HPE7-A03 Exam - Topic 4 Question 29 Discussion

Actual exam question for HP's HPE7-A03 exam
Question #: 29
Topic #: 4
[All HPE7-A03 Questions]

when is o Mode Conditioning Patch Cable required?

Show Suggested Answer Hide Answer
Suggested Answer: B

Option B is the most cost-effective solution, as it does not include long-range optics, which are unnecessary given the distances and fiber types specified. The 10GbE-SR optics are suitable for short-range connections up to 300 meters over OM3 fiber and would cover the needs of the longest fiber run mentioned, which is 250 meters. The 10GbE-LRM optics, while capable of reaching up to 220 meters over OM2 fiber, would not be necessary as the longest OM2 run is 71 meters, which is within the range of standard 10GbE-SR optics. Thus, Option B provides the required connectivity without incurring additional costs for long-range optics that are not needed given the fiber infrastructure of HQ2.

I think option D sounds right because I remember 10GBase-LR being associated with 500 m, but I could be mixing it up with something else.
