Practice Exam Questions — Salesforce Application Architect
Scenario-based questions reflecting the style and difficulty of the actual Salesforce Application Architect exam. Updated for Winter '26.
Q1. Universal Containers needs to share records with users based on a related field value, not the role hierarchy. What is the correct sharing mechanism?
A) Manual Sharing
B) Criteria-Based Sharing Rules
C) Role Hierarchy
D) Apex Managed Sharing with a custom Share object
► Show Answer
✓ Correct: B — Criteria-Based Sharing Rules share records with a group or role based on field values (criteria) — independent of record ownership or role hierarchy. For very dynamic or complex criteria, Apex Managed Sharing is used.
Q2. What is the recommended approach for integrating a high-volume external system with Salesforce without overwhelming API limits?
A) Direct REST API calls on every external transaction
B) Middleware integration platform (e.g., MuleSoft) with event-driven architecture — batch or stream records to Salesforce using Bulk API 2.0 for high volumes
C) Bi-directional trigger sync on every record save
D) Use Flow to poll the external system every minute
► Show Answer
✓ Correct: B — High-volume integrations should use Bulk API 2.0 for batch operations and a middleware layer (MuleSoft, Boomi, Informatica) to manage rate limiting, retry, and error handling. Avoid per-record synchronous calls at high volume.
Q3. Universal Containers needs to store confidential salary data in Salesforce visible only to HR. What is the MOST appropriate architecture?
A) Store salary in a custom text field with a Profile-level FLS restriction
B) Store salary in a separate custom object with a private OWD and share only with HR users via a role or sharing rule
C) Encrypt the field in the page layout
D) Store salary as a File attachment with restricted sharing
► Show Answer
✓ Correct: B — The most restrictive and auditable approach combines a private OWD (no default access) with explicit sharing to the HR role. FLS alone restricts field visibility but doesn't prevent API access or report visibility for those with object access.
Q4. Which Salesforce capability allows an Application Architect to test a proposed data model at scale before building it?
A) Sandbox with sample data
B) Salesforce Optimizer report
C) Schema Builder with validation rules preview
D) A Proof of Concept (PoC) org with representative data volume and query profiling using the Developer Console Query Plan tool
► Show Answer
✓ Correct: D — Before committing to a data model, architects should test with representative data volumes in a sandbox, using the Query Plan tool in Developer Console to verify index usage and query selectivity at scale.
Q5. Universal Containers wants Salesforce to be the authoritative source for customer data. What integration pattern achieves this?
A) Event-driven integration where Salesforce publishes changes as Platform Events
B) Batch export of all Salesforce data to external systems nightly
C) External systems push changes to Salesforce; Salesforce pushes changes to external via outbound messaging or Platform Events
D) Both B and C are required
► Show Answer
✓ Correct: C — Master data management with Salesforce as the system of record means: external changes flow IN to Salesforce (inbound); Salesforce changes flow OUT to downstream systems (outbound via Platform Events, CDC, or outbound messaging).
Q6. What is the role of the "Enterprise Architecture" principle of "Loose Coupling" in Salesforce design?
A) Minimise the number of objects and fields in the data model
B) Ensure components interact via well-defined interfaces (APIs, events) rather than direct code dependencies, enabling each part to change independently
C) Use only declarative tools and avoid Apex
D) Keep all business logic in a single Apex class
► Show Answer
✓ Correct: B — Loose coupling means components communicate through APIs or events rather than tightly coupled code calls. In Salesforce, this means using Platform Events, Invocable Actions, or REST APIs as integration points rather than direct class-to-class dependencies.
Q7. Which Salesforce architecture pattern is best for ensuring all business-critical processes complete even if Salesforce is temporarily unavailable?
A) Synchronous API calls with retry logic
B) Event-driven architecture with a durable message queue (e.g., Kafka or MuleSoft Anypoint MQ) that stores events until Salesforce is available
C) Increase Salesforce API limits to prevent downtime
D) Use Bulk API which has 100% SLA
► Show Answer
✓ Correct: B — Durable messaging queues (MuleSoft Anypoint MQ, AWS SQS, Kafka) absorb events during Salesforce maintenance windows and replay them when available. This decouples the publishing system's availability from Salesforce's.
Q8. Universal Containers has 15 Salesforce orgs across different business units. They want unified customer 360. What is the recommended architecture?
