Question 450
At the Westhaven public agency, a switch shows routes currently installed but OSPF neighbors have been repeatedly resetting over the past hour. Which underlying issue most directly explains this situation?
Explanation
Correct Answer
The architectural weakness is that snapshot route presence can conceal unstable sessions and transient packet loss. It can be addressed through the controlled change to inspect neighbor event history adjacency uptime and relevant interface logs instead of only the routing table. This result addresses the stated challenge at the Westhaven public agency.
Incorrect Answers
A link can appear operational until optical margins deteriorate enough to cause intermittent failure. This option operates on the following technical behavior: a link can appear operational until optical margins deteriorate enough to cause intermittent failure. The source question instead asks about the control represented by: Snapshot route presence can conceal unstable sessions and transient packet loss. That distinction must be resolved for the requested root-cause explanation.
Backups co-located with the failed site cannot support restoration after a regional disaster. This option operates on the following technical behavior: backups co-located with the failed site cannot support restoration after a regional disaster, rather than merely a monitoring or presentation issue. The source question instead asks about the control represented by: Snapshot route presence can conceal unstable sessions and transient packet loss. That distinction must be resolved for the requested root-cause explanation.
Configuration drift increases security exposure and incident uncertainty between otherwise similar sites.
