A user receives an SMS from 'IT Service Desk' saying their MFA enrollment expires today and includes a shortened link. Five minutes later, the user gets a phone call from the same number asking them to read back the code shown in the authenticator app so the ticket can be closed. Which two attack channels are used in this campaign? Select two.
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.
Distractor review
Email phishing is used because the attacker is requesting a login action.
Phishing is a broad term, but this scenario is specifically about SMS and voice, not email. Since the channel is not email, calling it email phishing would be inaccurate. The attacker may still be phishing generally, but the more precise attack channels are different and more useful for response.
Best answer
Smishing is used because the first lure arrives by text message.
Smishing is phishing delivered through SMS or another text-based mobile messaging channel. The fake IT Service Desk text with a shortened link is a classic example because it attempts to get the user to click a link and interact outside the normal support process.
Best answer
Vishing is used because the follow-up request occurs by phone call.
Vishing uses voice calls to pressure or trick a victim, often by impersonating support staff or an executive. Asking the user to read back an MFA code on the phone is a strong indicator of vishing because it tries to defeat authentication through social manipulation rather than technical compromise.
Distractor review
Baiting is used because the attacker offers a free reward or device.
Baiting usually involves enticing the victim with something attractive, such as free media, hardware, or a promised benefit. This scenario instead uses a fake service request and a follow-up call. There is no lure of a reward, so baiting is not the best fit.
Distractor review
Tailgating is used because the attacker follows someone into a restricted area.
Tailgating is a physical social engineering tactic involving unauthorized entry into a secured space. This scenario takes place over SMS and phone, so it does not involve a person following another through a door or into a controlled area. That makes tailgating irrelevant here.
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: Smishing is used because the first lure arrives by text message. — The campaign uses two delivery channels. The text message is smishing because it arrives through SMS and includes a link designed to pull the victim into a fake support flow. The follow-up call is vishing because the attacker uses a voice conversation to pressure the user into disclosing an MFA code. Together, those channels show a coordinated social engineering attack across mobile messaging and telephony. Why others are wrong: Email phishing, baiting, and tailgating do not match the evidence. The attack is not email-based, it does not offer a reward or device, and it does not involve physical access at all. The key distinction is channel: SMS first, then voice. That makes smishing and vishing the precise answers.
