Layer 2 Switchesoperate at theData Link Layer (Layer 2)and forward packets based onMAC addresses.

Layer 3 Switchesprovide bothLayer 2 switchingandLayer 3 routingcapabilities, allowingIP-based communication between VLANsviaVLANIF interfaces(VLAN Interfaces).

VLANIF interfaces act asvirtual interfacesassigned to VLANs, enablinginter-VLAN communicationwithout an external router.

Huawei WLAN solutions include multiplesecurity mechanismsto protect wireless networks from threats:

A (WIDS/WIPS air interface attack defense):Wireless Intrusion Detection/Prevention System (WIDS/WIPS) detects and mitigates rogue APs and other air interface threats.

C (WPA3 encryption):Latest Wi-Fi security standard providing stronger encryption and protection against brute-force attacks.

D (Authorization: Free mobility and unified authorization):Ensures that users maintain consistent access policies regardless of location, improving security and compliance.

In IP-based networks, routers use the destination IP address in the network layer header to determine the next hop for forwarding packets. The routing table contains entries that map destination IP addresses to outgoing interfaces or next-hop routers.

Source MAC and Destination MAC are Layer 2 (data link layer) addresses and are not used for routing decisions.

Source IP is irrelevant for routing, as the router focuses on delivering the packet to the destination IP address.

Thus, the correct answer is B , as routers use the destination IP address to make forwarding decisions.
