A records room has repeated tailgating after hours and occasional door propping during deliveries. Management wants one control that prevents follow-on entry and another that immediately alerts security if the door is forced open or left ajar. Which two controls best meet the need? 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.
Best answer
Install a mantrap at the room entrance.
A mantrap allows only one person or credentialed entry at a time, which directly reduces tailgating.
Best answer
Add a door position sensor tied to an alarm or SIEM alert.
A sensor can alert security quickly if the door is forced open or remains open longer than allowed.
Distractor review
Place a larger warning sign on the wall beside the door.
Signs may deter some behavior, but they do not physically stop tailgating or create reliable alerts.
Distractor review
Mount a visible camera over the door only.
Cameras are useful for evidence, but they do not prevent entry and may not alert anyone in real time.
Distractor review
Replace the mechanical lock with the same type of lock and no monitoring.
A basic lock without monitoring does not address tailgating, door propping, or timely alerting.
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: Install a mantrap at the room entrance. — The best combination is a mantrap and a monitored door position sensor. The mantrap blocks follow-on entry by letting only one person enter at a time. The sensor provides immediate awareness if the door is forced open or held ajar, which is important when after-hours access must be tightly controlled. Together, they address both prevention and timely detection. Why others are wrong: Warning signs and cameras can help with deterrence or investigation, but they do not stop tailgating or guarantee immediate alerting. A plain lock without monitoring leaves the same operational gaps unchanged. Those controls are weaker than the required prevention-plus-alert combination.
