Question

RPL supports: 1.Message confidentiality 2. Loop detection in the routes 3. Data path validation 4. All of these

Answer 1

all of these................................................

Answer 2

The answer is 4. All of these

Explanation:

RPL "Routing Protocol for Low-Power and Lossy Networks" is a protocol for routing wireless networks which works with low power consumption and generally vulnerable to packet loss.

This protocol can immediately create network routes by share routing knowledge and make adaptable with the topology in a valuable way. The RPL fully supports the confidentiality and integrity of the messages routed.

The "low-power and lossy" network behavior drives RPL's make use of the "on-demand loop" detection method using data packets.
