Question 1,057 of 1,152
Threats, Vulnerabilities, and MitigationshardMultiple ChoiceObjective-mapped

Quick Answer

The safest first action is to end the call and verify the request through a published help desk number or ticketing system. This is correct because the caller’s knowledge of internal details like the org chart and supervisor’s name, combined with the demand to use a callback number from a text message, are textbook social engineering red flags designed to bypass MFA security. On the Security+ SY0-701 exam, this scenario tests your ability to recognize vishing and callback phishing attacks, where attackers spoof caller ID and use urgency to trick help desk staff into resetting MFA tokens. A common trap is assuming that knowing internal names proves legitimacy, but attackers harvest this data from LinkedIn or data breaches. Remember the memory tip: “Hang up, look up”—always independently verify through official channels, never trust an unsolicited callback number.

SY0-701 Threats, Vulnerabilities, and Mitigations Practice Question

This SY0-701 practice question tests your understanding of threats, vulnerabilities, and mitigations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: out-of-band verification uses a separate, trusted communication channel.. 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 call from someone claiming to be a new contractor whose MFA app failed during travel. The caller knows the company org chart, names the technician's supervisor, and says the technician should use a callback number included in a text message they just sent. What is the safest first action?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

End the call and verify the request through a published help desk number or ticketing system.

Option C is correct because the safest first action when receiving an unsolicited call requesting privileged actions (like MFA reset) is to independently verify the request through official channels. The caller's knowledge of internal details (org chart, supervisor name) and the request to use a callback number from a text message are classic social engineering red flags, as the callback number could be attacker-controlled. Hanging up and calling back via a published help desk number ensures the request is legitimate and prevents MFA bypass or account takeover.

Key principle: Out-of-band verification uses a separate, trusted communication channel.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Reset MFA immediately, since the caller has provided enough internal details to seem credible.

    Why it's wrong here

    Internal details can be stolen or guessed. Credibility in a call is not proof of identity, so resetting MFA immediately would be unsafe.

  • Ask the caller to read a one-time code aloud so the technician can confirm their identity.

    Why it's wrong here

    One-time codes are authentication secrets. Asking for them would help the attacker complete account takeover rather than verify identity.

  • End the call and verify the request through a published help desk number or ticketing system.

    Why this is correct

    The safest first action is to stop using information supplied by the caller and verify through a trusted, independently obtained contact path. Because the attacker already knows internal details and provided a callback number in a text, those channels cannot be trusted. Using a published help desk number or the official ticketing system preserves least risk and prevents social engineering from extending into account reset abuse.

    Clue confirmation

    The clue word "first" in the question point toward this answer.

    Related concept

    Out-of-band verification uses a separate, trusted communication channel.

  • Approve the request if the caller can name the supervisor and the contractor's project team.

    Why it's wrong here

    Knowing names and project details is not strong identity proof. Pretext attackers often gather that information from public sources or prior breaches.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may assume the caller's knowledge of internal details (supervisor name, org chart) is sufficient proof of identity, but CompTIA tests the principle that any unsolicited request for privileged actions must be independently verified through a trusted channel, not through information the caller provides.

Detailed technical explanation

How to think about this question

Social engineering attacks often exploit the 'authority' and 'liking' principles by using internal knowledge to build trust. In this scenario, the callback number in the text message could be a VoIP number controlled by the attacker, enabling a man-in-the-middle attack if the technician calls it. The correct verification process involves using a pre-established, out-of-band communication channel (e.g., calling the help desk's published number or checking the ticketing system) to ensure the request is genuine, aligning with NIST SP 800-63B identity assurance guidelines.

KKey Concepts to Remember

  • Out-of-band verification uses a separate, trusted communication channel.
  • Social engineering pretexts often include seemingly credible internal details.
  • Never trust contact information provided by an unverified caller.
  • MFA resets require stringent identity verification to prevent account takeover.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Out-of-band verification uses a separate, trusted communication channel.

Real-world example

How this comes up in practice

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.

Same concept, more angles

2 more ways this is tested on SY0-701

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. A help desk technician receives a phone call from someone claiming to be the VP of Finance. The caller says they are in an airport, forgot their phone, and need a password reset immediately. They also ask the technician to skip callback verification because a meeting starts in five minutes. Which two details are the strongest indicators of a pretexting or vishing attempt? Select two.

medium
  • A.the caller claims an executive title and uses authority to pressure the technician
  • B.the call is routed through the company ticketing system with an approved change record
  • C.the caller asks the technician to bypass identity verification and callback procedures
  • D.the caller answers all security questions correctly after being prompted for them
  • E.the call occurs after normal business hours on a holiday weekend

Why A: Option A is correct because the caller's use of an executive title (VP of Finance) and urgent authority pressure is a classic social engineering tactic known as pretexting. In a vishing (voice phishing) attack, the attacker fabricates a scenario to manipulate the technician into bypassing standard security procedures. This aligns with the SY0-701 domain on threats, vulnerabilities, and mitigations, specifically social engineering techniques.

Variation 2. A help desk technician receives a phone call from someone who claims to be the CFO. The caller knows the executive team structure, says they are traveling, and insists the technician reset MFA to 'avoid delaying a wire transfer.' Which social engineering technique is the caller primarily using?

medium
  • A.Pretexting, because the caller builds a believable story to manipulate the employee
  • B.Baiting, because the caller is offering something valuable in exchange for action
  • C.Vishing, because the attack happens by voice call
  • D.Smishing, because the attacker is using a mobile device

Why A: The caller is using pretexting because they have fabricated a scenario (the CFO traveling and needing an urgent wire transfer) and assumed a false identity to manipulate the help desk technician into resetting MFA. Pretexting relies on a crafted story or pretext to gain trust and bypass security controls, which is exactly what the caller is doing here.
