Steven designing a computer forensics lab; how many exits should he include?

• A. Two
• B. One
• C. Three
• D. Four

Answer: (B)

Designing a computer forensics lab centers on tight access control and preserving the integrity and custody of evidence. Having a single exit ensures every person leaving the lab goes through one controlled, auditable point. You can log who exits, verify their identity, and record what items are being taken, which strengthens the chain of custody and reduces opportunities for tampering or unauthorized removal. Introducing additional exits creates more touchpoints where evidence could slip out or be mishandled and makes it harder to maintain a clear, verifiable trail. Of course, in real-world designs you must still meet safety and building-code requirements for emergency egress, but for the purpose of maintaining strict control over evidence and access, a single controlled exit is the most appropriate approach.
