What this question is testing
Objective: IP Connectivity
Prompt focus: A router is processing a packet and finds two matching routes in its routing table: a route to 10.1.1.0/24 and a route to 10.1.0.0/16. The destination is 10.1.1.50. Which route does the router use?
Why the correct answer works
The 10.1.1.0/24 route, because the longest prefix match is the most specific route
The router selects the longest prefix match, and 10.1.1.0/24 is more specific than 10.1.0.0/16.
Why the tempting wrong answer fails
The tempting wrong answer usually loses because it skips the key condition, priority, or evidence in the prompt.
Plain-language takeaway
When multiple routes in the routing table match a destination, the router selects the route with the longest prefix match, meaning the most specific route. The destination 10.1.1.50 matches both routes, but 10.1.1.0/24 is more specific than 10.1.0.0/16, so the router uses…
Simple analogy
Think of ip connectivity like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
How to review it before a retake
- Underline the command word and name what the question is asking before rereading the choices.
- Compare the correct answer against the closest distractor and write the exact detail that separates them.
- Retest this objective with a fresh question without looking at the rationale first.
