❓ Sample Exam Questions
A company is experiencing performance degradation as their Salesforce instance grows to millions of records. Which core competency should they prioritize when hiring a Platform Data Architect?
- A. Expertise in customizing Salesforce Lightning components and React framework integration
- B. Ability to architect and optimize data models that maintain system performance while supporting enterprise-scale growth
- C. Knowledge of Salesforce Service Cloud configuration and omnichannel routing setup
- D. Experience with Salesforce CPQ and Revenue Cloud implementation
A Salesforce administrator is designing a system to handle millions of account records with complex filtering and reporting requirements. What should be the primary focus when planning this implementation?
- A. Ensuring all custom fields are marked as required to maintain data integrity
- B. Implementing query optimization, understanding platform limitations, and designing appropriate database indexes
- C. Maximizing the number of list views to improve data visibility
- D. Increasing the frequency of scheduled report exports to enhance performance
A Salesforce administrator notices that custom reports querying related Account and Opportunity data are running slowly due to complex join operations. Which feature should they implement to optimize query performance?
- A. Configure field-level security policies to reduce data retrieval scope
- B. Deploy denormalized data structures that precompute common field combinations
- C. Enable asynchronous processing for all report scheduling tasks
- D. Implement row-level security filters on the source objects
Your organization uses a custom object to track individual line items for customer orders. Each line item must be permanently linked to its parent order, and if an order is deleted, all associated line items should automatically be removed from the system. Which relationship type best satisfies these requirements?
- A. A Lookup relationship, which allows line items to exist independently if their parent order is deleted
- B. A Master-Detail relationship, which mandates that line items remain connected to their order and enforces automatic deletion of child records when the parent is removed
- C. An External Lookup relationship, which connects your Salesforce data with third-party order management platforms
- D. A self-referential relationship on the Order object to link related orders together
An organization needs to improve Salesforce performance while maintaining access to historical transaction records for regulatory audits. Which approach best addresses this requirement?
- A. Duplicate all records across multiple Salesforce orgs to distribute the storage load evenly
