What a journey needs before it can go live: an entry source with a filter and schedule, Journey Settings for contact entry and the default email address, validation and testing, and why a running journey changes only through a new version.

- Certification: Salesforce Marketing Cloud Engagement Foundations
- Exam section: Email Sending and Journeys
- Study guide: https://www.certifyforce.com/study-guide/marketing-cloud-engagement-foundations

**Official exam objective:**

> Outline the necessary configurations to activate a journey and configure entry criteria for a successful activation.

## What the exam expects

- Configure an entry source so that only the intended contacts enter, and choose how often it admits them.
- Pick the contact entry mode that matches a business rule, and know where the mode can't be set.
- Choose the default email address for a journey and predict what happens when the entry data holds more than one email field.
- Explain what validation checks, when it runs and what it can't catch, and why testing follows it.
- Change a running journey with a new version.
- Key terms: **entry source** (where contacts entering a journey come from); **contact entry mode** (when a contact may enter again); **default email address** (which stored address receives journey email); **validation** (the check that the journey's components are configured correctly); **journey version** (a separate copy of the journey you edit and activate).
