At a university, an Enterprise Agent in the data center reaches the learning application, but a branch laptop aimed at the same target does not. Which test should be added?
Select an answer to reveal the explanation.
Short Explanation
The lobby phone works and the dorm phone does not, so you test from the dorm. Add an Endpoint Agent test on the branch laptop that cannot reach the application the data-center probe already reaches. Another Enterprise Agent beside that probe, a cloud DNS test, or a page load that stays in the data center never stands where the failure is.
Full Explanation
The data-center Enterprise Agent can reach the learning application, and the branch laptop aimed at the same target cannot, so the missing measurement is on the laptop. An Endpoint Agent test on that branch laptop runs where the failure is observed and can include the local network in front of the user. Another Enterprise Agent placed in the data center next to the working probe duplicates a vantage point that already succeeds and will not explain the laptop. A DNS test from a cloud probe that is not sitting on the branch laptop measures name resolution from the cloud, a location that is neither the data center probe nor the branch laptop. A page-load test in the data center that never runs on that laptop repeats the successful data-center path in a browser and never executes on the device that fails. Exam caveat: same target and different result means the vantage point is the variable, and the healthy probe is the one you do not keep cloning. Operational check: start the Endpoint Agent test on the branch laptop toward the same application, confirm it fails there, and confirm the data-center Enterprise Agent still succeeds during that attempt.
