The answer to this questions indicates that broadcast traffic will be routed to the 10.0.1.9/28 network via 192.168.0.7. My understanding is that broadcast traffic is not routed. Also the question indicates that the user is attempting to SSH to a specific IP. If the route specified in the answer is correct this connection will fail. The device the user is attempting to communicate with is on the 10.0.1.0/24 network via 192.168.0.4. Where is the flaw in my understanding?

The routing process doesn't care about what service or protocol the traffic is using, if the destination IP fits the subnet, it will route it. You are right that the broadcast traffic isn't routed. However, routing is purely prefix-based. If 10.0.1.15 matches 10.0.1.0/28 (longest match which routes via 192.168.0.7). The router would attempt to route the packet, but the actual transmission may fail (e.g., the target won’t respond, or SSH won't work), yet from the RIB/FIB perspective, the next hop is still 192.168.0.7
