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

Vishing, because the attacker is using a voice call to manipulate the target in real time.

Vishing is voice-based phishing. The attacker used a phone call, gained trust with specific details, and pressured the employee to reveal an MFA code. That real-time conversation and the request for a secret value are classic indicators of a voice social engineering attempt.

B

Distractor review

Smishing, because the attacker requested a code and mentioned a financial problem.

Smishing happens through text messages or SMS, not through a live phone conversation.

C

Distractor review

Baiting, because the caller offered to fix the payment issue for the employee.

Baiting relies on a lure, such as free media or an enticing download. A fraudulent support call is better described as vishing and impersonation.

D

Distractor review

Tailgating, because the attacker used a trusted identity to gain access.

Tailgating refers to physical entry by following someone through a secured area. This incident occurred over the phone, not at a door or badge-controlled entrance.

Common exam trap

Common exam trap: OSPF can fail even when IP connectivity looks correct

OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.

Technical deep dive

How to think about this question

OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.

KKey Concepts to Remember

  • OSPF neighbours must agree on key parameters.
  • Router ID selection can affect neighbour relationships and LSDB output.
  • OSPF cost influences the preferred path.
  • A route can appear in OSPF information but not become the installed route.

TExam Day Tips

  • Check area mismatch first when OSPF adjacency fails.
  • Review passive interfaces when a network is advertised but no neighbour forms.
  • Use show ip ospf neighbor and show ip route clues carefully.

FAQ

Questions learners often ask

What does this SY0-701 question test?

OSPF neighbours must agree on key parameters.

What is the correct answer to this question?

The correct answer is: Vishing, because the attacker is using a voice call to manipulate the target in real time. — Vishing is the correct classification because the attacker used a live voice call to impersonate a trusted organization and pressure the victim into revealing a one-time MFA code. The request for an MFA code is especially dangerous because it can defeat account protections in real time. Even when caller ID or context seems legitimate, employees should never share authentication secrets over an unsolicited call. Why others are wrong: Smishing is text-based, not voice-based. Baiting uses a lure rather than a fraudulent support call. Tailgating is a physical access tactic involving someone entering a restricted area behind another person, so it does not fit a phone-based fraud attempt.