A) Merge all orgs into one Salesforce org
B) Implement a master data hub (Salesforce Customer 360 Data Manager or MuleSoft API-led connectivity) to synchronise and reconcile customer data across orgs
C) Build custom reports in each org and consolidate in Excel
D) Use Salesforce Connect to link all orgs together
► Show Answer
✓ Correct: B — Multi-org environments need a master data management strategy. Customer 360 Data Manager or MuleSoft creates a golden customer record by reconciling data across orgs, enabling a single authoritative view without forcing a costly org merge.
Q9. What does the "Governor Limit" concept imply for Application Architecture?
A) Salesforce limits the number of users who can be licensed
B) Salesforce enforces execution limits per transaction, requiring architects to design for bulkification, async processing, and distributed load across transactions
C) Code size is limited to 1MB per Apex class
D) SOQL can only be used in Apex classes, not in Flows
► Show Answer
✓ Correct: B — Governor limits exist to ensure multi-tenancy fairness. Architects must design for: bulkified Apex triggers, async processing via Batch/Queueable for heavy operations, and splitting large processes across transactions.
Q10. Universal Containers needs to ensure a custom object can store up to 10 million records with sub-second query times on 3 filter fields. What must an architect consider?
A) Use Salesforce Reports for all queries
B) Design with selective filter fields, request custom indexes from Salesforce, and consider skinny tables for the most critical query patterns
C) Set OWD to Private to speed up queries
D) Use External Objects instead of native objects
► Show Answer
✓ Correct: B — At 10M records, architects must: ensure filter fields are selective (<10%), request custom indexes via Support, and for critical query paths, request skinny tables. Formula fields in WHERE clauses should be replaced with physical fields.
Q11. Which Salesforce feature allows bi-directional data sync between Salesforce and an external CRM without custom code?
A) Apex REST endpoints with polling
B) Salesforce Connect with an OData or custom adapter — or MuleSoft's Salesforce Connector
C) Workflow Rules with outbound messages
D) Scheduled Batch Apex with callouts
► Show Answer
✓ Correct: B — Salesforce Connect enables real-time, in-place access to external data as External Objects. For true bi-directional sync (write back to the external system), MuleSoft or an OData-compliant adapter is the preferred approach.
Q12. An Application Architect must choose between a Master-Detail and a Lookup relationship. The child records must always have a parent and parent deletion should clean up children. Which relationship is correct?
A) Lookup with a required field
B) Master-Detail
C) Hierarchical relationship
D) Indirect lookup
► Show Answer
✓ Correct: B — Master-Detail enforces the required parent (child cannot exist without it) and cascades deletes. Lookup relationships allow orphaned children (null parent) and do not cascade deletes natively.
Q13. Universal Containers processes 500,000 records nightly via Batch Apex. The batch takes 8 hours. How should an architect reduce the runtime?
A) Increase the batch size to 2,000
B) Parallelise by splitting the workload into multiple concurrent Batch Apex jobs with non-overlapping query filters, and optimise the SOQL with selective indexes
C) Switch to a synchronous Apex process
D) Run the batch during business hours instead
► Show Answer
✓ Correct: B — Batch Apex jobs run serially within a single job but you can launch multiple concurrent Batch jobs with non-overlapping data ranges (e.g., by record Id ranges or custom status). Also optimise query selectivity to reduce rows processed.
Q14. What is the role of "Event-Driven Architecture" (EDA) using Platform Events in Salesforce?
A) Platform Events replace all Apex triggers
B) Platform Events decouple publishers and subscribers — the publishing system fires an event without knowing who consumes it, enabling scalable, loosely coupled integrations
C) Platform Events are used only for external system notifications
D) Platform Events eliminate the need for APIs
► Show Answer
✓ Correct: B — Platform Events implement EDA: a publisher fires an event record; any number of subscribers (Flows, Apex triggers, external systems via CometD) can consume it independently. This decouples systems and enables fan-out patterns.
Q15. Universal Containers wants to govern which Salesforce components can be deployed to production without going through the standard Salesforce deployment pipeline. What should an architect recommend?
A) Allow all admins to deploy using change sets
B) Implement a formal DevOps process with Salesforce DX (scratch orgs, version control, CI/CD pipeline, and deployment gates via code review and automated testing)
C) Restrict all deployments to sandbox only
D) Use Permission Sets to block deployment access
► Show Answer
✓ Correct: B — Enterprise Salesforce governance requires a DevOps pipeline: Git-based source control (Salesforce DX), CI/CD tooling (Copado, Gearset, GitHub Actions), automated test runs in scratch orgs, and deployment gates that require test coverage and review.
