Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
A caller says they are from IT support and asks a user to read back the one-time MFA code that just arrived on their phone. What type of attack is this 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
Phishing
Phishing usually uses email or a fake website. This scenario is a live phone call, so the channel is different.
B
Distractor review
Smishing
Smishing uses SMS text messages to trick users. The attacker here is calling the user directly, not sending a text message.
C
Best answer
Vishing
Vishing is voice phishing, where an attacker uses a phone call or VoIP call to manipulate a target. Asking for an MFA code by phone is a common and dangerous tactic because the attacker may be trying to complete a real login.
D
Distractor review
Baiting
Baiting relies on lures such as free media, gifts, or infected USB drives. The scenario is a deceptive phone call, not a physical lure.
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: Vishing — The best answer is vishing because the attacker is using a voice call to pressure the user into revealing an MFA code. This is a classic help desk or IT impersonation tactic. The presence of a live conversation is the key clue. Even though the attacker is also impersonating IT support, the attack is specifically delivered by voice, which makes vishing the most accurate choice. Why others are wrong: Phishing is typically email-based, not a phone call. Smishing is delivered through text messages. Baiting involves physical or digital lures, such as a USB drive or free download, and does not match this scenario. The call itself is the strongest indicator that this is vishing.
