Salesforce Development-Lifecycle-and-Deployment-Architect - Salesforce Certified Development Lifecycle and Deployment Architect (SP25)

The best practice for writing test classes is to not use SeeAllData and generate data in the test methods. This ensures that the test classes are independent of the data in the org and can run successfully in any environment. Creating test data in production or setting SeeAllData to True can cause unexpected failures or data conflicts.

 Executing all test classes in sandboxes can help identify and fix any errors or failures before deploying to production. Executing selected test classes in production can help reduce the deployment time and avoid running unnecessary tests.

 Using a Change Set or manually replicating the changes in the developer sandbox are both valid approaches to ensure that changes made in production are reflected in the sandbox that the developers are working on. Refreshing the developer sandbox would overwrite any changes made by the developers, and Salesforce-to-Salesforce is not a deployment tool.

The optimal way to store the service centers as technical reference data is to add them to a custom metadata type. Custom metadata types allow you to create, update, and deploy records that are defined by a custom object. Custom metadata types are similar to list custom settings, but they have some advantages, such as being deployable, queryable, and packageable. Hierarchical custom settings are not suitable for storing multiple records of the same type, and defining a new custom object with a picklist field is unnecessary and inefficient.

Tracking effort estimates, actuals, and remaining work can help the developer improve their estimation skills and accuracy, which can benefit the project planning and delivery.

The responsibility of the Technical Architect within a Change Control Board meeting is to approve the upcoming release for deployment into production, as they are the ones who have the authority and expertise to evaluate the quality and readiness of the release2. Option A is not correct, as prioritizing the Salesforce product roadmap with business stakeholders is not a task that is done in a Change Control Board meeting, but rather in a strategic planning session. Option B is not correct, as conducting code reviews for projects in the development phase is not a task that is done in a Change Control Board meeting, but rather in a code review session. Option C is not correct, as troubleshooting deployment errors that occurred during the last release is not a task that is done in a Change Control Board meeting, but rather in a post-deployment review session.

How to test existing functionality to ensure no regressions are introduced is a decision that the Architect should make when planning for releases, as it is part of the quality assurance process and helps to ensure that the new changes do not break the existing functionality. When to test a new UC feature release is also a decision that the Architect should make when planning for releases, as it is part of the release schedule and helps to coordinate the testing activities with the development and deployment activities. Whether Salesforce will wait to upgrade the pod until after a UC release is complete is not a decision that the Architect can make, as it is determined by Salesforce and depends on the release window and the pod assignment. How to roll back to the previous Salesforce release if there are issues is not a decision that the Architect can make, as it is not possible to roll back to a previous Salesforce release once the upgrade is done.
