A SOC analyst confirms that a user entered corporate credentials into a fake sign-in page. Mailbox logs now show a new forwarding rule sending messages to an external address, and the attacker may still have an active session. Which two actions should the analyst take first to contain the account compromise? Select two.
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.
Best answer
Reset the user's password and require a fresh authentication challenge.
Correct because changing the password removes the attacker’s known credential value and helps break direct password reuse. Requiring a fresh authentication challenge also helps ensure the next login is tied to the legitimate user rather than a stolen session.
Best answer
Revoke active sessions and invalidate existing refresh tokens.
Correct because a stolen session can remain valid even after the password changes. Revoking sessions and tokens cuts off the attacker’s current access path and is one of the fastest ways to stop mailbox abuse.
Distractor review
Delete the mailbox and create a new user account.
Incorrect because deleting the mailbox is destructive and unnecessary for initial containment. The organization would lose data and evidence before preserving or reviewing what happened.
Distractor review
Disable all external email delivery for the entire organization.
Incorrect because that would be highly disruptive and far broader than needed. The incident is limited to one compromised account, so organization-wide shutdown is not the least disruptive containment choice.
Distractor review
Wait for the user to confirm whether the message was legitimate before acting.
Incorrect because the SOC already has enough evidence of compromise. Delaying containment gives the attacker more time to exfiltrate mail or abuse the account.
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: Reset the user's password and require a fresh authentication challenge. — The best first actions are to reset the password and revoke active sessions or tokens. Together, those steps remove the attacker’s known credential and terminate access that may still be valid through existing authentication artifacts. In a mailbox compromise, stopping current access quickly matters more than cleanup tasks such as removing forwarding rules, because the attacker can continue reading or sending mail until access is cut off. Why others are wrong: Deleting the mailbox or shutting down email organization-wide is unnecessarily destructive and disruptive for an incident that affects one account. Waiting for user confirmation is too slow once compromise is already verified. Those actions do not contain the attacker as effectively as password reset and session revocation.
