Question #: 34
Topic #: 4

[All 4A0-205 Questions]

Which of the following are the main reasons for fiber attenuation?

ARefraction and reflection

BScattering and absorption

CChromatic dispersion (CD) and polarization mode dispersion

DSmall channel spacing

Show Suggested Answer

Suggested Answer: B

No, it is not possible to mix PSS-24x and PSS-8x shelves in an SWDM (Short Wavelength Division Multiplexing) configuration. The two shelves are not compatible, and cannot be used within the same node.

Agreed, B is the main reason for fiber attenuation!

I thought refraction was the main issue, not just reflection.

Wait, small channel spacing? That seems off.

A and C are also important, though!

Definitely B, scattering and absorption are key!

I feel like small channel spacing might be more about capacity than attenuation, but I could be mixing it up with something else I studied.

Chromatic dispersion sounds familiar, but I can't recall if it's a main reason for attenuation or just a related issue.

I remember practicing a question about this, and I think refraction and reflection were mentioned, but they seemed less significant compared to scattering and absorption.

I think fiber attenuation is mainly due to scattering and absorption, but I'm not entirely sure if refraction plays a role too.

For this type of question, I usually try to think about the physical processes involved in fiber optic transmission. Scattering and absorption seem like the most likely culprits, so I'll go with option B.

I'm a bit confused by this question. I know fiber attenuation is an important topic, but I'm not sure if I can confidently identify all the main reasons. I'll have to review my notes and try to eliminate the less likely options.

Okay, let's see. I remember from the lectures that chromatic dispersion and polarization mode dispersion can also cause fiber attenuation, so I'll go with option C.

Hmm, this is a tricky one. I'm not sure if I should go with scattering and absorption or refraction and reflection. I'll have to think this through carefully.

I'm pretty confident that the main reasons for fiber attenuation are scattering and absorption, so I'll go with option B.

Hmm, I'm a bit confused about the difference between the options here. I know we need to restrict access to the high-risk price book, but I'm not sure if manual sharing or a sharing rule is the better approach.

I'm a bit confused here. The question is about planning for the administration of resources in Azure, but the underlined text is about implementing AD FS. I'm not sure if that's the right approach, so I'll need to think this through carefully.
