Which of the following data acquisition methods did Tyler perform in the scenario of investigating a crime scene and inspecting a specific portion of the drive?

In the context of investigating a crime scene and focusing on a specific portion of the drive, sparse acquisition is the method that appropriately aligns with Tyler's actions. Sparse acquisition involves selectively capturing only the relevant sections of data, rather than copying the entire drive. This can be especially useful in scenarios where the investigator is looking for particular files or data fragments that are pertinent to the case, as it allows for efficient use of resources and time.

Sparse acquisition can help to minimize the amount of data processed while still obtaining necessary evidence, which is crucial in legal contexts. This method can also assist in maintaining data integrity and chain of custody, as it limits exposure to unnecessary data that does not pertain to the investigation.

In contrast, the other methods listed, such as bit-stream imaging and bit-stream disk-to-disk, involve creating complete copies of the entire drive. These approaches can be more comprehensive but would not specifically cater to the need for focused analysis on a particular drive segment.
