The field attribute that should be selected are Unique and External ID. Unique means that the field will not allow duplicate values. External ID means that the field can be used as a foreign key for data imports and upserts. Option B is incorrect because Required means that the field must have a value and cannot be left blank, which is not necessary for this requirement. Option D is incorrect because Text (encrypted) means that the field will store sensitive data in an encrypted format, which is not necessary for this requirement.

The best solution to enable reps to see and access the most-used components from anywhere within the app without leaving the page they are working on is Utility bar. This is a footer that can be added to any Lightning app and can contain tools such as history, notes, or softphone. Favorites, home page, and global actions are not solutions that provide access to components from anywhere within the app. See [this article] for more information on Utility bar.

C: Setting the component visibility based on an advanced filter type, using the contact field(s) to define dynamic criteria, allows displaying information relevant to specific account conditions without needing user interaction.References:

 Partial Copy is the type of testing environment that the app builder should create to use a sandbox template for Accounts, Projects, and Project Milestones. According to the Salesforce documentation, “Partial Copy sandboxes copy your production org’s configuration (metadata) and some of your production org’s data as defined by a sandbox template.” Developer, Developer Pro, and Scratch Org are not types of testing environments that support sandbox templates.
