name LIKE ' % ' + name + ' % ' ' ;List < Account > results = Database.query(query);

Answer: A,B

Explanation:
Answers B, C are correct. Visualforce uses pages, standard controllers, custom controllers, and controller extensions to build server-rendered Salesforce UI. Standard controllers provide built-in record operations such as save, while extensions add custom validation, navigation, and business logic. Large result sets require pagination patterns such as StandardSetController to control view state and page load behavior. The other options either use the wrong platform feature, apply at the wrong layer, or ignore a key Salesforce constraint.
For Platform Developer I, the important point is not just syntax; it is choosing the feature that aligns with transaction behavior, security enforcement, maintainability, and supported metadata capabilities. Reference focus: Lightning Web Components Developer Guide, Lightning Component Reference, Aura Components Developer Guide, and Visualforce Developer Guide. This distinction is important in production orgs because small design mistakes can create deployment failures, runtime exceptions, data-quality defects, or user-visible security gaps once automation is executed in bulk or from multiple entry points.

NEW QUESTION # 52
Given the following Apex statement:
Account myAccount = [SELECT Id, Name FROM Account);
What occurs when more than one Account is returned by the SOQL query?

A. The query fails and an error is written to the debug log.
B. The first Account returned is assigned to myAccount.
C. The variable, myaccount, is automatically cast to the List data type.
D. An unhandled exception is thrown and the code terminates.

Answer: D

Explanation:
* The SOQL query assigns its result directly to a single sObject variable (Account myAccount). If the query returns more than one record, Salesforce throws a QueryException because the system cannot automatically cast multiple results to a single sObject.
* Not Suitable:
* Option A: The variable cannot be automatically cast to a list.
* Option C: The query itself does not fail but throws an exception.
* Option D: The first record is not automatically assigned.

NEW QUESTION # 53

What is the correct definition of a Lightning Web component property that uses the getAccounts method?
