Explanation
To make sure that all of the Salesforce users log in using the branded login URL after deploying my domain, and give them a grace period for updating their bookmarks, the administrator should set the Redirect policy to Redirect with a warning to the same page within the domain. This will redirectusers who try to log in from
https://login.salesforce.com or another domain to https://nto.my.salesforce.com, and show them a warning message that they need to update their bookmarks. Setting the Login policy or preventing login from
https://login.salesforce.com will not redirect users or give them a warning. Filtering with Form Factor will not affect login URL.

Explanation
To advertise on TV, radio, print, and social under one banner called New Runners and aggregate total statistics for this marketing effort, an administrator should use Parent campaign field on Campaign object. This field allows creating hierarchical relationshipsbetween campaigns by specifying one campaign as parent of another campaign. Parent campaigns roll up statistics from child campaigns such as number of leads generated, amount of revenue won etc. For example, an administrator can create four child campaignsfor TV, radio, print and social ads respectively and link them to one parent campaign called New Runners using Parent campaign field. Junction object, lookup relationship, and master-detail relationship are not features related to Campaign object or hierarchy.

To automate an outbound message, the administrator should use a workflow rule that defines the criteria for sending the message and the actions to perform when those criteria are met. One of the actions available for workflow rules is sending an outbound message to a designated endpoint URL with specified fields as parameters. Process builder, task assignment, and flow builder are not able to send outbound messages directly. References: https://help.salesforce.com/s/articleView?id=sf.workflow_define.htm&type=5

Explanation
Permission sets are a flexible way to grant additional access to users without changing their profiles. To provide access to the lead object for a team of support users, create a permission set that includes the appropriate object and field permissions for leads, and then assign it to the users.
