Surprised that D is even an option, high launch function isn't a must.

C is a bit misleading, low dispersion tolerance isn't a basic requirement.

The launch function being very high sounds familiar, but I don't think that's what they focus on for DWDM systems. I lean towards wavelength stabilization being crucial.

I feel like direct modulation might be relevant, but I don't remember it being a basic requirement. Maybe it's more about the performance of the light source?

I remember practicing a question similar to this, and I think low dispersion tolerance was mentioned as a key factor, but I can't recall if it was the main requirement.

I vaguely remember something about the launch function needing to be high for efficiency, but I’m not confident if that’s a basic requirement for DWDM.

Low dispersion tolerance seems like it could be a factor, but I thought that was more about the fiber itself than the light source.

Hmm, this looks like a tricky one. I'll need to think carefully about the different "Common Tasks" and which ones create tasks in the Physical Inventory work center.

I've got a good strategy for this. I'll eliminate the less effective options first, then focus on the top two choices.

I think this is similar to a question we did in practice about client isolation. Maybe it has to do with forwarding settings?
