A manufacturer's plant VLAN cannot reach the maintenance application, while an agent in the headquarters closet still succeeds against the same target. Where should the team place an agent so the test includes the plant failure?
Select an answer to reveal the explanation.
Short Explanation
A green light at headquarters doesn't mean the plant floor is fine. You place the agent inside the plant, on the VLAN that fails, so the test shares the users' broken path. A far-off cloud probe, the headquarters closet that already succeeds, and a laptop at a sales office are all off that VLAN.
Full Explanation
The plant VLAN cannot reach the maintenance application while the headquarters closet still succeeds, so the missing vantage is inside the plant on the VLAN that fails. A test only includes the path in front of the agent, and the headquarters path does not include the break the plant users hit. A cloud probe far from the plant sits outside that VLAN and can succeed in the same way the closet already does. Leaving the only agent in the headquarters closet repeats the test that already succeeds and still misses the plant failure. A laptop at a sales office is off the plant VLAN path and does not represent the users on that VLAN. The outside probe, the closet, and the sales-office laptop are all on paths the plant failure does not cross. Exam caveat: a successful test from headquarters is not evidence that a plant VLAN is healthy. Operational check: run the maintenance-application test from inside the plant VLAN and confirm it fails while the headquarters agent still reaches the same target.
