Question 71: A stakeholder questions the value of risk management & mitigation initiatives. Which response best demonstrates ROI?

Avoiding accountability discussions to prevent conflict
Distributing accountability so widely that no one is responsible
Building a culture of accountability with transparent reporting (Correct answer)
Centralizing accountability with a single individual

Correct answer: Building a culture of accountability with transparent reporting

Building a culture of accountability with transparent reporting is the correct approach because effective risk management & mitigation in the accessdata certified investigator field requires adherence to professional standards, evidence-based practices, and systematic methodology. This approach ensures consistent, high-quality outcomes while maintaining professional accountability.

Question 72: When using FTK Imager to acquire evidence, what does selecting the 'Verify images after they are created' option accomplish?

It encrypts the image for secure transport
It hashes the source and image to confirm the copy is bit-for-bit identical (Correct answer)
It scans the image for viruses
It automatically uploads the image to a cloud server

Correct answer: It hashes the source and image to confirm the copy is bit-for-bit identical

Post-acquisition verification hashes both the source drive and the resulting image to confirm forensic integrity and that no data was altered during imaging.
