Which of the following is NOT a requirement when preparing for a digital examination?

Leaving power management features enabled is not a requirement when preparing for a digital examination. When conducting a forensic examination, it is crucial to maintain the integrity and stability of the environment. Keeping power management features such as sleep or hibernate mode enabled can interrupt the examination process, potentially leading to data loss or corruption. This is because, if a machine enters a power-saving state, it may disrupt ongoing processes or data retrieval activities.

In contrast, turning off unnecessary services, ensuring that the system clock does not synchronize (to preserve timestamps accurately), and disabling all screen savers are common best practices in digital forensics to ensure that evidence remains intact and the examination can proceed without interruptions. These actions help prevent interference from background processes and maintain a controlled environment for the analysis.
