NEW QUESTION # 118
Universal Containers ne=ds to integrate with several external systems. The process Is Initiated when a record Is created in Salesforce, The remote systems do not require Salesforce to wait for a response before continuing.
What is the recommended best solution to accomplish this?
Answer: A
Explanation:
Platform events provide a robust and scalable way to communicate changes and events from Salesforce to external systems, especially when there is no requirement for Salesforce to wait for a response. They are designed to support event-driven architectures and can handle high volumes of events that can be published and consumed by external systems. Outbound messages, on the other hand, are limited by the need for an acknowledgment response from the target system, which can introduce latency.

NEW QUESTION # 120
The Account object has a field, Audit_Code_c, that is used to specify what type of auditing the Account needs and a Lookup to User, zudizar_c, that is the assigned auditor. When an Account is initially created, the user specifies the Audit_Code c. Each User in the org has a unique text field, Audit_Code _e, that is used to automatically assign the correct user to the Account's Auditor_c field.
What should be changed to most optimize the code's efficiency?
Choose 2 answers
Answer: A,B
Explanation:
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.
