When multiple routes exist to the same destination, which would be installed in the routing table?
- A. Highest administrative distance.
- B. Default route.
- C. Static route.
- D. Lowest administrative distance.
Answer: D
Explanation:
When multiple routes to the same destination are available, the route with the lowest administrative distance is preferred and installed in the routing table because it is considered the most trustworthy source.
