Salesforce PDII - Salesforce Certified Platform Developer II (Plat-Dev-301)

Apex managed sharing provides a programmatic way to share records when the organization-wide default for an object is Private. The Quality_Controller__c field can be used within a trigger or class to share records with the specified user using Apex managed sharing.

The error "You have uncommitted work pending. Please commit or rollback before calling out" usually indicates that DML operations (like insert, update, delete) are being performed before a callout in a test context. This is not allowed because Salesforce does not support this sequence of operations in a single transaction. However, the use of seeAllData=true is generally not a recommended practice and does not address the core issue of mixed DML and callouts in tests. The correct solution is to use a mocking framework to simulate the callout response. By using Test.setMock(), developers can avoid performing actual callouts in test methods, thus bypassing the uncommitted work error.

Making a callout from an Apex trigger is not allowed synchronously; hence, such callouts must be performed in an asynchronous context. The only way to perform this within the Salesforce platform is by using asynchronous Apex, such as @future methods or Queueable Apex.

Salesforce validation rules are declarative and can be used to validate more than one field on an object and display multiple error messages. This approach requires minimal JavaScript code and uses Salesforce's built-in validation framework. References:

Validation Rules

Salesforce CLI with Salesforce DX is the best tool for managing a source-driven deployment process. It facilitates version control, scriptable deployment, and rollback, and is optimized for collaboration and continuous integration.

The System.CalloutException with the message "Unauthorized endpoint" typically indicates that the endpoint to which the callout is being made has not been authorized in the Salesforce org's security settings. To resolve this, the developer must navigate to the Remote Site Settings in the Salesforce Setup and add the endpoint URL as a new remote site. This step is necessary to authorize the Salesforce org to send outbound callouts to that specific endpoint. Annotating with @Future(Callout=true) is necessary for making callouts from methods that perform DML operations, but it does not resolve endpoint authorization issues. Similarly, changing the access modifier or using SetHeader() for authentication would not address the unauthorized endpoint error.

Creating a custom Apex class with methods to determine the appropriate approver is the most suitable approach when dealing with complex logic and the need for flexibility. This approach allows for centralized logic that can be easily maintained and updated as business requirements change.

In this scenario, the governor limit for DML statements (150 DML operations and 10,000 DML rows per transaction) will be exceeded because the updates will cascade across related objects, significantly multiplying the number of records processed.

To optimize the code's efficiency when assigning users to the Account's Auditor field based on the audit code, the following changes should be considered:

B. Building a map of audit code to accounts (Map<string, List<Account>>) would allow for efficient grouping of accounts by their audit code. This would make it easier to process accounts with the same audit code in a single operation, reducing the number of SOQL queries and DML operations needed.

D. Adding a WHERE clause to the SOQL query to filter on audit codes would limit the number of records returned by the query. This means the code only processes relevant User records with matching audit codes, thereby reducing the processing time and memory consumption.

Option A is not recommended because querying for all distinct audit codes without any context of the accounts being processed could be inefficient. Option C is less effective because it would involve creating a mapping of Account Ids to audit codes, which doesn't aid in the efficient assignment of auditor to accounts.

When faced with performance issues in a Lightning Web Component (LWC) due to SOQL query load times, the optimal approach is often to improve the query's selectivity. This can be achieved by using a selective SOQL query with a custom index. Salesforce can create custom indexes to improve the performance of queries that cannot be optimized through standard indexing. When a query is selective, it can efficiently retrieve records from the database using the index, thus reducing the query execution time and speeding up the component's performance when filters are changed. The other options (returning all records, using SOSL, or client-side caching) do not directly address the root cause of the performance issue, which is the need for a more efficient database operation.
