If the NET_ID of the source and destination address in an IP (Internet Protocol) packet match, which answer BEST describes the routing method the sending host will use?

Local (direct) routing occurs when the sending host applies its subnet mask to both source and destination IPs and determines the network IDs are identical, meaning both hosts are on the same network segment. Because no router is needed, the host uses ARP to resolve the destination IP to a MAC address and transmits the frame directly on the local medium. This is the fundamental IP routing decision every host makes before consulting its default gateway.

Circuit switching is a telecommunications method used in traditional telephone networks and is not a mode of IP packet routing based on network ID comparison.

Dynamic routing refers to router-to-router protocols such as OSPF or EIGRP that exchange topology information - it is not a host-level delivery decision based on subnet matching.

Remote (indirect) routing is used when the destination network ID differs from the source, requiring the packet to be forwarded to a default gateway for inter-network delivery.
