Full question →easymultiple choiceObjective-mapped
Employees in a lobby report that their phones automatically connected to a wireless network named "CorpWiFi." Soon after, they were prompted to sign in through a web page that did not look like the normal company portal. What attack 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
Bluetooth pairing attack
Bluetooth pairing attacks target Bluetooth connections, not Wi-Fi networks and captive portals. The prompt is describing wireless LAN behavior instead.
B
Best answer
Evil twin
An evil twin is a rogue wireless access point that imitates a legitimate SSID so victims connect to it by mistake. The fake network name and suspicious sign-in page strongly suggest a malicious clone of the real Wi-Fi.
C
Distractor review
NFC relay attack
NFC relay attacks involve near-field communication and can extend short-range card or device interactions. They do not match a Wi-Fi network connection and web login page.
D
Distractor review
MAC flooding
MAC flooding targets switch tables by overwhelming them with addresses. The scenario focuses on a fake wireless network, not switch table exhaustion.
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: Evil twin — The correct answer is evil twin because the attacker is impersonating a legitimate wireless network by using the same or a very similar SSID. Users connect because the name looks trusted, then the fake access point can capture credentials or redirect them to a malicious portal. On Security+, the combination of an unexpected connection and a fake login page is a strong indicator of an evil twin attack. Why others are wrong: Bluetooth pairing attacks involve Bluetooth devices, not Wi-Fi associations. NFC relay attacks use near-field communications and are unrelated to a wireless LAN sign-in page. MAC flooding is a switch attack and does not explain a fake SSID or captive portal. The scenario is specifically about a malicious Wi-Fi clone.
