B. 30 My Platform

The value displayed by the system.debug statement will be 8 because the code block initializes the variable x to 0 and then increments it by 2 in each iteration of the for loop. The loop will break when x is equal to 8 because of the first if statement. Therefore, the value of x at the end of the code block will be 8.

The Lightning Component framework provides an event-driven architecture, allowing components to communicate with each other without being tightly coupled. This promotes better decoupling between components, making the application more modular and easier to maintain. Additionally, the framework offers out-of-the-box components that are suitable for both desktop and mobile devices, enabling developers to quickly build applications for multiple platforms, thereby promoting faster development.

In a Master-Detail Relationship, the detail record inherits the sharing and security settings of its master record. This means that the detail record will have the same level of access and visibility as the master record. On the other hand, in a Lookup Relationship, there is no automatic inheritance of sharing and security settings. Each record in a Lookup Relationship can have its own independent sharing and security settings.

Governor limits in Salesforce prevent Apex code from exceeding certain resource limits, such as CPU time, heap size, and database queries. These limits ensure that one tenant's code does not negatively impact the performance of other tenants on the same instance. Therefore, the statement "Governor limits prevent Apex from impacting the performance of multiple tenants on the same instance" is true.

Roll-up summary fields of type SUM and COUNT are required to find the average of values on detail records in a Master-Detail relationship. The SUM roll-up summary field calculates the total sum of the values on the detail records, while the COUNT roll-up summary field counts the number of detail records. By dividing the sum by the count, the average value can be obtained.

Workflow rules are triggered by certain conditions or events. In this case, the two conditions that cause workflow rules to fire are when an Apex Batch process changes field values and when records are updated using the bulk API. These actions can potentially trigger the workflow rules and initiate any associated actions or processes defined within them.

The correct answer is 03: A SOQL query is located inside of the for loop. This is because having a SOQL query inside a loop can lead to hitting governor limits and performance issues. It is recommended to bulkify the code by moving the query outside of the loop and using collections to store the queried records.

The Metadata API allows for the deployment of Case Settings and Lead Conversion Settings. These components can be deployed using the Metadata API to make changes and configurations to the case and lead conversion settings in Salesforce. This API provides a way to automate the deployment process and manage these settings across different environments.

The user can expect to see "a, a, a" when accessing the custom page. This is because the "mystring" variable is initially set to "a" in the getter method. The "getStringMethod" method does not change the value of "mystring" if it is null, so it remains "a". The "getMyString" method simply returns the string "getMyString". Therefore, when the page is accessed, the values displayed will be "a, a, a".

The two approaches that optimize test maintenance and support future declarative configuration changes are:
1. Creating a method that loads valid Account records from a static resource and calling this method within test methods. This approach allows for easy modification of the static resource to update the test data without changing the test methods.
2. Creating a method that creates valid records and calling this method within test methods. This approach allows for flexibility in creating test data and easily modifying the method to accommodate future changes in record creation requirements.

Formula fields can reference other formula fields on the same object up to one level deep. This means that a formula field can use the value of another formula field in its calculation. Additionally, fields that are referenced by a formula field cannot be deleted until the formula field is modified or deleted. This ensures that the formula field always has the necessary data to perform its calculation.

The correct answer is "call 'Opportunity.StageName.getDescribe().getLabel().'" because it correctly accesses the describe information for the stageName field of the Opportunity object and retrieves the label for that field.

The correct answer is "controller.js". In the Lightning Component framework, the controller.js file is responsible for handling the client-side logic and event handling for the component. The onclick attribute references a JavaScript function defined in the controller.js file, which is then executed when the lightning:button component is clicked.

A list of Account records returned from a Controller Extension method represents the Model in the MVC architecture on the Force.com platform. The Model in MVC is responsible for managing the data and business logic of the application. In this case, the Controller Extension method retrieves a list of Account records, which can be considered as the data representation of the Model. This list of records can then be used by the View and Controller components to display and manipulate the data.

Apex code executed in Anonymous Blocks runs with the permissions of the logged in user, meaning it has the same access and privileges as the user executing the code. Additionally, successful DML operations are automatically committed, meaning any changes made to the database will be saved permanently.

A developer can limit the number of records returned by a SOQL query by referencing the Set in the WHERE clause of the query. This allows the developer to specify a condition that filters the records based on the values in the Set, effectively limiting the results to only those that match the condition.

A developer can determine the overall code coverage for a sandbox from the Apex classes setup page and the Tests tab of the Developer Console. The Apex classes setup page provides a summary of code coverage for all Apex classes in the sandbox, while the Tests tab of the Developer Console allows the developer to run tests and view the code coverage results.

The first option, [FIND 'Acme*' IN ANY FIELDS RETURNING Account, Opportunity], will return records that match the search criteria in any searchable field on the Account and Opportunity objects. The second option, [FIND 'Acme*' RETURNING Account, Opportunity], will also return records that match the search criteria in any searchable field on the Account and Opportunity objects. Both options allow for a broad search across all searchable text fields on the specified objects.

The developer should use the "Use Schema. PicklistEntry returned by Opportunity.StageName.getDescribe().getPicklistValues()" action to get the available picklist values for the Opportunity StageName field. They should also use the "Use Schema. Record Typelnfo returned by Opportunity.SObjectType.getDescribe().getRecordTypeInfos()" action to get the available record types for the Opportunity object.

The given correct answers are valid assignments because they correctly assign the value of the custom formula field "Level__c" to variables of compatible data types.

- Double myLevel = acct.Level__c; assigns the value as a double data type.
- Decimal myLevel = acct.Level__c; assigns the value as a decimal data type.
- Long myLevel = acct.Level__c; assigns the value as a long data type.

These assignments are valid because the custom formula field is defined as a Formula (Number) with two decimal places, which can be easily assigned to variables of these data types.
