How Do You Add a Defender for Cloud Apps Alert to a Sentinel Incident?
You have a Microsoft Sentinel workspace that uses the Microsoft 365 Defender data connector. From Microsoft Sentinel, you investigate a Microsoft 365 incident. You need to update the incident to include an alert generated by Microsoft Defender for Cloud Apps. What should you use?
Community Insight
The exam tests whether you can locate the Sentinel feature that adds related alerts to an incident, and the trap is choosing the incident’s Timeline tab or the Defender portal Alerts page instead of the entity side panel’s Timeline card.
This SC-200 question tests how Microsoft Sentinel incident investigation exposes related Microsoft 365 Defender alerts through the entity timeline. The page establishes that to add a Defender for Cloud Apps alert to an existing Sentinel incident, you use the entity side panel’s Timeline card (option A).
A common mistake is selecting the Timeline tab on the Sentinel incidents page or the Alerts page in the Microsoft 365 Defender portal, because neither action adds the Defender for Cloud Apps alert to the Sentinel incident.

Why the Answer Is Correct
Microsoft Sentinel’s supported preview workflow for relating an alert to an incident is to open the incident, select Investigate, choose the relevant entity, and then use the Timeline card in the entity side panel. The Microsoft 365 Defender connector supplies Microsoft Defender for Cloud Apps alerts to the Sentinel workspace, so the alert can be selected there and added to the incident. This is exactly the function described by option A, not a generic incident timeline or portal alert list.Why the Other Options Are Wrong
Option B refers to a Timeline tab on the Sentinel incidents page, but the add-alert control is not a standalone incident-page timeline; it is surfaced through the entity side panel. Option C names the investigation graph, which is where you begin by selecting an entity, but the graph alone is not the add mechanism. Option D, the Alerts page in the Microsoft 365 Defender portal, lets you view Microsoft Defender for Cloud Apps alerts but does not update the Microsoft Sentinel incident with that alert.Community Comment Notes
Several learners, including kabooze and shadowdark83, followed the Microsoft Learn article and concluded that the entity timeline is the path; kabooze wrote “It's A based on this”. nsss summarized the same procedure by saying you need to “go to the entity side panel and then select a timeline card.” IT_Nerd31 argued that the quoted article was being misread, describing the Sentinel investigation view as an Entities tab leading to an entity blade, which is consistent with using the entity side panel rather than the incidents Timeline tab. The debate is mostly about imprecise UI wording, not a different technical workflow.Official Reference
Exam Strategy
When an SC-200 item asks how to add a related alert to a Sentinel incident, follow the Investigate > select entity > entity side panel > Timeline card path rather than choosing a page that only displays alerts. The exam often uses slightly imprecise UI labels, so focus on the functional location where the Add to incident action lives.
Frequently Asked Questions
Why is the Timeline tab on the Sentinel incidents page not the right option?
The supported preview workflow is not a standalone incident Timeline tab; it starts from the investigation graph, where you select an entity and open the Timeline card in the entity side panel.
Can I add the Defender for Cloud Apps alert from the Microsoft 365 Defender Alerts page?
The Defender portal can show the alert, but the requirement is to update the Microsoft Sentinel incident; that is done from the Sentinel entity timeline, not the Defender Alerts page.
