Universal Containers (UC) is implementing a governance framework and has asked the Architect to make...

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.
