At a SaaS company, two probes test the same application for remote staff. Only the probe behind a congested firewall shows loss, and the other probe stays clean. What does that pattern identify?
Select an answer to reveal the explanation.
Short Explanation
Two weather stations matter only if you notice which one sits behind the hill. You treat the loss as the firewall path, because only the probe behind that congested firewall shows it. A browser bug on every client, a DNS-only fault, and a wireless ticket don't explain a clean probe beside a dirty one.
Full Explanation
Two probes test the same application and only the probe behind a congested firewall shows loss, so the difference is the firewall path. The clean probe shows the application is reachable from the other vantage, which removes a fault that would hit every test. A browser bug on every client would not leave one probe clean and the other lossy, because both probes are exercising the same application. A DNS-only fault would stop name resolution before a stable comparison, and both probes are already testing the application with loss on only one path. A wireless ticket for the remote staff would fit a local radio problem, and the split here follows the firewall rather than the radio. The browser, the resolver, and the radio do not explain why one vantage stays clean. A fault shared by every test would have shown loss on the clean probe as well, and it did not. Exam caveat: when two probes disagree, follow the path that only the failing probe traverses. Operational check: compare the hops each probe sees and confirm the loss is confined to the path through that congested firewall.
