This SY0-701 practice question tests your understanding of threats, vulnerabilities, and mitigations. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A help desk technician receives a phone call from someone claiming to be a contractor. The caller says their MFA app was lost, asks the technician to enroll a new device immediately, and pressures them to ignore policy. What type of attack is this?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "immediately / without restart"
Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
Phishing
Why wrong: Phishing usually arrives by email or a fake website, not through a live phone call.
Vishing
Vishing uses voice calls to pressure a target into revealing information or changing security settings.
Smishing
Why wrong: Smishing uses text messages, so this does not match a voice-based contact attempt.
Baiting
Why wrong: Baiting relies on a tempting lure, such as free media or a found device, not a phone conversation.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Vishing
This is a vishing (voice phishing) attack because the attacker uses a phone call to impersonate a contractor and socially engineer the technician into bypassing MFA enrollment policies. Vishing specifically exploits voice communication to manipulate victims, unlike phishing which uses email or malicious links.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Phishing
Why it's wrong here
Phishing usually arrives by email or a fake website, not through a live phone call.
Vishing
Why this is correct
Vishing uses voice calls to pressure a target into revealing information or changing security settings.
Clue confirmation
The clue word "immediately / without restart" in the question point toward this answer.

Smishing
Why it's wrong here
Smishing uses text messages, so this does not match a voice-based contact attempt.
Baiting
Why it's wrong here
Baiting relies on a tempting lure, such as free media or a found device, not a phone conversation.
Common exam traps
The trap here is confusing vishing with phishing because both involve social engineering, but the key differentiator is the communication medium—voice (phone call) vs. electronic message (email/SMS).
Detailed technical explanation
Vishing often leverages caller ID spoofing to appear as a legitimate internal number or vendor, bypassing initial suspicion. Attackers may also use voice deepfakes or pre-recorded audio to mimic known contacts, making detection harder without strict call-back verification procedures. Real-world vishing campaigns frequently target help desks to reset credentials or bypass MFA, as seen in recent MFA fatigue attacks.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
An employee at a financial services firm receives an email that appears to come from the IT helpdesk, asking them to reset their password via a link. The link leads to a convincing fake portal that harvests credentials. Security teams use phishing simulations and security-awareness training to reduce this attack vector. Questions like this test whether you can identify social engineering techniques and appropriate controls.
