Quick Answer
The three sources to examine are the alert timeline, the email entity page, and the user entity page. This is correct because investigating a malicious link click requires tracing the attack from the initial email through to the user’s actions, and these three sources provide the full chain of evidence: the alert timeline shows related events and context, the email entity page reveals details like sender, recipient, and link analysis, while the user entity page aggregates all user-centric activities and risk indicators. On the MS-102 exam, this tests your ability to scope a phishing incident without jumping to irrelevant data—a common trap is to check the device timeline, but if the user only clicked a link without executing a payload, device-level data may be unnecessary. The incidents page offers a summary but lacks the granular detail needed for scope determination. Memory tip: think “A-E-U” for Alert timeline, Email entity, User entity—the three pillars of link-click investigation.

Correct answer & explanation
Email entity page
To fully investigate a phishing incident, you should examine the alert timeline for related events, the email entity page for email details, and the user entity page for user actions. Device timeline may not be relevant if the user only clicked a link without further action. The incidents page provides a summary but not detailed scope.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
