Full question →mediummultiple choiceObjective-mapped
After a facilities outage, multiple employees report that their phones automatically joined a network named "CorpWiFi" in the lobby even though the legitimate access point was offline. A nearby attacker device then captured the captive portal login traffic. 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
Rogue access point
A rogue access point is unauthorized, but the key clue here is that it imitates the legitimate corporate SSID.
B
Best answer
Evil twin
An evil twin mimics a trusted wireless network name and often a stronger signal to lure devices into connecting to it.
C
Distractor review
Bluetooth bluejacking
Bluejacking sends unsolicited Bluetooth messages; it does not involve a fake Wi-Fi access point or captive portal capture.
D
Distractor review
NFC relay attack
An NFC relay attack extends short-range contactless communication, which does not fit the wireless association and portal login symptoms.
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 — This is most likely an evil twin attack. The attacker created a wireless access point that impersonated the corporate SSID, causing nearby devices to connect automatically because the name looked familiar and the legitimate access point was unavailable. Once the users connected, the attacker could intercept portal credentials or redirect traffic. The strongest clue is the combination of a cloned network name, automatic connection, and credential capture. Why others are wrong: A rogue access point is simply unauthorized wireless equipment, but it does not necessarily impersonate a trusted SSID. Bluejacking is a Bluetooth messaging nuisance, not a Wi-Fi impersonation technique. An NFC relay attack uses contactless proximity hardware and is unrelated to phones joining a fake corporate wireless network.
