Properly installing managed packages helps prevent conflicts with customizations made by customers and partners. What functionality should be used to…

The functionality that should be used to set up packages is namespace. A namespace is a unique

identifier that distinguishes one package from another and prevents naming conflicts with other

packages or customizations. A namespace also allows developers to expose their code or

components for use by other developers through APIs or web services. A description is not a

functionality that should be used to set up packages, but a text field that provides information about

the package contents or purpose. A description does not prevent conflicts with other packages or

customizations. Allow sharing is not a functionality that should be used to set up packages, but a

setting that controls whether users can share records owned by other users within their role

hierarchy. Allow sharing does not prevent conflicts with other packages or customizations. Help

setting is not a functionality that should be used to set up packages, but a setting that determines

whether users can access help documentation for standard Salesforce features or custom features

within a package. Help setting does not prevent conflicts with other packages or customizations.
