- The "set ip default next-hop" command verifies the existence of the destination IP address in the routing table: * If the destination IP address exists in the RT, the command does not policy route the packet, but forwards the packet based on the routing table. * If the destination IP address does not exist in the RT, the command policy routes the packet by sending it to the specified next hop. - The "set ip next-hop" command verifies the existence of the destination IP address in the routing table: * If the next hop exists in the routing table, then the command policy routes the packet to the next hop. * If the next hop does not exist in the routing table, the command uses the routing table to forward the packet.

B for sure

The given answer is correct

B is correct

This command specifies the next-hop address to use if there is no explicit route for the destination in the routing table. This is typically used in PBR to specify a default next-hop for packets that do not match any of the other more specific routes in the routing table.

B for sure
