Development-Lifecycle-and-Deployment-Architect Exam Dumps - Salesforce Developer Questions and Answers

The architect should recommend backing up the existing metadata using the ANT Migration Tool. To roll back deployment, deploy again to production using backed up metadata. This strategy allows the team to restore the previous state of the production org in case of any issues with the deployment. Creating a sandbox from production to take the backup of existing metadata is not necessary and may take longer time. Using destructivechanges.xml to delete new components is not a reliable way to roll back deployment, as it may not remove all the dependencies and references. Manually deleting new components is also not a feasible option, as it may be error-prone and time-consuming.

A full sandbox would be appropriate for diagnosing reports of poor performance when accessing certain Visualforce pages, as it provides a complete copy of the production data and metadata, which allows the developers to replicate and troubleshoot the issue in a realistic environment. A partial copy sandbox would not be appropriate, as it only provides a sample of the production data, which may not reflect the actual volume and complexity of the data that affects the performance. A developer sandbox would not be appropriate, as it only provides a copy of the production metadata, but not the data, which makes it impossible to test the performance of the Visualforce pages with real data. A developer pro sandbox would not be appropriate, as it also only provides a copy of the production metadata, but not the data, which makes it impossible to test the performance of the Visualforce pages with real data.

A requirement traceability matrix is a project artifact that maps each requirement to its corresponding test cases, ensuring that all requirements are covered by testing. User acceptance test scripts are the actual steps to execute the test cases, not the artifact that links them to the requirements. Testing strategy and test execution plan are high-level documents that describe the overall approach and schedule for testing, not the specific mapping of requirements and test cases.

Mock objects are needed when writing test classes to simulate the behavior of real objects or external services that are not available or accessible in the test context. Using a Mock allows the test class to bypass the dependencies of other objects, methods, state, or behaviors, and therefore, the developer has total control of their own code. This is especially useful when the code makes an HTTP callout, as the test class cannot actually call an external web service. A Mock is needed to provide a fake response for the HTTP callout. A Mock is not needed for the classes that extend the batchable interface, as the test class can use the Test.startTest and Test.stopTest methods to execute the batch jobs synchronously. A Mock is not a shortcut for bypassing long running processes, as the test class should still test the functionality and performance of the code.

Utilizing Heroku Connect to provide test class data is not a recommended method of creating test data in Salesforce, as it can introduce unnecessary complexity and dependency on an external system. Referencing data from middleware directly within your test class is also not a good practice, as it can make your test class unreliable and dependent on the availability of the middleware. Hosting a mock endpoint to produce sample information from an endpoint and loading a CSV as a static resource and referencing it in a test class are both valid methods of creating test data in Salesforce, as they allow you to isolate your test class from external factors and ensure consistent results. See Create Test Data for Apex Tests for more details.

 Scratch orgs are the best development environments for the package development model, as they allow developers to start a new project, start a new feature branch, or start automated testing in a disposable and configurable org. Scratch orgs also track all the changes automatically and can be easily integrated with version control systems. Scratch orgs can coexist with other models, such as the org development model, but this is not the main reason to start using them. Dev sandboxes are not suitable for the package development model, as they are not within the code deployment path and they do not support source-driven development.

To reduce deployment time, UC can use the following strategies:

Use recent deployment validations and the quick deploy feature, which can allow them to skip the validation step in production and deploy the changes faster, if they have already validated the changes in a sandbox within the last four days.

Specify the test to run by using RunSpecifiedTests test level, which can allow them to run only the tests that are relevant to the components being deployed, instead of running all the tests in the org.

The Tooling API is the best choice for the team that wants to use SOQL queries to retrieve and make changes to smaller pieces of Salesforce metadata through their Java application. The Tooling API provides access to metadata objects such as Apex classes, triggers, workflows, validation rules, custom objects, and fields. It also supports CRUD operations, as well as executing anonymous Apex code. The other APIs are not suitable for this use case, as they either deal with larger metadata components (Metadata API), user interface components (User Interface API), or data records (Any Salesforce API).

The best option for UC is to refresh Stage now, and do not refresh UAT. This way, Stage will be on the preview instance and UAT will not. This will allow UC to test their application on both the current and the next Salesforce version, and ensure that they can release on the current version without any issues. Option B is incorrect because it is not necessary to check the Sandbox Preview Guide or refresh and redeploy to UAT. Option C is incorrect because it is too late to work with support to get on the preview instance after the cutoff dates. Option D is incorrect because it will result in both Stage and UAT being on the same version, which will not allow UC to test their application on the next Salesforce version.

This is the correct answer because Salesforce prohibits stress testing against production because it is a shared environment that hosts multiple customers and tenants. Stress testing against production may affect the performance and availability of the Salesforce service for other customers and violate the terms of service. Stress testing should be done in a sandbox or a developer edition org that is isolated from production.
