Which technique does NOT enhance data portability in cloud operations?

Data portability in cloud operations refers to the ability to transfer data easily between different cloud services or back to on-premises storage without significant barriers. Techniques to enhance data portability focus on ensuring that data can be accessed, moved, and utilized across various platforms and providers.

Using DRM (Digital Rights Management) and DLP (Data Loss Prevention) solutions typically introduces restrictions and controls over data usage and access to protect sensitive information. While these measures are important for security and compliance, they can hinder the ease of transferring data between systems. Instead of facilitating data movement, DRM and DLP can create complexities that might restrict how data can be utilized or moved, ultimately affecting data portability.

In contrast, avoiding proprietary data formats fosters data portability by ensuring that data can be easily accessed and understood across different systems without needing specific software tied to a particular vendor. Ensuring favorable contract terms can provide the flexibility necessary for transferring data without penalties or restrictions. Likewise, eliminating physical limitations to moving data (such as bandwidth restrictions or geographical constraints) further supports data mobility.

Therefore, the technique that does not enhance data portability is the use of DRM and DLP solutions, as these are primarily aimed at protecting data rather than facilitating its movement.
