What is the main purpose of EVPN?
The correct answer is B. to provide scalable, interoperable multitenancy in data center and cloud networks. The main purpose of EVPN (Ethernet VPN) is to deliver scalable, interoperable, and efficient multitenant Layer 2 connectivity over an MPLS or IP network, especially for data center and cloud environments.

Why each option
The main purpose of EVPN (Ethernet VPN) is to deliver scalable, interoperable, and efficient multitenant Layer 2 connectivity over an MPLS or IP network, especially for data center and cloud environments.
EVPN operates as an overlay technology for Layer 2 VPN services, not as an underlay connectivity solution.
EVPN provides a highly scalable and interoperable solution for Layer 2 VPNs, enabling multitenancy in data center and cloud networks by using MP-BGP for MAC address learning and distribution, supporting features like multi-homing and active-active forwarding, which are crucial for modern data center interconnect.
While network infrastructure can contribute to IoT security, EVPN's primary function is not to provide advanced security features specifically for IoT devices.
EVPN provides Layer 2 connectivity; application-aware networking typically refers to higher-layer traffic classification and policy enforcement, which is not its main purpose.
