A forensics investigator needs to copy data around 42 GB to removable media for analysis at another location. Which type of media would be suitable?

Explanation:
Capacity is the key factor here. You need to copy about 42 GB of data, so the chosen media must hold at least that much. Blu-ray dual-layer discs provide around 50 GB of storage, which comfortably covers 42 GB and leaves room for overhead such as file system structures and checksums. The other options offer significantly less capacity: single-layer Blu-ray ≈25 GB, DVD-18 ≈17 GB, and HD-DVD ≈30 GB. Therefore, Blu-ray dual-layer is the suitable choice to carry the entire data set on one removable disc.
