Which three statements describe features of Cisco devices that perform routing? (Choose three.)

• The IP address of a LAN interface on a Layer 3 device provides the default gateway for hosts connected to that LAN.
• A routing protocol must be enabled in order for a Layer 3 device to build a routing table.
• Routing tables are volatile. When power is removed from a Layer 3 device, the routing table ceases to exist.
• A routing table is automatically created for directly connected, active LAN and WAN interfaces.
• A directly connected Layer 3 interface must be manually added to the routing table in order for routing to be enabled on that interface.

Explanation: A routing table entry for a directly connected IPv4 or IPv6 network is automatically added to the routing table when the corresponding interface is up. The interface vlan and ip address commands are used on a switch to assign an IP address to the device. As seen in the chapter content and lab activities, addressing and activating LAN and WAN interfaces automatically trigger the building of a routing table in a Layer 3 device.
