220-1102 Practice Question: A help desk technician receives a call from a…
This 220-1102 practice question tests your understanding of a help desk technician receives a call from a…. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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 call from a user who received an email with an attachment labeled 'Invoice_2024.exe'. The user opened the attachment, but nothing appeared to happen. The email appeared to come from a known vendor, but the sender's email address contains misspellings. Which of the following BEST describes this type of attack, and what should the technician advise the user to do NEXT?
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
Spear phishing – advise the user to delete the email and ignore it
Spear phishing is targeted, but the description (generic invoice, misspelled address) indicates a broader phishing attempt. Deleting the email is insufficient because the user already opened the attacker, so the system may be compromised.
B
Best answer
Phishing – advise the user to report the incident to the security team
This is a phishing attack involving a malicious attachment. The user should immediately report it so the security team can investigate and remediate any potential infection.
C
Distractor review
Vishing – advise the user to ignore the message since it is not a phone call
Vishing is voice phishing (phone calls). This attack arrived via email and used an executable attachment, so it is not vishing.
D
Distractor review
Pretexting – advise the user to forward the email to IT for verification
Pretexting involves creating a fabricated scenario to steal information, but the attack here relies on a malicious attachment, not on building a false pretext. Forwarding to IT may be part of reporting, but the best immediate action is to report to the security team, not just forward.

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.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

FAQ
Questions learners often ask
What does this 220-1102 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Phishing – advise the user to report the incident to the security team — The email is a phishing attempt, specifically using a malicious executable attachment. The user should report the incident to the security team so they can take appropriate action, such as scanning the workstation and blocking the sender. Simply deleting the email or ignoring it does not address the potential compromise. This is not vishing (voice), not pretexting (fabricated scenario), and not spear phishing (targeted) because the attack is generic (though it could be considered spear phishing if the vendor was specifically spoofed; however, the question emphasizes the attachment and generic phishing nature, so phishing is the broader correct category).
What should I do if I get this 220-1102 question wrong?
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related 220-1102 NAT questions on configuration and troubleshooting.
