Question
Your customer's employees connected to a wired network are complaining about a poor user experience. The customer has HPE Aruba Networking User Experience Insight (UXI) sensors deployed on their premises. These sensors have been running for multiple months. They are testing both the wired network (using the wired interface of each sensor) and the wireless networks. Your customer used the UXI dashboard to find the reason for the poor user experience. To find more details, the customer asked you to check the packet captures that have been downloaded from the sensors using the UXI dashboard. From the .zip file downloaded from the UXI sensors, you checked the "datagrams" .pcap file, but you were not able to find any issues. How can you explain this?
Options
- AThe default filters of the packet captures do not allow failed tests to be captured by the sensor.
- BThe "datagrams" .pcap file only contains the successful tests. Failed tests are contained in the
- CThe datagrams captured on the physical Ethernet interface are in a different .pcap file.
- DThe UXI sensor could not upload the latest test results to the cloud, so the packet capture is

Explanation
Option B is correct because HPE Aruba UXI separates packet captures by test outcome: the "datagrams" .pcap file contains only successful test traffic. Since the employees are experiencing poor performance, the relevant evidence lives in a separate .pcap file for failed tests - which is why the datagrams file appeared clean.
Why the distractors are wrong:
- A is wrong - default filters do not block failed tests from being captured; they are captured, just stored in a different file, not excluded entirely.
- C is wrong - the split between .pcap files is based on test outcome (pass/fail), not on which physical interface (wired vs. wireless) was used.
- D is wrong - the customer successfully downloaded the .zip file from the UXI dashboard, which confirms the sensor did upload data to the cloud. An upload failure would have prevented the download entirely.
Memory tip: Think of UXI packet captures as two buckets - a "green bucket" (datagrams = successful tests) and a "red bucket" (failed tests). When users complain, always check the red bucket. Finding nothing wrong in the green bucket is expected - that's exactly where you wouldn't see failures.
