200-301 Show IP Route Output Practice Questions

Explanation: The default route uses a next-hop IP (10.10.10.2) and will only be installed in the routing table if that next-hop is reachable. Since the router’s routing table shows no default route, the most likely cause is that the next-hop 10.10.10.2 is unreachable, preventing the static route from being used. This explains why traffic fails despite the configuration.

Explanation: The static route with an administrative distance of 200 behaves as a floating backup. In plain language, the router keeps it in reserve and prefers the OSPF route while OSPF is healthy, because OSPF’s default administrative distance of 110 is lower and therefore more trusted. The static route does not disappear from the configuration, but it stays out of the active routing table unless the better route is lost. This is a very common CCNA concept because it shows how routing preference works between different route sources. The higher-distance static route is not useless; it is intentionally configured so that it becomes active only during a failure. That design provides backup routing without interfering with the normal dynamic path. The correct answer is the one describing the static route as a standby or floating route rather than as the preferred path.

Explanation: When the same prefix is learned from different routing sources, the router first compares administrative distance (AD). The static route with AD 5 wins over OSPF with AD 110, so option A is correct. Option C is correct because if the static route is removed, the OSPF route becomes the next best candidate and is installed. Option B is wrong since AD is compared before metrics like OSPF cost; a lower cost does not override a lower AD. Option D is wrong because only one route is installed per destination based on AD, not both.

Explanation: The path with the lower OSPF metric is preferred. In practical terms, when the prefix and route source are the same, the router uses the routing protocol’s internal path-selection logic. For OSPF, the lower metric is the more attractive path. This is a clean example of metric-based selection within one routing protocol. Administrative distance is not the deciding factor here because the source protocol is the same on both paths.

Explanation: The static route is preferred because its administrative distance of 90 is lower than OSPF’s default administrative distance of 110. In practical terms, when the prefix length is the same, the router compares route-source trust next. The lower administrative distance wins. This question is important because many learners remember that static routes are often strong choices but forget that administrative distance can be tuned. Here, that tuning explicitly makes the static route more preferred than OSPF.
