The answer is restricted access with visitor logs and biometric authentication. These controls are essential requirements for a computer forensics lab because they enforce strict chain of custody and prevent unauthorized tampering with evidence, which is the foundation of any defensible forensic investigation. Without documented visitor logs and biometric verification, the integrity of digital evidence can be legally challenged, as there is no proof of who accessed the lab or when. On the Computer Hacking Forensic Investigator CHFI exam, this concept tests your understanding of physical security controls as part of the lab’s operational best practices, often appearing alongside questions about environmental controls like UPS and surge protectors. A common trap is confusing logical access controls, such as passwords, with physical ones—biometrics are physical, not logical. Remember the mnemonic “Locks and Logs” to recall that both physical barriers and audit trails are non-negotiable for a compliant forensic lab.
CHFI Computer Forensics Lab Practice Question
This CHFI practice question tests your understanding of computer forensics lab. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following are essential requirements for a computer forensics lab according to best practices?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Uninterruptible power supply (UPS) and surge protectors
A is correct because a UPS provides temporary power during outages to prevent data loss or corruption during forensic imaging, while surge protectors guard against voltage spikes that could damage sensitive lab equipment. Best practices require both to ensure chain of custody integrity and hardware reliability.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Uninterruptible power supply (UPS) and surge protectors
Why this is correct
Clean power is critical to protect forensic equipment and prevent data loss.
Clue confirmation
The clue word "best" in the question point toward this answer.

✗
Offsite cloud storage for all case files
Why it's wrong here
Cloud storage without proper encryption and compliance may breach confidentiality.
✗
Shared workstations to reduce hardware costs
Why it's wrong here
Shared workstations can lead to cross-contamination of evidence.
✓
Restricted access with visitor logs and biometric authentication
Why this is correct
Access control ensures only authorized individuals handle evidence.
Clue confirmation
The clue word "best" in the question point toward this answer.

✗
Open wireless network for flexibility
Why it's wrong here
Open wireless networks are insecure; wired networks are recommended.
Common exam traps
Common exam trap: answer the scenario, not the keyword
EC-Council often tests the misconception that cloud storage is acceptable for forensic labs, but candidates must remember that chain of custody and jurisdictional control require local, encrypted storage with strict access logging.
Detailed technical explanation
How to think about this question
A UPS with automatic voltage regulation (AVR) and sufficient runtime (e.g., 15-30 minutes) allows forensic examiners to safely shut down systems and preserve evidence during power events. Surge protectors should meet UL 1449 standards with a clamping voltage below 400V to protect against transient surges. In practice, labs often use enterprise-grade UPS units with network monitoring to log power events, which can be critical for proving evidence integrity.
KKey Concepts to Remember

Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CHFI exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

Variation 1. Which TWO of the following are essential components of a computer forensics lab according to CHFI best practices?
hard
A.Server farm for data processing
✓ B.Evidence storage area with controlled access
C.Public-facing website for case management
D.Coffee machine for staff convenience
✓ E.Forensic workstation with specialized software
Why B: Option B is correct because a computer forensics lab must have a secure evidence storage area with controlled access to maintain the chain of custody and prevent tampering or unauthorized access to digital evidence. CHFI best practices emphasize physical security controls, such as biometric locks or access logs, to ensure evidence integrity throughout the investigation lifecycle.
