Wait, are we sure about A? That sounds too good to be true!

D sounds right, Gbaud rate is 50 for 100G.

C seems off, isn’t it more than 2 bits?

I think B is correct too, same Gbaud rate.

A is definitely true, more bits per symbol!

I believe the Gbaud rate being 50 is incorrect since 100G would typically imply a higher rate, but I need to review that concept again.

I vaguely recall that each symbol in PDM-QSK could represent more than 2 bits, but I can't remember the exact details.

I think the Gbaud rate for 100G 8QAM is also 100, so that might mean option B is true, but I need to double-check that.

I remember studying that PDM-QSK can support higher modulation formats, but I'm not sure if it really exceeds 8QAM in bits per symbol.

This question is testing my knowledge of advanced modulation formats. I'm confident I can work through this by carefully considering the information provided about PDM-QSK and 8QAM.

I'm a bit confused on the differences between these modulation formats. I'll need to review my notes to make sure I understand the key characteristics before selecting an answer.

Alright, I've got this. PDM-QSK supports more bits per symbol per polarization than 8QAM, so I'm going to go with option A.

Okay, let me see here. PDM-QSK is a modulation format, and it's operating at 100G. I'll need to compare that to the characteristics of 8QAM to figure out which statement is correct.

Hmm, this question seems a bit tricky. I'll need to think through the differences between PDM-QSK and 8QAM to determine which statement is true.

This looks like it could be an issue with the VRF instance configuration. I'll check to see if there's an existing VRF instance on the interface and make sure I'm not trying to configure VRF Selection on top of that.

Haha, I'm going with option D just because it's the 'speed limit' for this signal. Who doesn't love a good 50 Gbaud rate?

Option A seems plausible to me. PDM-QSK should be able to support more bits per symbol per polarization than 8QAM.

I think option B is the correct answer. The Gbaud rate for both 100G 8QAM and PDM-QSK is the same, which is 50 Gbaud.
