Employees in a lobby say their phones automatically connected to a wireless network named CorpWiFi, even though the legitimate access point was offline. They were then shown a fake sign-in page. What threat is this?
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
An evil twin access point impersonating the real corporate wireless network
An evil twin is a rogue access point that copies a trusted SSID to lure users into connecting.
Distractor review
A Bluetooth replay attack that reuses captured pairing data
Bluetooth replay attacks involve wireless protocol reuse, not a fake Wi-Fi access point and login page.
Distractor review
A cloud misconfiguration exposing a storage bucket to the internet
Cloud misconfiguration is a different issue and would not explain a bogus wireless network in the lobby.
Distractor review
A dependency compromise in a software library used by the company portal
Supply-chain compromise affects software packages, not a wireless network impersonation event.
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: An evil twin access point impersonating the real corporate wireless network — The correct answer is an evil twin access point. An evil twin copies the name of a trusted wireless network so nearby devices connect automatically or users choose it by mistake. Once connected, the attacker can capture traffic or present a fake portal to harvest credentials. The clue that the legitimate access point was offline, combined with the same network name and a fake sign-in page, strongly points to an evil twin. Why others are wrong: Bluetooth replay attacks do not involve a fake Wi-Fi SSID or captive portal. Cloud misconfiguration affects cloud services or data exposure, not local wireless impersonation. Dependency compromise is a software supply-chain problem and does not match the physical lobby wireless scenario.
