CyberVista Test CyberVista Physical Security and Business Continuity Questions and Answers 1 — Questions and Answers
Question 1: What physical security control uses a small enclosed space with two sets of interlocking doors to prevent tailgating?
- Faraday cage
- Mantrap (airlock) (Correct answer)
- CCTV array
- Badge reader
Correct answer: Mantrap (airlock)
A mantrap requires an individual to authenticate before the second door opens, preventing unauthorized persons from following authorized users.
Question 2: Which environmental control is used to suppress fires in a data center without damaging electronic equipment?
- Water sprinkler system
- Clean agent fire suppression (e.g., FM-200) (Correct answer)
- CO2 flooding at high concentration
- Sand buckets
Correct answer: Clean agent fire suppression (e.g., FM-200)
Clean agent systems suppress fire using gas compounds that do not leave residue or damage sensitive electronics, unlike water-based suppression.
Question 3: What is the purpose of a Faraday cage in physical security?
- To prevent unauthorized physical entry to a server room
- To block electromagnetic signals from entering or leaving a shielded space (Correct answer)
- To detect motion in restricted areas
- To provide redundant power to critical systems
Correct answer: To block electromagnetic signals from entering or leaving a shielded space
A Faraday cage is a mesh of conductive material that attenuates external electromagnetic fields, preventing wireless eavesdropping or EMI.
Question 4: Which of the following best defines a Recovery Time Objective (RTO)?
- The maximum tolerable amount of data loss measured in time
- The maximum acceptable time to restore a system or process after a disruption (Correct answer)
- The minimum number of backup copies required
- The time interval between scheduled backups
Correct answer: The maximum acceptable time to restore a system or process after a disruption
RTO defines how quickly a system must be restored after an incident to avoid unacceptable business impact.
Question 5: What does Recovery Point Objective (RPO) measure?
- The speed at which failover to a backup site occurs
- The maximum amount of data loss an organization can tolerate, expressed as a time interval (Correct answer)
- The number of redundant systems required
- The cost to recover from a disaster
Correct answer: The maximum amount of data loss an organization can tolerate, expressed as a time interval
RPO defines the oldest data that is acceptable to restore to; a 1-hour RPO means you may lose up to one hour of transactions.
Question 6: Which type of backup site is fully equipped and operational, allowing near-immediate failover during a disaster?
- Cold site
- Warm site
- Hot site (Correct answer)
- Mobile site
Correct answer: Hot site
A hot site is a fully mirrored, always-on facility that can take over operations within minutes of a primary site failure.
