A SOC analyst confirms that an employee entered credentials into a phishing site and that the mailbox now shows a new forwarding rule sending messages to an external address. The account is still signed in on a laptop and a mobile phone. What is the best next 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
Wait for the user to log out naturally before taking action.
Delaying action gives the attacker more time to use stolen sessions and access additional mail.
B
Best answer
Revoke active sessions and force a password reset for the account.
This removes the attacker’s current access path and prevents reuse of the compromised credentials.
C
Distractor review
Archive the mailbox and close the ticket after notifying the user.
Archiving does not stop compromise and ignores active suspicious access and mailbox manipulation.
D
Distractor review
Delete the forwarding rule only and consider the incident closed.
The attacker may still have valid sessions or a captured password after the rule is removed.
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 force a password reset for the account. — Revoking active sessions and forcing a password reset are the most appropriate immediate containment actions once credential theft is confirmed. The forwarding rule shows the attacker has already changed mailbox behavior, and the account still has live sessions on multiple devices. Resetting the password alone is not enough if valid tokens remain active. Removing the attacker’s access first limits further abuse and prepares the account for safe recovery. Why others are wrong: Waiting for logout is unsafe because attackers often maintain persistent sessions. Archiving the mailbox does not stop the compromise. Deleting only the forwarding rule addresses one symptom, but not the stolen credentials or any existing active sessions. The attacker could simply recreate the rule or continue accessing the account.
