Implementing a Hub-and-Spoke multi-org strategy by consolidating customer data in a single org, which will be the master of customer data, and using integration strategies to let the LOBs orgs read and write from it is one of the options an architect can recommend to accomplish the customer 360-degree view. This way, the architect can ensure that there is a single source of truth for the customer data, and that the data is consistent and synchronized across the different orgs. Implementing a Single Package multi-org strategy by developing and deploying to all orgs a managed package which reads and consolidates customer 360-degree view from the different orgs is another option an architect can recommend, as it allows the architect to create a reusable and scalable solution that can provide a unified view of the customer data from multiple sources. Implementing a Complete Graph multi-org strategy or migrating from multi-org to single-org strategy are not feasible or optimal options, as they can introduce complexity, cost, or risk to the architecture.

 A single org strategy has the benefits of increased ability to collaborate, centralized data location, and consistent processes across the business. These factors can improve efficiency, data quality, and user adoption. A single org strategy may not allow for tailored implementation or fewer inter-dependencies, as different business units may have different requirements and dependencies.

 Extracting each permission set, committing and merging to source control, and running through CI checks is the best strategy to bring the issue of failing SOQL statements to the developer’s attention earlier. This way, the developers can review the changes made by the administrators, and ensure that they do not break any existing functionality or security rules. Asking administrators to only make changes to profiles instead would not solve the problem, as profiles can also affect SOQL queries. Creating a sandbox refresh strategy to ensure each sandbox is refreshed every day would not prevent the issue from happening, as the changes made by the administrators would still be propagated to the sandboxes. Advising developers to switch to SOSL queries that are more robust instead would not address the root cause of the issue, which is the lack of visibility and control over the permission sets.

Creating transparency by being honest and clear about timing, planning, and obstacles is one of the Scrum principles, as it helps to build trust and collaboration among the team and the stakeholders. Delivering working software is also a Scrum principle, but it does not mean that the software should not be changed if it is working. Respect is another Scrum principle, but it does not imply that a developer should not test the software, as testing is part of the development process. Embracing change is also a Scrum principle, but it does not mean that the scope should change every day, as that would make it impossible to deliver value and quality.

Minor changes should be thoroughly documented and follow some type of standard cadence, as this can help maintain the audit trail and visibility of the changes. All changes should still be tested, even if they are minor, as they can have unexpected impacts on other parts of the system or introduce bugs or security issues. Downstream environments will not be automatically updated when production changes are made, so it is important to have a strategy to keep them in sync and avoid conflicts or overwrites. Minor changes do not need to be documented and can be made at any time is a wrong statement, as it can lead to poor governance and lack of accountability. CI/CD is not required to successfully manage minor changes, although it can help automate and streamline the process. See  Application Lifecycle and Deployment  for more details.

The best deployment tool for UC to use to manage their deployment process in an automated fashion is the Force.com Migration Tool, as it is a command-line tool that uses the Metadata API to deploy components from one org to another, and can be integrated with version control systems and continuous integration servers. Option A is not a good choice, as Workbench is a web-based tool that does not support automation or scripting. Option C is not a good choice, as Change Sets are a point-and-click tool that require manual steps to create and deploy. Option D is not a good choice, as Force.com IDE is a desktop tool that does not support automation or scripting.

 Three advantages of using the SFDX are: can store code on a local machine, or a version control system; can create scratch orgs; and can install application metadata from a central repository. These advantages can help improve the development experience, as they allow developers to work with source-driven development, use ephemeral and configurable environments, and access metadata components from a shared location. Can quickly deploy metadata using Execute Anonymous is not an advantage of using the SFDX, as Execute Anonymous is a feature of the Developer Console that allows running Apex code, not deploying metadata. Can use native Deployment Rollback Tool to quickly revert to prior state is also not an advantage of using the SFDX, as there is no such tool in the SFDX. See [Salesforce DX] for more details.

 Using a Source Control system alongside a multi-sandbox development strategy has several advantages, such as performing code reviews before promoting to a pre-production sandbox, keeping a history of changes made by each developer, and creating a branching strategy that tracks each feature or change separately. Automatically deploying changes from sandbox to production is not an advantage of Source Control, but rather a function of a Continuous Integration tool. Acting as a backup in case of catastrophic data loss is not an advantage of Source Control, but rather a benefit of having a sandbox strategy.

 Refreshing a Partial Copy sandbox every weekend and including an appropriate sandbox template will allow UC to train the users on samples of production data and delete all the data generated during the training session at the end of the week. Loading data using data loader is not necessary if the sandbox template includes the relevant data. Developer Pro sandboxes have limited storage and may not be able to accommodate the data needed for the training.

The partner can use Developer Edition or Partner Developer Edition for development of the managed package. These environments allow the creation of a namespace and the packaging of components into a managed package. Developer sandbox and Developer Pro sandbox do not support these features and are not suitable for developing a managed package.
