Explanation:

Multiple triggers on the same object can cause conflicts and performance issues. Multiple unit test failures can indicate poor code quality and lack of maintenance. Duplicated logic across Visualforce pages and Apex classes can lead to inconsistency and redundancy.

Explanation:

To support application lifecycle methodology, you need tools that can help you manage the source code, automate the deployment process, and track the issues and bugs. A version control repository is a tool that allows you to store, track, and collaborate on the source code of your application. A continuous integration tool is a tool that allows you to automate the deployment of your code to different environments, as well as run tests and validations. An issue tracking tool is a tool that allows you to record, monitor, and resolve the issues and bugs that arise during the development and testing phases. A database management system is a tool that allows you to store, manipulate, and query data, but it is not directly related to application lifecycle methodology. A middleware is a software layer that facilitates communication and data exchange between different applications, but it is not directly related to application lifecycle methodology either.

Explanation:

Manually validating change sets before deployment is a recommended practice to avoid possible delays while deploying a change set, as it can help you identify and resolve any errors or dependencies before the actual deployment. Change set performance is not independent of included components, as some components may take longer to deploy than others. Manually creating new custom objects and new custom fields or manually applying the field type changes are not advisable, as they can introduce human errors and inconsistencies between environments. See Deploy Changes with Change Sets for more details.

Explanation:

The best options to enforce code quality in UC’s continuous integration process are to introduce manual code review before deployment to the testing sandbox and to introduce static code analysis before deployment to the testing sandbox. Manual code review can help identify and fix any errors, bugs, or best practices violations in the code. Static code analysis can help check the code quality, complexity, and security using automated tools and standards. Introducing manual code review before deployment to the production org may be too late, as the code may have already caused defects or issues in the testing sandbox. Increasing the size of the testing team assigned to the project may not improve the code quality, as the testing team may not have the skills or authority to review or modify the code. Testing data creation is outside the scope of code quality.

Explanation:

To track Salesforce metadata throughout the development lifecycle across sandboxes and production, the architect should recommend using an AppExchange or third-party tool that is specialized in Salesforce deployment. These tools can provide features such as version control, dependency analysis, automated testing, and rollback capabilities. Using an Excel sheet to track deployment steps and document the SFDX commands is not a reliable or scalable solution, as it is prone to human errors and does not provide any automation or validation. Using ChangeSet to track deployed customizations is also not a good option, as ChangeSet is limited in the types of metadata it can deploy and does not support versioning or dependency management. Using Salesforce SFDX commands to deploy to different sandboxes is a possible solution, but it requires a high level of technical expertise and does not provide a graphical interface or reporting capabilities.

Explanation:

Change sets provide an easy way to deploy related components, as they allow the user to select the components from a list and add them to the change set. They also provide a simple and declarative method for deployment, as they do not require any coding or scripting. Change sets do not provide the ability to deploy a very large number of components easily, as they have a limit of 10,000 components per change set. They also do not provide the ability to track changes to components, as they do not have any version control or history features.

Explanation:

B and D are the correct answers, as Force.com IDE and Force.com Migration Tool are the deployment tools that will support the request of creating a new custom object to track Shipping Containers and making it available globally by all Salesforce instances and further maintained and modified regionally by local administrators. Force.com IDE and Force.com Migration Tool are both tools that use the Metadata API to retrieve and deploy metadata components, such as custom objects, from one org to another. They also allow for selective deployment, meaning that only the components that are needed can be deployed, without affecting the rest of the org. A is incorrect, as Tooling API is not a deployment tool, but an API that provides access to metadata and code, as well as customizing and automating the development process. C is incorrect, as Change sets are not a deployment tool that will support the request, as they are limited to deploying components between connected orgs, and do not allow for selective deployment or regional modifications. You can learn more about these tools in the Deploy Changes with the Force.com Migration Tool and Deploy Changes with the Force.com IDE units on Trailhead.

Explanation:

A and C are the correct answers, as they are the project situations that favor an agile methodology. An agile methodology is a flexible and iterative approach that can accommodate changing requirements, deliver value quickly, and enable frequent feedback and collaboration. A is correct, as a digitization project to update an existing customer-facing process and enable quick adjustments is a situation that requires an agile methodology, as it involves transforming a legacy system, adapting to customer needs, and delivering incremental improvements. C is correct, as an environment with a heavy investment in DevOps capabilities for rapid testing and deployment is a situation that requires an agile methodology, as it enables continuous integration and delivery, as well as quality assurance and automation. B is incorrect, as a project to be executed by a third party, with a fixed and formal scope, budget, and timeline is a situation that favors a waterfall methodology, as it involves clear and stable requirements, contractual obligations, and sequential phases. D is incorrect, as a project with well-defined requirements and complex interactions between front- and back-end systems is a situation that favors a waterfall methodology, as it involves detailed planning, design, and testing, as well as minimal changes and dependencies. You can learn more about this topic in the Agile Basics module on Trailhead.

Explanation:

Integrating an agile issue tracker with software testing and continuous integration tools can provide the following benefits:

Developers can see automated test statuses that commit on a specific user story, which can help them identify and fix any errors or failures quickly.

Developers can use the committed code’s build status directly on the user story record, which can help them track the progress and quality of their work.

Explanation:

The package development model relies on source tracking to automatically track the metadata changes in the package project. However, not all metadata components are supported by source tracking, and some changes may need to be tracked manually. For example, changes to profiles, permission sets, custom metadata types, and custom settings are not supported by source tracking. You can find the list of unsupported components here1. No manual tracking is required for the changes that are supported by source tracking, nor for the changes made via the Setup UI, as they are automatically captured by the package development model.
