SP System Architecture and Design 3

Question 1

An architect is designing a solution where multiple business units share one Salesforce org but must have completely isolated data visibility. Which feature is the foundation of this design?

Accepted Answer

Role Hierarchy with OWD set to Private

Answer

Setting Organization-Wide Defaults (OWD) to Private on critical objects ensures no cross-unit data leakage, with the role hierarchy as the baseline access model.

Question 2

A client requires that certain Salesforce fields are encrypted at rest and that only specific users can view the plaintext values. Which feature meets this requirement?

Accepted Answer

Shield Platform Encryption

Answer

Shield Platform Encryption encrypts data at rest in the database and enforces decryption access via the 'View Encrypted Data' permission.

Question 3

When designing a high-volume case management system, which approach best avoids record locking contention on a shared counter field (e.g., daily case count)?

Accepted Answer

Replace the counter with an aggregate SOQL query at read time

Answer

Computing aggregates at read time with SOQL COUNT() eliminates write-time locking contention entirely.

Question 4

A Salesforce implementation uses a large number of custom metadata types. What is a key architectural advantage of Custom Metadata over Custom Settings?

Accepted Answer

Custom Metadata records are deployable as metadata and included in packages

Answer

Custom Metadata records are true metadata and can be deployed via change sets, Salesforce DX, and packages — unlike Custom Settings data.

Question 5

An architect needs to design a solution where an external system must initiate a long-running Salesforce process and receive a callback when complete. Which pattern is most appropriate?

Accepted Answer

External system calls REST to enqueue, Salesforce sends Outbound Message on completion

Answer

An async enqueue-and-callback pattern (REST to start, Outbound Message or Platform Event to notify) avoids timeout constraints on long-running processes.
