A customer service application shows the same session ID being used from two countries within five minutes. The legitimate user did not report a password change, but an order shipping address was modified successfully without reauthentication. What attack pattern is most likely?
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
Broken authentication, because the application failed to verify the user again.
Authentication weaknesses may contribute, but the core clue is reuse of a valid session identifier. That points more specifically to session abuse than to a generic login failure.
B
Best answer
Session abuse, because a stolen or replayed session token allowed unauthorized actions.
Session abuse is the best fit when an attacker reuses a valid token or session ID to impersonate a user. The address change without reauthentication strongly suggests the attacker hijacked an active session instead of successfully guessing a password.
C
Distractor review
Cross-site request forgery, because the attacker may have tricked the browser into sending a request.
CSRF usually relies on a victim’s browser being tricked into making a request while already authenticated. It does not explain the same session ID appearing from two distant locations unless a token was actually stolen.
D
Distractor review
Credential stuffing, because the account was likely accessed using reused passwords.
Credential stuffing involves automated login attempts using leaked credentials. Here, the evidence shows an active session being reused, which is different from successful password-based authentication.
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: Session abuse, because a stolen or replayed session token allowed unauthorized actions. — Session abuse is the best answer because the evidence shows unauthorized use of an existing authenticated session. A valid session ID appearing from two countries, followed by a sensitive change without prompting for credentials, strongly suggests token theft, replay, or hijacking. The attacker is bypassing authentication by abusing the session itself rather than logging in normally. Why others are wrong: Broken authentication is too broad and does not specifically explain a reused session token. CSRF can trigger unwanted actions, but it usually occurs from the victim’s own browser, not from a second geographic location using the same session ID. Credential stuffing is a password attack and does not match the evidence of session reuse.
