Which of the following capabilities is a feature of FTK?

The capability of recovering deleted files is indeed a feature of FTK (Forensic Toolkit). This tool is designed specifically for digital forensics and incorporates advanced data recovery techniques to retrieve deleted or lost data from various storage media. This includes the ability to scan drives for remnants of files that have been deleted but not yet overwritten, making it a powerful tool for forensic investigators.

FTK utilizes sophisticated algorithms to analyze file systems and reconstruct deleted files based on their structures and residual information present on the disk. This recovery capability is crucial for investigations where evidence may have been intentionally deleted, as it helps in uncovering crucial information that could be pivotal to a case.

In contrast, features such as creating virtual machines, analyzing network traffic, and performing live system analysis pertain to other software solutions or tools that specialize in those specific areas, but they do not fall under the primary functionalities provided by FTK. FTK's focus remains on in-depth forensic analysis, data recovery, and evidence management rather than virtualization, network analysis, or live analysis of operating systems.
