Universal Containers needs to synchronize data between Salesforce and an external financial system. How can a system administrator accomplish this?

The use of an external ID field to match records between Salesforce and an external financial system is an effective approach for data synchronization. An external ID is a unique identifier for a record as it exists outside of Salesforce. By utilizing this field, a system administrator can ensure that records in Salesforce accurately correspond to those in the financial system, allowing for organized and accurate updates.

When synchronizing data, it's crucial to maintain data integrity and consistency. The external ID facilitates this by allowing the system to find the correct records in the external system and map them accordingly. This method is particularly useful during data upsert operations, where you need to either create new records or update existing ones based on the external identifiers.

Using external IDs simplifies the matching process, reduces the risk of data duplication or mismatches, and improves the efficiency of the synchronization operation overall. Furthermore, it handles various data tasks, such as imports or exports, ensuring that the correct data is aligned between both systems without requiring back-and-forth manual intervention.

The other options provided do not offer as robust a solution for data synchronization. For instance, the Excel connector may not handle large datasets efficiently, while the data loader is primarily used for importing or exporting data in bulk but lacks the specific matching capability provided by
