Pass the Salesforce Developer Plat-Arch-202 Questions and answers with ExamsMirror

The correct selection is D. Migration order must respect object dependencies. Accounts precede Contacts and Opportunities; Products and Opportunities must exist before Opportunity Line Items; Leads are comparatively independent and can be loaded after the dependent object chain without breaking referential integrity. From a deployment perspective, the same release should be reproducible across environments, with dependencies, metadata/data differences, API behavior, and target-org constraints identified before production. Automation is valuable because it turns deployment knowledge into a controlled process rather than relying on memory or manual reconstruction. The alternatives are less reliable because they do not provide the same controlled handling of metadata, data relationships, validation, or environment-specific dependencies. For this scenario, the decisive point is therefore the platform behavior represented by the selected option (D. Accounts, Contacts, Opportunities, Products, Opportunity Line Items, Leads). 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 A, B. Because regulations prohibit production data in non-production, UC can either mask a production-derived Full sandbox or generate synthetic data with production-like distribution and volume. Both approaches support realistic performance behavior without exposing regulated values. From a testing perspective, the goal is deterministic evidence that the solution behaves correctly under the conditions that matter. Tests should isolate external dependencies, use controlled data, exercise positive and negative paths, and reproduce realistic volume or user behavior where required without making production the first place defects are discovered. The rejected choices either test the wrong layer, introduce live-system dependencies, or detect problems too late to provide the deterministic early feedback expected from a mature test strategy. For this scenario, the decisive point is therefore the platform behavior represented by the selected options (A. Perform data masking on full sandbox after a refresh.; B. Generate mock data that mimics production data shape and volume.). 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, C. Secure pull-request review and automated static security analysis create complementary controls. Human reviewers assess architecture and context, while scanners detect repeatable vulnerability patterns and can block unsafe changes in CI before they reach downstream environments. 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 options (B. Implement a pull request and secure code review.; C. Integrate a static code security analysis tool in the CI/CD process.). 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 A. Checkmarx findings must be reviewed individually. Real vulnerabilities should be remediated; legitimate false positives should be documented with a technical justification and included in the AppExchange security-review submission rather than ignored or mechanically changed simply to produce a zero-warning report. 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 alternatives do not create the same repeatable engineering control: they either postpone defect detection, couple teams unnecessarily, or bypass the package/source model that should govern the change. For this scenario, the decisive point is therefore the platform behavior represented by the selected option (A. Review the Checkmarx errors. If there is no need to fix, mark them as false positive and attach explanation, then submit.). 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 A, B, E. Moving to a single org can reduce duplicated administration, improve collaboration across business units, and make a unified customer view easier. Consolidating processes and data models still requires deliberate harmonization, so those outcomes are not automatic simply because orgs are merged. From a system-design perspective, the decision should minimize unnecessary coupling while preserving clear ownership, scalability, governance, and extensibility. Salesforce architecture is strongest when boundaries reflect real business and technical responsibilities instead of using organizational convenience as the primary design driver. The other options introduce tighter coupling, duplicate governance, or solve a different architectural concern and therefore do not satisfy the stated boundary and ownership requirements. For this scenario, the decisive point is therefore the platform behavior represented by the selected options (A. Lower administration overhead costs.; B. Improved Chatter collaboration across different business units.; E. Easier to get a 360-view of the customer.). 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, C. To catch failures earlier, administrators should run relevant unit tests before configuration changes and make those changes in a controlled admin sandbox before promotion. This shifts validation left and prevents production from becoming the first environment where code/configuration dependencies are exercised. From a testing perspective, the goal is deterministic evidence that the solution behaves correctly under the conditions that matter. Tests should isolate external dependencies, use controlled data, exercise positive and negative paths, and reproduce realistic volume or user behavior where required without making production the first place defects are discovered. The alternatives do not provide equivalent evidence: they either validate only a narrow implementation detail or depend on conditions outside the test ' s control. For this scenario, the decisive point is therefore the platform behavior represented by the selected options (B. Ask administrators to run unit tests before every change.; C. Train the administrators to make their changes in a special " admin changes " sandbox, and then promote to production.). 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. A Metadata API-formatted release artifact should be validated and deployed consistently using the Metadata API deployment mechanism. Mixing source-format and mdapi commands introduces needless conversion risk, and because quick deploy is excluded, the normal deployment must run after successful validation. From a deployment perspective, the same release should be reproducible across environments, with dependencies, metadata/data differences, API behavior, and target-org constraints identified before production. Automation is valuable because it turns deployment knowledge into a controlled process rather than relying on memory or manual reconstruction. The alternatives are less reliable because they do not provide the same controlled handling of metadata, data relationships, validation, or environment-specific dependencies. For this scenario, the decisive point is therefore the platform behavior represented by the selected option (B. Authorize to the Full sandbox org; Validate with sfdx:mdapi:deploy On successful validation, deploy with sfdx:mdapi:deploy). 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 C. When Apex classes logically belong to package B, source ownership should be moved to package B and new package versions created. Second-generation packaging treats versions as deployable states, so component ownership changes must be reflected through properly built and tested versions rather than duplicate class names. 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 rejected choices either rely on manual review alone, use the wrong development abstraction, or introduce custom complexity where Salesforce already provides a source-driven engineering mechanism. For this scenario, the decisive point is therefore the platform behavior represented by the selected option (C. Move the classes of package A to package B and create new package versions.). 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 A, C, D. Direct low-risk production changes still require governance: they should be documented, tested, and incorporated into the downstream development baseline. Production edits do not automatically update lower environments, so failing to synchronize them creates configuration drift and risks later deployments overwriting the change. 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 alternatives either leave production and lower environments inconsistent, increase operational risk, or treat a recurring governance problem as a one-time manual activity. For this scenario, the decisive point is therefore the platform behavior represented by the selected options (A. Minor changes should be thoroughly documented and follow some type of standard cadence.; C. Downstream environments will not be automatically updated when production changes.; D. All changes should still be tested.). 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 C. Source tracking removes much manual change management, but metadata types outside source-tracking coverage still require explicit tracking and deployment planning. Setup changes are not inherently manual if their metadata type is supported. 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 rejected choices either rely on manual review alone, use the wrong development abstraction, or introduce custom complexity where Salesforce already provides a source-driven engineering mechanism. For this scenario, the decisive point is therefore the platform behavior represented by the selected option (C. Changes to components not yet supported by source tracking.). 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.
