Quick Answer
The answer is isolate the device, delete the email from the user’s mailbox, and investigate the incident. These three actions are available directly from the incident page in Microsoft 365 Defender because the page is designed as a centralized triage hub for correlated alerts, allowing you to take immediate containment steps—like isolating an endpoint or removing a malicious email—and then pivot into deeper investigation without leaving the interface. On the MS-102 exam, this question tests your practical knowledge of the Defender portal’s incident workflow, often appearing as a “select three” scenario where common distractors include resetting a user’s password or blocking a URL, which are not native actions on the incident page. A useful memory tip is to think of the incident page as a “contain and explore” toolkit: you can stop the threat (isolate device), remove the payload (delete email), and dig deeper (investigate), but you cannot perform identity or network-level changes from that single view.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
