Question #: 2
Topic #: 1
Which of the following statements is false about IP routes?
A.
The optimal route to a specific destination can be determined by only one routing protocol at a certain moment. To determine the optimal route, all routing protocols (including static routing) are configured with priorities.
B.
Direct routes are the routes destined for the network segment to which directly connected interfaces belong.
C.
Each routing protocol can import routes discovered by other routing protocols, direct routes, and static routes.
D.
If routes to the same destination network are discovered by two routing protocols, the cost values of the routes are first compared, and then their priorities.
In Huawei routing principles, route selection follows a strict hierarchy. When multiple routing protocols advertise routes to the same destination, the system first compares the route preference (priority) , not the cost. The route with the lowest preference value (highest priority) is selected. Only within the same routing protocol are cost/metric values compared to determine the best route.
Option A is correct because only one optimal route is installed in the routing table at a time, based on protocol preference. Option B is also correct: direct routes are automatically generated for networks connected to local interfaces. Option C is valid as Huawei devices support route import (redistribution) between routing protocols, enabling flexible network design.
Option D is incorrect because it reverses the decision logic. It incorrectly states that cost is compared before priority, which contradicts Huawei’s routing selection process.
Therefore, the false statement is D .
