A1 and 2
-
B2 and 4
-
C3 and 4
-
DAll of the above
Answer
Correct Answer: 1 and 2
Explanation
Introduction / Context:This item checks knowledge of Cisco static route configuration and semantics, including administrative distance and the difference between default routes and specific network routes.
Given Data / Assumptions:
- Statement 1: Command establishes a static route.
- Statement 2: Uses default administrative distance.
- Statement 3: Configures the default route.
- Statement 4: The subnet mask refers to the source address.
Concept / Approach:The form is ip route
Step-by-Step Solution:
Check #1: True. This is a static route to 172.16.4.0/24 via 192.168.4.2.Check #2: True. No distance specified → default AD 1 for static.Check #3: False. Default route would be 0.0.0.0/0, not 172.16.4.0/24.Check #4: False. The mask belongs to the destination prefix, not a source.Verification / Alternative check:Show running-config or show ip route static will reveal AD of 1 unless overridden.
Why Other Options Are Wrong:Any combination including #3 or #4 is incorrect because the command is not a default route and the mask is not a “source” mask.
Common Pitfalls:Confusing source vs destination masks and thinking any ip route equals a default route.
Final Answer:1 and 2
