A sales manager wants to use Dynamics 365 Customer Insights - Journeys to send a follow-up email to all contacts who attended a recent webinar. The webinar attendance data is stored in a custom table in Dynamics 365. Which type of segment should they create to target these contacts?
Dynamic segment
Dynamic segments evaluate conditions in real time, suitable for targeting based on related records.
Deployed segment
Why wrong: Deployed segment is not a valid segment type.
Static segment
Why wrong: Static segments do not automatically update based on changes.
Custom segment
Why wrong: Custom segment is not a standard segment type in Customer Insights - Journeys.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Dynamic segment
A dynamic segment is the correct choice because it automatically updates membership based on real-time data and conditions, such as a custom table recording webinar attendance. This ensures that as new contacts attend webinars, they are automatically included in the segment without manual intervention, making it ideal for targeting contacts based on evolving criteria.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Custom segment is not a standard segment type in Customer Insights - Journeys.
Common exam traps
The trap here is that candidates may confuse 'custom segment' with a segment built from a custom table, but Microsoft's official terminology only recognizes static and dynamic segments, and 'custom' is not a valid segment type.
Detailed technical explanation
Under the hood, a dynamic segment in Dynamics 365 Customer Insights - Journeys uses a query builder that can reference attributes from any entity, including custom tables, and evaluates membership in near real-time via the segment's refresh schedule (e.g., every 15 minutes). This allows the segment to automatically include contacts who have a related record in the custom webinar attendance table, even if that table is not part of the standard out-of-the-box schema. In a real-world scenario, if the custom table includes a 'WebinarDate' field, the dynamic segment can be configured to only include contacts who attended within the last 30 days, ensuring the follow-up email remains timely.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
