Question 530
During a planned campus-network change at a university faculty building in Boston, operators discover that a narrow static route is shadowed by a more-specific incorrect prefix on a distribution switch. The design must preserve teaching tools and shared printers. Which post-change observation is the strongest acceptance evidence?
Explanation
Correct Answer
This observation tests the Static/default route and route preference requirement at a university faculty building in Boston. The expected result is that the intended destination resolves through the authorized next hop and no unwanted default-route black hole remains. The necessary correction is to install the correct destination prefix and reachable next hop, then validate route preference before expecting application reachability; a saved configuration alone would not prove it is working. In this case, the observed fault is that a narrow static route is shadowed by a more-specific incorrect prefix on a distribution switch.
Incorrect Answers
At a university faculty building in Boston, this measures a different network requirement, OSPF path metric and convergence. The case describes that a narrow static route is shadowed by a more-specific incorrect prefix on a distribution switch, so accepting this result would leave the primary fault without direct verification.
At a university faculty building in Boston, this would verify Dynamic route filtering and redistribution, not the failure reported in this scenario. The requested closure criterion instead concerns Static/default route and route preference: the intended destination resolves through the authorized next hop and no unwanted default-route black hole remains.
At a university faculty building in Boston, the observation may be useful for a separate DHCP relay and inter-subnet services test, but it does not establish that a narrow static route is shadowed by a more-specific incorrect prefix on a distribution switch has been resolved. The relevant check is the Static/default route and route preference outcome.
