Salesforce Updated Plat-Arch-202 Exam Questions and Answers by elspeth

The correct selection is C. Major production releases should be avoided during peak commercial periods because unexpected regressions, performance degradation, or integration failures have the greatest business impact then. A release calendar should define blackout windows while retaining a separate hotfix path for genuine emergencies. From a release perspective, approved functionality must be isolated from unfinished work and promoted through a predictable, auditable path. Release calendars, validation, stakeholder approval, rollback planning, and branch discipline reduce the risk that a technically correct change becomes an operational failure during production promotion. The other options do not create a safe production path because they ignore timing, approval, rollback, or branch synchronization requirements. For this scenario, the decisive point is therefore the platform behavior represented by the selected option (C. Avoid releasing near peak business periods.). Applying that rule consistently keeps the implementation aligned with Salesforce-supported lifecycle practices and makes the resulting change easier to review, validate, and operate across environments.

The correct selection is D. Package development is optimized for temporary scratch orgs containing the package under development and only its required dependencies. This keeps the workspace isolated, fast, reproducible, and aligned with source-driven modular development rather than recreating the entire enterprise org. From a build perspective, the implementation should be source-driven, reviewable, automatable, and modular. Engineering controls such as version control, package boundaries, static analysis, coding standards, and isolated development environments reduce defects early and make changes easier to understand, test, and promote. The remaining options are weaker because they address symptoms after code is written instead of improving the build process through automation, modularity, and explicit development standards. For this scenario, the decisive point is therefore the platform behavior represented by the selected option (D. A scratch org with the package code that will be changed and its dependencies.). Applying that rule consistently keeps the implementation aligned with Salesforce-supported lifecycle practices and makes the resulting change easier to review, validate, and operate across environments.

The correct selection is D. A complete rollback must restore previously existing metadata and remove components introduced by the failed release. A pre-release baseline plus destructiveChanges.xml for newly added components gives a reproducible reverse deployment; simply redeploying the old metadata does not automatically delete new components. From a release perspective, approved functionality must be isolated from unfinished work and promoted through a predictable, auditable path. Release calendars, validation, stakeholder approval, rollback planning, and branch discipline reduce the risk that a technically correct change becomes an operational failure during production promotion. The rejected alternatives weaken release control by mixing development states, skipping required validation, or treating production promotion as an ad hoc administrative task. For this scenario, the decisive point is therefore the platform behavior represented by the selected option (D. Create a sandbox from production to take the backup of existing metadata. To roll back deployment, use destructivechanges.xml to delete new components and then Deploy again to production using metadata from this sandbox.). Applying that rule consistently keeps the implementation aligned with Salesforce-supported lifecycle practices and makes the resulting change easier to review, validate, and operate across environments.

The correct selection is B. After a sandbox refresh, production-oriented external identifiers can point to invalid records in the UAT integration landscape. A post-refresh process should transform those identifiers to a known UAT-safe mapping so test orchestration remains internally consistent and cannot accidentally target production systems. From an operating perspective, production stability depends on disciplined incident handling, environment synchronization, backup/recovery, observability, and control of configuration drift. Emergency actions can be faster than normal releases, but they still require traceability and must be reconciled back into the managed development baseline. The other options are weaker because they either expose production to unnecessary risk or do not reconcile the operational change back into the governed lifecycle. For this scenario, the decisive point is therefore the platform behavior represented by the selected option (B. In the post refresh plan, modify external ids to a known valid set of values for UAT.). Applying that rule consistently keeps the implementation aligned with Salesforce-supported lifecycle practices and makes the resulting change easier to review, validate, and operate across environments.
