Which two foundational aspects of IoT are still evolving and being worked on by the...

The IoT ecosystem continues to evolve around industry-wide agreements on protocols, frameworks, security, interoperability, and standards:

D: Multiple IoT consortia (such as Industrial Internet Consortium, Open Connectivity Foundation, etc.) are still developing open frameworks and interoperability models.

E: IoT standards for security, data privacy, management, and protocol interoperability are still maturing as the market rapidly evolves.

Why other options are incorrect:

A: Wi-Fi protocols (such as 802.11ax) are already mature and standardized for IoT.

B: Regulatory domains (frequency allocations, power levels) are already well-established.

C: Low-energy Bluetooth sensors are already standardized and widely implemented.
