Not a Standard Profile

CDE.

Sure, I'd be happy to help you out with this question from the "Essentials for New Lightning Experience Administrators" exam!

Profiles are a way to control what users can do in Salesforce, and they determine the objects, fields, and features that each user can access. A standard Profile is one that is provided by Salesforce out-of-the-box and can be used as-is or customized as needed.

Let's take a look at each answer choice:

A. System Administrator - This is a standard Profile in Salesforce and is the most powerful Profile available. Users with this Profile have full access to all objects, fields, and features in Salesforce.

B. Read Only - This is also a standard Profile in Salesforce and is used for users who need to view but not edit data in Salesforce. Users with this Profile can view all objects and fields, but cannot create, edit, or delete any records.

C. Marketing Director - This answer choice is not a standard Profile in Salesforce. It's possible that a custom Profile with this name could be created, but it would not be part of the standard set of Profiles that Salesforce provides.

D. Partner Portal User - This is a standard Profile in Salesforce that is used for external users who need to access certain features of Salesforce, such as Cases or Opportunities. Users with this Profile can access only the objects and features that they need to do their job.

E. Standard Administrator - This is not a standard Profile in Salesforce. It's possible that a custom Profile with this name could be created, but it would not be part of the standard set of Profiles that Salesforce provides.

So, the answer to the question is C. Marketing Director, since it is not a standard Profile in Salesforce.
