D. Embed the keywords FOR UPDATE after SOQL statements.

Using the FOR UPDATE clause in SOQL (Salesforce Object Query Language) statements is a Salesforce-provided method specifically designed to lock records during a transaction, preventing race conditions by ensuring that only one process can update those records at a time. Here's how it helps:

Record Locking: When a SOQL query is executed with the FOR UPDATE clause, Salesforce locks the queried records for the duration of the transaction. This means that if another process tries to update the same records before the first transaction is completed, it will be forced to wait until the first transaction is completed and the lock is released.

Preventing Race Conditions: By locking records, Salesforce ensures that updates are processed in a controlled, sequential manner, effectively preventing race conditions where two or more processes attempt to update the same record simultaneously, potentially causing data inconsistency or overwriting changes....

C: Migrate programmatic logic to processes and flows.

Here's why this recommendation is appropriate:

A. Refactoring or optimizing classes and triggers for maximum CPU performance (Option A) may help improve the overall performance of your org, but it won't necessarily prevent race conditions. Race conditions occur when multiple processes attempt to update the same record simultaneously, which can still happen even with optimized code.

B. Disabling classes or triggers that have the potential to obtain the same record (Option B) may solve the immediate issue, but it's not a sustainable solution. It might lead to functional limitations and is not a best practice for handling concurrent updates.

D. Embedding the "FOR UPDATE" keywords after SOQL statements (Option D) is useful for locking records when performing queries, but it doesn't prevent race conditions when multiple processes or triggers are trying to update the same record.

Option C, migrating programmatic logic to processes and flows, is recommended because Salesforce processes and flows have built-in mechanisms to handle record locking and prevent race conditions. By using declarative tools like Salesforce Process Builder and Flows, you can control the sequence of operations and avoid simultaneous updates to the same record. This approach also simplifies maintenance and reduces the likelihood of race conditions in the future....
