Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
In a regulated payment environment, a user reports approving an unexpected OAuth consent prompt for an app named 'Invoice Reader'. The app now has mailbox read permissions. What should the incident responder do first? During detection and analysis, which decision is most defensible? which action best reduces risk without losing evidence?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Ignore it if MFA is enabled
MFA does not stop an already granted OAuth app permission.
B
Distractor review
Delete all emails from the mailbox
Deleting mail destroys evidence and may not remove access.
C
Distractor review
Only reset the user's Windows password
Password reset alone does not remove the malicious app consent.
D
Best answer
Revoke the app grant, review mailbox access, and identify other users who consented
OAuth consent abuse can persist without password access; revoking grants and scoping exposure contains the incident. In detection and analysis, responders need action that reduces risk while preserving the investigation record.
Common exam trap
Common exam trap: answer the scenario, not the keyword
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.
Technical deep dive
How to think about this question
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.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
