SAA Data Architecture & Management 3

Question 1

A company's Salesforce org is experiencing slow page loads on the Account object with 10 million records. Which strategy most directly improves query performance without reducing record count?

Accepted Answer

Create skinny tables on the Account object via Salesforce Support

Answer

Skinny tables contain a subset of fields and exclude soft-deleted records, enabling faster queries on large objects like Account.

Question 2

Which of the following is NOT a valid Salesforce data migration strategy?

Accepted Answer

Use SOQL queries to push data from source org to target org directly

Answer

SOQL is a query language for reading data within Salesforce and cannot directly push data to another org; data migration requires extract, transform, and load tools.

Question 3

A Salesforce architect needs to retain 10 years of transaction history for compliance without impacting org performance. What is the best solution?

Accepted Answer

Use Big Objects to store historical transaction data

Answer

Big Objects provide a scalable way to store billions of compliance records natively in Salesforce without affecting performance of standard objects.

Question 4

What happens when a record lock conflict occurs during a Salesforce DML operation in Apex?

Accepted Answer

A DmlException is thrown immediately

Answer

When a record lock cannot be obtained, Salesforce throws a DmlException with the UNABLE_TO_LOCK_ROW error, and the entire transaction must handle the exception.

Question 5

Which field type in Salesforce is automatically indexed by the platform?

Accepted Answer

External ID fields

Answer

External ID fields are automatically indexed by Salesforce, which is why they are commonly used as upsert keys and in WHERE clause filters for performance.
