220-1102 Physical Security Controls — 10 Questions

Question 1

A customer reports that their laptop was stolen from their desk over the weekend. The laptop contained sensitive client data. Which physical security control should have been implemented to prevent this theft?

Accepted Answer

Cable lock. Cable locks are a simple and effective physical security control to prevent laptop theft by securing the device to a desk or fixed object. This scenario tests the understanding of basic physical deterrents against opportunistic theft in an office environment.

Answer

Biometric authentication

Answer

Full disk encryption

Answer

Smart card reader

Question 2

During a security audit, you find that a company's server room door is propped open with a trash can to allow airflow. What is the most immediate physical security risk in this scenario?

Accepted Answer

Unauthorized personnel can enter the server room. Propping open a secured door completely bypasses the access control system, allowing unauthorized individuals to enter the server room undetected. This highlights the importance of maintaining door closure mechanisms to ensure physical security.

Answer

Increased dust entering the server room

Answer

Fire suppression system may not work

Answer

The door closer will wear out faster

Question 3

A company's server room has a door with a proximity card reader. Employees report that the door sometimes does not close fully, allowing it to be pushed open without a card. What is the best solution?

Accepted Answer

Install a door closer mechanism. A door closer ensures the door automatically shuts and latches after each use, preventing it from being left ajar. This addresses the root cause of the security gap by maintaining the integrity of the access control system.

Answer

Replace the proximity card reader with a biometric reader

Answer

Add a security camera to monitor the door

Answer

Increase the frequency of badge audits

Question 4

A company is designing a secure entry for a high-security lab. They need to ensure that only one person can enter at a time and that the person must be authenticated before the second door opens. Which physical security control should be used?

Accepted Answer

Mantrap with smart card and biometric authentication. A mantrap with two interlocking doors and authentication requirements ensures one-person-at-a-time entry, preventing tailgating and piggybacking. This is the gold standard for high-security areas requiring strict access control.

Answer

Turnstile with biometric reader

Answer

Security guard with logbook

Answer

Cipher lock with door alarm

Question 5

A technician is configuring a new server rack in a shared office space. Which physical security measure should be applied to prevent unauthorized physical access to the servers?

Accepted Answer

Use rack-mount locks on each server chassis. Rack-mount locks secure the server chassis within the rack, preventing unauthorized removal or tampering with individual servers. This is a standard physical control for multi-tenant or shared spaces where racks are accessible.

Answer

Install a door alarm on the office entrance

Answer

Enable BitLocker on all server drives

Answer

Configure a strong BIOS password

Question 6

A technician is troubleshooting why a smart card reader at a secure entrance fails intermittently. Users can sometimes enter, but other times the reader does not respond. What should the technician check first?

Accepted Answer

Check the cabling and connections to the reader. Loose or damaged cabling is a common cause of intermittent failures in physical access control systems. Checking the physical connection is a logical first step before moving to software or configuration issues.

Answer

Update the smart card reader firmware

Answer

Replace the smart cards for all users

Answer

Reconfigure the access control software

Question 7

A small office wants to restrict access to the server room to only authorized IT staff. They need a solution that does not require keys or cards that can be lost. Which physical security control should they implement?

Accepted Answer

Biometric lock. Biometric locks use unique physical characteristics like fingerprints, eliminating the need for keys or cards that can be lost or stolen. This question tests knowledge of access control methods that combine security with convenience.

Answer

Keyed lock

Answer

Proximity card reader

Answer

Cipher lock

Question 8

A company is implementing a new policy to prevent tailgating at the main entrance. Which physical security control should they deploy?

Accepted Answer

Mantrap. A mantrap uses two interlocking doors to ensure only one person can enter at a time, effectively preventing tailgating. This tests understanding of specialized access controls designed to enforce one-person-per-authentication.

Answer

Security cameras

Answer

Biometric reader

Answer

Badge reader

Question 9

A data center manager wants to implement a physical security control that can detect if a server chassis has been opened without authorization. Which control should they use?

Accepted Answer

Tamper-evident seals. Tamper-evident seals show visible signs of removal or tampering, indicating unauthorized access to the server chassis. This is a passive but effective control for detecting physical breaches after they occur.

Answer

Intrusion detection system (IDS) on the network

Answer

Chassis intrusion switch

Answer

Video surveillance

Question 10

A school district is deploying laptops to students and wants to deter theft while keeping devices usable. Which physical security control should they implement on the laptops?

Accepted Answer

Apply asset tracking tags. Asset tracking tags allow the school to identify and recover stolen devices, acting as a deterrent and aiding in recovery. This balances security with usability, as the laptops remain fully functional for students.

Answer

Install a cable lock on each laptop

Answer

Use a laptop safe

Answer

Enable a BIOS password
