Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Password policy
Why it's wrong here
A password policy is an administrative control, enforced through configuration and user behaviour rather than barriers or guards. It would be the answer where the question asks for administrative controls; physical controls include locks, fences, bollards and security guards.
- ✗
Antivirus software
Why it's wrong here
Antivirus software is a technical (logical) control, operating within the endpoint's software layer rather than restricting physical access. It would be correct where the question asks for technical controls; physical controls include turnstiles, mantraps and CCTV cameras.
- ✓
Biometric door lock
Why this is correct
A biometric door lock restricts entry to a physical space by verifying a fingerprint or iris, so it operates on the tangible premises rather than on data, accounts or logical permissions. That places it squarely within physical security controls, unlike encryption or access lists.
- ✗
Firewall
Why it's wrong here
A firewall filters network traffic in software or hardware; it does not restrict physical access to premises or equipment. It is tempting because firewalls are foundational security controls, but they belong to the logical/technical category. A physical control would instead be something like locks, bollards, or security guards.
