Full question →mediummultiple choiceObjective-mapped
Several employees in a branch office report that their laptops automatically connected to a network named "CorpWiFi" even though they were away from the office. Shortly afterward, a few users saw a captive portal asking them to re-enter company credentials. Which threat best explains this situation?
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
Best answer
Evil twin access point impersonating the legitimate wireless network
An evil twin is a rogue access point configured to look like the trusted wireless network, often using the same or a very similar SSID. Because clients may auto-connect, attackers can capture credentials or inspect traffic through the fake network. The captive portal and automatic connection away from the office strongly suggest a malicious wireless impersonation setup.
B
Distractor review
Bluetooth pairing abuse from a nearby device
Bluetooth abuse is possible in some environments, but it would not explain laptops joining a Wi-Fi network with a familiar SSID.
C
Distractor review
DNS poisoning caused by a compromised resolver
DNS poisoning can redirect users to malicious destinations, but it does not create a fake wireless access point that devices join automatically.
D
Distractor review
NFC relay attack against the laptops' login process
NFC relay attacks involve short-range communication and are not the likely cause of automatic Wi-Fi association and captive portal prompts.
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 access point impersonating the legitimate wireless network — The correct answer is evil twin access point. The key indicators are that users automatically connected to a network with the same name as the legitimate wireless network and were then presented with a credential-harvesting portal. Evil twin attacks rely on a rogue AP imitating a trusted SSID to lure devices into connecting, especially if users have previously saved the network profile. This can expose credentials and session data. Why others are wrong: Bluetooth and NFC attacks are short-range device attacks, but they do not match automatic Wi-Fi association. DNS poisoning can redirect traffic after name resolution, yet it does not explain the fake access point behavior. The evidence specifically points to wireless impersonation, not a resolver compromise or proximity-based radio attack.
