The Correct Answer: 1, 2 and 5
________________________________________

The correct answers are:
1. The path with the most specific subnet mask
2. The route that has the least administrative distance
5. The route with the lowest metric value
Explanation of Correct Answers:
1. The path with the most specific subnet mask
o When multiple routes exist to the same destination, the one with the longest prefix match (most specific subnet mask) is preferred. This ensures that traffic is routed as precisely as possible.
o Example: If there are two routes to 192.168.1.0, one as 192.168.1.0/24 and another as 192.168.1.0/26, the router selects 192.168.1.0/26 because it is more specific.
2. The route that has the least administrative distance
o The administrative distance (AD) represents the trustworthiness of a route, with lower values being preferred. Different routing protocols have different AD values (e.g., Directly Connected = 0, Static = 1, OSPF = 110, RIP = 120).
o If two routes exist to the same destination but come from different protocols, the router prefers the one with the lower AD.
5. The route with the lowest metric value
o The metric is used within a routing protocol to determine the best path when multiple routes exist. Each protocol has its own metric system (e.g., OSPF uses cost, EIGRP uses bandwidth and delay, RIP uses hop count).
o If two routes have the same prefix length and AD, the one with the lowest metric is chosen.

Why the Other Answers Are Incorrect:
• "The route with the longest metric value"
o A higher metric means a worse path in most routing protocols. The router always prefers routes with the lowest metric because it represents the most optimal path.
• "The path with the highest administrative distance"
o A higher administrative distance means the route is less reliable. The router always selects the route with the lowest AD first.
• "The path with the least specific subnet mask"
o A broader subnet (e.g., /16 instead of /24) is less specific and will only be used if no more specific routes exist. Routers always prefer the most specific match available.
