Exhibit
Microsoft 365 audit trail for user amaya@corp.example: 09:41 User clicked link from external message and signed into a lookalike portal 09:42 OAuth consent granted to app 'ExpenseReport-Helper' scopes=Mail.Read, offline_access, User.Read 09:44 Inbox rule created: if subject contains 'invoice' then forward to finance-relay@external.example 09:46 Refresh token issued from unfamiliar IP 203.0.113.88 09:51 Admin deleted inbox rule 09:52 Password changed successfully
Based on the exhibit, what is the most important next IR action?
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
Change the password again and monitor the mailbox for a few days.
A second password change does not revoke the malicious app consent or invalidate all active tokens. Monitoring alone leaves a persistence mechanism in place, so the attacker may still be able to access mail through OAuth grants or existing refresh tokens.
B
Best answer
Revoke active sessions and OAuth consent grants for the account.
The password has already been changed and the inbox rule removed, but the audit trail shows an OAuth consent grant and a refresh token issued from an unfamiliar IP. Those tokens can continue to authorize access even after a password reset. Revoking active sessions and removing the malicious consent closes the persistent access path.
C
Distractor review
Restore the deleted inbox rule from backup to preserve evidence.
Restoring the inbox rule would immediately recreate the malicious forwarding behavior and increase the risk of additional data loss. Evidence should be preserved through logs and exports, not by reintroducing the compromise artifact.
D
Distractor review
Close the incident because the forwarding rule was removed.
Removing one malicious rule does not end the incident. The OAuth consent grant and refresh token can still provide ongoing access after the password change, so the account is not yet fully remediated.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Revoke active sessions and OAuth consent grants for the account. — The most important next step is to revoke active sessions and remove the OAuth consent grants. The attacker already created an inbox rule and obtained token-based access through a malicious consented app, so a password change alone is not sufficient. In incident response, you must eliminate the persistent access mechanism, not just remove one visible symptom. Why others are wrong: A leaves OAuth-based persistence intact. C would recreate the malicious forwarding rule and risk additional exfiltration. D mistakes cleanup of one artifact for full remediation, but the refresh token and delegated app permissions can still be active.
