200-301 · Question #968
Refer to the exhibit. A network engineer must configure router R1 with a host route to the server. Which command must the engineer configure?
The correct answer is B. R1(Config)#ip route 10.10.10.10 265.255.255.255 192.168.0.2. To configure a host route on R1 for the server, the command specifies the exact server IP address with a /32 subnet mask and the next-hop IP address to reach that server. This ensures traffic to that specific host is routed directly via the specified next hop.

Why each option
To configure a host route on R1 for the server, the command specifies the exact server IP address with a /32 subnet mask and the next-hop IP address to reach that server. This ensures traffic to that specific host is routed directly via the specified next hop.
This command configures a network route for the 10.10.10.0/24 network, not a specific host route for 10.10.10.10.
A host route specifically targets a single IP address, which requires a /32 subnet mask (255.255.255.255). The command `ip route 10.10.10.10 255.255.255.255 192.168.0.2` correctly specifies the destination host IP (10.10.10.10), its /32 mask, and the next-hop IP address (192.168.0.2) that R1 should use to reach the server.
This command specifies the next-hop address (192.168.0.2) as the destination and the server's IP (10.10.10.10) as the next-hop, which is inverted and incorrect for reaching the server.
This command configures a default route, which sends all traffic with no specific route to 192.168.0.2, not a specific host route to the server.
