A SIEM correlates three failed MFA prompts for a payroll admin account from one IP, a successful login two minutes later from the same IP, and a new mailbox forwarding rule to an external address. What is the best immediate 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
Reset the password and leave the account enabled so the user can keep working.
A password reset helps only if the attacker is blocked from the session. It does not immediately stop any active access tokens or mailbox rule abuse.
B
Best answer
Disable the account and revoke active sessions and tokens.
This is the best immediate containment step because the signs strongly indicate account compromise. Disabling the account stops new authentication, while revoking sessions and tokens cuts off any already-established access that could continue to act as the user. That combination contains the incident quickly and limits further mailbox manipulation, data theft, or privilege misuse while the team investigates logs and confirms scope.
C
Distractor review
Delete the forwarding rule and monitor the account for a few hours.
Removing the forwarding rule addresses only one symptom. If the attacker still has valid access, they can recreate the rule or perform other malicious actions immediately afterward.
D
Distractor review
Wait for the user to confirm the login before taking any action.
User confirmation is useful, but it is too slow when the logs already show suspicious access and mailbox tampering. The priority is containment, not delay.
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: Disable the account and revoke active sessions and tokens. — The strongest immediate response is to disable the account and revoke active sessions and tokens. The log sequence indicates likely account takeover: failed MFA attempts, then a successful login from the same source, followed by mailbox forwarding setup. That means the attacker may already have access even if the password changes later. Revoking sessions removes current access paths, and disabling the account stops additional sign-ins while the security team investigates scope and preserves relevant logs. Why others are wrong: Resetting the password alone may not terminate existing sessions or refresh tokens, so it leaves the attacker room to continue. Deleting the forwarding rule is useful cleanup, but it does not remove the underlying compromise. Waiting for user confirmation is risky because the evidence already supports immediate containment. Security operations should prioritize stopping further misuse first, then validate whether the activity came from the user, a compromised device, or an adversary.
