The correct answer is C. Change the 10SR optics to 10SR / MMF C-Class XCVR OM4 to support up to 400m / 1312ft. With a fiber distance of 350 m over OM4, the standard 10GBASE-SR optics used in the initial design may only be specified up to 300 m. For 10-Gbps links over OM4 at 350 m, you must use the 10GBASE-SR MMF C-Class transceivers, which are specified to support distances up to 400 m…
Question
Refer to the exhibit. A senior network architect has created the configuration above. You are implementing the set up in building A and B. The actual fiber distance between the building locations is: 350m /1,148ft utilizing OM4 cabling. What needs to be changed on the configuration based on the actual environmental conditions to complete the installation?

Explanation
With a fiber distance of 350 m over OM4, the standard 10GBASE-SR optics used in the initial design may only be specified up to 300 m. For 10-Gbps links over OM4 at 350 m, you must use the 10GBASE-SR MMF C-Class transceivers, which are specified to support distances up to 400 m, ensuring the link operates within supported limits.
