Question
A technician is configuring static routing on a router. What is required for the router to forward packets to a specific network?
A. Subnet mask
B. DNS settings
C. Default gateway
D. Next-hop IP address
E. MAC address
Answer
D. Next-hop IP address
Explanation
Static routes require a next-hop IP address to know where to forward traffic.
For a router to forward packets to a specific network using static routing, it must be configured with a next-hop IP address.
The next-hop IP address is the IP address of the next device (typically another router or gateway) to which the router should forward packets destined for a specific network.
When configuring a static route, the administrator specifies the destination network and the next-hop IP address. The router then uses this information to send packets toward their destination by forwarding them to the next-hop device.
If only the next-hop IP address is specified, the router will perform a recursive lookup to determine the appropriate exit interface for that next hop. This process ensures that packets are sent in the correct direction, even if multiple routers are involved in the path to the destination.
Without a next-hop IP address (or an explicitly defined exit interface), the router would not know where to send the packets, and the static route would not function correctly.
A static route requires a next-hop IP address to indicate where the router should forward traffic for a specific destination network.
