Full question →mediummultiple choiceObjective-mapped
Network engineers need to administer internal switches from home. The company wants encrypted management traffic, strong user verification, and no management ports exposed directly to the internet. Which approach is best?
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
Require a VPN or ZTNA connection with MFA, then allow SSH or HTTPS management only through that protected tunnel.
A protected remote-access layer keeps management services off the public internet while preserving encryption and strong authentication.
B
Distractor review
Expose SSH on the internet and rely on key-based authentication alone.
Public exposure increases attack surface, and key authentication alone does not eliminate brute-force or scanning risk.
C
Distractor review
Use RDP with port forwarding because it is simpler for remote support.
Port forwarding exposes a management service to the internet and is not the safest architecture for network devices.
D
Distractor review
Allow split tunneling without MFA so engineers can reduce latency while working remotely.
Split tunneling without MFA weakens assurance and can bypass the security boundary for sensitive administrative traffic.
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.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Require a VPN or ZTNA connection with MFA, then allow SSH or HTTPS management only through that protected tunnel. — The best approach is to place the management access behind a VPN or zero-trust access layer with MFA, then allow SSH or HTTPS only through that tunnel. This keeps administrative services off the public internet, reduces exposure to scanning and brute-force attacks, and still supports encrypted, authenticated remote management. It is a strong architectural choice for secure administration from untrusted locations. Why others are wrong: Publishing SSH directly to the internet creates unnecessary exposure, even with key authentication. RDP with port forwarding is similarly risky because it opens a management path to external scanning and attack. Split tunneling without MFA weakens the access boundary and is not appropriate for sensitive device administration. The goal is secure remote management with minimal public exposure, which the tunnel-based design provides.
