What is a requirement when using the EnCase Portable Boot CD?

When using the EnCase Portable Boot CD, one of the essential requirements is that the license dongle must be connected for access. The EnCase software typically requires licensing to ensure that users are authorized to conduct forensic examinations. The dongle serves as a hardware key that verifies the legitimacy of the software usage. Without the dongle, the software may not function properly or may restrict access to certain features necessary for conducting thorough forensic investigations.

The other choices, while they may seem plausible, do not accurately capture the critical requirements for using the EnCase Portable Boot CD. For instance, while compatibility with the system hardware is important for general functionality, there isn't a specific requirement regarding the hard drive type just for the use of the Portable Boot CD. Similarly, booting in safe mode is not a necessity for the EnCase boot process, and while using external devices like USB drives can enhance functionality in some cases, having a USB drive present is not a categorical requirement for utilizing the Boot CD effectively.
