Salesforce Certified Marketing Cloud Administrator — Question 8

A Marketing Cloud admin wants to check the status of a Salesforce contact in All Subscribers. The account is connected to their Salesforce org via Marketing Cloud Connect.
Which subscriber key should be used to search for the contact in All Subscribers?

Answer options

• A. Email Address
• B. 18-digit Contact ID
• C. 15-digit Contact ID

Correct answer: B

Explanation

The correct answer is B, the 18-digit Contact ID, as this is the unique identifier used by Salesforce to represent contacts in Marketing Cloud. The other options, Email Address and 15-digit Contact ID, are not suitable for this purpose, as the 15-digit Contact ID is often used for other Salesforce objects and does not provide the necessary uniqueness in this context.
