Discuss Nokia 4A0-205 Exam Topic 6 Question 40

Which of the following sentences about FlexGrid is false?

AFlexGrid allows a more efficient channel spacing.

BChannels in FlexGrid systems are allocated with a granularity of 27.5GHz.

CFlexGrid systems use specific sets of boards. Old generation WDM systems need to be upgraded to support FlexGrid.

DThe FlexGrid is currently standardized by ITU-T.

Suggested Answer: C

FlexGrid is a flexible grid technology that allows for variable channel spacing and bandwidth allocation. It uses the same sets of boards as the traditional fixed grid systems and it does not require upgrading the old generation WDM systems.

C sounds right, old systems do need upgrades for FlexGrid.

Luisa 11 months ago

B is correct, 27.5GHz granularity is a fact.

Cyril 11 months ago

Wait, is D really standardized? I thought it was still in the works.

Lacey 11 months ago

I agree, A is definitely true!

Mike 12 months ago

FlexGrid does allow for more efficient channel spacing.

Marva 12 months ago

I’m pretty sure that the FlexGrid standardization by ITU-T is a recent development, but I can't recall the exact details.

Juliann 1 year ago

I practiced a similar question where it mentioned that older WDM systems need upgrades for FlexGrid, so I think that part is true.

Rosendo 1 year ago

I remember something about the granularity being 50GHz, not 27.5GHz, but I could be mixing it up with another system.

Mari 1 year ago

I think FlexGrid does allow for more efficient channel spacing, but I'm not completely sure about the specifics.

Pansy 1 year ago

D seems like the most likely false statement. I don't recall seeing anything about FlexGrid being standardized by ITU-T, so that part seems questionable to me.

Louisa 1 year ago

The question mentions that FlexGrid systems use specific sets of boards, so I think C might be the false statement. Old WDM systems would need to be upgraded to support the new FlexGrid technology.

Karl 1 year ago

Hmm, I'm a bit confused about the differences between FlexGrid and traditional WDM systems. I'll need to review the details on channel allocation and standards to decide which one is false.

Daniel 1 year ago

I'm pretty sure the answer is A, since FlexGrid is supposed to allow more efficient channel spacing compared to older WDM systems.

Nadine 1 year ago

Okay, let's see. I know free licenses don't support clustering, so I can rule out option A. But the other options seem a bit more complex.

Georgiana 2 years ago

Actually, I think you're right. The FlexGrid is currently standardized by ITU-T, so that statement must be false.

Kindra 2 years ago

I disagree, I believe the false statement is about FlexGrid systems using specific sets of boards.

Lynelle 2 years ago

Ooh, this question is a real flex for the FlexGrid experts! Let's hope we don't get gridlocked on the correct answer.

Kiera 2 years ago

↳ replying to Lynelle

A) FlexGrid allows a more efficient channel spacing.

Barbra 2 years ago

D is the false statement here. The FlexGrid is standardized by ITU-T, not some other organization.

Gene 2 years ago

↳ replying to Barbra

Definitely, D is the false statement. ITU-T is the one that standardizes FlexGrid.

Cyril 2 years ago

↳ replying to Barbra

Yes, D is incorrect. ITU-T is the organization that standardizes FlexGrid.

Eun 2 years ago

↳ replying to Barbra

I agree, D is the false statement. The FlexGrid is standardized by ITU-T.

Paulina 2 years ago

↳ replying to Barbra

A) FlexGrid allows a more efficient channel spacing.

Lavelle 2 years ago

C seems false to me. Old generation WDM systems don't necessarily need to be upgraded to support FlexGrid. The technology can be used in new systems as well.

Lino 2 years ago

↳ replying to Lavelle

So, the false statement is C.

Blondell 2 years ago

↳ replying to Lavelle

Yes, D is correct. FlexGrid is currently standardized by ITU-T.

Benton 2 years ago

↳ replying to Lavelle

FlexGrid is standardized by ITU-T, right?

Lorrine 2 years ago

↳ replying to Lavelle

I think C is false too. FlexGrid can be used in new systems without upgrading old ones.

Georgiana 2 years ago

I think the false statement is about FlexGrid allowing a more efficient channel spacing.

Marget 2 years ago

I'm pretty sure the correct answer is B. The channels in FlexGrid systems are allocated with a granularity of 27.5 GHz, not the other options.

Barrett 2 years ago

↳ replying to Marget

That makes sense. The other options don't seem to match up with how FlexGrid works.

Barrett 2 years ago

↳ replying to Marget

I think you're right. B) Channels in FlexGrid systems are allocated with a granularity of 27.5GHz.
