What types of configurations are available for the AirPort Time Capsule?

The correct choice indicates that the AirPort Time Capsule is available in configurations of 2TB, 3TB, or it can be used as a model with no drive built-in. This flexibility allows users to select a capacity that best suits their storage needs. The 2TB and 3TB options provide adequate solutions for home users needing backup capabilities for multiple devices, while offering the no drive configuration suits scenarios where users might want to use their own external storage solutions, enhancing the overall versatility of the product.

In contrast, configurations limited to only 1TB and 2TB models do not reflect the broader options available, especially given that 3TB was a common offering. The notion of only having 3TB models misrepresents the product line-up, as it omits the 2TB option that was available. Lastly, stating that the AirPort Time Capsule is available exclusively in 4TB configurations disregards the reality of market offerings at the time, making it an inaccurate option.
