Answer is Wrong!
Answer is Right!
The correct answer is: A. ietf 6lowpan
6LoWPAN (IPv6 over Low-Power Wireless Personal Area Networks) is a networking protocol that enables IPv6 to be used on low-power, low-bandwidth networks such as IEEE 802.15.4. It does this by reducing the size of IPv6 packets and headers, and by using a different addressing scheme.
6LoWPAN is an important technology for the Internet of Things (IoT), as it allows IoT devices to communicate with each other and with the Internet. It is also used in other applications such as smart metering and asset tracking.
The other options are incorrect because:
- CoAP (Constrained Application Protocol) is a lightweight application protocol for constrained devices. It is designed to be used over low-power, low-bandwidth networks such as 6LoWPAN.
- RFID (Radio Frequency Identification) and NFC (Near Field Communication) are technologies for identifying objects using radio waves. They are not used for networking.
- IEEE 802.15.4 is a standard for low-power, low-bandwidth wireless networks. It is the underlying technology for 6LoWPAN.
