The definitive credential for architects designing scalable, high-performance data solutions on the Salesforce Platform.

At a Glance

Who Should Take This

• The Aspiring Application Architect: Professionals checking off a mandatory requirement for the Application Architect pyramid.
• The Data Strategist: Architects who manage Large Data Volumes (LDV) and need to ensure system performance doesn’t degrade as the org grows.
• The Integration Lead: Senior developers or consultants responsible for complex data migrations and multi-system synchronization.
• The Compliance Officer: Technical leads tasked with implementing Data Governance, GDPR compliance, and Shield Platform Encryption.

What You’ll Prove

This exam shifts away from simple administration and focuses on architectural trade-offs. You aren’t just configuring; you are deciding which data structures will survive 100 million records without locking the system. * You can design scalable data models using Standard, Custom, External, and Big Objects based on specific business requirements.

• You can mitigate performance risks like Data Skew and Record Locking by applying advanced indexing and sharing strategies.
• You can architect enterprise-grade Master Data Management (MDM) solutions to maintain a single source of truth across systems.
• You can implement robust Data Governance frameworks that balance accessibility with strict global privacy regulations.
• You can execute large-scale Data Migrations using ETL tools while respecting API limits and ensuring data integrity.

Suggested Study Path

1. Master the Trailhead Trailmix: Complete the official Architect Journey: Data Architecture trailmix to cover the fundamental documentation.
2. Review the Decision Guides: Read the Salesforce Architect Decision Guides specifically for Data and Sharing to understand when to choose one tool over another.
3. Lab the Edge Cases: Create Big Objects and simulate Parent-Child Data Skew in a developer edition to see the performance impact firsthand.
4. Learn the Tools: Study the specific capabilities and limits of the Bulk API, Dataloader.io, and enterprise ETL patterns.
5. Simulate the Scenario: Take high-quality practice exams to get used to the long, scenario-heavy question format that tests “best fit” rather than just “correct” answers.

Watch Out For

• The “External” Trap: Don’t default to Salesforce Connect or External Objects for everything; know exactly when the overhead and latency are justified versus native storage.
• Sharing Calculation Overhead: Understand that complex Data Models impact Sharing Rules. Adding a relationship isn’t just about data; it’s about the background calculation engine.
• Big Object Limitations: Remember that Big Objects only support a subset of features—no standard reports, no triggers, and very specific SOQL requirements.
• Data Skew Denial: Look out for scenarios involving “10,000+ child records.” This is a classic trigger for questions about Account Skew or Ownership Skew.

Stop worrying about the 58% passing score and start worrying about your record locking errors. If you can handle a 10-million-row migration without crashing the org, you’re ready.
