220-1102 Practice Question: Implement multi-factor authentication (MFA) for…
This 220-1102 practice question tests your understanding of implement multi-factor authentication (mfa) for…. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 company wants to implement multi-factor authentication (MFA) for remote access to its VPN. Which of the following combinations represents a valid MFA setup?
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
Password and security question
Both are 'something you know' factors, which only provides single-factor authentication.
B
Best answer
Smart card and PIN
The smart card is 'something you have' and the PIN is 'something you know,' making it a valid two-factor authentication method.
C
Distractor review
Fingerprint and retina scan
Both are biometric (something you are) factors, so this is still single-factor authentication.
D
Distractor review
Password and username
Both are typically knowledge factors. A username alone is not a secret, and this combination still counts as single-factor.
Answer analysis
Why the other options are wrong
Understanding why incorrect options are tempting is as important as knowing the correct answer.
- ✗
Password and security question
Both are 'something you know' factors, which only provides single-factor authentication.
- ✗
Fingerprint and retina scan
Both are biometric (something you are) factors, so this is still single-factor authentication.
- ✗
Password and username
Both are typically knowledge factors. A username alone is not a secret, and this combination still counts as single-factor.
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: Smart card and PIN — Multi-factor authentication requires combining at least two different factors: something you know (password, PIN), something you have (smart card, token), or something you are (biometric). A smart card (something you have) plus a PIN (something you know) meets this requirement. A password plus a security question are both knowledge factors. Fingerprint plus retina scan are both biometric factors. Password plus username are both knowledge-based and not MFA.
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.
